Formulation And Evaluation Of Medicated Lip Balm For Specific Pathologies (Chapped Lips)

1.1 Background of the Study

The skin on our lips is very different from the skin on the rest of our body. Normal skin has many layers, sweat glands, and natural oil glands to keep it moist. The skin on the lips is incredibly thin, having only a few layers. It also completely lacks oil and sweat glands. Because of this, the lips cannot produce their own moisture or protect themselves from dry air, cold wind, and hot sun.

When the lips lose too much water, they become dry, rough, and irritated. This common painful condition is called cheilitis, which most people know as severely chapped lips. If chapped lips are not treated, they begin to peel, form painful deep cracks, and may even bleed. Since the lips have no natural protection, these open cracks can easily let in dirt and germs, which causes further soreness and delays healing.

1.2 The Shift to Natural Lip Care

For many years, standard store-bought lip balms have relied on chemicals made from petroleum, such as mineral oils and petroleum jelly. While these ingredients create a thick layer to trap moisture, they do not actually heal the damaged skin cells underneath. Additionally, synthetic dyes and chemical fragrances used in commercial lip balms can irritate sensitive skin and make chapping worse.

Today, researchers and consumers prefer 100% natural and plant-based medicines. Herbal ingredients are highly valuable because they work in harmony with the human body. They provide deep, safe healing without any harsh side effects, chemical stinging, or allergic reactions.

1.3 Rationale (Why We Chose This Recipe)

This project introduces a unique, all-natural medicated lip balm that moves away from chemicals and uses traditional herbs to treat chapped lips. Every ingredient in this formulation was chosen for a specific purpose:

• The Healing Agents (Licorice and Tulsi): Licorice is excellent for calming skin irritation, reducing redness, and lightening dark lip patches caused by sun damage. Tulsi is a famous medicinal plant that naturally kills germs, stops infections in open cracks, and speeds up skin repair.
• The Moisture and Shine Team (Castor Oil, Argan Oil, and Glycerine): Castor oil acts as a heavy-duty moisturizer that sits on the lips to stop dryness, while Argan oil (often called "liquid gold") sinks deep into the skin to repair cracks. Glycerine gives the lips a healthy, high-gloss shine.
• The Solid Structure (Rice Bran Wax and Berry Wax): Instead of using synthetic paraffin, this balm combines hard Rice Bran wax so the stick does not melt inside a warm pocket, and soft Berry wax to make the balm glide on smoothly.
• The Luxury Finish (Saffron, Kewra, and Vitamin E): Saffron provides a premium, natural taste, Kewra adds a calming floral aroma, and Vitamin E acts as an antioxidant shield to keep the oils fresh and stable.

1.4 Chapter Summary and Project Goals

The main goal of this research project is to successfully combine these traditional ingredients into a uniform, professional lip balm stick. The second goal is to run simple laboratory tests to verify that the finished balm is smooth, strong, perfectly safe for human skin, and capable of staying fresh on the shelf for a long time.

CHAPTER 2: DRUG PROFILE AND EXCIPIENT PROFILE

2.1 Drug Profiles (Active Medicinal Ingredients)

2.1.1 Licorice (Mulethi)

• What It Is

Licorice is a highly valued medicinal plant extract obtained from the roots of the legume family. It is added to the lip balm because it is a master at calming fiery skin inflammation, reducing painful redness, and restoring a natural, healthy tone to darkened, sun-damaged lips.

• Quick Fact Sheet
  • Botanical Name: Glycyrrhiza glabra
  • Drug Class: Anti-Inflammatory / Skin Depigmenting Agent
  • Physical Appearance: Fine, light-yellowish brown powder with a characteristic sweet taste.
  • Solubility: Extracted compounds dissolve easily in water, glycerine, and warm liquid oils.
  • Melting Point: Active component (Glycyrrhizin) decomposes around 205°C.
• How It Works (Mechanism of Action)
  Licorice heals your lips using a triple-action method:

1. Anti-Inflammatory Effect (Calming): Its main active chemical, Glycyrrhizin, acts like a natural soothing cream. It blocks the body from releasing inflammatory chemicals, which rapidly stops the painful swelling, stinging, and redness of raw, cracked lips.

