EXAMINATIO N OF JOHNSON AND JOHNSON 'S BABY POWDER Summary Two samples of Johnson and Johnson 's Baby Powder, batch number 108T and 109T, which correspond to the samples exam ined by Professor Seymour Z . Lewin of New York University on behalf of the FDA have been exam ined by x-ray diffrac tion, light m icroscopy , transmission electron microscopy and electron diffraction to determine whether they contain any asbestiform minerals. Both samples contained an insignific ant amount oftremolite a few isolated crystals. Neither sample contained chrysotile. Introduction On behalf of the FDA, Professor Seymour Z. Lewin of New York Univer sity is examining a number of commercial talcum powders for the presence of asbestiform miner al s. Two of the samples which he has examined are samples of Johnson and J ohnson's Baby Powder, batch number 108T and batch number 109T. Johnson and J ohnson therefore requested Walter C. McCrone Associates to examine samples from the same batches to determine whether they contained any asbestiform minerals. Materials and Method of Conducting Tests Two samples were submitted, identified as Johnson and Johnson's Baby Powder, batch numbers 108T and 109T. For x- ray diffrac tion examination, the samples were examined on a Phillips-Nor elco verticle diffr actometer using CuKa radiation and a scanning speed of 1 o per minute. The dispersion staining teclmique was used for the light microscopical examination and the el ectron microscopy- electron diffraction examination was carried out us ing procedures previously described (MA report 2330-1 ; dated 10 August 1971). walter c. mecrone associates, inc. JOJO-MA2546-01487 Results X-ray Diffraction The diffractograms were carefully examined in the vicinity of the major peaks of chrysotile and iTemolite. Neither mineral was present. The presenc e of peaks in the vicinity of 12. 0-12-5° 28 , the region in which one of the principal lines of chrysotile may be found, was correlateq with peaks in the vicinity of 6° 28 and are thus attributable to chlorites . No significant peaks were observed in the 24° region which would be required were chrysotile present. L ight Microscopy Using the disper s ion staining technique and a liquid of r efractive index 1.550, the samples were examined for chrysotile particles and fibers, but none could be found. Using a similar technique with a liquid of refractive index 1. 605, the samples were similarly examined for the presence of tremolite and a few individual crystal s were found, some rod shaped. El ectron Microscopy and Electron Diffraction Several el ectron microscope gr ids from both samples were examined in their entirety and although some fibers were observed these were shown by electron diffraction to be shards of talc or rolled talc. No chrysotile fibers were found. Conclusion A detailed examination of two samples of Johnson and Johnson's Baby Powder, batch numbers 108T and 109T has shown this material to be substantially free of asbestiform minerals. A few tremolite rods were observed in both samples. No chrysotile has been detected . Respectfully submitted, Ian M. Stewart Manager, E lectron Optics Group walter c . mecrone associates, inc.
