2-ISOPROPYL-5-METHYLANISOLE.

Optional CAS 1076-56-8 / PERFUMING

Also known as Thymol Methyl Ether, this naturally-derived aromatic compound from thyme and basil essential oils serves primarily as a fragrance component in skincare formulations. While exhibiting promising antioxidant properties in laboratory studies, its primary cosmetic function remains sensory enhancement through perfuming and odor masking. This oil-soluble ingredient requires careful formulation due to its volatile nature and moderate irritation potential.

Summary

Perfuming Masking Potential antioxidant

Science

Mechanism of Action

Functions through its lipophilic structure, allowing integration into microbial cell membranes where it disrupts phospholipid bilayers and increases membrane permeability. Demonstrates antioxidant activity by scavenging free radicals and potentially inhibiting lipid peroxidation processes. In cosmetic applications, primarily provides sensory benefits through fragrance modification rather than direct skin therapeutic effects.
