Delta Dodecalactone
Delta-Dodecalactone is a creamy, coconut-leaning lactone that adds buttery and dairy warmth to flavour compositions. CAS 713-95-1.
The molecule is a six-membered ring lactone (δ-lactone) with a C12 carbon chain, formula C₁₂H₂₂O₂. At room temperature it is a colourless to pale yellow oily liquid with low water solubility.
We source bulk Delta Dodecalactone 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-Dodecalactone has three high-purity flavour grades: racemic, (R)-enantiomer-enriched, and natural-source.
The standard commercial specification is 98 percent minimum by GC, with a clear pale yellow appearance and a refractive index near 1.458 at 20 degrees C.
Both racemic and (R)-enantiomer-enriched grades exist. The (R)-form delivers a softer, more natural coconut note and is often selected for premium dairy reconstructions.
Kosher and Halal certificates are routinely issued. The natural-source grade is produced by biocatalytic conversion of unsaturated fatty acid precursors and qualifies for natural flavour labelling in the United States and European Union.
Applications
- Butter and butterscotch flavour bases for bakery and confectionery
- Coconut and tropical fruit profiles in beverages and ice cream
- Dairy reconstitutions for cream, milk, and condensed milk notes
- Caramel, toffee, and dulce de leche flavour systems
- Peach, apricot, and stone-fruit accords as a creamy background
- Yogurt and cultured dairy top-notes
- Coffee creamer and non-dairy whitener flavourings
- Chocolate and praline compositions for a fatty body
- Tobacco flavourings for a creamy mouthfeel
- Fine fragrance and personal care for soft milky accords

How We Help Source Delta Dodecalactone
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 Dodecalactone 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 Dodecalactone 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-Dodecalactone is approved as a flavouring substance in major regulated markets.
It appears on the FEMA GRAS list as FEMA 2401 and is recognised by FLAVIS under number 10.011. In the European Union it is listed in the Union list of authorised flavourings.
The U.S. Food and Drug Administration recognises it as a synthetic flavouring substance under 21 CFR 172.515. JECFA has evaluated the broader aliphatic lactone group and placed Delta-Dodecalactone in a class with no safety concern at current intake levels.
Both synthetic and natural variants are commonly sold with Kosher and Halal certification.
Manufacturing Process
Two industrial routes dominate Delta-Dodecalactone manufacture.
The synthetic route starts from 2-decanal or dec-1-ene. Addition of acrylic acid or methyl acrylate, followed by hydrogenation and acid-catalysed cyclization, yields the δ-lactone ring. Distillation under reduced pressure gives the 98 percent flavour grade.
The natural route uses biotransformation. Substrates such as linoleic or coriolic acid are processed by selected yeast strains (often Yarrowia lipolytica or Mortierella species), which perform β-oxidation and δ-hydroxylation. Acidification then closes the ring, and the lactone is recovered by solvent extraction or steam distillation.
