Technical Information


Formic GREEN is a bio-degradable and eco-friendly, non-flammable product specially developed for the leather industry, as a dye-fixing agent and for
regulating Ph during the tanning process. When compared to formic acid (which is an non-eco-friendly, toxic and difficult to handle product currently
used as a dye fixing agent), Formic GREEN does not give the same harshness (compared to formic acid) nor does it affect in any adverse manner the
polymer / fiber structure or luster of the leather during tanning.

Formic GREEN also reduces the consumption of auxiliary chemicals, dyes and also effectively fixes the dyes onto the leather, thereby reducing the
effective cost of production. Being a non-polluting and eco-friendly product, using Formic GREEN reduces the effluent treatment cost as it does not
damage the membrane of the effluent treatment plant compared to formic acid.

For Cow and buff wet blue production:
The advantage of using Formic GREEN in the wet blue stage is that:
It quickens the pickling process.
It gives uniform chrome tannage, fast penetration and smooth grains.
It avoids drawn grains and wrinkles in the wet blue stage.
It gives good bleaching and brilliance in the wet blue.
Complete exhaustion of the syntans and fat liquors.
It deeply penetrates the chrome and float is cleared


1- Formic GREEN is a user and eco friendly and cost effective product.
2- It’s specially formulated as non-polluting product for leather tanneries.
3- It’s easily miscible with water.
4- It ensures higher dye depth without affecting the grain surface.
5- It’s compact for pickling, fatliquoring and dye-fixing
6- It gives a better touch, smoothness, good penetration and shade intensives.
7- It’s used in same percentage as Formic Acid and in some cases user can
even reduce rate of consumption.
