Product Overview

Laurocapram (CAS 59227-89-3), commonly known as Azone, is a widely used transdermal penetration enhancer that improves the absorption of both hydrophilic and lipophilic active ingredients through the skin. It works by disrupting the ordered lipid bilayer structure in the stratum corneum, temporarily increasing intercellular lipid fluidity and reducing skin barrier resistance . With assay ≥99% (pharma grade) / ≥98% (cosmetic grade), it is suitable for topical pharmaceutical formulations, cosmetic actives delivery, and agrochemical adjuvants.
