Delta Dodecalactone
SYNTHETIC INGREDIENT FOR PERFUMERY
Delta Dodecalactone is a fruity-scented compound with a medium odor strength. It emits a fresh-fruity and oily aroma with strong staying power. Compared to gamma-Dodecalactone, it offers a more pronounced fruity essence and lacks a musky undertone.
This versatile lactone finds applications in aldehydic perfumes, heavy florals like gardenia and tuberose, and emerging fragrances. It's also utilized sparingly in flavor compositions to replicate butter and pear notes, as well as in diverse fruit formulations.

Information on δ-Decalactone
Description and Characteristics
δ-Decalactone has an oily peach odor and taste, described as very powerful and tenacious with a sweet, creamy, nut-like, and fruity undertone (Arctander, 1961; Burdock, 2010).
It is a colorless, viscous liquid that is almost insoluble in water but soluble in alcohol and oils. It has a specific gravity of 0.97 (Arctander, 1961; Burdock, 2010).
Its empirical formula is C10H18O2, and its molecular weight is 170.25 (Arctander, 1961; Burdock, 2010).
The boiling point of δ-Decalactone is 281°C (Burdock, 2010).
The aroma threshold value for δ-Decalactone is detected at 100 ppb (Burdock, 2010).
The taste characteristics at 2 ppm include waxy, coconut, lactonic, fatty, creamy, nutty, and fruity notes (Burdock, 2010).
Natural Occurrence
δ-Decalactone occurs naturally in various foods including rum, coconut, raspberry, apricot, bilberry, peach, strawberry, Swiss cheese, other cheeses, butter, milk, milk powder, mutton fat, mango, and nectarine (Burdock, 2010).
It has also been reported found in butter, milk, beer, rum, red and white wine, guava, plums, prunes, starfruit, peach, and strawberry (Burdock, 2010; Arctander, 1961).
Uses and Applications
δ-Decalactone is used in flavor compositions such as peach, mango, strawberry, chocolate, and less commonly in milk, cream, butter, and cheese (Arctander, 1961; Burdock, 2010).
In perfumery, it is utilized in floral compositions, particularly gardenia and other heavy floral types, often in combination with synthetic musks (Arctander, 1961).
It is employed in various food products with the following reported usage levels (in ppm):
Alcoholic beverages: usual 3.00, max 6.50
Baked goods: usual 13.52, max 26.40
Frozen dairy: usual 18.78, max 37.06 (Burdock, 2010; Arctander, 1961).
The material is also used in oleomargarine where its flavor is enhanced in combination with δ-Dodecalactone (Arctander, 1961).
Production Methods
δ-Decalactone can be produced from hexyl ethylene oxide and sodium malonic ester, by lactonization of decanoic acid, and other methods involving microbial conversion and chemical synthesis (Arctander, 1961; Rowe, 2005).
An industrial method includes the microbial conversion of ricinoleic acid (from castor oil) via partial β-oxidation to produce δ-Decalactone with a peach-like aroma (Rowe, 2005).
Regulatory Status
δ-Decalactone is generally recognized as safe (GRAS) by the Flavor and Extract Manufacturers Association (FEMA No. 2361) and approved by the FDA for use in food flavors (21 CFR 172.515) (Burdock, 2010).
The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has no safety concern at current levels of intake when used as a flavoring agent (1997) (Burdock, 2010).
