Common Name(s): Ozonized oleic acid,ozonized oleic acid,oleic acid ozonide,controlled-release antimicrobial
CAS Number: N/a
DESCRIPTION
What It Does: Provides controlled-release ros generation from ozonide ring decomposition for broad-spectrum antimicrobial activity against bacteria, fungi, and viruses, with skin barrier repair from the oleic acid backbone.
Why It's Used: Ozonized oleic acid is selected for its dual antimicrobial and barrier-repair activity โ the ozonide rings provide a sustained ros antimicrobial mechanism that standard preservatives cannot replicate, while the oleic acid backbone simultaneously provides sc barrier repair emolliency.
How It Works: Ozonide ring thermolysis: 1,2,4-trioxolane โ singlet ยนoโ + aldehydes โ cell membrane lipid peroxidation in bacteria/fungi โ antimicrobial; oleic acid backbone โ sc lipid bilayer emollient integration.
