Claim 0:
1. A liquid lamellar composition comprising:
1) 0.1 to 10% by weight of acyl isethionate comprising sodium lauroyl isethionate;
2) 0.1% to 10% by weight of a methyl acyl taurate comprising sodium methyl lauroyl taurate, sodium methyl cocoyl taurate or a mixture thereof;
3) 0.1 to 20% by weight structurant comprising caprylic acid, lauric acid, myristic acid or a mixture thereof;
4) 0.1 to 10% by weight of a zwitterionic surfactant comprising cocamidopropyl betaine; and
5) 0.0 to 8.0% by weight nonionic surfactant, wherein the zwitterionic surfactant comprises cocamidopropyl betaine, with the proviso that surfactant is at a sum of less than 20% by weight and the composition does not simultaneously comprise 0.0% by weight zwitterionic surfactant and 0.9% by weight nonionic surfactant, and further wherein the weight ratio of methyl acyl taurate to acyl isethionate surfactant is between 1.1:1 to 1:1.15, the composition has 0 to 15% by weight glycerol, a pH from 6 to 7.3, less than 0.2% by weight sulfate-based surfactant, a preservative and a structurant comprising caprylic acid, lauric acid, myristic acid or a mixture thereof.
