Goat Milk
What is Goat Milk?
Goat milk, sourced from the mammary glands of domestic goats (Capra hircus), is a nutrient-rich emulsion primarily composed of water, milk fats like triglycerides, proteins such as casein and whey, lactose, lactic acid, and various vitamins and minerals including A, B vitamins, calcium, and magnesium. In cosmetic formulations, it falls under skin conditioning agents and is commonly incorporated into moisturizers, cleansers, soaps, and lotions. It functions by forming a protective barrier through its emollient fats that lock in moisture, humectant properties from proteins and sugars that attract water to the skin, and mild exfoliating action from naturally occurring lactic acid, which supports smoother texture without harshness. This makes it a popular choice for gentle, everyday skincare products aimed at hydration and comfort.
