Glyceryl Stearate
Glyceryl Stearate is a substance that occurs naturally in the human body and can also be derived from animals, though most Glyceryl Stearate used in cosmetics is either plant-derived (e.g., from olive oil or coconut) or synthetically produced. In its raw form, it appears as a white or cream-colored wax-like solid. This ingredient functions as an emollient, surfactant, and emulsifier in skincare products. It is considered safe within typical usage levels of 1–10%.

Effects in Cosmetics
Glyceryl Stearate offers several effects and applications in cosmetics, including:
Acting as an emollient, it helps to make the skin smooth and soft.
Its emulsifying properties are versatile, allowing it to be a valuable addition to various types of emulsions (oil-in-water or water-in-oil), supporting the efficacy of skin-replenishing ingredients like ceramides and fatty acids.
Its moisturizing properties assist in making the skin appear and feel softer and smoother.
It also creates a barrier on the skin, helping to prevent water loss.
