short description:

The Replacement-type synthetic tanning agents are the core members of the synthetic tanning agent family and are hailed as “complements to plant tanning agents”. Unlike auxiliary-type synthetic tanning agents (which mainly function to disperse and homogenize) that only have dispersing and leveling effects, replacement-type synthetic tanning agents themselves possess significant tanning capabilities and can replace a portion or even most of the plant tanning agents (kautu) for leather tanning. At the same time, they can also give leather better light resistance, softness and filling properties.