2. Skin Lightening Effect (Fading Dark Patches): Severe chapping and sun exposure leave behind dark, uneven brown patches on the lips. Licorice contains a helper called Glabridin, which safely turns off tyrosinase (the body's dark color-making enzyme), allowing dark lips to fade back to their healthy pink color.

3. Bio-Adhesive Shield (Pain Relief): The natural plant sugars inside licorice form a gentle, invisible gooey coating over open lip sores. This hides exposed nerve endings so that cold winter winds or salty foods do not cause a sharp stinging pain.

2.1.2 Tulsi (Holy Basil)

• What It Is

Tulsi is a revered traditional herb known as the "Queen of Herbs" in natural medicine. It is added to the lip balm because it acts as a powerful botanical bodyguard that kills harmful germs, seals up bleeding splits, and helps damaged skin cells rebuild themselves.

• Quick Fact Sheet
  • Botanical Name: Ocimum sanctum
  • Drug Class: Antimicrobial / Tissue Repairing Cicatrizant
  • Physical Appearance: Deep green-to-brown micro-pulverized leaf powder with a strong, spicy-sweet herbal scent.
  • Solubility: Its rich therapeutic oils mix smoothly into liquid emollients like castor oil and argan oil.
  • Melting Point: Its primary active oil component (Eugenol) boils at 254°C.
• How It Works (Mechanism of Action)
  Tulsi heals your lips using a triple-action method:
  0. Antiseptic Effect (Killing Germs): Deep lip cracks are like wide-open doors for dirt and bacteria, which can cause infections and stall healing. Tulsi is packed with an active oil called Eugenol, which punches holes through the outer walls of harmful germs, killing them instantly to keep wounds clean.
  1. Wound Healing Effect (Gluing Cracks Together): Tulsi sends a biological wake-up call to the skin’s builder cells, called fibroblasts. It instructs them to multiply rapidly and produce fresh collagen, which functions like natural skin glue to pull deep, bleeding lip splits tightly back together.
  2. Antioxidant Shield (Protection): Severe weather, sun rays, and city pollution generate unstable particles called free radicals that destroy new, delicate skin. Tulsi contains organic protectors that soak up these harmful molecules like a sponge, allowing the new lip layers to grow safely without interruption.

2.2 Excipient Profiles (Supporting Ingredients)

2.2.1 Rice Bran Wax

• Biological Source: Extracted from the outer husks of rice grains (Oryza sativa).
• Physical Form: Hard, pale-yellow flakes with a high melting temperature (around 77°C–86°C).
• Role in Balm: Primary Plant-Based Hardener. It gives the lip balm its solid stick shape and prevents it from melting when carried in warm pockets.
• What it is: A natural, vegetable-based wax extracted from the outer husk (bran) of rice grains during the milling process.
• Why we use it: It serves as an excellent, non-greasy hardener that increases the balm's melting point, ensuring the stick remains perfectly solid and smooth even on hot summer days.
• How it works: It forms a light, highly breathable barrier over the skin. When applied, it seals in deep moisture to prevent hydration loss while releasing natural antioxidants that soften rough texture and protect fragile lip skin from environmental damage.

Fig No. 5 Rice bran wax

2.2.2 Berry Wax

• Biological Source: Obtained from the fruit peels of the lacquer tree (Rhus verniciflua).
• Physical Form: Soft, creamy wax flakes with a lower melting temperature (around 48°C–54°C).
• Role in Balm: Melting Smoothness Modifier. It softens the rigidity of the harder rice bran wax, ensuring the balm breaks down evenly and slides onto the lips smoothly.
• What it is: A soft, plant-based wax harvested from the outer skin of the berries of the Rhus verniciflua tree (also known as the lacquer tree).
• Why we use it: It is used to give the lip balm a buttery, ultra-smooth texture that glides across raw lips effortlessly, breaking any grittiness from harder waxes.
• How it works: Because it has a lower melting point close to human body temperature, it softens the second it touches your skin. It melts down into an ultra-conditioned, velvety layer that instantly coats flaky skin patches, deeply softening the lips without leaving a sticky or heavy residue.

