Synthetic tannins
Auxiliary and replacement syntans with a low environmental impact
The Blancotan® product range includes replacement syntans for white leathers, soft leathers, and universal retanning, while auxiliary syntans are used for dispersing, neutralizing and pretanning leathers.
They are products made by the condensation of formaldehyde with the sulphonic acids of phenol and naphthalene.
Recently, Silvateam has invested significant resources developing products with a low environmental impact by reducing the content of phenol and free formaldehyde.
Synthetic tannins, Blancotan®, are used in tanneries as replacement syntans, to compliment the tanning action made by the natural tanning extracts. They are used as auxiliaries for pretanning, retanning and combined tanning and as dispersing agents for vegetable tannins and dyestuffs.
