Dr. Wayne Jaeschke Stauffer [stamped, MAR 6 1980] Benzyl peroxide Dear Wayne As you know this compound is widely used for acne. My 15 year old son is using it now. Can you locate any tests of it re carcinogenicity? (cf. attached.) I believe peroxides are also widely used as starters for polymerizations . . . . . Dick Young passed on your offer of staff help on similar (potentially more important!) questions. and Harry Williams just contacted me. Yours, Joshua.
