PPG-2-ISODECETH-8.

Valuable CAS 155683-77-5 / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

PPG-2-ISODECETH-8 is an ethoxylated ether derived from isodecyl alcohol, serving as a multifunctional ingredient in skincare. It primarily acts as a surfactant and emulsifier, helping to stabilize formulations and facilitate the blending of oil and water-based components. Additionally, it functions as a cleansing agent, aiding in the effective removal of impurities from the skin.

Surfactant Emulsifying Cleansing Solubilizer Solvent Emollient (related compounds)

Science

Mechanism of Action

This ingredient operates by significantly reducing the interfacial tension between immiscible liquids, thereby enabling the formation and stabilization of emulsions within cosmetic formulations. As a cleansing agent, PPG-2-ISODECETH-8 lowers the surface tension of the stratum corneum, which assists in the detachment and removal of dirt and other impurities from the skin's surface. It also serves as a solubilizer and solvent for other ingredients, and related polypropylene glycol derivatives have been observed to possess emollient properties, which help form a protective layer to retain moisture and enhance skin suppleness.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Panel has assessed alkyl PEG/PPG ethers, including PPG-2-ISODECETH-8, and concluded they are safe for use in cosmetic products when formulated to be non-irritating. The panel noted that these are larger molecules, suggesting a reduced likelihood of skin penetration. Concerns regarding potential residual starting materials (ethylene oxide, propylene oxide) and the by-product 1,4-dioxane, along with their potential to enhance penetration, were evaluated and addressed by the CIR.
