Description

General description

A synthetic zwitterionic detergent, which unlike other amphoteric surfactants, retains its zwitterionic character over a broad pH range. This property is attributed to the presence of a strongly basic quaternary ammonium ion and an acidic sulfonate ion of equal strength. This ionic balance presumably prevents irreversible binding to either anionic or cationic compounds.

Warning

Toxicity: Irritant (B)

Reconstitution

Following reconstitution, aliquot and freeze (4°C). Stock solutions are stable for up to 1 month at 4°C.
