| titleOfInvention | Environmentally friendly chrome-tanning method |
| abstract | A method for tanning a hide wherein said method comprises treating a tannable hide with a tanning composition comprising from 25 to 75% by weight (wt. %) of at least one chromium(III) salt; from 5 to 70% by weight (wt. %) of at least one zeolite having the general formula (1): Mx/n [(AlO 2 )x(SiO 2 )y] wH 2 O, wherein M is an alkali metal cation, a bivalent cation, a trivalent cation or a mixture thereof, n is the valence of the cation, w is the number of water molecules per unit cell, y is a number from 0.8 to 50 and the ratio y to x is ranging from 0.7 to 100, treated with at least one acid selected from the group consisting of a monocarboxylic acid and a polycarboxyic acid; and from 1 to 70 wt. % of at least one aluminium(III) salt; wherein all wt. % are relative to the total weight of the composition (T). |
