Dodecyl benzene sulphonic acid (DBSA)
Technical grade
Dodecylbenzene Sulphonic Acid (DBSA or LABSA) is a widely used anionic surfactant and detergent intermediate. It is an organic acid derived from linear alkylbenzene (LAB) sulfonation, typically with a dodecyl (C12) alkyl chain, hence the name.
The sulphonic acid group provides strong negative charge → excellent cleaning, wetting, and foaming power. The linear dodecyl group provides compatibility with biodegradation, making LABSA more environmentally acceptable than older branched-chain versions.
