Delta Decalactone
Delta-Decalactone is a colourless to pale yellow oily liquid with a creamy, buttery, coconut-like aroma carrying a soft peach undertone.
The compound has the molecular formula C₁₀H₁₈O₂ and CAS number 705-86-2. It is a six-membered lactone formed by intramolecular esterification of 5-hydroxydecanoic acid, and it is one of the most important dairy-creamy character molecules in the flavour industry.
We source bulk Delta Decalactone from top China manufacturers for our partners. The manufacturer is in Jiangsu. A smaller requirement can ship in a combined container with other ingredients.
Please send the grade you need, the volume and your destination port, and we will come back with a solution and a price.

Common Markets Grades
Delta-Decalactone trades in three grades: a nature-identical synthetic, a fermentation-derived natural, and a 99 percent quality for fine fragrance work.
The nature-identical synthetic grade assays at a minimum of 98 percent and meets the Food Chemicals Codex monograph. Specifications include acid value, refractive index, and colour in APHA units.
A natural grade produced by fermentation runs at a minimum 97 percent assay and carries a natural label under U.S. and EU flavour regulations. The natural grade is generally a defined enantiomeric mixture that matches the form found in milk fat.
A premium 99 percent grade with tight colour specifications is produced for fine fragrance and high-end dairy flavour compositions.
Applications
- Butter, cream, and milk flavour systems as the primary creamy lactone
- Cheese flavours including blue cheese, parmesan, and aged cheddar accords
- Coconut flavour compositions as a fatty rounding note
- Ice cream and frozen dessert flavours for creamy mouthfeel
- Yogurt and cultured dairy products as a buttery modifier
- Bakery flavour systems for pastry cream, custards, and buttery cake bases
- Caramel, toffee, and butterscotch flavour compositions
- Peach, apricot, and stone-fruit accords as a creamy rounding lactone
- Tropical fruit flavours including mango, passionfruit, and pineapple
- Beverage applications including dairy-based drinks and cream liqueurs
- Fine fragrance for skin-musk, gourmand, and creamy floral accords
- Personal care including body lotion, shower gel, and shampoo

How We Help Source Delta Decalactone
Direct Factory Sourcing
We run the whole process: selecting the manufacturer from the top Chinese food ingredient producers, negotiating the price, verifying quality, and coordinating the logistics. You deal with us instead of with several factories at once.
Original Packaging and Documents from the Manufacturer
The manufacturer sends your Delta Decalactone out of its own factory in the original packing, through to your destination port. The COA, COO, MSDS, TDS and any certifications reach you from the manufacturer as well.
Free Samples and Lead Time
We send 100 to 500 g free for your own laboratory to test and you cover only the courier, usually within 2 to 3 working days. ETD is usually within 7 to 15 days once the order is confirmed, and we check that date against the factory's own manufacturing schedule before we give it to you.
Combined Shipment
We can load Delta Decalactone together with other ingredients such as Capsicum Oleoresin, Ethyl Maltol and White Pepper into one 20' FCL. If your quantity is small, we can also ship LCL.
Regulatory Status
Delta-Decalactone is accepted as a flavouring substance worldwide.
FEMA has assigned GRAS number 2361 for use as a flavour in food. The U.S. Food and Drug Administration permits both synthetic and natural forms, with the natural form qualifying under 21 CFR 101.22 and the synthetic form under 21 CFR 172.515.
The European Food Safety Authority evaluated the molecule within flavouring group FGE.10 and concluded that no safety concern arises at typical dietary exposure. It carries FL number 10.014 in the Union list of flavourings.
JECFA reviewed the lactone group and raised no objection at current use levels. The Council of Europe lists the substance under number 227.
Japan and Korea permit the substance under their respective flavour regulations. Reference material is produced from major analytical-standards suppliers.
Manufacturing Process
Two industrial routes account for nearly all global supply.
The synthetic route starts from 2-decenoic acid or from 1-decene. Hydration places a hydroxyl at the C5 position, and the resulting 5-hydroxydecanoic acid cyclizes spontaneously on distillation to give the six-membered delta-lactone. The product is racemic.
The dominant modern route is microbial fermentation. Selected strains of Yarrowia lipolytica, Mortierella alpina, and other lipid-metabolizing microorganisms are fed coconut or palm-kernel oil hydrolysates. The microbes carry out partial beta-oxidation to produce 5-hydroxydecanoic acid as an intermediate, which lactonizes to delta-decalactone. The product is recovered by solvent extraction or steam distillation.
The fermentation route produces an enantiomeric mixture similar to that found in nature and qualifies as natural under U.S. and EU flavour regulations.
Major producers include IFF, Robertet, Symrise, BASF, and several Chinese fermentation specialists. As with gamma-decalactone, the natural fermentation grade has become the volume leader on the back of natural-flavour demand.
