PROBLEM TO BE SOLVED: To provide a stabilizer for crude emulsion rubber, synthetic latex and natural rubber latex. SOLUTION: This invention includes a composition comprising (a) a material such as crude emulsion rubber, synthetic latex and natural rubber latex that are decomposed by oxidation, thermally, kinetically and/or photo induction and (b) one or more of compounds expressed by the formula I (R1 is an 8-20C alkyl): and optionally (c) one or more of compounds expressed by the formula II. (R2 is an 8-12C alkyl; R3 is H, a 1-12C alkyl, cyclohexyl, 1-methylcyclohexyl, benzyl,α-methylbenzyl,α,α-dimethylbenzyl or -CH2 -S- R2 group; R4 is a 1-12C alkyl, benzyl,α-methylbenzyl,α,α-dimethylbenzyl or -CH2 -S- R2 group; and R5 is H or methyl).
