Johnson BABY PRODUCTS COMPANY : RARITAN N.J. 08869 Demicronized Talc ProjecNot. 2006.01 Report for April - May 1977 OBJECTIVE Develop a commercially practicable talc product having a minimum content of particles 5 microns and below SUMMARY: A Airborne Respirable Particles ARP Particle Size Distribution of PEG Treated Talc Particle size distribution by optical microscopic count of ARP from the following PEG treated powders has been determined and reported Project 2006.01 4/25/77 a JBP - Control 0 JBP 0.25 PEG C. JBP with demicronized talc 0.25 PEG The results showed that the ARP fractions from powders a b and c all had maximum particle counts in the 6-7 micron range The distribution curves for samples a & b are about the same however the curve for the demicronized talc c shows a sharp decrease in particles in the range below 6.7 microns This would be expected since many of these particles were previously removed by the demicro- nization process B Market Research Testinogf PEG Treated JBP 500 lbs of demicronized 66 talc was prepared at Alpine American Corporation by material has been delivered to air the classification This BPC Product Development group for use in Market Research Testing of PEG treated JBP Prepared by R.
