Polyglycerol-3 diisostearate is a highly effective water-in-oil
Emulsifier derived from plant raw materials. It is formed by the esterification reaction of polyglycerol backbone and branched isostearic acid, and its appearance is a yellow liquid. Its excellent amphiphilicity enables it to construct a stable water-in-oil emulsion in a high oil phase formula. The packaging specifications are 25kg and 190kg barrels, which are suitable for customized processing scenarios.
General characteristics
As a water-in-oil emulsifier, it has good compatibility and can coexist harmoniously with a variety of oils, waxes, UV filters and colorants without causing system turbidity or stratification. The typical addition amount is 1–5%, within which it can fully play the role of emulsification assistance without negatively affecting the skin feel of the product. Its non-ionic properties make it low in irritation and safe to use even in sensitive skin or baby care formulas. It has good chemical stability and can maintain stable efficacy over a wide temperature and pH range.
Role in cosmetics
In cosmetic formulas, it has various and practical functions: in addition to assisting emulsification, it can significantly improve the ductility of the product, making it smoother and easier to apply creams, primers, etc.; it can enhance the stability of the formula and extend the shelf life of the product, especially suitable for products with high stability requirements such as sunscreens and water-free makeup. In sunscreen products, it can help UV filters to disperse evenly and improve the sunscreen effect; in baby ointments and moisturizing products for dry or sensitive skin, it can lock in moisture and reduce external irritation. It is widely used in a variety of personal care products such as creams, primers, and colored sunscreens, and is an ideal raw material that takes into account both mildness and functionality.
