  • Method of detecting protein and a kit using the same
    Patent number: 6703243
    Abstract: A method for detecting protein present on the surface of a sample is disclosed, wherein substances present on a portion of said surface are transferred to a sampling means and wherein, subsequently, these substances are contacted with a reagent capable of forming or changing color upon reaction with protein. Finally, the color changed or formed by this reaction is visually determined. In this method, the substances transferred onto the sampling means are also contacted with a specific type of nonionic or zwitterionic surfactant.

  • Process for preparing a solid detergent block
    Patent number: 5719111
    Abstract: A detergent block of compressed granular material is provided, said block having a weight of 0.2-10 kg, being substantially free of phoshate builder material, and comprising a granulated builder material, an alkaline agent and a compressing aid. A process is also provided for preparing a block of compressed granular material being substantially free of a phosphate builder and having a weight of 0.2 to 10 kg, said process involving the steps of(i) granulating a non-phosphate builder material, with 0.1-10% by weight based on the weight of the builder of a co-ingredient selected from polycarboxylic polymer solutions, alkali metal silicate solutions, and mixtures thereof;and(ii) compressing a particulate mixture of said granulated builder material and other components of the block, including a compressing aid, in a mould under a pressure of 3-30 kN/cm.sup.2.
