How we scored it
Where it comes from
PEG-5 Stearate is stearic acid esterified with polyethylene glycol averaging 5 ethylene-oxide units from petrochemical feedstock. The supplied formula appears to describe a 1-EO analogue rather than the stated 5-EO product.
In plain English
An emulsifying wax made from stearic acid, a natural fatty acid, combined with a short synthetic glycol chain. About half its weight comes from natural fat, half from petrochemical feedstock.
