TGG: JCL: ERT: MJH^AJO: RF TO: Jim Hackett, Joe Nigro, Greg Hoenes XF:___________ 59^ Interoffice Communication FROM: DATE: SUBJ: T. G. Grumbles December 6, 1989 MICHELMAN INC. CUSTOMER COMPLAINT: DISPAL SOL 120 VISTA Below is a summary of the items revealed in my call with Dave Capella of Michelman regarding skin irritation complaints from a customer of theirs. 1. He did not have a lot of details but felt there were two complaints from one customer. 2. The customer has a paper application, and Capella believed they were spraying the material. He did not know if this customer was a "silica substituter". 3. He was surprised at the skin irritation complaint based on the "dilution" of product that occurs. Michelman "cuts" it by 1/3 and he believes the customer cuts that back by 1/5. This would result in less than .1% acid by weight. 4. The customer's employee contact would be with an aqueous solution. 5. Michelman will continue to investigate the complaint. I'll call them in a week to see what else they've learned. T. G.
