Carboxylic Acids in Cosmetic Chemistry: Function, Reactivity, and Formulation Control

Carboxylic acids are one of the most functionally diverse groups in cosmetic chemistry. They can exfoliate, preserve, adjust pH, stabilize emulsions, and even structure entire formulations. But with that versatility comes complexity—especially regarding pH, irritation potential, and compatibility.

Mastering carboxylic acids means understanding both their chemistry and their behavior in real formulations.
