Toilet soap with improved lather
The present invention relates to soap bars having improved lather. Specifically, by limiting amounts of myristic acid and keeping specifically defined ratios of sum of C 8 -C 10 fatty acids to C 12 fatty acid bars having substantially improved lather and unexpectedly obtained.
1. Soap bar composition comprising:
a) a fatty acid soap blend in an amount of 30 to 90% by wt. of the soap bar comprising:
(i) caprylic, pelargonic and capric acids, their salts or their mixtures thereof in an amount of 0.1 to 40 wt. % of the fatty acid soap blend;
(ii) myristic acid in amount not higher than 8 wt. % of the fatty acid soap blend;
b) co-adjuvants selected from polyols, polymers, organic and inorganic adjuvants, electrolytes, benefit agents and other minor ingredients in an amount from 0.1 to 50% by weight of the soap composition;
c) the remainder of water;
wherein the fatty acid blend comprises a ratio of the sum of caprylic, perlagonic and capric acids to lauric acid, (ΣC 8-10 /C 12 ), of 0.5 to 2.5.
2. A soap bar according to claim 1 wherein the fatty acid blend comprises lauric acid in an amount of 0.1 to 35% by wt. of the fatty acid soap blend.
3. A soap bar according to claim 1 wherein the fatty acid blend comprises the sum of capric, pelargonic and caproic acids in an amount of 10% wt. to 40% wt. of total fatty acids.
4. A soap bar according to claim 1 wherein the fatty acid blend comprises myristic acid in an amount of 1% wt. to about 7% wt. of total fatty acids.
5. A soap bar according to claim 1 wherein said fatty acid blend further comprises a linoleic acid in an amount less than 15% by wt. of total fatty acids.
6. A soap bar according to claim 1 , wherein said fatty acid blend further comprises the sum of palmitic and stearic fatty acids in amount of about 7 to about 70% by wt. of total fatty acids blend.
7. A soap bar according to claim 1 , wherein said fatty acid blend further comprises 0.01 to about 7% of free fatty acids.
8. A soap bar according to claim 1 producing about 370 ml of lather according to the lather volume test.
9. A bar according to claim 2 , wherein ratio of sum of C 8 -C 10 to C 12 is from 0.5 to 2.0.
10. A bar according to claim 2 , wherein blend comprises 8 to 16% lauric acid.
11. A bar according to claim 5 , wherein linoleic acid in said blend comprises less than 6% of total fatty acid.
12. A bar according to claim 11 , wherein linoleic comprises less than 2% of total fatty acid.
13. A bar according to claim 6 , wherein sum of palmitic and stearic is 15 to 60% by wt. of total fatty acid.
