  • Publication number: 20220186048
    Abstract: Rhamnolipids and/or sophorolipids can be used in coating compositions for improvement of the speed of wetting of pulverulent formulation constituents in such compositions, which leads to a reduction in dust nuisance during incorporation thereof and to the increase in occupational safety in the production of coating compositions. Rhamnolipids and/or sophorolipids can also be used in coating compositions for obtaining improved homogeneous colour appearance of the dry paint film with regard to difference in hue, ascertained from the delta E and visual assessment.

  • Patent number: 9956433
    Abstract: The present invention relates to foamable oil-in-water emulsions containing: A) one or more emulsifiers, at least one of which is a non-ionic emulsifier, B) one or more cotensides, C) one or more oils, D) optionally, one or more polar solubilizers, E) optionally, auxiliary and additive substances, F) one or more surfactants, G) water, H) optionally, water-soluble substances, provided that the water content of the emulsion is ?70% by weight and the concentration of surfactant(s) F) is from 0.01 to less than 10% by weight, each based on the entire emulsion. The invention further relates to a method for producing the oil-water emulsions according to the invention, to foams obtained from these oil-water emulsions, to a method for producing the foams, and to the application of the oil-water emulsions according to the invention and to the foams produced therefrom.

  • Patent number: 9380916
    Abstract: The invention relates to a dispenser system with a housing, into which a reservoir cartridge is inserted, which is formed by a reservoir container and a distribution device. Housing comprises an actuation device which acts on distribution device in such a way that a pressure on the actuation device delivers a portion of the medium on the distribution device. The known dispenser systems have the drawback that an individual dispenser is required depending on the medium. According to the invention, in order to create an identical part dispenser system, a connection element compensating for the different geometries of distribution device is connected to distribution device. Moreover, actuation device comprises at different levels pressure-exerting faces, which cooperate with pressure-receiving faces of distribution device, wherein different faces engage with one another depending on employed reservoir cartridge.
