Title of the Innovation: Halogen Scavenger Grade and Pharmaceutical Grade Synthetic Hydrotalcite
Brief About Innovation
This lead free environmentally friendly halogen scavenger type hydrotalcite can be prepared from three industrial wastes such as aluminum chloride waste- generated, bittern containing magnesium compounds generated in solar salt work, and ammonium carbonate solution generated in organic pigment industries.
Advantages:
This environmentally friendly material is halogen scavengers in heavy-metal free stabilizer systems. Because of its anionic exchange capacity and the ability to capture organic and inorganic anions makes hydrotalcite almost unique as inorganic material. Hydrotalcite increases the bioavailability of the active ingredient, especially of poorly soluble substance. These special features enable a huge number of applications with high added-value in several fields.
Application:
SHT finds application in pharmaceutical industry as an antacid. SHT has also replaced heavy metal based heat stabilizers for PVC. SHT like compounds are imported under the trade name like DHT-4A, L-55R-II and Alcamizer. They are used as halogen scavenger in plastic processes such as the production of polypropylene. Other applications include base or Support catalysts, adsorbent for wastewater treatment, ion exchangers, drug releasers, anticorrosive materials as well as a wide range of environmental applications. The global demand of synthetic hydrotalcite is more than 75000 tons. Its demand is expected to grow further by 2020 to replace lead stabilizer due to regulatory norms in developed countries. In India most of the material( SHT) is being imported hitherto.
