Abstract
A novel combination soap bar effective in hard water is disclosed which is comprised of a major amount of a fatty acid soap and a minor amount of an alkali metal, amine or ammonium salt of an N-2(2-hydroxyethoxy)ethyl fatty amide-H-sulfate containing about 12 to 18 carbons in the fatty amide chain. The inventive combination bar produces a stable lather when used in hard water, yet will not produce a scum or insoluble precipitates. The novel combination bar may also include other ingredients such as perfumes, deodorants, anti-microbial agents, emollients, and other surfactants and processing aids, such as fatty acids, starch, polyethylene glycol, and the like.
Claims5
A combination soap bar effective in hard water that produces a stable lather and is substantially resistant to scum formation in the presence of hard water, said bar comprising:
- about 80% by weight of a fatty acid soap of sodium, potassium or mixtures thereof wherein at least about 80% of said fatty acid soap is in the form of the sodium salt, and wherein at least 70% by weight of said fatty acid soap is a tallow soap;
- and
- about 20% by weight of an alkali metal, amine or ammonium salt or mixtures thereof of an N-2(2-hydroxyethoxy)ethyl fatty amide-H-sulfate containing 12 to 18 carbon atoms in the fatty amide chain.
