    摘要: The invention relates to cleaning compositions comprising (a1) a phenolic antioxidant of the formula (1) and/or (2); and/or (a2) an antioxidant of the formula (3); and (b) a surfactant comprising a long alkyl or alkenyl chain. The antioxidants used according to the invention have excellent reactivity, good stability to hydrolysis, particularly in an alkaline medium, and, because of their solubility, can be easily incorporated into the soap formulations.

    摘要: A method of and apparatus for supplying pulverulent material includes a fluidizing unit which is introduced into a transport container containing the pulverulent material. The fluidizing unit causes suspension or floating of the pulveulent material in the transport container. A suction unit and a discharge unit such as an injector withdraws fluidized pulverulent material and conveys it to the processing device. The fluidizing unit and the discharge unit are preferably combined to a constructional unit which is adjustable relative to the fluidizing unit. Thus, the use of separate powder containers is avoided as the transport container in which the pulverulent material is contained is directly used as a powder container.
