PPG-2 C12-15 PARETH-6.

Valuable / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

PPG-2 C12-15 PARETH-6 is a sophisticated ethoxylated fatty alcohol derivative, serving primarily as a surfactant, emulsifier, and cleansing agent in skincare formulations. It is designed to reduce surface tension and stabilize complex oil-in-water or water-in-oil mixtures, enhancing product consistency and distribution.

Summary

emulsifying surfactant cleansing agent

Science

Mechanism of Action

This ingredient functions by significantly lowering the surface tension within cosmetic preparations, which promotes the uniform spreading and distribution of products on the skin. As an emulsifier, it plays a crucial role in stabilizing formulations that combine immiscible liquids like oil and water. By modifying the interfacial tension between these phases, it facilitates the dissolution of oily or greasy components within the water phase and maintains the stability of emulsions found in creams and lotions.

Stability

Based on research into analogous alkoxylated fatty alcohols, such as C12-15 Pareth-11, this ingredient demonstrates broad pH stability. A 1% aqueous solution typically maintains a pH range of 5.0-7.0. It is stable across acidic, neutral, and diluted alkaline environments, exhibiting resilience even against strong bases like sodium hydroxide.

Safety

Safety Profile

CIR Status
Safe as used with restrictions
Sensitization risk Moderate

The Cosmetic Ingredient Review (CIR) Expert Panel concluded that PPG-2 C12-15 PARETH-6, along with 130 other alkyl PEG/PPG ethers, is safe under current cosmetic practices and concentrations, provided the final formulation is non-irritating. This assessment largely relied on data from analogous compounds due to limited specific individual data. The panel acknowledged that these large molecules are less likely to penetrate the skin and enter systemic circulation. However, potential concerns include residual starting materials (ethylene oxide, propylene oxide), the by-product 1,4-dioxane, and the possibility of these ingredients acting as penetration enhancers for other substances.
