Pellets of paraffin wax implanted into the lumen of the bladder of 38 mice induced one carcinoma. An equally low incidence of carcinomas was induced with paraffin wax pellets containing 15-20 per cent suspensions of 8-hydroxyquinoline or quinaldic acid, 8-hydroxyquinaldic acid, xanthurenic acid, the 8-methyl ether of xanthurenic acid, 4,8-quinolinediol, L-kynurenine sulfate, 3-hydroxy-L-kynuren...

The waterproofing effect of a number of creams, oils, and greases was examined by measuring water loss from adult skin before and after topical application. Creams had a high water content and were ineffective, oils produced a modest fall in water loss, but paraffin in grease form had a pronounced, sustained waterproofing effect. A paraffin mixture (80% soft, 20% hard paraffin (BP) was then app...
