Modified zeolites as sustainable alternatives to traditional tanning chemistries This research article, published in the journal Green Chemistry, gives a deeper insight on modified zeolites as a versatile and sustainable means to move away from established tanning methods. What chemicals are used to tan leather? The most used chemical to tan leather is chromium III. Other chemicals used in tanning are aldehyde, vegetable tannins and zeolites. Is Zeology tanned leather more biodegradable than chrome tanned leather? Zeology tanned leather biodegrades quicker than the traditional tanning technologies. Phenolic monomers in aromatic syntans: the influence on leather Aromatic syntans are widely used in the (re)tanning of leathers. Phenolic monomers such as phenol, phenolsulfonic acid, bisphenol S, and bisphenol F are common compounds in aromatic syntans.
