Abstract

The invention relates to concentrated liquid cleansing compositions in lamellar phase which possess a lotion-like appearance conveying signals of enhanced moisturization. The use of a specific ratio of synthetic anionic surfactant(s) and co-surfactant(s) to fatty acid(s) in a structured liquid product was found to improve lather production by moderating or eliminating the increase in viscosity upon dilution. In a further embodiment, specific small hydrophobic molecules were found to improve freeze/thaw stability and thereby cause the inventive composition to maintain noticeable moisturization signals.
