A technology to support formulators
Thickening polymers are among the most-used ingredients in formulations. Because of their ability to govern rheological behavior, they are essential ingredients for controlling usage performance and ensuring users have a positive perception of the products.
At Seppic, we use two main polymerization technologies: inverse emulsion polymerization and precipitation polymerization.
Inverse emulsion polymerizationInverse emulsion polymerization is an effective manufacturing technology for producing high-performance liquid thickeners. Pre-neutralized and ready to use, these polymers can be used cold during the formulation of end products.
Inverse emulsion polymerization technology
Inverse emulsion polymerization technology is a process of radical polymerization which consists of polymerizing ethylenic and hydrophilic monomers, which are soluble in water droplets, dispersed in an oily phase and stabilized by a low HLB (hydro lipid balance) emulsifier system.
This technology leads to the formation of high molecular weight polymers trapped in water droplets dispersed in a water-in-oil emulsion. Depending on the targeted properties, the structure of the polymer can be adapted through the choice of the monomers and the crosslinking system.
