Abstract
A translucent antibacterial soap is made by a process which includes dissolving a normally solid antibacterial material which is resistant to heat and alkali, e.g., 2,4,4'-trichloro-2'-hydroxy diphenyl ether (THDE), in a mixture of components for making such translucent antibacterial soap, which components include soaps of higher fatty acids in liquid form, such as with water in kettle soap, and converting said mixture to transparent soap cakes, preferably by a process which includes partially drying the mixture, working it and extruding it to bar form, which bar may be cut to length and pressed into the final desired translucent antibacterial soap cakes. Preferably, the antibacterial compound, in powder form, is dissolved in a superfatting agent, such as mixed tallow fatty acids and coconut oil fatty acids and/or lanolin fatty acids, and then admixed at elevated temperature with the soaps of higher fatty acids that are a major constituent of the soap cakes to be made. In some instances it may be desirable to at least partially neutralize the fatty acids in which the antibacterial material may be dissolved and such neutralization can be effected prior to or after admixing of the mi…
