This invention relates to shaped, non-dusting, non-sticking, free-flowing masticating agents based on 2,2'-dibenzoamidodiphenyl disulphide and paraffins having a solidification point in the range from 50.degree. to 85.degree. C., a needle penetration of 8 to 25 in 1/10 mm, a viscosity of 2 to 10 mm.sup.2 /s. The masticating agents according to the invention are used to reduce the viscosity of rubbers containing double bonds and are customarily used in quantities of 0.01 to 3 parts by weight.
