Abstract
The invention relates to liquid cleansing compositions in lattellar phase which possess a lotion-like appearance conveying signals of enhanced moisturization. However, these liquids often undergo an irreversible decrease in viscosity under freeze/thaw conditions, losing their moisturization signals. The use of low salt levels in amphoteric and anionic surfactants in a structured liquid product has been found to improve its freeze/thaw stability.
