  • CONTINUOUS RECYCLING OF WASH WATER WITH FLOCCULATION DEVICE AND PROCESS
    Publication number: 20180290078
    Abstract: Device and process for continuous recycling of wash water, so that water consumption is reduced in conventional personal wash, especially in a shower. The device comprises a surfactant detector (2), a flocculation tank (4), a water tank (5) for cleaned water and a bypass valve (3), wherein the flowpath shifts directly to the water tank (5) by means of the valve (3) bypassing the flocculation tank (4), in the absence of a surfactant in the flowpath.

  • PERSONAL CARE COMPOSITION COMPRISING AN INORGANIC PIGMENT AND A ORGANIC DYE
    Publication number: 20130149365
    Abstract: The invention relates to personal care compositions for improved skin appearance especially for dark skinned consumers. The personal care composition of the present invention comprises a selective combination of an inorganic pigment particle that has a specific light scattering property (reflection of incident light predominantly in the red region) and an organic dye that has a specific light absorption property (absorption of incident light predominantly in the blue region). This selective combination provides for the highly pleasing even skin appearance.
