b. neutralizing the molten mix by adding sodium hydroxide under stirring conditions to obtain a neutralized mixture;
c. adding at least one surfactant, and water to obtain a soap mixture; and
d. pouring said mixture into moulds to allow solidification at a temperature in the range of 22-32°C.
9. The process as claimed in claim 8 further comprising addition of NaCl, preferably before step (d) of claim 8.
10. A process of preparing a transparent soap bar as claimed in claim 7, said process comprising:
a. melting hystric acid, lauric acid, glycerin, and propylene glycol at a temperature in the range of 65-90°C under continuous stirring in a first vessel to obtain a molten mix;
b. neutralizing the molten mix by adding sodium hydroxide under stirring for 5-30 minutes to obtain a neutralized mixture;
