Abstract:
A bar composition comprising:(a) 25 to 85% by weight fatty acid soap; (b) polyalkylene glycol having MW of 400 to 25,000 Dalton; (c) C8 to C20 free fatty acid; (d) 0.1 to 5% by wt. of a salt of protic acid having pKa1 less than 6; wherein the amount of polyalkylene glycol (b) present in the bar is sufficient to improve skin condition in controlled application wash tests either by reducing the barrier damage as measured by transepidermal water loss, increasing skin hydration as measured by skin conductivity/capacitance, and/or by reducing visual dryness; wherein, the molar equivalents ratio of free fatty acid (c) to protic acid salt (d) is between 0.5:1 to 3:1, and the weight ratio of free fatty acid (c) to the sum of weights of polyalkylene glycol plus organic protic acid salt ((b) and (d)) is 1:2 to 2:1.