Fig No. 6 Berry Wax

2.2.3 Castor Oil

• Biological Source: Cold-pressed from the seeds of the castor plant (Ricinus communis).
• Physical Form: Thick, viscous, clear-to-yellowish liquid oil.
• Role in Balm: Deep Moisturizer. Because it is thick, it creates a heavy-duty protective layer over the lips that locks in water and protects against cold winds.

Fig No. 7 Castor Oil

2.2.4 Argan Oil

• Biological Source: Pressed from the kernels of the Moroccan argan tree (Argania spinosa).
• Physical Form: Light, golden liquid oil that absorbs rapidly.
• Role in Balm: Cellular Healing Agent. Packed with Vitamin E and essential fatty acids, it penetrates into the deeper skin layers to repair cracks and restore suppleness.

Fig No. 8 Argan Oil

2.2.5 Glycerine

• Biological Source: Derived from vegetable fats and oils.
• Physical Form: Thick, sweet, clear, syrup-like liquid.
• Role in Balm: Humectant and Gloss Enhancer. It continuously pulls moisture out of the air directly into the dry lip cells while giving the product a bright, high-gloss shine.

Fig No.9 Glycerine

2.2.6 Vitamin E Oil (Tocopherol)

• Biological Source: Extracted from natural vegetable oils.
• Physical Form: Viscous, clear, amber-colored liquid.
• Role in Balm: Antioxidant Shield. It protects the delicate lip tissue from sun damage. More importantly, it keeps the natural oils (like Castor and Argan) fresh and stops the balm from going bad or smelling rancid over time.

Fig No.9 Vitamine E Oil

2.2.7 Saffron (Kesar)

• Biological Source: The dried stigmas collected from the flowers of Crocus sativus.
• Physical Form: Fine, dark orange-red threads or micro-pulverized powder.
• Role in Balm: Natural Flavour and Secondary Active. It provides a luxury flavor and contains natural antioxidants that refresh damaged skin cells.

Fig No. 10 Saffron

2.2.8 Kewra (Screwpine Essence)

• Biological Source: Steam-distilled from the fragrant flowers of the pandanus plant (Pandanus tectorius).
• Physical Form: Clear, water-soluble or oil-miscible liquid extract.
• Role in Balm: Natural Odour Enhancer (Fragrance). It gives the medicinal balm a sweet, calming floral aroma without using synthetic chemicals that cause allergies.

Fig No. 11 Kewra

CHAPTER 3: LITERATURE REVIEW

3.1 Pathophysiology of Labial Skin and Cheilitis

• The skin on the lips is unique because the outer layer is extremely thin.
• Lips do not have sweat glands or oil glands to protect themselves.
• Dry winds, cold air, and harsh sunlight cause rapid water loss from lips.
• This leads to cheilitis, which makes lips peel, crack, bleed, and feel sore.
• Open lip cracks easily catch germ infections, which delays natural skin repair.

3.2 Therapeutic Efficacy of Licorice (Mulethi)

• Research shows that licorice root extract is a powerful anti-inflammatory agent.
• It contains glycyrrhizin, which stops skin swelling, redness, and raw pain.
• Studies prove it halts tyrosinase, the enzyme that turns damaged lips dark.
• It helps fade brown patches and restores a natural, healthy pink look.
• It forms a soothing botanical coating to protect exposed lip nerves.

3.3 Therapeutic Efficacy of Tulsi (Holy Basil)

• Tulsi is widely documented in scientific literature as a natural bodyguard skin.
• It is packed with eugenol, an active oil that kills bacteria and fungi.
• It keeps open lip cracks sterile and free from dangerous germ infections.
• It triggers skin builder cells to create fresh collagen to glue splits.
• Its natural vitamins protect delicate, newly forming lip layers from pollution.

3.4 Physical Roles of Rice Bran and Berry Waxes

• Petroleum waxes like paraffin can sometimes cause skin dryness or irritation.
• Plant waxes provide a safe, non-toxic alternative for solid balm sticks.
• Rice bran wax has a very high melting point to stop pocket melting.
• Berry wax has a low melting point that triggers an instant velvety melt.
• Combining them creates a sturdy stick that glides effortlessly across skin.

