FIELD: chemistry.
SUBSTANCE: inventions relate to water compositions, containing at least one compound, which has carbamoylsulphonate groups, and modified polyol, method for obtaining, as well as application as tanning substance or substance for pre-tanning. Water composition for tanning skins and furs contains at least one compound, which has carbamoylsulphonate groups, and at least one non-ionic containing ester groups alkoxylated polyol with value of hydrophilic-lipophilic balance at least 13 and/or alkylglycoside and carboxylic acid, selected from citric acid, lactic acid and/or tartaric acid, with products of interaction from organic polyisocyanates and bisulphite and/or disulphite being used as compounds, possessing carbamoylsulphonate groups. Method for tanning skins or furs. Method for obtaining leather and/or fur. Compounds, possessing carbamoylsulphonate groups.
EFFECT: inventions make it possible to obtain compositions of tanning substances with improved storage stability.
