Abstract
THP and chrome are synergistic tanning agents. The combination of THP with small amounts of chrome and optionally non-ionic and/or cationic surfactants gives increased area yield and shrink temperature compared with THP, and reduced environmental impact compared with chrome. It is possible to combine degreasing, pre-tan and main tan in a single step.
