Gamma Dodecalactone FCC N° 455
Premium Synthetic Ingredient for Perfumery
Gamma-Dodecalactone (γ-Dodecalactone) is a synthetic lactone widely recognized for its sweet, fatty, and waxy fruit character, enriched by a subtle green rind undertone. With a high degree of purity (>97%) and robust olfactory tenacity, it plays a pivotal role in perfumery for imparting warm, creamy depth to fruity, floral, and gourmand compositions. This molecule is frequently used to add roundness and diffusion, serving both as a top-to-heart note modifier and as a secondary base material in lactonic and tropical fragrance structures.

What is Gamma-Dodecalactone?
Gamma-Dodecalactone is a member of the lactone chemical class, specifically a γ-lactone featuring a 12-carbon chain. Lactones are cyclic esters that commonly occur in nature as part of fruit and dairy aromas. This particular compound is not found in significant quantities in natural essential oils but is widely produced synthetically for fragrance and flavor applications.
In perfumery, γ-Dodecalactone is prized for its fatty-cream sweetness, which recalls ripe peach, coconut flesh, or milked tropical fruit. Unlike shorter-chain lactones that may veer toward coconut or dairy notes, this molecule leans more waxy and refined, with a green peel edge that helps balance and naturalize sweetness in a blend.
Olfactory Profile and Perfumery Applications
Gamma-Dodecalactone is commonly used to:
Round off fruity and tropical accords, especially peach, apricot, mango, and lychee
Add creaminess to florals, such as tuberose, jasmine, frangipani, or ylang-ylang
Contribute lactonic facets in gourmand and dessert-style perfumes
Soften sharp aldehydic or ozonic profiles with warm diffusion
Balance sugar-sweet top notes with waxy-green realism
Its medium strength and notable tenacity make it appropriate across:
Fine fragrances
Cosmetic body care
Candles and wax-based products (thermal stability permitting)
Regulatory and Safety Overview
IFRA Status — Not restricted; safe for use within standard concentrations
EU Allergen Declaration — Not listed among the 26 declarable fragrance allergens
FEMA GRAS — Listed as FEMA 2400; Generally Recognized As Safe for flavor use
REACH — Registered under standard synthetic ingredient listings
Storage Conditions — Stable under normal conditions; store in a cool, dry area away from light
Use Concentrations —
Fine fragrance: typically 0.05–1%
Body care: 0.01–0.5%
Candles: up to 1%, depending on wax compatibility
✅ Regarded as safe and non-sensitizing in both perfumery and flavor contexts.
Additional Notes
Gamma-Dodecalactone is often blended with:
Gamma-Undecalactone (Peach Lactone) for increased realism
Heliotropine and Coumarin in dessert-inspired bases
Tiare, Coconut, and Vanilla materials in tropical summer themes
Green tea or fig accords to contrast sweetness with vegetal depth
Its profile plays an essential role in "peach skin" impressions and soft skin lactonic notes, making it ideal for cosmetic-style perfumery and milk-based fantasy accords.
