Mixtures of (A) from 55 to 65 mol % of erythro-dithiol of formula erythro-IV: and and their corresponding alkali metal salts and ammonium salts, are useful for treating animal hides.

Dithiol compositions and methods of treating animal hides using the same

Horny substances are removed from hides, pelts or skins of dead animals by treating the hides, pelts or skins in aqueous liquor with one or more compounds of the formula I or their corresponding alkali metal or alkaline earth metal salts or ammonium or phosphonium salts, the variables being defined as follows:

Method for removing horn substance from skins, pelts or furs

Tanning agents can be prepared by reacting at least one aldehyde of formula I, with at least one further identical or different aldehyde of formula I,  

Tanning agent and curing agent based on dialdehydes

The invention relates to a method for removing horn substances from animal skin. The method is characterized in that animal skins are treated in an aqueous bath containing between 0.05 and 5 wt. %, in relation to the weight of the salt, of at least one compound of general formula I or the corresponding alkali metallic salts or alkaline-earth metallic salts thereof or ammonium or phosphonium salts. The aqueous bath also comprises at least one compound which catalyses the hydrolysis of peptide compounds 

Method for removing horn substances from animal skin

Agents for the fatliquoring of, in particular, leathers and hides tanned in the absence of chromium comprise where Ris H or methyl, Ris methyl, ethyl or tert-butyl, The novel fatliquoring agents are used in leather production and/or leather treatment, and leather is produced and/or treated using aqueous dispersions of these fatliquoring agents.

Low-VOC stuffing agents, the use thereof in the production and/or treatment of leather and skins and corresponding production or treatment method

The present invention relates to C&#x2013;C-polymercaptopolyols as regulators in the free-radically initiated solution and precipitation polymerization of ethylenically unsaturated monomers.
