Abstract
The present invention relates to process for producing bars comprising 20 to 70% by wt. acyl isethionate and 15% to 35% free fatty acid and which is made by process where excess fatty acids made during production of acyl isethionate is removed by neutralization rather than by “stripping”. The bar retains remarkably desirable consumer properties.
