Sodium palmitate also known as sodium tallowate is sodium salt or ester of triglyceride of fatty acid such as palmitic acid with molecular formula C16H31NaO2. It is made up of common saturated fatty acid found in fat and waxes including olive oil, palm oil and body lipids. It is white powder or white blocks or noodles in appearance with soapy sense, fat taste. It acts as an emulsifying agent, surfactant and realising agent. It is a major component of domestic soap and detergent industry.
