Abstract
A bar composition comprising: a) 10%-60% synthetic (non-soap) surfactant; b) 0%-50% fatty acid and soap wherein total fatty acid soap is less than 60% of total synthetic surfactant; c) 6.8%-54% water-soluble structurant, selected from • polyalkylene oxides having MW 1,500-10,000, • PEO-PPO blockcopolymers, wherein the water soluble structurant has a melting point of 40-100° C. and further comprises polyalkylene oxides having MW 50,000-500,000, 1-5 wt %; d) 0.1%-4.8% alkali metal isethionate; e) 2.7%-13.5% water, wherein the sum of water, alkali metal isethionate and water-soluble structurant is 10%-60%, wherein based on the total amount of water, alkali metal isethionate and said water-soluble structurant, • water is present 4-27%, • alkali metal isethionate is present less than 8%, • water-soluble structurant is present 68-90%. Use of the composition for eliminating efflorescence.
