Hairdye compositions, in particular, acid hairdye compositions and oxidative hairdye compositions. The first characteristic of these hairdye compositions resides in that they have been thickened so that they remain stable and flowable, give an excellent texture in using and can easily washed away after being used even in a strongly acidic region (i.e., pH 1.5 to 4.0) wherein favorable hair dyeing effects can be achieved. The second characteristic thereof resides in that they have improved dyeing power and improved fasteness to sunlight and laundering, little damage the hair, can improve the hair gloss and have high storage stability. These advantages of the hairdye compositions can be achieved by incorporating therein succinoglycan which is a polysaccharide originating in microorganisms.
染发剂组合物,特别是酸性染发剂组合物和氧化性染发剂组合物。这些染发剂组合物的第一个特点是,它们被增稠,从而保持稳定和流动性,使用时质感极佳,即使在强酸性区域(即 pH 值为 1.5 至 4.0)使用后也很容易洗掉,从而达到良好的染发效果。其第二个特点是,染发剂具有更强的染色力和更快的耐晒和耐洗性,对头发的损伤小,能提高头发的光泽度,并具有较高的储存稳定性。染发剂组合物的这些优点可以通过在其中加入琥珀聚糖来实现,琥珀聚糖是一种源于微
