A water-based composition containing: (A) fine cellulose fibers having a number-average fiber diameter of 0.5 nm or more and 200 nm or less, and having a carboxy group content of 0.1 mmol/g or more, wherein the carboxy group forms a salt with an alkali metal; and (B) an additive containing one or more compounds having carbon atoms and nitrogen atom or atoms, wherein a ratio thereof per molecule of the compound (number of carbon atoms/number of nitrogen atoms) is 3 or more and 45 or less, wherein the content of the component (A) is 0.2% by mass or more and 10% by mass or less, and wherein the content of the component (B) is 3 parts by mass or more and 150 parts by mass or less, based on 100 parts by mass of the component (A), and wherein the water-based composition has a viscosity at 80°C at a rotational speed of 30 rpm of 80 mPa•s or more. Since the fine cellulose fibers or a salt composite thereof of the present invention retains a high viscosity even under high temperatures, the fine cellulose fibers or a salt composite thereof can be suitably used in various industrial applications represented by thickening agents during gas and oil drilling, cosmetic applications, and other applications requiring manufactured article stability at high temperatures.
一种水基组合物,含有:(A) 纤维平均直径大于或等于 0.5 纳米、小于或等于 200 纳米、羧基含量大于或等于 0.1 mmol/g 或更多,其中羧基与碱金属形成盐;和 (B) 添加剂,含有一种或多种具有碳原子和氮原子的化合物,其中每分子化合物的比例(碳原子数/氮原子数)为 3 或更多和 45 或更少,其中组分 (A) 的含量为 0.其中组分(B)的含量为 3 份(质量)或更多和 150 份(质量)或更少(以 100 份(质量)的组分(A)为基数),并且其中水基组合物在 80°C 时以 30 rpm 的转速旋转时的粘度为 80 mPa-s 或更高。由于本发明的细纤维素纤维或其盐类复合材料即使在高温下也能保持较高的粘度,因此细纤维素纤维或其盐类复合材料可适用于以天然气和石油钻井过程中的增稠剂为代表的各种工业应用、化妆品应用以及其他需要制成品在高温下保持稳定的应用。
