Product Category: Surfactants / Detergent Raw Materials
Chemical Name: Linear Alkylbenzene Sulphonic Acid
Alternative Names: LABSA / Sulphonic Acid / Acid Slurry
CAS Number: Common commercial reference 27176-87-0
Appearance: Brown viscous liquid
Active Matter: Approximately 96%
Product Overview
Sulphonic Acid, commonly supplied commercially as LABSA 96%, is one of the most important raw materials used in detergent manufacturing.
LABSA is an anionic surfactant intermediate that is normally neutralised during formulation to produce linear alkylbenzene sulphonate surfactants.
