PEG/PPG-120/10 TRIMETHYLOLPROPANE TRIOLEATE.

Valuable CAS - / VISCOSITY CONTROLLING

PEG/PPG-120/10 TRIMETHYLOLPROPANE TRIOLEATE is a sophisticated polymer primarily utilized in cosmetic formulations as a potent rheology modifier and thickening agent. It effectively controls product viscosity and also functions as an emulsifier, contributing to formulation stability. In hair care, it further acts as a conditioning booster, enhancing sensorial performance.

Summary

Viscosity Controlling Thickening Rheology Modifying Emulsifying Conditioning (Hair)

Science

Mechanism of Action

This ingredient operates by influencing the rheological characteristics of cosmetic preparations, predominantly serving to control viscosity and provide thickening effects. It exhibits particular efficacy within surfactant systems that are low in or entirely free of ethersulfates. Its emulsifying properties are derived from a unique combination of micellar and associative thickening mechanisms. Beyond its textural contributions, in hair care applications, it functions as a conditioning agent, noticeably improving wet combing and overall sensory feel as a potential alternative to silicones.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that alkyl PEG/PPG ethers, including this specific ingredient, are safe under current cosmetic use and concentration practices, provided formulations are non-irritating. The panel noted its larger molecular size reduces skin penetration and typically lower usage concentrations compared to related ingredients. Concerns regarding potential impurities such as ethylene oxide, propylene oxide, or 1,4-dioxane were evaluated and addressed. A NICNAS report for a blend containing this ingredient also indicated 'No Significant Concern' to public health and 'low toxicity and irritancy' for workers. It is worth noting that some environmental organizations classify PEGs and PPGs as 'sceptical microplastic' ingredients, whose environmental impact regarding solubility, toxicity, persistence, and bio-accumulation may vary with chain length and requires further investigation.
