• Sodium dodecyl sulfate | C12H25NaO4S PubChem

    Sodium dodecyl sulfate (SDS), an anionic surfactant, is a common ingredient of cosmetic and personal care products. SDS is "readily biodegradable" with low toxicity and "is of no concern with respect to human health". Up to 1 g of SDS/kg is the maximum safe dose for children. Alkyl sulfates, including SDS, are microbicidal against HIV types 1 ...
