PEG-7 Trimethylolpropane Coconut Ether ●
TL;DR. This ingredient is a nonionic solubilizer and mild surfactant, helping disperse oils, scent materials, and oily soils into water-based formulas. It can also add an emollient, re-fatting feel in cleansers.
What does PEG-7 Trimethylolpropane Coconut Ether do in a cosmetic formula?
This ingredient is a nonionic solubilizer and mild surfactant, helping disperse oils, scent materials, and oily soils into water-based formulas. It can also add an emollient, re-fatting feel in cleansers.
Is PEG-7 Trimethylolpropane Coconut Ether clean?
From a clean-beauty lens, it has friction because it is ethoxylated and can carry trace manufacturing residuals such as 1,4-dioxane if purification is poor. It is generally mild in use, but many stricter lists flag this class for processing rather than routine skin irritation.
Is PEG-7 Trimethylolpropane Coconut Ether sustainable?
It is made from a blend of it-derived fatty chains and petrochemical-derived polyether units. Biodegradability is less straightforward than simple plant oils or sugars, and the synthetic water-soluble portion weakens its Green Chemistry profile.
Is PEG-7 Trimethylolpropane Coconut Ether COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic because ethoxylated materials are outside the standard. It has partial bio-based content, but the petrochemical reactive step and residual-control burden make it a poor fit with Green Chemistry preferences.
How does PEG-7 Trimethylolpropane Coconut Ether work chemically?
The molecule is a tri-functional polyether built on a three-armed alcohol core, capped with it fatty it chains and an average of seven oxyethylene units, giving it amphiphilic, nonionic behavior. It is usually used at low single-digit levels as a solubilizer or secondary cleanser, is stable across common cosmetic pH ranges, and pairs with anionic or amphoteric surfactants to improve clarity and oil dispersion.
