SYNTHESIS
http://www.univ-toulouse.fr
Synthesising biocompatible products is a major stake for cosmetic and biomedical industries.
Pierre Monsan’s team in Toulouse (LISBP-INSA) has developed new enzymes transforming sugar
called glucan-saccharases. One specific enzyme (DSR-S) allows synthesising from saccharose a
glucose polymer called dextran, and obtaining in one step dextrans with controlled molecular weight
and various structures (types of bond, size).
These molecules of dextran, produced through an environmentally-friendly process, can be used for a
large range of applications in cosmetics, biomedical and chemical industries: proven biocompatibility,
controllable viscosity which is a key factor for cosmetic formulation, active ingredient for water
retention, stimulation of cell growth as a major property for tissue regeneration, exclusion
chromatography, biopolymer substituting synthesised polymer.
A partner is sought to contribute to the development of
this technology in the fields of cosmetics and chemistry.
