    • Sulfoxides of alkylthiomethylphenols of the formula I ##STR1## in which R.sub.1 is hydrogen, C.sub.1 -C.sub.20 alkyl, C.sub.2 -C.sub.18 alkenyl, C.sub.5 -C.sub.7 cycloalkyl, C.sub.5 -C.sub.7 cycloalkenyl, phenyl or C.sub.7 -C.sub.9 phenylalkyl, R.sub.2 is hydrogen, C.sub.1 -C.sub.20 alkyl, C.sub.2 -C.sub.18 alkenyl, C.sub.5 -C.sub.7 cycloalkyl, C.sub.5 -C.sub.7 cycloalkenyl, phenyl, C.sub.7 -C.sub.9 phenylalkyl or a radical --CH.sub.2 --SO--R.sub.5, in which R.sub.5 is C.sub.8 -C.sub.20 alkyl which may be interrupted by --O--, --S-- or --SO-- groups, mono- or dihydroxy-substituted C.sub.2 -C.sub.12 alkyl, phenyl, benzyl, --(CH.sub.2).sub.n COOR.sub.6 or --CH(CH.sub.3)COOR.sub.6, in which R.sub.6 is C.sub.1 -C.sub.20 alkyl and n is 1 or 2, R.sub.3 is hydrogen or a group --CH.sub.2 --SO--R.sub.5, in which R.sub.5 is as defined above, and R.sub.4 has the same meanings as R.sub.2 , with the proviso that only one of the radicals R.sub.2, R.sub.3 or R.sub.4 is the group --CH.sub.2 --SO--R.sub.5 and that, if R.sub.4 is --CH.sub.2 --SO--R.sub.5 and R.sub.1 and R.sub.2 are simultaneously tert-butyl or tert-amyl, R.sub.5 is not C.sub.8 -C.sub.14 alkyl, or mixtures of these compounds with the corresponding non-oxidised compounds are suitable for stabilising organic materials which are sensitive to oxidative, thermal and/or light-induced degradation.
