Gaubert A, Jame P, Bordes C, Clément Y, Guibert S, Batteau M, Lomberget T, Anchisi A, Lantéri P, Casabianca H.
PMID: 27060838
Rapid Commun Mass Spectrom. 2016 May 15;30(9):1108-14. doi: 10.1002/rcm.7537.

RATIONALE: To develop more eco-friendly laundry detergents, renewable surfactants synthesized from vegetal sources are increasingly being used. In a more stringent regulation context, the determination of bio-sourced surfactant origin thus appears essential to assess the claims of detergent manufacturers....
