Chemistry Thursday: Polyunsaturated fatty acids – alpha-linolenic, gamma-linolenic, punicic, and stearidonic acids (C18:3 – C18:4), part 27

by

Welcome back to this introduction to cosmetic chemistry series! I hope you’re enjoying it so far. I know I am! Let’s talk more about carboxylic acids, specifically the fatty acids we encounter over and over again in our liquid oils, solid oils, butters, and waxes. This week, we’re getting into polyunsaturated C18:3, and C18:4 fatty...

Polyphenols: Hydroxybenzoic acids – benzoic acid, hydroxybenzoic acid, gallic acid (Updated 2025)

by

Hydroxybenzoic acids are polyphenols we find in our oils. They have the benzene ring with an acid – COOH – on the end, making them carboxylic acids. They offer all kinds of properties to our formulas – as you’ll see in a minute – and most work as anti-oxidants to slow down rancidity of oils....
