GAMMA-DECALACTONE.

Optional CAS 706-14-9 / PERFUMING

Gamma-decalactone is an aromatic compound recognized for its intense peach-like, sweet, and fruity aroma, primarily serving as a perfuming agent. It also exhibits antimicrobial activity and is considered safe for cosmetic use at specified concentrations.

Summary

Perfuming Antimicrobial Agent

Science

Mechanism of Action

This lactone functions predominantly as a fragrance ingredient, imparting a distinct peach-like scent to formulations. While it possesses general antimicrobial properties, specific detailed mechanisms for direct skin benefits beyond its aroma and preservative potential are not extensively documented.

Key findings

  1. 01 Research has indicated that gamma-decalactone at concentrations between 2.5% and 10% demonstrates antimicrobial activity against various microbial species, including bacteria, yeasts, and molds. A 5% concentration was shown to completely inhibit the growth of Bacillus subtilis and Yarrowia lipolytica in pectin-based packaging films.

Transparency

Dusting Analysis

Not commonly dusted

Gamma-decalactone is primarily utilized as a perfuming agent. Although it has reported antimicrobial properties, there is no current evidence to suggest it is being over-marketed or 'dusted' with unproven claims for specific skin benefits beyond its established aromatic and potential preservative roles.

Sensitization risk Low

The Research Institute for Fragrance Materials (RIFM) Expert Panel has concluded gamma-decalactone is safe for cosmetic use, demonstrating no skin sensitization reactions at 10% in human maximization tests. It is not anticipated to cause phototoxicity or photoallergenicity. The FDA also considers it safe for food use. While a general Safety Data Sheet (SDS) may indicate potential irritation, RIFM's specific cosmetic assessment supports its low sensitization risk at typical use levels.

Our Assessment

Verdict

Optional

Primarily valued for its pleasant aromatic profile and generally recognized as safe for cosmetic applications, gamma-decalactone offers secondary antimicrobial properties, yet lacks extensive direct clinical efficacy data for targeted skin benefits.
