Valuable CAS 180254-52-8 / 186511-05-7 / SKIN CONDITIONING - EMOLLIENT, SURFACTANT - EMULSIFYING

PEG-7 Sunflower Glycerides is a multi-functional PEGylated ester derived from sunflower oil. It acts as an effective skin conditioning agent, emollient, and a key formulant for blending oil and water phases, offering broad utility in skincare products.

Summary

Emollient Emulsifying Surfactant/Cleansing Skin Conditioning Agent Solubilizer

Science

Mechanism of Action

This ingredient works on skin primarily as an emollient, helping to restore the skin's natural barrier, enhancing moisture retention, and contributing to a soft, smooth feel through the formation of a semi-permeable protective film. As a surfactant, it facilitates gentle cleansing by assisting in the emulsification and removal of surface oils and impurities. Furthermore, it functions as an emulsifier to stabilize product formulations and ensures uniform distribution of ingredients, while also acting as a solubilizer for oil-soluble components in water-based systems.

Safety

Safety Profile

CIR Status
Safe as used
Max tested
11.3%
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel concluded that PEGylated alkyl glycerides, including PEG-7 Sunflower Glycerides, are safe for cosmetic application when formulated to be non-irritating. The maximum concentration of 11.3% cited refers to PEG-7 Glyceryl Cocoate, a closely related ingredient within the same evaluated family, as PEG-7 Sunflower Glycerides was not widely reported in use at the time of the assessment. There is a potential for trace 1,4-dioxane contamination during manufacturing via ethoxylation, a concern that can be effectively managed through standard purification processes.
