Why is NaCl added to soap? - FindAnyAnswer.com
Why is NaCl added to soap? The addition of salt (sodium chloride) to the crude form of soap forms fatty-acid salts. The sodium ions from the sodium chloride bond with the fatty acid, forming a product that is less soluble in water. Because of this reduced solubility, the soap leaves the solution and forms a solid mass.
