Abstract
The invention is directed to a mild liquid composition with enhanced antimicrobial activity. The liquid composition of the present invention is mild and unexpectedly yields superior antimicrobial activity when used in cleansing applications. The liquid composition comprises an anionic surfactant and an acid, and is formulated to yield a wash solution having a pH from 2.9 to 5.2.
Claims13
A liquid composition comprising:
- a) from 2 to 20% by weight anionic surfactant;
- b) from 0.2 to 8% by weight of at least one acid having a pKa from 1 to 8 and a log P from 0 to 4.95, wherein the acid is benzoic acid, salicylic acid or a mixture thereof;
- c) water;
- and
- d) optionally, a liquid structuring agent,
- wherein the composition in a 50% aqueous solution has a pH from 2.9 to 5.2 and further wherein the composition is substantially sulfate free, wherein the anionic surfactant is 95 to 100% by weight of a taurate based on total weight of anionic surfactant, and the composition further comprises 7 to 40%, by weight zwitterionic surfactant based on total weight of anionic and zwitterionic surfactant used in the liquid composition, whereby 1.8 to 3.2%, by weight acid having a pKa from 1 to 8 and a log P from 0 to 4.95 is used based on total weight of the liquid composition when the composition has a pH from 3.5 to 4.5.
