Chitin (pronounced kite-in) came into being in the 1970's when the EPA ordered fishing companies to stop dumping the shells of crabs and lobsters back into the ocean. Researchers discovered that the chitin contained in the shells had properties that could be applicable in a variety of industrial uses. Similar to cellulose, chitin is a naturally occurring polymer. It is also the only naturally occurring polyelectrolyte.

One manufacturer, Vanson developed a product known as SeaKlear, as an almost revolutionary pool chemical. All natural, the reps were known for drinking small amounts of their own product at trade shows to show how harmless their Chitin-based product was. SeaKlear products grew into a wide variety of pool and spa chemicals. Recently purchased by HaloSource, Vanson's original formulation is widely distributed.
