SWEET ALMOND OIL PEG-8 ESTERS.

Valuable CAS - / SKIN CONDITIONING - EMOLLIENT, SURFACTANT - EMULSIFYING

Sweet Almond Oil PEG-8 Esters is a hydrophilic derivative of sweet almond oil, designed to act as a versatile skin conditioning agent and emulsifier. It significantly contributes to improving skin hydration, elasticity, and overall texture while ensuring the stability of complex skincare formulations.

Summary

emollient emulsifying skin conditioning surfactant

Science

Mechanism of Action

This ingredient functions by reducing flakiness and restoring suppleness to dry or damaged skin through its conditioning properties. As a surfactant and emulsifying agent, it effectively lowers the interfacial tension between immiscible oil and water phases, enabling the creation and stability of uniform emulsions. Furthermore, it imparts emollient benefits, softening and smoothing the skin's surface.

Stability

The base Sweet Almond Oil component is susceptible to oxidation, leading to potential rancidity and an increase in acid value; this process is accelerated by elevated temperatures. The inclusion of antioxidants, such as propyl gallate, can substantially enhance its stability and extend shelf-life. The PEG-8 portion exhibits broad miscibility with water, alcohols, esters, ketones, aromatic solvents, and chlorinated hydrocarbons, but is immiscible with alkanes, paraffins, waxes, and ethers.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel concluded that PEGylated oils, including Sweet Almond Oil PEG-8 Esters, are safe for use in cosmetics when formulated to be non-irritating. Concerns exist regarding potential residual levels of ethylene oxide and 1,4-dioxane, both classified as carcinogenic, which may arise from the ethoxylation process. The ultimate safety is contingent upon the purity of the obtained compound, a detail not always provided by manufacturers. PEG-8, a constituent of this ingredient, is approved by the FDA and CIR for general use, though its application on broken skin is not recommended.
