The Société Chimique ALKIMIA, has been founded on September 26th, 1972 and started production in 1976 with a design capacity of 30 000 tons per year (tpy) of technical Sodium Tripolyphosphate (STPP; Na5P3O10).

After having increased the production capacity of sodium tripolyphosphate to 140,000 tpa and renovated its facilities, the Société Chimique ALKIMIA has now reached a stage of development which allows it to: produce and market other chemicals

Thus, it has been decided in Novembre 2009 to create ALKIMIA-Packaging Ltd subsidiary at 100%, for packaging and marketing of soda ash (Na2CO3) in Tunisia and North Africa. See attached Technical data sheet

Sodium Tripolyphosphate STPP

Detergent grade

The STPP powder is mainly used in the preparation of detergent slurry. Molecular structure of STPP is presented in two different forms called phase 1 and phase 2. The rate of composition of the STPP in phase 1 and phase 2 gives various rate of hydration.

In general, for each technique of slurry preparation, there is a specific quality of STPP.

For modern installations of detergent, with fast and powerful mixers, the stpp high rate of hydration is recommended.

It permits reduction time in the preparation of the slurry, saving energy in the heating and the drying of the slurry and a better quality of detergent powder.

  • Rapid Hydration
  • Average Hydration
  • Slow Hydration
