Potassium Sodium Tartrate
What Is It?
Tartaric Acid is a white crystalline organic acid. It occurs naturally in many plants, particularly grapes and tamarinds. Salts of Tartaric Acid are called Tartrates. These salts include Calcium Tartrate, Potassium Tartrate, Potassium Sodium Tartrate and Disodium Tartrate. In cosmetics and personal care products, these ingredients are used in soaps, skin care products, suntan products and hair care products.
Why Is It Used?
Tartaric Acid and its salts are used as A measurement of the acidity or basicity of a substance. pH is the negative logarithm (base 10) of the concentration of hydrogen ions in solution. Water has a concentration of hydrogen ions of 1.0 x 10-7, and thus has a pH of 7. A pH of 7 is considered neutral, a pH lower than 7 is considered acidic, and a pH higher than 7 is considered basic. adjusters in cosmetics and personal care products. pH Adjusters are used to control the pH of finished cosmetic products.
Tartaric Acid is an organic carboxylic acid salt. Tartaric acid occurs in many fruits. It is widely used in bakery products, gelatin desserts and in soft drinks.
The Food and Drug Administration (FDA) has reviewed the safety of Potassium Sodium Tartrate and has affirmed its status as Generally Recognized as Safe (“GRAS” is an acronym for the phrase Generally Recognized As Safe. Under sections 201(s) and 409 of the Federal Food, Drug, and Cosmetic Act (the Act), any substance that is intentionally added to food is a food additive, that is subject to premarket review and approval by FDA, unless the substance is generally recognized, among qualified experts, as having been adequately shown to be safe under the conditions of its intended use, or unless the use of the substance is otherwise excluded from the definition of a food additive.) as a direct food substance. FDA has approved the use of Tartaric Acid and Potassium Sodium Tartrate in Over-the-Counter (OTC) antacid drug products. The Cosmetic Ingredient Review (CIR) was established in 1976 as an independent safety review program for cosmetic ingredients. The CIR Expert Panel consists of independent experts in dermatology, toxicology, pharmacolgy and veterinary medicine. The CIR includes participation by the U.S. Food & Drug Administration and the Consumer Federation of America. (CIR) has deferred evaluation of these ingredients because the safety has been assessed by FDA. This deferral of review is according to the provisions of the CIR Procedures.
