    Abstract: The ocular irritancy of aqueous shampoo compositions containing from about 1 to 20% by weight of an eye irritating anionic surfactant such as a C.sub.8 -C.sub.18 alkyl sulfate containing from 0 to about 4 ethyleneoxy units is reduced by the addition of from about 0.01% to 5% of an ethylene oxide homopolymer. The homopolymer has the formula H(OCH.sub.2 CH.sub.2).sub.x OH where x has a value such that the weight average molecular weight of the homopolymer is between about 100,000 and 5,000,000, preferably between about 500,000 and 4,000,000.
