Abstract
An aqueous solution composition of a strong alkali and a nonionic surface active agent comprising: (a) a strong alkali, (b) a nonionic surface active agent having an HLB value of 3-18, and, as a solubilizing agent, (c) a specific type of carboxylic acid is disclosed. The composition contains a strong alkali and a nonionic surface active agent having an HLB value usually of 3-18 at high concentrations and stably and is homogeneous and transparent. Thus, it is useful for a variety of applications requiring both alkalinity and detergency, for example, as wettability promoting agents of glass, fiber, metal, and earthenware surfaces as well as various toiletry products.
