Glycine Soja (Soybean) Milk
What is Glycine Soja (Soybean) Milk?
Soy Milk is a liquid emulsion derived from soybeans (Glycine max), rich in proteins, isoflavones, vitamins (such as B vitamins), and minerals like potassium and magnesium. In skincare, it is used for its emollient, antioxidant, and soothing properties, often incorporated into cleansers, moisturizers, and masks to hydrate and calm the skin. It contains natural enzymes and compounds that may help brighten complexion and reduce signs of irritation.
Roles in Formulation
This ingredient serves the following purposes in cosmetic formulations:
Emollient
Softens and smooths skin by filling in surface roughness and improving slip; can also help reduce moisture loss when paired with occlusives and film formers.
Skin protecting
Forms a barrier to protect skin from external irritants.
Humectant
Attracts and holds water in the stratum corneum, boosting hydration and plumpness; commonly used in moisturizers, cleansers, and hair conditioners.
Skin conditioning agent
Maintains skin softness, smoothness, and flexibility.
Soothing
Helps reduce the feeling of discomfort and visible irritation by supporting skin calmness, often through anti-irritant, barrier-supporting, or cooling mechanisms.
Antioxidant
Slows oxidation of oils, fragrances, and sensitive actives to improve shelf life and reduce rancidity or color change; sometimes also supports skin protection from oxidative stress.
