PPG-8-DECETH-6.

Valuable CAS 68154-97-2 / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

PPG-8-DECETH-6 is a versatile synthetic polymer that functions as an emollient, emulsifier, and surfactant in cosmetic formulations. It is designed to enhance product stability and texture while providing direct benefits to the skin, such as improved hydration and barrier support.

Summary

Emulsifying Surfactant Emollient Skin Conditioning Cleansing Agent

Science

Mechanism of Action

This ingredient operates by forming a protective, occlusive barrier on the skin's surface, which effectively reduces transepidermal water loss, thereby boosting moisture retention and preventing dehydration. This action helps to maintain the skin's natural hydrolipidic balance and minimize irritation. In formulations, PPG-8-DECETH-6 acts as an emulsifier, ensuring the stable and homogeneous blending of immiscible oil and water phases, contributing to a desirable product consistency. Furthermore, its surfactant properties enable it to function as an effective cleansing agent.

Stability

PPG-8-DECETH-6 functions effectively as an emulsifier, stabilizing oil-in-water mixtures. Polypropylene glycols (PPGs), including related compounds like PPG-8, are generally water-soluble, particularly in colder temperatures, and are miscible with most organic solvents, excluding long-chain aliphatic hydrocarbons.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel concluded that PPG-8-DECETH-6, along with over 130 other alkyl PEG/PPG ethers, is safe for use in cosmetics when the final formulation is non-irritating. This assessment primarily relied on read-across data from analogous compounds due to limited individual ingredient data. The panel noted the large molecular weight of these polymers, which suggests a low likelihood of skin absorption. However, general concerns for ethoxylated ingredients, such as potential trace contamination with manufacturing by-products like ethylene oxide and 1,4-dioxane, have been highlighted by organizations such as EWG.
