Lauric acid, also known as lauric acid, is a saturated fatty acid . Its molecular formula is C12H24O2. It is white needle-shaped crystals with a slight scent of laurel oil. Insoluble in water, soluble in methanol, ether, chloroform and other organic solvents, slightly soluble in acetone and petroleum ether.

The following suppliers of lauric acid will help you understand the technical indicators and purity identification of lauric acid:

Neutralization value 277~284, iodine value below 1, traces of moisture, traces of ash, traces of unsaponifiable matter, melting point 42~45℃.

The basic specifications of lauric acid used as cosmetic raw materials are: acid value 275~285, iodine value less than 1, melting point 32-45°C, ester value less than 3, strong heat residual content less than 0.1%. The purity of lauric acid with an acid value above 277 mg KOH/g is greater than 95%.

The appearance of lauric acid can also reflect the purity of the product. After cooling and solidifying, lauric acid with a purity of more than 99.5% will show coarse “ice flowers” on the surface. The crystals are relatively large and easy to crush. As the purity decreases, the “ice flower” pattern becomes less and less obvious, and lauric acid with less than 95% can no longer form “ice flower” crystals.

The indicators of lauric acid products in my country are as follows.
