5-ETHYL-3-HYDROXY-4-METHYLFURAN-2-ONE.

Optional CAS 698-10-2 / PERFUMING

A multifunctional furanone compound that serves dual roles as a fragrance component and antioxidant agent in skincare formulations. Also known as Maple Furanone, this ingredient demonstrates protective properties against oxidative stress and glycation damage. Its unique maple-caramel scent profile makes it particularly valuable in gourmand-scented cosmetic products.

Summary

fragrance antioxidant anti-glycation agent

Science

Mechanism of Action

Functions through dual pathways: scavenges reactive oxygen species (ROS) to protect cellular structures, and inhibits methylglyoxal-induced cytotoxicity to prevent advanced glycation end-product formation. The anti-glycation activity helps preserve skin proteins like collagen and elastin from sugar-related damage, while its antioxidant properties neutralize free radicals that accelerate aging processes.

Dusting Analysis

Not commonly dusted

Primarily used as a fragrance component at very low concentrations due to high odor potency, making dusting unlikely and unnecessary
