Water-dispersible polysaccharide derivatives of reduced glyoxal content, and a process for decreasing the glyoxal content in glyoxal-crosslinked polysaccharide derivatives
摘要：
A description is given of glyoxal-treated polysaccharide derivatives which, to decrease the unbound glyoxal, are treated with an aqueous solution of one or more water-soluble aluminium salts, or one or more water-soluble borates, or a combination of one or more water-soluble aluminium salts and one or more water-soluble borates, and, if appropriate, with suitable buffer substances to set the pH, and then dried.A description is likewise given of a process for decreasing the content of unbound glyoxal in glyoxal-treated polysaccharide derivatives.
摘要（中）：

对乙二醛处理的多糖衍生物进行了描述，为了减少未结合的乙二醛，用一种或多种水溶性铝盐或一种或多种水溶性硼酸盐的水溶液或一种或多种 水溶性铝盐和一种或多种水溶性硼酸盐，并且如果合适，用合适的缓冲物质来调节pH值，然后干燥。 同样给出了降低乙二醛处理的多糖衍生物中未结合乙二醛的含量的方法。
