Polyglyceryl-4 Oleate is a non-ionic surfactant of the polyhydroxy ester class, which has both hydrophilic and oleophilic properties. Its molecular structure contains multiple hydrophilic hydroxyl groups, which makes it exhibit superior emulsification, dispersion, and stability performance between water and oil. By adjusting its polymerization degree, fatty acid type, and esterification degree, polyglycerol oleate can obtain different HLB values to meet various special application requirements in areas such as Cosmetics & Personal Care. This colorless, odorless, and non-hydrolyzable compound is widely used in various fields like food, daily chemical, petroleum, textile, and more. Specifically in Cosmetics & Personal Care, it is used as an Emulsifying Agent, viscosity regulator, crystallization regulator, and quality improver. Its stability and emulsifying performance are superior, which can significantly improve the texture and taste of products, and has antibacterial effects, helping to extend the shelf life of products. It is worth noting that while it is not a direct Plant Extract, its compatibility and effectiveness with such extracts make it a valuable addition to formulations containing plant-based ingredients.
