Embodiment 1-25 and comparative example 1-13

[0064] Using each component shown below, the alkaline aqueous solution composition which has the composition shown in Table 1-3 was prepared. Based on these compositions, the following methods were used to evaluate single solubilization properties and whether or not crystals were re-precipitated in a low-temperature region. The results are shown in Tables 1-3.

Abstract

To provide an alkaline aqueous solution composition which can solubilize a nonionic surface active agent into a high concentration alkaline aqueous solution with a small amount of a solubilizing agent, and furthermore has excellent low temperature stability without depositing a crystal even when stored at a low temperature of -10[deg.]C. The alkaline aqueous solution composition comprises (a) an alkali agent, (b) a nonionic surface active agent, and (c) a solubilizing agent composed of a solubilizing agent (I) of formula (I): R1-X-(CH2)mCOOM1(wherein R1is a 4-22C aliphatic hydrocarbon group or the like; X is >NH, (CH2)nCOOM1or the like; M1is H, an alkali metal or the like; and m and n are each an integer of 1-3), a solubilizing agent (II) of formula (II): R2COOM2(wherein R2is a 3-22C straight-chain aliphatic hydrocarbon group or the like; and M2is H, an alkali metal or the like), and a solubilizing agent (III) of formula (III):SP>3COOM3(wherein R3is a 4-22C branched-chain aliphatic hydrocarbon group or the like; and M3is H, an alkali metal or the like) at a compounding weight ratio of the solubilizing agent(I) to [the solubilizing agent (II)+the solubilizing agent (III)] of 95:5 to 35:65 and at a compounding weight ratio of the solubilizing agent (II) to the solubilizing agent (III) of 70:30 to 30:70.

Description

technical field [0001] This invention relates to aqueous alkaline compositions comprising an alkaline agent and a nonionic surfactant. Background technique [0002] In the past, aqueous alkaline reagents, such as sodium hydroxide, potassium hydroxide, sodium orthosilicate, sodium metasilicate, etc., have been used for various purposes such as neutralization of acids, saponification of oils and fats, and cleaning of oily dirt. In addition, nonionic surfactants have penetrating, emulsifying, and dispersing properties, so they are suitable for use as active ingredients in various detergents, and are suitable for washing hard surfaces such as metals, glass, and fibers. Here, by using an alkaline agent and a nonionic surfactant in combination, a strong alkaline detergent having excellent performance in penetrability, emulsification, dispersibility, and detergency can be obtained. In this case, if these components can be single-solubilized and made into a uniform and transparent ...