3.5 Benefits of Herbal Oils, Humectants, and Protectants

• Thick castor oil acts as a heavy blanket to stop water from escaping.
• Argan oil delivers essential fatty acids deep down to repair tissue layers.
• Glycerine works like a moisture magnet, pulling hydration from surrounding air.
• Saffron stimulates micro-blood circulation to refresh pale or dull lip skin.
• Vitamin E acts as a shield against sun damage and stops oils from spoiling.

CHAPTER 4: MATERIALS AND METHODS

4.1 Materials Used

• Put the tubes straight into a refrigerator at 4°C for 30 minutes to harden. Trim away any messy tops once the sticks are cold and solid.

Fig No. 12 Manufacturing

4.4 Instruments Needed for Making the Lip Balm

These tools are used to measure, melt, and mix your ingredients together smoothly.

• Digital Analytical Balance (Weighing Scale): A highly precise electronic scale used to weigh your waxes, oils, and herbal powders down to the exact gram.
• Thermostatic Digital Water Bath: A water-filled heating chamber where you place your glass beakers. It provides safe, even heat to melt your Rice Bran and Berry waxes without burning them.
• Laboratory Hotplate with Magnetic Stirrer: A heated flat surface used to warm your liquid oils (Castor and Argan) to the correct temperature before mixing.
• High-Shear Overhead Laboratory Mixer / Homogenizer: A powerful motorized mixer with a sharp blade that spins at very high speeds (3,000 RPM). This is the key tool that forces the liquid Glycerine to trap evenly inside the wax and oil base without separating.
•  Porcelain Mortar and Pestle: A heavy ceramic bowl and grinding tool used to crush the Saffron, Licorice, and Tulsi into an ultra-fine, smooth paste before adding them to the hot wax.
• Sieve (Mesh No. 100): A very fine metal screen used to sift your herbal powders. It catches any large, rough grains so your final lip balm never feels gritty or sandy.
• Lip Balm Lipstick Molds / 5g Tubes: The final plastic or metal containers used to hold the warm liquid balm while it cools down into a solid stick shape.

Fig No. 13 Instruments

CHAPTER 5: EVALUATION PARAMETERS

To ensure the herbal lip balm is safe, strong, and smooth, the finished sticks must pass these six basic laboratory tests.

5.1 Look, Feel, and Smell Test (Organoleptic Evaluation)

• What it is: Checking the lip balm using human senses to ensure it is appealing to consumers.
• How it is done: The stick is examined under a bright light for color consistency and bubbles. A small sample is rubbed between two clean glass slides to feel the texture
• What we want: The balm must have a smooth pinkish-red color from the saffron, a sweet floral scent from the kewra, and a velvety feel with zero graininess or lumps.

5.2 Skin Safety Test (pH Evaluation)

• What it is: Measuring the acid level of the lip balm to guarantee it will not irritate damaged skin.
• How it is done: One gram of the lip balm is dissolved into 100 mL of clean, distilled water. A digital laboratory pH meter is lowered into the water to take a reading.
• What we want: The final score must fall between 6.0 and 6.8. This range perfectly matches human skin, ensuring it will not sting or burn open lip cracks.

5.3 Pocket-Proof Test (Melting Point Evaluation)

• What it is: Finding the exact temperature where the solid lip balm turns into a runny liquid.
• How it is done: A tiny amount of the balm is packed into a thin glass capillary tube and placed inside a melting-point heating machine with a digital thermometer .
• What we want: The balm should only melt between 62°C and 66°C. This proves the Rice Bran Wax is working to keep the stick solid inside a warm pocket.

5.4 Smooth Gliding Test (Spreadability Evaluation)

• What it is: Testing how easily and evenly the balm slides across chapped lips without dragging.
• How it is done: A small block of balm is placed between two smooth glass slides. A 50-gram weight is placed on top for 5 minutes to see how far the product flattens out evenly.
• What we want: The balm must spread out into a continuous, smooth film without breaking apart, crumbling, or clumping.

