CAS 9011-21-6

PEG glyceryl stearate

Description:

PEG glyceryl stearate, with the CAS number 9011-21-6, is a non-ionic surfactant and emulsifier commonly used in cosmetic and pharmaceutical formulations. It is derived from the esterification of glycerol and stearic acid, followed by ethoxylation, which introduces polyethylene glycol (PEG) chains into the structure. This compound is characterized by its ability to stabilize emulsions, enhance the texture of creams and lotions, and improve the spreadability of products on the skin. PEG glyceryl stearate is typically a white to off-white waxy solid or a viscous liquid, depending on its molecular weight and formulation. It is soluble in water and oils, making it versatile for various applications. Additionally, it is known for its mildness and compatibility with a wide range of ingredients, which makes it suitable for sensitive skin formulations. Its safety profile is generally favorable, with low irritation potential, although it is always advisable to conduct patch tests for individual sensitivities.
