  • Patent number: 9663661
    Abstract: The present invention relates to an effect pigment comprising as a substrate a glass flake with a coating, said coating comprising at least one layer of at least one high refractive material, said material having a refractive index of at least 1.8, and/or at least one layer of at least one semitransparent metallic material, wherein said glass flakes comprising the following composition: 65-75 wt.-% silicon oxide, preferably SiO2 2-9 wt.-% aluminum oxide, preferably AI2O3 0.0-5 wt.-% calcium oxide, preferably CaO 5-12 wt.-% sodium oxide, preferably Na2O 8-15 wt.-% boron oxide, preferably B2O3 0.1-5 wt.-% titanium oxide, preferably TiO2 0.0-5 wt.-% zirconium oxide, preferably ZrO2 based on the weight of said glass flakes. The invention relates also to a method for producing the effect pigments as well as to the use of said effect pigments. The invention further relates to coating formulations based on the effect pigments.

  • Publication number: 20100135916
    Abstract: Water in silicone emulsions, methods for preparing the emulsions, and personal care products containing the emulsions are disclosed. The silicone phase of the water in silicone emulsions contains an emollient, a silicone elastomer containing a hydrophilic group, and an optional nonionic surfactant. The aqueous phase contains an anionic surfactant at such a concentration to provide a weight ratio of the silicone elastomer to anionic surfactant ranging from 60/1 to 1/1 in the water in silicone emulsion. The resulting water in silicone emulsions can be used in a variety of personal care, household and health care formulations, and in particular for sprayable lotions.
