It has been found that transparency and water-white appearance of soap bars are improved by adding a fluorescer at selective levels. Disclosed is a transparent soap bar comprising: (i) 20 to 78 wt.% total fatty matter; and (ii) 0.003 to 0.5 wt.% fluorescer, wherein (i) CIELAB b* value of said bar at 0° viewing and 75° illumination is less than 0; and (ii) color of said bar expressed as Y+5R on Lovibond (LOVIBOND®) scale is 0 to 3 and wherein the soap bar includes 0.05 to 10 wt.% Cto Calcohol. Also disclosed is a process for making transparent soap bar comprising the steps of: (i) saponification of oils or fatty acids in presence of polyols to get a molten mass, where after complete neutralisation, the free alkali content measured as sodium hydroxide is not greater than 0.1%; and (ii) molding said molten mass to get the bar, wherein 0.003 to 0.5 parts fluorescer and 0.05 to 10 parts Cto Calcohol is mixed with said molten mass. |