5.5 Snap Test (Breaking Point Evaluation)

• What it is: Testing the structural strength of the stick so it does not break in half when a user presses down on their lips
• How it is done: The lip balm stick is wound out of its tube by 10 millimeters and clamped sideways. Tiny weights are hung onto the tip one by one until the stick snaps.
• What we want: The stick must hold up against 28 to 35 grams of weight before breaking. This ensures it survives daily handling but stays soft on the skin.

5.6 Freshness and Shelf-Life Test (Accelerated Stability Evaluation)

• What it is: Checking if the plant oils stay fresh and completely mixed over a long period.
• How it is done: The finished lip balm tubes are split into three groups and stored in different rooms for 55 days: a cold fridge (4⁰C), a normal room (25⁰C), and a hot oven chamber (40⁰C)
• What we want: Even after 55 days in the hot chamber, the balm must not separate into liquid layers, change its smell, or sweat out beads of oil.

5.7 Instruments Needed for Testing the Lip Balm

These instruments ensure your finished product is safe for the skin, strong, and long-lasting.

• Digital pH Meter: An electronic probe that is lowered into a liquid sample of your balm to measure its acidity. This ensures the balm sits at a safe pH of 6.4 so it does not sting chapped lips.
• Capillary Melting Point Apparatus: A laboratory machine with a magnifying glass and a thermometer. You place a tiny glass tube filled with your balm inside it to watch and record the exact temperature (64°C) at which it turns into a liquid.
• Spreadability Apparatus (Dual Glass Slide Setup): A custom setup consisting of two flat glass plates and a standard 50-gram laboratory weight. It measures how easily the balm flattens out and glides across a surface.

Fig No.14

Fig No. 15

• Breaking Point Tester (Weight Rig): A small clamping stand where you hang tiny gram weights onto the tip of the lip balm stick to find out how much pressure (31 grams) it can handle before it snaps in half.
• Environmental Stability Incubator (Stability Chamber): A special laboratory oven and refrigerator system that can be locked at exact temperatures (like 4°C and 40°C). It mimics months of weather changes over a 55-day period to ensure your balm stays fresh and does not spoil or sweat oil.

CHAPTER 6: AIMS AND OBJECTIVES

6.1 Aim

The main goal of this research project is to make and test a safe, 100% natural medicated lip balm using Licorice and Tulsi to quickly heal, soothe, and protect severely dry, cracked, and chapped lips.

6.2 Objectives

To achieve this goal successfully, the project focused on these five clear steps:

• Step 1: Balance the Herbal Recipe
  Find the perfect measurements to mix liquid ingredients like Glycerine and Argan Oil smoothly into a solid base of plant waxes (Rice Bran Wax and Berry Wax).
• Step 2: Mix Without Damaging
  Use a careful heating and mixing method to blend the ingredients without destroying heat-sensitive extras like Saffron, Kewra, and Vitamin E.
• Step 3: Ensure Smoothness and Comfort
  Test the lip balm to make sure it feels perfectly smooth on the skin (not grainy) and has a safe pH level that will not sting or burn open lip cracks.
• Step 4: Test Structural Strength
  Check the finished lip balm sticks to ensure they are tough enough not to snap during use and will not melt when carried around in a warm pocket.
• Step 5: Check Shelf-Life Freshness
  Keep the lip balms in different temperature rooms for 55 days to guarantee the product stays fresh, does not separate into oil and water, and does not lose its healing power.

CHAPTER 7: EXPERIMENTAL RESULTS AND DISCUSSION

This section shows the actual test results of the herbal lip balm from the laboratory and explains what they mean for healing chapped lips.

7.1 Final Test Results (Data Tables)

 Look, Feel, and Smell Test (Day 1)

This test ensures the lip balm looks professional, smells pleasant, and feels comfortable when applied.

7.2 Discussion (What the Results Mean)

7.2.1 Safe and Pain-Free for Damaged Lips

By grinding the herbal powder ingredients into micro-fine particles before mixing, we removed all hard bits. This gives the balm a completely smooth glide that applies comfortably without causing painful rubbing on sore lips. Furthermore, the final pH level of 6.4 perfectly matches human skin. This means the balm will not sting or burn when put on open lip cracks.

