Cationic bio-charges from marin sources

The catiomerc project aims to develop 100% natural cationic bio-charges for industrial applications in the field of cosmetic as an alternative to conventional petrochemical surfactants. These bio-charges are from the alliance of a section of chitin and / or its derivatives and clay.

The CATIOMERC project aims to develop 100% natural cationic bio-charges for industrial applications in the field of cosmetic as an alternative to conventional petrochemical surfactants. These bio-charges are from the alliance of a section of chitin and / or its derivatives and clay. They make it possible to stabilize an emulsion or thicken an aqueous solution. From a biochemical point of view, the cationic charges can rebalance the anionic charges that accumulate on the surface of our skin and our appendages. Indeed, the cationic charges have a great affinity with the keratin in the skin or hair that is negatively charged. This results in the formation of a smooth film on the surface of the skin and especially the hair. Industrial innovation is created with an innovative production with low environmental impact, the reactive extrusion. This will allow the industrialization of eco-products with high added value, chitin, providing an added-value for the French and Canadian marine biomass. The process of reactive extrusion will also control production cost to ensure an economically viable processes versus conventional quaternization alternatives. To our knowledge, there is no emulsifier from a cationic bio-charge lamellar hybrid organic / inorganic directly produced from 100% natural raw materials. Nevertheless, in the literature, we can find several studies on the feasibility of intercalation between a lamellar clay and chitosan (Chem. Mater, 2003, 15 (20) 3774-3780;. Journal of Applied Polymer Science 2006, 99, 1684-1691, Chitin and Chitosan, Biopolymer From the application, G Crini, University of Franche-Counted Press, 2009). Therefore, the positioning of the project in relation to competitors must consider other aspects to strengthen this competitive advantage. It is targeted to optimize the production process loads to ensure quality, reduce the cost of producing bio-charges and anticipate the production of large volumes. This is the challenge posed by the development of production processes by reactive extrusion. This is a major point, vis-à-vis conventional organo-modified clays (Cloisites family and Claytones particular) currently on the market, which are produced by companies with large production capacity (SOUTHERN CLAYS , ROCKWOOD, Nanocor ...) and where price competitiveness is strongly related to volumes. The breakthrough solution (game changer) proposed for this new material, is based on the replacement of existing manufacturing processes in batch reactors by a continuous reactive extrusion process. The extrusion method involves passing one or preferably several products through different compression modules under the action of single-screw or twin-screw extruder with or without heat input. The extrusion does not typically imply a thermomechanical phenomena. If chemical reactions are voluntarily induced, it is called reactive extrusion. The solids are fed through a hopper equipped with a metering pump for the flow adjustment. Liquid products are generally injected at unfilled areas, via an external infusion pump. The main advantage of reactive extrusion resides in the unique ability of extruders to catalyze chemical reactions on products with high viscosity, greatly limiting the amount of solvent used. This process is considered, rightly, as a powerful tool and quite suitable for a green chemistry approach and offers significant savings in terms of water and energy. These savings result in a lower impact on the environment, which allows for an eco-design approach.
