Abstract
The invention relates to lamellar liquid composition comprising acyl isethionate, methyl acyl taurate, amphoteric and/or zwitterionic surfactant. Unexpectedly, applicants have found that, when ratio of isethionate to taurate is kept at about to 1:1, enhanced lather is achieved. Other criticalities include ratio of amphoteric and/or zwitterionic to anionic surfactant, total amount of surfactant, and pH.
