Description

When vegetable tannins are extracted, other water-soluble components also dissolve into the tanning solutions. These are called nontannins or nontans. These additional components can be beneficial to the tanning process. Some nontans add color (Brasilin, fisetin, etc. ) while others, such as sugars or starches, plump the Leather. Organic acids and salts can also aid in the tanning process.
