The reserve acidity in this powder gives mellowing effect and promotes the fixation of condensed type tannins. Blended with catechol tannins, this imparts light colour, fullness, plumpness and firmness to leather. This powder does not oxidize when exposed to sunlight and gives a protective coating to increase the colour fastness of the condensed tannins. It is more significant in making sole leather blended with mimosa extract. It is used in pit and drum processing in the manufacture of e.I. Kips, buff calf and skin. It protects from oxidation and aids better fixation of condensed tannins. By blending with syntans, it is useful for retanning, particularly shrunken grain upper leathers. It is used in boiler water treatment compound and as a mud-thinning agent in oil drilling. 25 kg bag
