Isopropyl myristic ester is a chemical compound from the group of carboxylic acid esters and is an ester of myristic acid .
Occurrence
Isopropyl myristate comes naturally z. B. in butter , palm kernel oil and coconut fat .
Extraction and presentation
Isopropyl myristate can be obtained by esterifying myristic acid with isopropanol or by transesterifying methyl myristic acid with isopropanol.
properties
Isopropyl myristate is a colorless, odorless liquid and is the isopropyl ester of myristic acid. It has a viscosity of 5-6 mPa · s at 20 ° C and a saponification number of 202-212 mg KOH / g. The flash point is> 150 ° C, the decomposition temperature is 208 ° C.
use
Isopropyl myristate is used as a synthetic chemical. It is used in cosmetics as a spreading and refatting agent and as a solubilizer. It is also used in the local treatment of pediculosis (head lice infestation).
