Myristic Acid

Whatsapp Order

Myristic Acid is a saturated fatty acid with a 14-carbon chain, naturally found in nutmeg, coconut oil, palm kernel oil, and butter fat. It appears as a white crystalline solid with a faint odor. It is widely used in the manufacture of soaps, cosmetics, surfactants, and food additives due to its emollient and cleansing properties. Myristic Acid acts as a key intermediate in the production of esters, detergents, and lubricants.
