[Procurement and supply of tetradecanoic acid] List of basic physical and chemical information of tetradecanoic acid

Tetradecic acid, also known as myristic acid, is made from coconut oil and palm oil The obtained mixed fatty acids or fatty acid methyl esters are obtained by vacuum fractionation and used as raw materials for soaps, soaps, detergents, cosmetic surfactants and chemical fiber oils; to manufacture emulsifiers, waterproofing agents, curing agents, and polyvinyl chloride heat stabilizers. Agents and plasticizers, etc., and also raw materials for spices and medicines.
