Claim 6

A detergent bar comprising from about 25 to about 60% of a water-soluble alkali-metal detergent salt of an ester of isethionic acid with mixed aliphatic fatty acids having from 10 to 18 carbon atoms and an iodine value of 0 to about 1, said mixture of fatty acids comprising about 28 to 37% decanoic, about 18 to 24% dodecanoic, about 16 to 21% tetradecanoic, about 9 to 20% hexadecanoic, and about 10 to 17% octadecanoic acids, total esterified acid basis, from 0 to about 10% of at least one water-soluble suds-boosting detergent salt selected from the group consisting of alkali metal and organic amine higher aliphatic fatty alcohol sulfates, alkyl aryl sulfonates, and higher aliphatic fatty acid taurides, from about 1 to about 9% water, from about 2.5 to about 25% of water-soluble higher fatty acid soap, and from 10 to 40% of at least one higher fatty acid having from about 12 to about 25 carbon atoms as a binder and plasticizer, said bar having a pH within the range from 6 to 8, measured as a 10% aqueous solution of the bar composition at 35*C.

Claim 7

A detergent bar comprising from about 25 to about 60% of a water-soluble alkali-metal detergent salt of an ester of isethionic acid with mixed aliphatic fatty acids having from 10 to 18 carbon atoms and an iodine value of 0 to about 1, said mixture of fatty acids comprising about 28 to 37% decanoic, about 18 to 24% dodecanoic, about 16 to 21% tetradecanoic, about 9 to 20% hexadecanoic, and about 10 to 17% octadecanoic acids, total esterified acid basis, from 0 to about 10% of at least one water-soluble suds-boosting detergent salt selected from the group consisting of alkali metal and organic amine higher aliphatic fatty alcohol sulfates, alkyl aryl sulfonates, and higher aliphatic fatty acid taurides, from about 1 to about 9% water, from about 2.5 to about 25% of water-soluble higher fatty acid soap, and from 10 to 40% of at least one higher fatty acid having from about 12 to about 25 carbon atoms as a binder and plasticizer, said bar having a pH within the range from 6 to 8, measured as a 10% aqueous solution of the bar composition at 35*C.
