Disclosed are biodegradable core-shell microcapsule compositions composed of microcapsules having a wall formed by self-condensation of an isocyanate in the presence of a denatured pea protein as dispersant. Also disclosed are consumer products containing such a core-shell microcapsule composition and methods for producing core-shell microcapsule compositions.

A method of increasing anion ion exchange capacity by using certain multivalent acids or salts. Also, a method for modifying pH working range of weakly basic anion ion exchangers for the purpose of metal extraction or other ion exchange processes using multivalent inorganic or organic acids or salts or esters or oxides. Media can be altered or a new media developed that will have a substantially higher loading capacity, able to work at much higher pH range, easily able to remove metal, able to quickly regenerate, and does not have all the environmental liabilities of ion exchange media in use today.
