Vista Chemical Company 900 Threadneedle Houston, Texas 77079-2990 (713) 588-3000 P.O. Box 19029 Houston, Texas 77224-9029 Fax (713) 588-3236 February 4, 1991 David L. Fredrickson Chemical Information Manager S. C. Johnson, Mail Station 212 Racine, WI 53403-5011 Dear Mr. Fredrickson: This memo is in response to your request for information regarding the presence of California Proposition 65 listed chemicals in Vista's C-560 Slurry and Alfonic1412 A. Based on the analytical information currently available to Vista and our knowledge of the processes used to produce these products, we believe the following to be true. Vista C-560 Slurry contains no detectable quantities of Proposition 65 listed chemicals. Vista ALF0NIC1412-A does contain 1-4 dioxane in variable quantities. Product testing indicates the amount is typically less than 300 ppra but may exceed that concentration on occasion. This product also contains ethanol, but not as specifically listed by Proposition 65. Sincerely, Thomas G. Grumbles, C.I.H. Manager Environmental Affairs dlj VVV 000011733
