Why is Glyceryl Stearate SE an ideal choice for highly stable O/W emulsions?
Glyceryl Stearate SE is a self-emulsifying nonionic surfactant made by reacting glycerol with stearic acid, where "SE" stands for "Self-Emulsifying". This ingredient has both hydrophilic and lipophilic structures and is a classic oil-in-water (O/W)
Emulsifier. It appears as white to slightly yellow particles with good fluidity and is stable at room temperature, making it easy to store and prepare. It is soluble in ethanol, chloroform, and a variety of vegetable oils and synthetic oils. It is insoluble in water, but can be evenly dispersed under heating and stirring conditions.
Function in cosmetic formulations
Glyceryl Stearate SE is a typical
Emulsifier for cosmetics, commonly used in skin care products and medical creams, and can be used as both a primary emulsifier and a co-emulsifier. It can help form a delicate and stable emulsion structure in the formula, prevent oil-water separation, and improve the overall stability of the product. In addition, it can also give the lotion good consistency and ductility, making it smoother when applied and naturally skin-friendly. When compounded with high HLB emulsifiers (such as PEG-100 Stearate), its synergistic effect is particularly obvious, which can greatly improve the stability of the lotion in long-term storage or high temperature and high humidity environments.
Application range
This emulsifier is widely used in creams, lotions, sunscreens, cosmeceuticals and various formulas that need to improve stability and skin feel. It is mild in nature, not easy to irritate, suitable for sensitive skin, and can be applied to cold systems, which is conducive to retaining the effectiveness of active ingredients. The recommended addition amount is 1%-10%, and the usage ratio can be adjusted according to the product texture requirements. The product packaging is 25kg/bag.
