Description

  The present invention relates to a composition comprising a surfactant.

  Surfactants are used in a wide range of fields for the purposes of foaming, washing, penetration, dispersion, emulsification and the like. Products containing surfactants include, for example, fragrances, household / commercial / industrial detergents, detergents for emulsion polymerization and suspension polymerization, pharmaceutical and agrochemical formulations, and exfoliation in semiconductor manufacturing. And cleaning agents.

  In recent years, increasing the concentration of surfactants for the purpose of manufacturing the surfactants themselves, the productivity of products containing the surfactants, storage and transportation, reducing adverse effects on the environment, ease of use, and reducing costs. Is being considered. Such high concentration is typically achieved by reducing the amount of water contained therein.

  However, a composition simply having an increased surfactant concentration has a high viscosity, which makes it difficult to produce itself due to difficulty in stirring in the production process or reduction in line transfer efficiency. In addition, there is a problem that the handling accuracy at the time of use is inferior, for example, the measurement accuracy is lowered. In addition, depending on the type of surfactant and other conditions, it may be difficult to increase the concentration itself, or even if a composition containing a high concentration of the surfactant can be produced, the shape change over time occurs. In some cases, the storage stability may deteriorate. Furthermore, a composition containing a surfactant at a high concentration is often used after being dissolved in water, but there is a problem that it takes time to dissolve in water, and in particular, there is a problem that the solubility in cold water is inferior. .

  By the way, Patent Document 1 describes a concentrated liquid cleaning composition for kitchen containing a specific amount of a specific surfactant, and at least one of ethanol, propylene glycol and polyethylene glycol is used as a viscosity reducing agent. Is included. Patent Document 2 describes a liquid detergent composition containing 15% by mass or more of a nonionic surfactant and 0.01 to 10% by mass of glycerin or a derivative thereof.

  Therefore, the present invention is low in viscosity over a wide temperature range, excellent in ease of manufacture and handling itself, can be made higher in concentration of the surfactant, has excellent shape stability over a wide temperature range, and has storage stability. It aims at providing the composition which is high and is excellent in the solubility to cold water.

  As a result of intensive studies to solve the above-mentioned problems, the inventors of the present invention have a low viscosity over a wide temperature range by blending 3-methoxy-3-methyl-1-butanol with a high concentration surfactant. A composition that is excellent in its own ease of manufacture and handling, can have a higher concentration of surfactant, has excellent shape stability over a wide temperature range, has high storage stability, and has excellent solubility in cold water.

・ Viscosity (2)
Hereinafter, as an evaluation assuming a high-concentration surfactant aqueous solution, an aqueous solution having the composition (formulation 2) shown in Table 3 was prepared, and the viscosity thereof was measured. The results are shown in Table 4.

  The composition of Example 2 containing MMB as a solvent has a lower viscosity over a wide temperature range than the compositions of Comparative Examples 4 to 6 containing other solvents, and can achieve low viscosity particularly at low temperatures. I understand.

[Example 3 and Comparative Examples 7 to 9]
-Surfactant concentration In order to evaluate the upper limit of the surfactant concentration in the composition, 1 g of fluorosurfactant (N- (2,3-dihydroxypropyl) -N-propylperfluorooctanesulfonamide) and After mixing with 10 g of solvent and confirming that a part of the fluorosurfactant is precipitated, 1 g of the same solvent is added under stirring, and the composition is uniformly and transparently dissolved.
