1. An aqueous liquid wash composition comprising:
(a) a preservative comprising benzoic acid and/or a derivative thereof;
(b) an anionic surfactant comprising sodium lauryl sulfate, sodium lauryl ether sulfate or mixtures thereof, and sodium lauryl isethionate, sodium methyl lauryl taurate or mixtures thereof;
(c) a zwitterionic surfactant comprising a cocamidopropyl betaine or a mixture thereof;
(d) 1 to 9% by weight of a polyol;
(e) water and;
(f) 0.01 to 6% by weight of vitamin B2, B3, B6, Vitamin C or a mixture thereof, the composition having a water activity under 1, a pH from 6 to 7 and wherein the weight ratio of zwitterionic surfactant to anionic surfactant is from 1:8 to 1:2, the isethionate is at least 50% by weight of a lauroyl isethionate and the composition comprises less than 7.5% by weight sulfate-based surfactant and further wherein the preservative is 90 to 100% by weight benzoic acid and/or a derivative thereof and the composition has a viscosity from 750 to 22,000 cps, 4 to 15% by weight anionic surfactant, 1 to 5% by weight betaine where the betaine is at least 65% by weight cocamidopropyl betaine, the composition further comprising 40 to 90% by weight water and thickener, the thickener being present at 0.8 to 3.5% by weight when the aqueous liquid wash composition comprises petrolatum.
