Organofunctional polyorganosiloxanes, their use in cosmetic compositions, method for treating amino acid based substrates with organofunctional polyorganosiloxanes, compositions comprising the organofunctional polyorganosiloxanes useful for hair straigthening and shaping as well as hair coloration and hair color retention.


The invention relates to a method for cleaving silicon-silicon bindings and/or silicon-chlorine bindings in monosilanes, polysilanes, and/or oligosilanes. According to the invention, the monosilane, polysilane, and/or oligosilane is dissolved or suspended in an ether or in an ether-hydrochloric acid solution. Said method is used for example for preparing halogenated oligosilanes from halogenated polysilanes and for preparing siloxanes from organochlorosilanes and chlorinated monosilanes. Said method is particularly simple to carry out and as a result is economical.

The CO-PILOT project addresses the field of nanocomposites which has witnessed remarkable progress (compound annual growth rate of 18%) in recent years with many different types of nanocomposites exhibiting radically enhanced properties for a wide range of industrial applications. The CO-PILOT project aims to develop an open access infrastructure for SMEs interested in the production of high quality (multi-)functional nanocomposites on a pilot scale. In CO-PILOT this infrastructure will be prepared for access (open acess) by SMEs beyond the project. It will be able to produce typically 20 to 100 kg nanocomposite product, characterize it and validate its performance. This is sufficient to make management decisions to progress to the next step of new nanocomposite product development. CO-PILOT aims to set new standards for high-quality nanoparticle production with the assistance of in-line nanoparticle dispersion quality monitoring. CO-PILOT chooses to develop a centrifuge module to address the adequate and automated down-stream processing of the nanoparticle dispersions. CO-PILOT will test and validate the pilot line infrastructure. Based on the consultation of SME nanocomposite producers, CO-PILOT has chosen the following range of industrial nanocomposite applications : - flame and smoke inhibiting polymer materials (layered double hydroxides) - acid scavenging used as anti-corrosion and in polymer stabilisation (layered hydroxides) - heat isolating plastics (hollow/porous silica) - light-weight flame inhibiting composites (layered hydroxides combined with hollow/porous silica) - UV protective polymer coatings (zinc oxide, titanium dioxide) - high refractive index, visually transparent polymer (titanium dioxide) - low-refractive index polymer (hollow/porous silica) - anti-glare polymer coatings (hollow/porous silica) - magnetic recoverable catalyst nano-composite beads (magnetite).
