Transparent soap bar - Patent 3969259 |
 | | This property of insolubility in a soap mass during processing to a transparent state is shared by the well-known phenolic germicides heretofore disclosed as useful in the conventional milled soap bars, for example, 2,2'methylenebis(3,4,6-trichlorophenol), 2,4,4'-trichlorocarbanilide, and 3,4',5-tribromosalicylanilide and the 4',5 -analogue thereof, as well as 2,4,4'-trichloro-2'-hydroxy diphenyl ether. |
 | | Useful soaps are the salts of fatty acids having about 12 to about 22 carbon atoms, with small proportions of fatty acids having 6-10 carbon atoms when coconut or other tropical nut triglyceride oils are included in the fat charge from which at least a portion of the soap is derived. |
 | | The soap at this reduced moisture content is still molten, and is next chilled rapidly on a chill roll to a temperature of 80.degree.-85.degree.F, the soap leaving the chill-roll in the form of chips. |
