Their good qualities are so superlatively good, their effect on the complexion, the health and longevxty so unfailing, their -chemical composition in each case so remarkably in accord with all that exact science and dermatological art could produce, that it discourages the medical man, who finds so much in his own measures that are unperf ect and incomplete. Wo read, therefore, with a certain wnse of relief the results of an in-yestigation in-yestigation made by Dr. B. H. Paul on the composition of these highly lauded toilet soaps. Dr. Paul states that for bodily ablution soaps should not contain an excess of alkali but should be nentral or nearly so. Ho found, however, that among toilet soaps, as usually met with, a perfectly neutral soap is the exception, and that a trustworthy soap of that kind is still a desideratum. Three of five soaps of the higher grade were described as "super-fatted" soaps, one of them being be-ing alleged to have been prepared ac-cording ac-cording to Unna's formula. But, in fact, they all were found to contain the full proportion of alkali required for the saponification of the fat, besides some additional potash, which, in one of them, was considerable. It seems, therefore, that the perfect soap is yet to be made. Medical Record. |
