Gamma-Undecalactone — CAS 104-67-6
Gamma-Undecalactone — CAS 104-67-6
Gamma-undecalactone (CAS 104-67-6), also known commercially as peach aldehyde or aldehyde C-14 (a historical trade name, not a chemical descriptor), is a naturally occurring lactone aroma compound widely used as a flavoring ingredient and fragrance component across food, beverage, and personal care sectors. UAB An Group Export supplies it in food and fragrance grades, matched to each customer's formulation and application requirements.
It is characterized by a rich, fatty, peachy aroma with waxy, fruity, and slightly coconut-like facets — sitting between the more diffusive, intensely fruity character of gamma-decalactone and the creamier, coconut-forward profile of gamma-dodecalactone in the peach lactone series. Its broad regulatory approval across major markets and natural occurrence in peaches, apricots, and other fruits make it a versatile core ingredient in both food flavoring and fine fragrance applications.
For industrial buyers, supply is coordinated around grade, purity, volume, packaging, and delivery destination, in line with applicable product and food-safety regulations. Bulk and commercial orders are both handled — send your requirements and we'll prepare a quote covering supply, packaging, logistics, and delivery.
The Peach Lactone Series — Positioning Gamma-Undecalactone
UAB An Group Export supplies the full gamma-lactone series used in peach and stone-fruit flavor and fragrance formulation. Gamma-decalactone (C10, CAS 706-14-9) delivers powerful, diffusive, true peach character with high impact at low usage levels. Gamma-undecalactone (C11, CAS 104-67-6) contributes a rich, fatty, waxy peach note with greater body and tenacity than the C10. Gamma-dodecalactone (C12, CAS 2305-05-7) adds creamy, coconut-like depth and longevity to the overall peach profile. Professional flavor and fragrance formulators routinely blend across the series to achieve naturalistic, multi-dimensional stone-fruit compositions — contact us to discuss supply of single grades or combinations matched to your formulation brief.
Key Applications
Food & Beverage FlavoringUsed in peach, apricot, nectarine, and tropical fruit flavor compositions for confectionery, dairy, beverages, baked goods, and fruit preparations. FEMA GRAS listed (FEMA 2781) and permitted under EU flavoring regulations. Its fatty, waxy peach character adds body and naturalism to fruit flavor profiles.
Fine Fragrance & PerfumeryUsed as a lactonic peach note in fine fragrance composition, contributing fatty, fruity, and waxy facets to fruity, floral, chypre, and gourmand fragrance structures. Valued for its tenacity and substantivity relative to the lighter C10 lactone.
Functional FragranceUsed in household and personal care product fragrancing where rich, fruity, and peach-like notes are required with good longevity.
Personal Care & CosmeticsUsed as a fragrance ingredient in cosmetic and personal care product formulations.
Flavor CompoundingUsed as a supporting or primary raw material in peach, stone fruit, and tropical flavor compound production, frequently combined with gamma-decalactone and gamma-dodecalactone for fuller profiles.
