| Applications | Uses: A conditionally essential amino acid, Used as a nutritional supplement, [Merck Index] Used in biochemical research, pharmaceuticals, and as a wetting agent, [NTP], Derivatives of taurine, especially fatty acid derivatives, are important wetting, washing, and dispersion agents in body and household cleaning agents, and also in textile processing., Biochemical research, wetting agents, Nutritional supplement, Cosmetic compositions, For more Uses (Complete) data for Taurine (10 total), please visit the HSDB record page., Use (kg, approx.) in Germany (2009): >750, Consumption (g per capita, approx.) in Germany (2009): 0.00916, Calculated removal (%): 75.1, Use Classification: EPA Safer Chemical Functional Use Classes -> Processing Aids and Additives, Safer Chemical Classes -> Green half-circle - The chemical is expected to be of low concern, Flavouring Agent -> FLAVOURING_AGENT -> JECFA Functional Classes, Flavoring Agents -> JECFA Flavorings Index, Cosmetics -> Buffering, Industry Uses: Not Known or Reasonably Ascertainable, Methods of Manufacturing: Taurine is synthesised starting from ethylene oxide and sodium bisulphite. Subsequently, liquid ammonia and sulphuric acid are added. The product is then decolorised, purified, crystallised, centrifuged, dried, sieved and blended with the carrier to obtain the additive., Ethyleneimine reacts rapidly with sulfurous acid to give taurine in high yield., Impurities: Taurine is a white crystalline powder that is almost odourless but with a slightly acidic taste. It contains by specification at least 98.0 % taurine in dried substance. Analysis of five batches of the active substance showed an average content of 99.5 +, - 0.1 % taurine and a loss on drying of 0.07 +, - 0.01 %.11 The final additive may be formulated by adding a maximum 0.8 % of an anti-caking agent (SiO2). Three batches of the additive were analysed for impurities, one batch with six replicate samples and another batch with three replicate samples. In all batches, sulphated ash was < 0.06 % (in one batch residue on ignition 0.06 %), chloride < 0.01 %, sulphate < 0.01 %, ammonium salt < 0.02 %, related substances < 0.2 %, heavy metals (expressed as lead) < 10 mg, kg and arsenic < 1.0 mg, kg (two batches)., Formulations, Preparations: Diabetic Support Formula Tablets: Taurine 50 mg, and minerals, vitamins, herbs, Diabetiks Tablets: Taurine 375 mg, and vitamins, minerals, herb extracts, Enfamil Kindercal Liquid with Fiber: Taurine 15 mg, fiber, Enfamil Kindercal Liquid: Taurine 15 mg, with vitamins and minerals, U.S. Production: 2023: 35, 273 lb, 2021: 35, 2020: 35, 274 lb, Production volumes for non-confidential chemicals reported under the Inventory Update Rule.[Table#8141], Production volume for non-confidential chemicals reported under the 2006 Inventory Update Rule. Chemical: Ethanesulfonic acid, 2-amino-. Aggregated National Production Volume: < 500, 000 pounds., General Manufacturing Information: Miscellaneous Manufacturing, Ethanesulfonic acid, 2-amino-: ACTIVE, Dietary taurine mainly comes from animal food. Taurine is present in very low levels in plant foods. Taurine is found in seaweeds., Taurine is the only known naturally occurring sulfonic acid. The material is an essential amino acid for cats and is used extensively by Ralston Purina Company as a food supplement in cat food manufacture. Approximately 5, 000-6, 000 tons of taurine (synthetic and natural) were produced in 1993, 50% for pet food manufacture, 50% in pharmaceutical applications., Taurine and D-glucurono-gamma-lactone are constituents of the so-called energy drinks, but they also occur at much lower levels as natural ingredients in food, and they are also normal human metabolites., Taurine occurs naturally in food, especially in seafood and meat, and it is a normal metabolite in humans. It is a metabolic product of sulphur-containing amino acids, and it is mainly biosynthesised from cysteine in the liver., ...taurine used in "energy" drinks complies with US Pharmacopoeia specifications (US Pharmacopeia, 2005). Purity is not less than 98.5 %. |
