  公开（公告）日：2012-04-26

  This invention relates to bis-azo colorants for use as bluing agents, laundry care compositions comprising bis-azo colorants that may serve as bluing agents, processes for making such bluing agents and laundry care compositions and methods of using the same. The bluing agents are generally comprised of at least two components: at least one chromophore component and at least one polymeric component. These bluing agents are advantageous in providing a whitening effect to fabrics, while not building up over time and causing undesirable blue discoloration to the treated fabrics.

  这项发明涉及用作蓝色剂的双偶氮染料，包括可能用作蓝色剂的双偶氮染料的洗衣护理组合物，制备此类蓝色剂和洗衣护理组合物的方法以及使用它们的方法。蓝色剂通常由至少两个组分组成：至少一个色团组分和至少一个聚合物组分。这些蓝色剂具有优点，可以为织物提供漂白效果，同时不会随着时间累积并导致对处理过的织物产生不良的蓝色变色。

• Enzymatic high range glucose test

  A test composition comprising glucose oxidase, a peroxidatively active component, a chromogenic indicator system capable of providing a detectable response and a borate buffer capable of providing an initial pH above about pH 7 is particularly useful for the semiquantitative determination of high range glucose, (i.e. glucose concentrations of 1,000 mg/dL to 10,000 mg/dL). A preferred indicator system is a water soluble iodide salt and poly-(vinylpyrrolidone). The use of a borate buffer capable of providing an initial pH above about pH 7 permits greatly improved resolution for the semiquantitative determination of high range glucose when the test composition is incorporated onto a carrier matrix to prepare a solid state unitary test device.

  由葡萄糖氧化酶、过氧化活性成分、能提供可检测反应的显色指示剂系统和能提供高于约 pH7 初始 pH 值的硼酸盐缓冲液组成的测试组合物特别适用于高范围葡萄糖的半定量测定（即葡萄糖浓度为 1,000 mg/dL 至 10,000 mg/dL）。首选的指示剂系统是水溶性碘盐和聚（乙烯基吡咯烷酮）。使用硼酸盐缓冲液可使初始 pH 值高于约 pH 值 7，当测试组合物加入载体基质以制备固态单元测试装置时，可大大提高高范围葡萄糖半定量测定的分辨率。
