This proposal forms part of an ongoing project concerning interpenetrating network gels of starch and cellulose being developed towards applications in personal care and agrochemicals based on the interests of our industrial partners. Addition of soluble starch polymers to partially oxidised cellulose (oxcel) suspensions creates gels with increased viscosities over single component suspensions. We aim to build on our previous studies of oxcel gels by determining changes in gel network structure and properties when soluble starch, anionic surfactant and salts (which are known to gel the oxcel fibrils), are added. Selective deuteration will enable us to highlight oxcel gel structures, the starch network and the location of starch and anionic surfactant within the oxcel network. Structural results will be combined with rheological measurements to improve formulation using these materials.
