Abstract

A tanning composition comprising: a) aluminium hydroxychloride, b) a product of condensation between dicyandiamide and formaldehyde, c) an organic stabilizer of an acid nature, d) polyacrylic acid, polymethacrylic acid or a copolymer of acrylic acid and methacrylic acid, makes it possible to perform independent tanning, pretanning or retanning treatments for hides or to stably fix high levels of chromium or tannins in the animal skins in conventional tanning treatments and to substantially exhaust the chromium or tannins contained in the tanning bath.