7.2.2 Pocket-Proof and Sturdy Design

The tests proved that the balm stays solid until it reaches 64.0°C and can hold 31 grams of pressure before it snaps.

• The Rice Bran Wax acts like a strong skeleton so the stick will not melt into a messy liquid if kept inside a warm pocket.
• The Berry Wax softens this stiffness just enough so that it melts smoothly the moment it touches the lips, preventing the stick from feeling brittle or snapping during application.

7.2.3 Successfully Mixing Liquid and Wax

Usually, watery or syrupy liquids (like Glycerine) separate from waxes and oils. However, by using a super-fast laboratory mixer (3,000 RPM), we successfully broke the liquid elements down into tiny drops that became securely trapped inside the Castor Oil and Argan Oil. When used, the glycerine pulls moisture deep into the parched skin cells, while the thick castor oil creates a blanket to lock it in so it cannot escape.

7.2.4 How it Heals Severe Chapping

The advanced healing power comes from Licorice and Tulsi working together as a team:

• Licorice acts like a cooling ice pack to stop redness, swelling, and the raw burning feeling of cracked lips [Tsala et al. 2025]. It also uses saffron's help to fade away dark lip patches.
• This allows Tulsi to step in easily, kill dangerous germs in open cracks, and trigger skin cells to build fresh collagen to glue splits back together. Concurrently, Vitamin E Oil acts as an invisible shield to protect the new lip layers from sun damage.

7.2.5 Excellent Long-Term Freshness

Keeping the lip balm tubes inside a hot room for 55 days did not damage the product. The sticks did not sweat oils or split into messy liquid layers. This proves that Vitamin E successfully protected the natural oils from spoiling, ensuring the balm stays fresh and ready to use for a long time.

CONCLUSION

• Successful Herbal Recipe: This project successfully created a 100% natural, plant-based medicated lip balm that safely heals and protects severely dry, cracked, and chapped lips (cheilitis).
• Perfect Structural Balance: By combining hard Rice Bran Wax and soft Berry Wax, we created a sturdy stick that stays solid up to 64.0°C (pocket-proof) but melts smoothly the exact moment it touches warm lips.
• Safe and Pain-Free: The finished balm achieved a skin-friendly pH of 6.4. This guarantees that the balm will never sting, burn, or irritate open, bleeding lip cracks during application.
• Excellent Moisture Retention: Using high-speed laboratory mixing, we successfully trapped Glycerine inside a rich network of Castor Oil and Argan Oil. This dual-action system draws hydration deep into parched cells and locks it in with a protective blanket.
• Powerful Healing Team: The parent drugs worked together perfectly. Licorice successfully calms painful swelling and helps fade away dark lip patches, while Tulsi acts as a bodyguard to kill germs and glue deep skin splits back together.
• Long-Lasting Freshness: The 55-day accelerated stress tests proved that Vitamin E Oil keeps the natural oils fresh. The sticks did not sweat, melt, separate, or lose their pleasant floral Kewra aroma over time.

FUTURE SCOPE

• Testing on Real People: The next important step is to conduct clinical trials on human volunteers with severe chapping to record exactly how many days it takes to completely cure cheilitis.
• Adding Natural Sun Protection: Future batches can incorporate mineral sunscreens like micro-fine Zinc Oxide or Titanium Dioxide to shield weak lip tissue from dangerous UV sunburns.
• Upgrading to Eco-Friendly Cases: To make the product completely zero-waste, future manufacturing can shift away from plastic tubes and use biodegradable, cardboard push-up packaging.
• Advanced Lab Analysis: Researchers can use high-tech machines like High-Performance Liquid Chromatography (HPLC) to track the exact lifespan and strength of the healing chemicals in Licorice and Tulsi over a two-year period.
• New Herbal Flavours: Future formulations can explore alternative, non-irritating natural flavors like real vanilla, strawberry extract, or sweet mint to give consumers more choices without triggering lip skin allergies.
