A process for pharma-grade sodium chloride

IPR Status & Details:

Patent filed

Application/Uses/Problem being addressed

The process is to manufacture pharm-grade salt. Main uses are in pharmaceutical industry. Pharmaceutical grade sodium chloride has many applications in injections, hemodialysis, oral rehydration salts (ORS), channeling agents/ osmotic agent, and dietary formulations etc.

Salient Technical Features including Competing Features/ Impact

  • It is a combination of chemical and physical method to separate the impurities to get the pharma-grade salt.
  • The process does not use expensive BaCl2 which is toxic in nature.
  • This process can be scaled-up as a continuous process without the necessity of time-consuming recrystallization step.
  • The production cost is less to sustain in the market.
  • Complies with the specifications of IP grade

    • TRL Level & Scale of Development:- TRL 4 TRL Reference

    Technology validated in lab scale at Kg level in CSIR-CSMCRI ESF/ pilot plant

    Business scope & opportunity (in terms of scale, cost, market etc.)

    Few companies have approached us for discussion regarding commercialization scope with capacity in the range ~250 ton/month. As there are no major manufacturer of pharmaceutical sodium chloride in India, indigenous process developed can fulfill both domestic need and offers export potential.

    Environmental Considerations

    The process is environmentally friendly. The solid by-product magnesium hydroxide along with other metal hydroxides can be used for derive other magnesia chemicals.
