PPG-9 GLYCERYL ETHER.

Valuable CAS 25791-96-2 / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

PPG-9 Glyceryl Ether is a versatile polyglycol derivative primarily recognized for its skin conditioning properties. It effectively enhances skin texture, promoting a softer and smoother feel while also acting as a humectant to bolster skin hydration and mitigate dryness.

Summary

Skin Conditioning Moisturizing Emulsifying Surfactant Cleansing Solubilizer Solvent Foaming Agent

Science

Mechanism of Action

This ingredient functions by forming a protective layer on the skin's surface, which helps to maintain its optimal condition, improving both appearance and tactile smoothness. Its moisturizing capabilities prevent transepidermal water loss, thus combating dryness and flakiness. Beyond direct skin benefits, PPG-9 Glyceryl Ether serves as an excellent solubilizer and solvent, aiding in the dispersion of challenging components within formulations. As a surfactant, it facilitates cleansing, stabilizes emulsions by blending oil and water phases, and contributes to the foaming characteristics of products.

Stability

PPG-9 Glyceryl Ether is a water-soluble, non-greasy substance that readily integrates into aqueous formulations. It demonstrates efficacy as a solubilizer, solvent, and emulsifier, contributing to stable and homogenous product mixtures. Specific optimal pH ranges for stability were not identified, but it is critical to formulate products to avoid potential irritation.

Safety

Safety Profile

CIR Status
Safe as used with restrictions
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel deemed polypropylene glycols (PPGs) equal to or greater than 3, including PPG-9, as safe for cosmetic use provided they are formulated to be non-irritating. A broader assessment of related alkyl PEG/PPG ethers also supports safety when properly formulated to prevent irritation. While concerns about residues like ethylene oxide and 1,4-dioxane apply to some ethoxylated compounds, PPG-9 Glyceryl Ether is propoxylated (derived from propylene oxide and glycerin), which may present different residue implications; however, general purity remains paramount for all alkoxylated ingredients.
