The optical brightener, Tinopal LPW, was subjected to different pHs, temperatures, and to ultraviolet (UV) radiation. Tinopal LPW was stable at pHs ranging from 3.0 to 10.4, at temperatures of 121 for 5 min, and at UV exposures (254, 302, and 360 nm) for periods up to 7 d. These treatments did not adversely affect the activity of Tinopal LPW as an enhancer for the gypsy moth nuclear polyhedrosis virus.
