  • Patent number: 5041234
    Abstract: A transparent soap composition in bar form comprises with respect to the total composition 40 to 65 wt % of a soap mixture and 60 to 35 wt % of a solvent system. The solvent system includes with respect to the total composition 5 to 15 wt % short chain (C<4) monohydric alcohol or a mixture of said monohydric alcohols, 5 to 20 wt % water and 15 to 40 wt % of a mixture of trialkanolamine and polyol or blend of polyols, the said mixture having a ratio in weight terms of trialkanolamine to polyol or polyols lying within the range 1:3 to 1:0.25, the total composition comprising not more than 20 wt % trialkanolamine. The resulting soap bar has good transparency in combination with user properties approaching those of an ordinary opaque soap bar. The present transparent soap bar can be made by forming an isotropic transparent melt of the composition, casting the melt into moulds and allowing the melt to set.
