  • Patent number: 7838613
    Abstract: The invention relates to polyorganosiloxane monocomponent compounds (POS) which are stable when stored without humidity and crosslinking into elastomer in the presence of water. The inventive compounds comprise at least one type of crosslinkable linear polyorganosiloxane (POS), a mineral filler and a crosslinking catalyst of formula (I) which provides said compound with an excellent compromise between cross linking kinetics and a storage stability (i.e. more than 6 months).

  • Patent number: 7825206
    Abstract: The invention provides a process for preparing SiOC-bonded polyorganosiloxanes by reacting, by processes known per se, hydroxyl-containing compounds with a stoichiometric excess of polyorganosiloxanes which contain —Si(H) units and are of the general formula (I) in the presence of one or more element compounds of main group III and/or of transition group 3 as a catalyst, wherein the reaction, on completion of conversion of the compounds containing hydroxyl groups, is continued until no further ?Si—H groups are detectable by gas volumetric means, and also the compounds prepared in this way and their use.

  • Patent number: 7790813
    Abstract: The present invention relates to a series of crosslinked silicone polymers that by virtue of the nature of the dimol alcohol undecylenic acid ester based crosslinker, have unique solubility and properties. These include improved tolerance for oily materials and improved skin feel. These polymers find use in personal care applications like pigmented products. In the personal care arena, solid products that do not experience syneresis are important. Syneresis is a condition that exists in a solid product that causes a liquid that is incompatible to ooze out, which is cosmetically unacceptable.
