Acid-free paper Acid-free paper Acid-free paper is paper that if infused in water yields a neutral or basic pH (7 or slightly greater). It can be made from any cellulose fiber as long as the active acid pulp is eliminated during processing. It is also lignin- and sulfur-free. Acid-free paper addresses the problem of preserving documents and artwork for long periods. Paper made from wood-based pulp that has not had its lignin removed turns yellow, becomes brittle, and deteriorates over time. When exposed to light and/or heat, the molecules in the acidic paper will break down even faster. Acidic wood-pulp paper became
Ortek Therapeutics Ortek Therapeutics Ortek Therapeutics, Inc. is a private healthcare company based in Roslyn Heights, New York which specializes in researching and commercializing oral care products. It was founded in 1998. To date, Ortek's commercial success is based on the company's patented AlkaGen Technology (an arginine bicarbonate/calcium carbonate complex). The Company plans on incorporating this technology in their sugarless soft chews, BasicBites. Arginine is a common amino acid found in many foods and is also naturally found in saliva. On tooth surfaces, arginine is broken down by certain pH rising plaque bacteria to acid-neutralizing alkali. This results in a sustained neutral
