How we scored it
Where it comes from
Stearic acid, typically from palm oil or tallow, is diesterified onto diethylene glycol (two ethylene-oxide units) made from petrochemical ethylene. The two large fatty chains dominate the mass.
In plain English
An emulsifier that helps blend oil and water in creams. It pairs two stearic acid molecules, from vegetable oil or tallow, with a small lab-made glycol linker.
