PEG-10 SUNFLOWER GLYCERIDES.

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

PEG-10 Sunflower Glycerides is a hydrophilic, water-dispersible emollient derived from high oleic sunflower oil, engineered to enhance skin conditioning and texture. It effectively integrates the nourishing properties of sunflower oil into aqueous formulations, leaving the skin feeling distinctly smooth and soft. Beyond emolliency, it also functions as an emulsifier and secondary surfactant.

Summary

emollient emulsifying surfactant skin-conditioning agent fragrance solubilizer

Science

Mechanism of Action

This ingredient operates by leveraging ethoxylated high oleic sunflower oil glycerides to impart a significant emollient effect. As a polyethylene glycol (PEG) derivative, its hydrophilic nature allows it to attract and bind water molecules through hydrogen bonding, thereby delivering gradual hydration and helping to mitigate transepidermal water loss by forming a protective film. It also stabilizes oil-in-water mixtures as an emulsifier and assists in cleansing and fragrance dispersion through its secondary surfactant capabilities.

Stability

As a hydrophilic, water-dispersible liquid, PEG-10 Sunflower Glycerides is stable within a neutral pH range, with a 10% solution exhibiting a pH between 5.0 and 7.0. Its properties make it particularly suitable for clear aqueous products and micro-emulsions. Viscosity in cleansing formulations, such as shampoos, can be effectively managed by adjusting salt concentrations.

Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel concluded that PEGylated alkyl glycerides, including PEG-10 Sunflower Glycerides, are safe for use in cosmetics when properly formulated to be non-irritating. For similar PEG glyceryl cocoates, the CIR Panel deemed them safe at concentrations up to 10% in leave-on products. While general concerns exist regarding 1,4-dioxane, a potential byproduct of ethoxylation, the ingredient itself is considered safe for cosmetic application under these specified conditions. It is also recognized as safe for specific food uses by the US FDA.
