A Method Of Preparing For Preparing A Translucent Soap Bar And A Translucent Soap Noodle

Abstract: A method for predicting an impact of at least one crystalline phase in a translucent soap noodle, for achieving a desired level of the translucency in the translucent soap bar obtained from the translucent soap noodle, is predicted. In an aspect, to achieve the desired level of the translucency, Omega Phase Parameter value of the omega crystalline phase in the translucent soap noodle is less than about 35 (J/g)(oC). Further, a proportion of the Omega Phase Parameter value of the omega crystalline phase to the Beta Phase Parameter value of the beta crystalline phase is in the range from about 1:1 to about 1:6, preferably in the range from about 1:2 to about 1:4. Further, the present subject matter includes a method for preparing the translucent soap bar that exhibits a desired level of the translucency, i.e., about 35% to about 45%.
