Abstract
The invention is directed to a wash composition that does not irritate the eyes. The composition comprises a surfactant system having anionic surfactant, and amphoteric or zwitterionic surfactant or both, and nonionic surfactant or cationic polymer or a mixture thereof. The composition is water continuous, has a pH from 4.8 to 7.5, and surprisingly, does not irritate the eyes while simultaneously delivering consumer desired lathering characteristics.
Claims16
A composition comprising:
- a) a surfactant component comprising:
- i) amphoteric and/or zwitteronic surfactant;
- ii) nonionic surfactant, cationic polymer or a mixture thereof;
- and
- iii) anionic surfactant the anionic surfactant comprising from 25 to 100% by weight taurate based on total weight of anionic surfactant;
- iv) from greater than 5 to 55% by weight polyol;
- and
- v) water
- wherein the amphoteric and/or zwitterionic surfactant, and nonionic surfactant or cationic polymer or mixture thereof (“component i and ii”, respectively) to anionic surfactant (“component iii”) are at a weight ratio from 1:4 to 2:1 and the amphoteric and/or zwitterionic surfactant (“component i”) to nonionic surfactant, or cationic polymer or mixture thereof (“component ii”) are at a weight ratio from 1:12 to 12:1, with the proviso that when cationic polymer is used alone or with nonionic surfactant, the total weight of cationic polymer used to total weight of surfactant in the wash composition is from 1.3% to no more than 15% by weight of total weight of surfactant and the wash composition comprises 20% or less by weight total of surfactant and cationic polymer and further wherein the amphoteric surfactant comprises a betaine, the cationic polymer comprises hydroxypropyl trimonium chloride and/or hydroxyethylcellulose and the nonionic surfactant comprises a glucamide.
