' Johnson BABY PRODUCTS COMPANY RARITAN N.J. 08869 Demicronized Talc Project No. 2006.01 Report for February - March 1977 @ OBJECTIVE Develop a commercially practicable talc product having a minimum content of particles 5 microns and below SUMMARY: Talc Additive - Carbowax 400 JBP treated with 0.25 Carbowax 400 has been in aging and periodical testing to determine if the treated product maintains the reduced respirable particle levels imparted initially After three 3 months the data show that no change in respirable dusting propensity has occurred in the treated products The average readings month period were as for the test follows materials over the three 3 66Talc JBP JBP made with JBP + 0.25 demicronized talc + C Carbowax 0.25 Carbowax Conc mg M 20.1 9.3 2.5 0.5 1 The addition of perfume results in a reduction of airborne respirable particles ARP A vs. B. 2 The addition of Carbowax 400 to JBP results in a marked reduction of ARP B vs. C. 729-10 JNJ 000231603 Project No. 2006.01 Report for February 1977 3 A further reduction in ARP results when the JBP is made using demicronized fines removed talc C vs. D. FUTURE The Reduced Respirables Task Force has requested that particle size distribution of the respirable fraction collected from Carbowax 400 treated JBP be determined by automatic scan counting This work is underway At this time our product development group requires of demicronized 66 talc for Market Research testing wax 400 treated JBP 500 lbs of Carbo- Arrangements have been made with the Alpine American Corp. to produce the required material at their facility in Natick Mass during the week of April 25 1977 Prepared by R.
