METHYL BETA-NAPHTHYL ETHER.

Questionable CAS 93-04-9 / PERFUMING

Methyl Beta-Naphthyl Ether is an aromatic compound primarily valued for its sweet, orange-blossom, and acacia-like fragrance. While widely employed in the aroma industry, current research does not extensively detail direct therapeutic or cosmetic benefits for the skin beyond its scent profile.

Science

This compound functions predominantly as a fragrance agent, imparting a characteristic sweet, floral aroma to formulations. Information regarding a specific mechanism of action on the skin for direct therapeutic or cosmetic benefits is currently limited, although some historical references allude to potential anti-inflammatory properties without detailing their cutaneous application or mechanism.

Sensitization risk Low

The Research Institute for Fragrance Materials (RIFM) is currently conducting a comprehensive safety assessment. Read-across data from a similar β-naphthyl ether analog suggests non-clastogenicity in vitro and an adequate margin of exposure for repeated dose toxicity. The FDA has deemed it safe for use as a flavoring agent in food at specific, limited concentrations.
