    摘要： This invention relates to a particulate fluorescer and a process for preparing the same. More particularly the present invention relates to a bipolar particulate fluorescer for use in laundry detergent composition, fabric conditioner and cosmetic compositions and a process for making the same. In view of the foregoing, it is an object of the present invention to provide a fluorescer with improved retention to the fabric so that larger amounts of fluorescer will be available even after rinsing. It is yet a further object of the invention to provide a fluorescer with improved stability when formulated in cosmetic compositions. Surprisingly it has been found that fluorescer molecules tagged by surface reaction on to naturally occurring asymmetric clay surfaces, act as a fluorescer particle with improved retention properties, low fabric specificity, higher stability in cosmetic formulations and/or yielding improved brightness to substrate (skin/fabric) on use and meets at least one of the above mentioned objects.

    摘要： In particular a porous substrate (FS) like a fabric. Process to clean a substrate, comprising a step of subjecting the substrate to an air-water spray (SPR), generated using a spraying means (N) comprising an air passage (OPA) and a water passage (OPW), wherein air is greater than 90% by volume of the spray, the air velocity is greater than 80 m/s and wherein said air passage does not coaxially surround said water passage. Device to clean soiled fabric (FS) comprising a feed water container (CW) and an air compressor (AC) in fluid communication with a spray nozzle (N) comprising an air passage and a water passage, said device being capable of generating an air pressure in the range of 1 to 3 bar (absolute) and an air velocity greater than 80 m/s at the exit of said nozzle; and the air is greater than 90 % volume of said spray, and wherein said air passage does not coaxially surround said water passage. An external mix spray nozzle is especially preferred in the device.
