PEG/PPG-6/2 GLYCERYL COCOATE.

Valuable CAS - / SURFACTANT - EMULSIFYING

PEG/PPG-6/2 Glyceryl Cocoate is a hydrophilic emollient and mild surfactant derived from coconut oil and glycerin. It functions as a versatile emulsifier and solubilizer, improving formulation stability and enhancing the sensory experience of skincare products.

Science

Mechanism of Action

This ingredient primarily functions as a surfactant and emulsifier, effectively reducing the interfacial tension between immiscible liquids like oil and water, thereby creating stable formulations. Beyond its emulsifying capabilities, it acts as a conditioning agent and emollient, contributing to skin softness and moisturization. Its humectant properties draw moisture to the skin, while its role as a solubilizer allows for the incorporation of lipophilic active ingredients, fragrances, and colorants into aqueous systems. As a PEG derivative, it can also subtly enhance the penetration of other ingredients.

Key findings

  1. 01 In personal cleansing compositions, concentrations up to 10% by weight significantly improve viscosity, enhance skin-feel characteristics (including softness and moisturization), and boost emulsification efficacy, while maintaining formula clarity in surfactant systems.

Dusting Analysis

Not commonly dusted

PEG/PPG-6/2 Glyceryl Cocoate is typically a liquid or waxy solid, not prone to 'dusting' as a fine particulate matter.

Stability

Optimal stability is observed within a pH range of 4.0 to 8.5, with a preferred range of 5.0 to 7.0 due to its susceptibility to hydrolysis under strong acid or strong alkali conditions. It can be cold-mixed, and gentle heating up to 40°C can facilitate incorporation. It is well-suited for aqueous systems and acidic shampoo formulations.

Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has deemed PEG glyceryl cocoates, including PEG/PPG-6/2 Glyceryl Cocoate, safe for use in rinse-off products and safe at concentrations up to 10% in leave-on products. This assessment was re-affirmed in 2014, with the previous 'damaged skin' caveat for some PEG esters being removed, indicating a broad safety profile for this class of ingredients when formulated appropriately to be non-irritating.
