SYNOPSIS OF FINDINGS
'
1 Eight talcs were investigated The talcs are clean
Each talc was found to be free from asbestiform
minerals by several analytical procedures
2 All tales assayed greater than 90 pure talc mineral content in conformance to updated CTFA cosmetic talc
definitions
3 The report covers only eight talcs of twelve talcs expected As of the close of 1977 J & J Japan had not yet obtained their scheduled shipments and are not represented in this issue
Brazilian talcs
never reached us
although sent to and are presumed
us on two occasions lost in U.S. Customs
4 This report includes an important document IC8751 recently released by the U. S. Bureau of Mines The document officially defines specifics of asbestiform minerals The report will provide valuable technical reference support in any future talc asbestos controversies
Protected Document to Protective Order
JNJNL61_000012049
FREEDOM FROM ASBESTOS BY ELECTRON MICROSCOPY
The talcs were examined by Scanning Electron Microscopy in a system equipped with an Energy Dispersive Ray Analyzer The work was conducted at one of the leading microanalysis laboratories in the U.S.A. and xerox copies of certificates of purity for each of the talcs are presented Any overseas J & J affiliate requiring a photostatic
copy of the original of their purity certificate
may obtain one by request to Applied Research Baby Products Company Raritan New Jersey U.S.A.

ASBE FROS M AT SBO ESTS OS
BY CTFA METHOD
All talcs passed the freedom from fibrous amphibole test prescribed in CTFA J4-1 as prescribed in the
latest issue of Cosmetic Talc specification by the
Cosmetic Toiletry and Fragrance Association of the
U.S.A.
However the Australian talc did show presence of an amphibole by the ray part of the test but it was easily classified as fibrous asbesti-
form by the dispersion staining technique
This finding is
is no cause for
ing part of the
encountered very occasionally and concern since the dispersion stain-
test reads asbestiform

OPTICAL MICROSCOPY
The attached table of findings sums up Petrographic
examinations Two of the talcs are not up to the
platiness of the others Australia and Pakistan both show about 20 platy talc That represents no change for Australia but the Pakistan talc of 1977 is now less platy than the 1976 sample The attached notation of a trace of fibrous amphibole perceived in the Thailand talc is for research reference only
