Lauryl Myristyl Alcohol is a chemical compound widely used in the cosmetics, pharmaceuticals, and detergents industries. It is actually a mixture of two fatty alcohols: lauryl alcohol (with 12 carbon atoms) and myristyl alcohol (with 14 carbon atoms).

Structure and Properties

Structure: Lauryl myristyl alcohol has a long hydrocarbon chain and a hydroxyl group (-OH) at the end of the chain. This structure gives it amphiphilic properties, meaning it has both a hydrophobic part (hydrocarbon chain) and a hydrophilic part (hydroxyl group).

Surfactant: Due to its amphiphilic structure, it acts as a surfactant and can reduce the surface tension between two phases (such as oil and water).
Emollient: It makes the skin and hair soft and supple.
Emulsifier: Can form stable emulsions of oil in water or water in oil.
Thickener: Gives thickness to some formulations.
Applications

Cosmetics:
Shampoos and conditioners: Used as surfactants, emollients, and emulsifiers.
Lotions and creams: Used as emollients and emulsifiers.
Makeup removers: Used as emulsifiers to remove makeup.
