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.
Creating bio-based ingredients with multiple functions
Sugar chemistry creates bio-based ingredients for many purposes.
At Seppic, the application of this chemistry is built around a comprehensive knowledge in the field of sugars and the 12 principles of green chemistry. This involves an entire ecosystem, spanning sugar supply chains, understanding of the molecular structures and chemical properties of sugars and their derivatives, processing and analytical methods. It even extends to mastering the functionality and performance of the ingredients, whether foaming, wetting, hydrotope, solubilizing, detergent, emulsifying or biologically active, in the finished products.
Mastering the chemistry of sugars and the chemistry of polyols, has given rise to three main families of nonionic surfactants:
- Sorbitan esters,
- Alkyl PolyGlycosides (APG),
- Polyol PolyGlycosides (PPG).
