POLYGLYCERYL-4 OLEATE ●
TL;DR. This ingredient is a nonionic emulsifier and co-surfactant, especially useful in cleansing oils, balms, and water-in-oil or low-foam systems. It helps oil and water phases mix, improves rinse-off, and can support pigment or oil dispersion.
What does POLYGLYCERYL-4 OLEATE do in a cosmetic formula?
This ingredient is a nonionic emulsifier and co-surfactant, especially useful in cleansing oils, balms, and water-in-oil or low-foam systems. It helps oil and water phases mix, improves rinse-off, and can support pigment or oil dispersion.
Is POLYGLYCERYL-4 OLEATE clean?
From a clean-beauty perspective, it is generally well accepted because it is mild, non-ethoxylated, and not commonly associated with restricted-list concerns. Sensitivity is uncommon, though finished-formula tolerance still depends on level, purity, and the surrounding surfactant system.
Is POLYGLYCERYL-4 OLEATE sustainable?
This material is commonly made from glycerin and vegetable fatty-acid feedstocks, so sourcing can be renewable when suppliers document plant origin. It is expected to be readily biodegradable, with the main supply-chain question being traceability of the vegetable oil source.
Is POLYGLYCERYL-4 OLEATE COSMOS-approved?
It can be used in COSMOS-natural and COSMOS-organic formulas when made from permitted feedstocks and compliant processing. Its profile fits Green Chemistry well because it can use renewable raw materials, is non-ethoxylated, and is designed for biodegradability.
How does POLYGLYCERYL-4 OLEATE work chemically?
The molecule is a nonionic ester family with a short glycerin-derived polar head and a C18:1 fatty chain, giving it amphiphilic but oil-leaning behavior. Typical use is about 1 to 10% depending on whether it is serving as a co-emulsifier, dispersant, or rinse-off aid, and it is generally stable across the mildly acidic to neutral pH range used in skin and hair care.
