Natural Occurrence

Salts of fatty acids formed by neutralizing fatty acids with sodium, potassium, or calcium. Chemically identical to traditional soap when sodium or potassium salts are used.

Animal fatsVegetable oilsPalm oilCoconut oil

Manufacturing

Method: saponification or neutralization

Produced by neutralizing fatty acids (from animal or vegetable sources) with sodium hydroxide, potassium hydroxide, or calcium hydroxide. This is the same process used to make soap.

Applications Beyond Food

Cosmetics

Used in soaps, creams, and lotions as emulsifiers and cleansing agents

Medical

Used in ointments and creams as emulsifying agents

Industrial

Manufacturing of metallic soaps, lubricants, and waterproofing agents

Household

Traditional bar soap (sodium and potassium salts)
