    摘要: An auxiliary for the soaking of hides and skins, which consists of a salt of the formula IM.sup.+ [O.sub.3 S--S--R].sup.- Iwhere R is an organic radical of 1 to 8 carbon atoms, which may carry one or more functional groups, and M.sup.+ is one equivalent of a cation, mixtures thereof with other conventional soaking auxiliaries, and processes for their use. Using the novel auxiliary avoids all toxicity hazards and odor nuisance, as well as avoiding oxidation losses, and achieves good loosening of the hair.

    摘要: Easily water-dispersible pulverulent formulations of disperse dyes are prepared by spray-drying a dye solution which comprises(a) one or more disperse dyes,(b) one or more water-soluble anionic dispersants,(c) from 0 to 20% by weight, based on (a+b+c+d), of other surfactants and(d) from 0 to 20% by weight, based on (a+b+c+d) of agents which serve as protective colloids (the proportion of (c+d) being at most 20% by weight).Suitable solvents (e) are formic acid, formamide, N-methylformamide, butyrolactone, ethylene glycol and propylene glycol, which may in addition contain up to 100% by weight, based on (e), of N,N-dimethylformamide or acetic acid or mixtures of these. The formulations obtained by the above process contain the dye in very fine dispersion.
