Now-a-days there has been a growing global shift toward the use of natural and herbal-based cosmetics, which is driven by rising consumer awareness of the potential adverse effects of synthetic skincare ingredients on both skin health and the environment. Consumers are increasingly seeking formulations that not only cleanse effectively but also deliver nourishment and rejuvenation via bioactive compounds derived from natural sources. Among such promising approaches, milk-based and fruit enzyme-based formulations have significant attention for their multifunctional benefits and biocompatibility [1]. Goat milk is one such ingredient, traditionally it is used in skincare and now receiving renewed research interest. It is rich in proteins, essential fatty acids, vitamins (A, B6, B12, E) and notably lactic acid, a mild alpha hydroxy acid (AHA) [2]. Lactic acid aids in the removal of dead skin cells, thereby facilitating smoother and brighter skin surfaces. Furthermore, goat milk’s lipid profile closely resembles that of human skin, and its pH is similar to that of the skin’s acid mantle, which makes it particularly suitable for sensitive and dry skin types. For cortico-dermatological and cosmetic uses, goat milk has used to support wound healing, tissue regeneration, sebum regulation, hydration, barrier repair and anti-inflammatory effects although much of the evidence remains preliminary [3]. Another ingredient is Papaya (Carica papaya), which is widely used for its skin-brightening, anti-inflammatory and exfoliating properties. The enzyme papain helps in the breakdown of inactive keratin and dead skin cell build-up; thus, it enhances the skin texture and tone Papaya is also rich in antioxidant vitamins such as A and C, which protect against oxidative stress and support skin renewal. The combination of goat milk and papaya therefore offers a promising synergy: gentle exfoliation and nourishment together in a mild formulation [5]. Conventional face washes often rely heavily on synthetic surfactants and chemical additives, which may strip the skin of its natural oils, disrupt the acid mantle, irritate sensitive skin and potentially lead to long-term barrier damage [6]. In contrast, a goat-milk and papaya-based face wash presents a skin-friendly, sustainable alternative: one that is rooted in naturally derived bioactive and designed for cleansing while maintaining skin health. Accordingly, the objective of this study is to formulate and evaluate a face wash incorporating goat milk and papaya extracts, with a focus on its physicochemical properties (pH, viscosity, foaming and spreadability), stability, cleansing efficacy and skin compatibility. The findings are intended to contribute to the growing field of natural cosmetic formulations and support the utilization of locally available bioactive raw materials in skincare product development [7].
MATERIALS AND METHODS
MATERIALS
Fresh goat milk was procured from a certified local dairy source. Ripe Carica papaya fruits were obtained from a local market and authenticated by the department of Pharmacognosy of Rupesh Badhan institute of pharmacy. The other excipients used in the formulation, sodium coccyl -iso-ethionate as a surfactant, turmeric powder as an anti-inflammatory and brightening agent, glycerin as a humectant, honey as a moisturizer and antibacterial, leucidal as a preservative and lavender oil for fragrance. All reagents and chemicals used were of analytical grade and procured from recognized suppliers [8].
