Abstract
A method of preparing an aqueous composition for treating leather comprises adding a predetermined amount of a solid particulate leather treatment composition directly into a predetermined amount of water in a vessel at a tannery; and dissolving or dispersing said solid particulate composition in said water. The solid particulate composition comprises 0.1 wt % or more based on the total weight of said particulate composition of a particulate hygroscopic material. The solid particulate composition is non-dusting in humid atmospheres.
Claims7
A method of rendering a solid, dusting leather treatment composition non-dusting, comprising the step of admixing a particulate solid, dusting leather treatment composition with a particulate hygroscopic material to form an admix, wherein said admix comprises at least 0.1 weight % particulate hygroscopic material.
A method of preparing an aqueous composition for treating leather, comprising the steps of:
- a) preparing a solid particulate leather treatment composition comprising a particulate solid, dusting leather treatment composition and at least 0.1 weight % particulate hygroscopic material, based on weight of said solid particulate leather treatment composition;
- and
- b) dissolving or dispersing said solid particulate leather treatment composition in an aqueous diluent or carrier.
A method of treating leather comprising the steps of:
- a) preparing a solid particulate leather treatment composition comprising a particulate solid, dusting leather treatment composition and at least 0.1 weight % particulate hygroscopic material, based on weight of said solid particulate composition;
- b) dissolving or dispersing said solid particulate composition to an aqueous diluent or carrier to provide an aqueous composition for treating leather;
- and
- c) contacting said aqueous composition for treating leather with leather.
