Common Name(s): Lauryl pyrrolidone carboxylic acid,anti-odour conditioning
CAS Number: 31105-03-0
DESCRIPTION
What It Does: Provides combined antibacterial deodorant and nmf conditioning from lauryl pca.
Why It's Used: Conditioning deodorant — lauryl pca's unique combination of cationic antimicrobial deodorant activity and nmf-derivative conditioning provides deodorant function with skin-friendly conditioning simultaneously.
How It Works: Lauryl ammonium pca: cationic quaternary ammonium antimicrobial vs odour bacteria. pca (pyrrolidone carboxylic acid) moiety provides nmf-type skin conditioning. dual antimicrobial+conditioning from single molecule. gentle compared to benzalkonium chloride.

SCIENTIFIC NOTE
Lauryl pca's dual deodorant+conditioning from a single molecule demonstrates the cosmetic chemistry strategy of combining an antimicrobial fatty chain (lauryl = c12) with a skin-conditioning acid salt (pca = nmf component) — the same c12 chain that provides antimicrobial activity in lauryl glucoside and sodium lauryl sulfate here provides antimicrobial deodorant function alongside pca conditioning.
