:''Not to be confused with Calgon Carbon'' Calgon is a brand registered trademark of water softener, and bath and beauty products. The original product consisted of powdered sodium hexametaphosphate (amorphous sodium polyphospate), which in water would complex with ambient calcium ion and certain other cations, preventing formation of unwanted salts and interference by those cations with the actions of soap or other detergents. Its name was a portmanteau derived from the phrase "calcium gone".〔(Walker, Andrea K. "Calgon, take me away...again," ''The Baltimore Sun'', Tuesday, June 22, 2010. )〕 Originally promoted for general use in bathing and cleaning, it gave rise to derivative products which have diverged from the original composition. Today, Calgon water softener contains the active ingredients zeolite and polycarboxylate, which are less problematic in wastewater treatment than phosphates. The Calgon water softener was first introduced to the market in 1933 by Calgon, Inc. of Pittsburgh, Pennsylvania. Calgon, Inc. was acquired by Merck in 1968 and later broken up and sold off. Today, the brand is owned by Reckitt Benckiser for use in Europe as a water softener, and in the United States by Ilex Consumer Products Group as a bath and beauty product. == Companies == The brands have their origin in Calgon, Inc. of Pittsburgh, Pennsylvania, which first put Calgon water softener on the market in 1933.〔Trademark registration of "Calgon", (U.S. Patent and Trademark Office ).〕 It was acquired by Merck in 1968 and later broken up and sold off.
