Question

addition of benzolkonium chloride with sodium lauryl sulfate​

Answer 1

Answer:

When benzalkonium chloride (BKC), a cationic surfactant, is added to sodium dodecyl sulfate (SDS), an anionic surfactant, and used in patch testing, on the basis of their known physicochemical interaction, it is possible to predict that there will be a tendency towards a reduction in the expected irritant response when when applied after the SDS exposure. 54 non-atopic adult volunteers were recruited for the study.
