It is a non-ionic surfactant and is classified as a fatty alcohol. With the chemical formula C14H30O and a molecular weight of 214.39, Myristyl Alcohol appears as a white solid at room temperature, with a melting point of 35-39°C and a boiling point of 289°C. It is insoluble in water but is soluble in organic solvents like ethanol, ether, and acetone.
This alcohol is valued for its excellent dispersing, emulsifying, lubricating, and solubilizing abilities.

In terms of safety, Myristyl Alcohol has a low toxicity profile, with LD50 values for rabbits exceeding 5000mg/kg both orally and dermally, indicating it is relatively harmless. It is generally considered non-comedogenic, meaning it does not clog pores or cause acne, and is suitable for vegan and halal products due to its plant-based origins. Overall, Myristyl Alcohol is an important ingredient in the cosmetic and personal care industry for its moisturizing and conditioning properties.
