Full Description

Lauric Acid (CAS 143-07-7), or dodecanoic acid, is a saturated C12 fatty acid present in coconut and palm-kernel oils, supplied as a white solid. It is used in the manufacture of soaps and detergents, as a feedstock for surfactants and esters, and as an emulsifier and wetting agent. Additional uses include alkyd resins, cosmetics, and food additives.

Frequently Asked Questions

What is lauric acid used for?

Lauric acid is a C12 saturated fatty acid used as a feedstock for soaps, detergents, surfactants, and fatty esters, and as an emulsifier and wetting agent. It is also used in alkyd resins, cosmetics, and as a food additive.

What foods are high in lauric acid?

Lauric acid occurs naturally at high levels in coconut oil and palm-kernel oil, which are the principal commercial feedstocks. The supplied material is a refined dodecanoic acid produced from these oils.

What is lauric acid made from?

Commercial lauric acid is produced by hydrolyzing and fractionating coconut or palm-kernel oils to isolate the C12 fatty acid (dodecanoic acid, CAS 143-07-7), then purifying it to a white solid.

What is the formula and CAS number for lauric acid?

Lauric acid is dodecanoic acid with molecular formula C12H24O2 and CAS number 143-07-7. It classifies under HS code 2915.90 as a saturated acyclic monocarboxylic acid and is supplied as a white solid.

How do I buy bulk lauric acid?

RawSource supplies lauric acid in bulk bags, drums, and bulk quantities with a CoA and SDS. Submit an RFQ with your target grade, volume, and packaging for a current bulk quote rather than a per-unit retail price.
