text: A favorable synergistic effect between hydroxybenzophenone or hydroxyphenylbenzotriazole type ultraviolet absorbers and thiols or sodium hypophosphite has been reported (Davidson et al. 1995; Trichet et al. 1996) and ascribed to the regeneration of the UV absorber by reduction (Noutary et al. 1994, Gugumus 1993), whereas others have reported that the improved stability is not due to a regeneration mechanism (Cook and Ragauskas 1997).
