Ações bioquímicas/fisiológicas

Sodium dodecyl sulfate (SDS)/lauryl sulfate, an ionic detergent has the ability to distract biological membranes. It can block RNase and deoxyribonuclease (DNase) activity. SDS is one of the main constituents of several reagents, that are used to purify nucleic acids. It is also considered as a permeability enhancer in oral formulations.

Qualidade

Predominantly (approx. 70%) C12; lauryl sulfate, sodium salt; balance consists of higher homologs.
