Sebacic Acid Supplier in Malaysia
- Also known as
- Decanedioic Acid
- 1,8-Octanedicarboxylic Acid
- C10H18O4
Sebacic acid supplier for lubricant, polyamide, plasticiser and corrosion-inhibitor formulators in Malaysia. Its systematic name is decanedioic acid (CAS 111-20-6, C10H18O4), and it is a white to off-white solid traded as flake, crystal or powder.
Most commercial material is made from castor oil derived ricinoleic acid, which places it among the bio-based diacids. Choice on the page is purity and form: technical material for esters, additives and resin modification, refined material where colour, ash and acid value are held tighter.
Four quite different buyers use it. Ester and grease formulators want the C10 chain for thermal stability and low-temperature flow, polymer producers charge it into nylon 6,10 and long-chain polyesters, plasticiser and metalworking blenders build sebacate esters and corrosion inhibitors from it, and coating chemists use it to flexibilise powder and alkyd resins.
Chain length decides identity here. Sebacic acid is the C10 diacid, distinct from the C9 and C6 diacids and from fatty monoacids, and it is not sold on this page as a food acid. Send the grade, form, purity target, volume and destination with the enquiry, and packing, documentation, availability and timing follow with the quotation.

Sebacic Acid grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Technical grade sebacic acid flake | white to off-white flake | purity and acid value set against the required specification | Plasticiser and dibasic ester manufacture, corrosion-inhibitor and metalworking-fluid blending, and coating resin modification where flake is melted or dissolved in the batch. | Bag packing, confirmed with the quotation. |
| Refined sebacic acid | white flake or crystal | tighter colour, ash and acid-value limits against the specification | Polyamide and polyester polymerisation and synthetic ester base fluids, where colour carry-through and low residues matter more than unit price. | Bag packing, confirmed with the quotation. |
| Sebacic acid powder | free-flowing white powder | — | Weighed additions into greases, candle and cosmetic chemistry and laboratory-scale synthesis, where a finer particle dissolves and disperses without a melt step. | Bag packing, confirmed with the quotation. |

Sebacic Acid applications
Safety and handling
Keep bags closed in a cool, dry store away from strong bases and oxidising agents. The dust irritates the eyes and airways, so control it during transfer, wear gloves and eye protection, and work to the safety information issued for the grade quoted.
Common questions about sebacic acid
Is sebacic acid the same as decanedioic acid?
Yes, same material. Decanedioic acid is the systematic form of the name and 1,8-octanedicarboxylic acid the older equivalent, both covering CAS 111-20-6 and formula C10H18O4. Whichever name your specification carries, send the form and purity the process needs with it.
How does sebacic acid compare with the C9 and C6 diacids?
Chain length is the difference, and it is not interchangeable. Sebacic acid is the C10 diacid, azelaic acid the C9 and adipic acid the C6, and each gives different chain flexibility, melting behaviour and ester properties. Name the one your specification calls for, since substituting changes the product.
Which sebacic acid grade and form should I ask for?
Technical flake covers plasticiser esters, metalworking additives and resin modification. Refined material suits polyamide and polyester polymerisation and ester base fluids, where colour and residue limits are tighter. Powder suits weighed additions and laboratory work. Send the purity target and the process and the grade can be matched.
Is sebacic acid a food acid?
No. It is an industrial dibasic acid for lubricant, polymer, plasticiser and corrosion-inhibitor chemistry, and this page does not cover it as a food acidulant or offer it for that use. Where a formulation needs an edible acid, ask for that acid by name instead.
Is sebacic acid the same as dioctyl sebacate?
No. Dioctyl sebacate and the other sebacate esters are made by reacting this acid with an alcohol, and they are separate products with their own specifications and handling. Request the ester by name where a finished plasticiser or ester fluid is what the process needs.
What should a sebacic acid enquiry include?
Give the application, form, purity or colour target, volume and delivery point, and mention any documentation your quality system expects. A stated specification lets the offer be built against a defined grade rather than a generic one.
