Disclosed is an aqueous composition prepared by dispersing water in a base fluid in the presence of surfactants, which composition comprises, as the surfactants,
(A) at least one of the compounds represented by the general formula:
R¹-O-(R²-O)n-H
wherein R¹ is an alkyl group having 3 to 10 carbon atoms, R² is an alkylene group having 2 or 3 carbon atoms, and n is an intefer of 1 to 20; however, when n is an integer of 2 or more, the repeating unit (R²-O) may contain both of alkylene groups having 2 carbon atoms and alkylene groups having 3 carbon atoms mixedly, and
(B) at least one ionic surfactant.
The aqueous composition of the present invention is transparent in appearance, and has a low viscosity, and can employ a fluid having a high viscosity to obtain a composition of desired viscosity. Said composition is also excellent in mechanical and chemical stabilities. In said composition, phase inversion by temperature is reversible.
本发明公开了一种水性组合物,其制备方法是在有表面活性剂存在的情况下,将水分散在基液中,作为表面活性剂,该组合物包括
(A) 至少一种由通式表示的化合物:
R¹-O-(R²-O)n-H
其中,R¹ 是具有 3 至 10 个碳原子的烷基,R² 是具有 2 或 3 个碳原子的亚烷基,n 是 1 至 20 的整数;但是,当 n 是 2 或 2 以上的整数时,重复单元(R²-O)可同时包含具有 2 个碳原子的亚烷基和具有 3 个碳原子的亚烷基,以及
(B) 至少一种离子表面活性剂。
本发明的水性组合物外观透明,粘度低,可使用高粘度流体来获得所需粘度的组合物。所述组合物还具有出色的机械和化学稳定性。在所述组合物中,由温度引起的相反转是可逆的。
