Modified larch tannin was prepared by grafting copolymerization and sulfoalkylation, and successfully used as retanning agent, possessing good water solubility and enhanced penetration rate.
Jim Haywood, an atmospheric scientist at the University of Exeter, UK, says that hydrochloric acid solubility in the wake of fires hasn't been investigated previously.
So for example, you can generate many different types of new molecules, but you can add constraints like have better toxicity, solubility, etc. It can allow you to do that simultaneously.
