Description

  The present invention relates to a detergent composition such as food, tableware, and clothing having excellent foaming properties and cleanability.

  Conventionally, in detergents for clothing, kitchen detergents, hair detergents, and body detergents, a detergent composition has been established according to the type of object to be cleaned and the type of dirt. For example, anionic surfactants having excellent basic surface activity such as foaming power, emulsifying power, solubilizing power, and dispersing power have been mainly used. In addition, in consideration of the environment, an attempt to shift the main component from an anionic activator to a nonionic activator has been actively made, and polyoxyethylene alkyl ether, polyoxyethylene polyhydric alcohol fatty acid ester, polyoxyethylene An ethylene oxide nonionic surfactant such as ethylene alkylphenyl ether is used. In addition, alkaline detergents, chelate builders, fluorescent agents, bleaching agents, enzymes, etc. in clothing detergents, and fatty acid alkanolamides and alcohol ethoxylate-based nonionic surfactants in kitchen detergents and hair detergents are in terms of foaming power and detergency. Have been used together.

   However, these surfactants and the above combinations are only equivalent to or less than the cumulative results in the performance of each component, and do not expect the effect of increasing the ability of the surfactant as the main component. It was.

  As the detergent composition, a sugar-based nonionic surfactant and a detergent composition having a low irritation, creamy and good foaming using sugar residues and cationic groups have been reported (for example, Patent Document 1). reference.). In addition, a detergent composition having foamability and detergency using a specific phosphate ester surfactant, a sugar alcohol and a specific glycerin derivative has been reported (for example, see Patent Document 2). Stability of the product, sufficient foaming properties and cleaning properties were not obtained.

  The present invention uses a polyglycerin alkyl ether as a component in a detergent that requires basic surface activity such as foaming power, detergency, emulsification power, solubilization power, and dispersion power. For the purpose of enhancing the performance, a builder is blended, specifically to improve foaming power and cleaning power.

  In view of the above points, the present inventors have intensively studied to arrive at the present invention. That is, the present invention has been found to be suitable for washing food, tableware, and the like by containing polyglycerin alkyl ether, and has led to the present invention.

  According to the present invention, it is possible to produce a detergent composition having a surface activity such as foaming power, cleaning power, emulsifying power, solubilizing power, and dispersing power, which is impossible with conventional cleaning agents.

  Hereinafter, the present invention will be described in detail.

  The polyglycerol polymerization degree of the polyglycerol alkyl ether of the present invention is preferably 2 to 20 and more preferably 2 to 10 from the viewpoints of manufacturability and usability. Moreover, it is desirable from a viewpoint of foaming power, detergency, emulsification power, and solubilization to have an alkyl group having 6 to 22 carbon atoms, more preferably 10 to 14 carbon atoms. The alkyl chain length is not limited to a straight-chain type or a branched type, but it is desirable to select it freely from the properties of the detergent composition to be constituted. Furthermore, it is desirable from the viewpoint of foaming power, detergency, emulsifying power, and solubilization that the polyglycerol alkyl ether is a polyglycerol monoalkyl ether.

  As a method for producing polyglycerin alkyl ether, a method in which glycidol is added to and reacted with an aliphatic alcohol so that the molar ratio of the alcohol / glycidol is specified in the presence of a basic catalyst, and α-olefin is reacted with polyglycerin. A method obtained by reacting an epoxide, a method of ring-opening an alkyl glycidyl ether using polyglycerin in the presence of an acid catalyst or an alkali catalyst, and the like can be mentioned, but it is not particularly limited. Also, it can be adsorbed with activated carbon or activated clay, deodorized under reduced pressure using water vapor or nitrogen as a carrier gas, washed with acid or alkali, or subjected to molecular distillation.

If it is less than 0.01 part by weight, sufficient foaming and feel improvement effects cannot be obtained, and if it exceeds 50 parts by weight, preparation is difficult due to problems such as viscosity of the composition, and the feeling of use is inferior.

  In the cleaning composition of the present invention, nonionic surfactants other than anionic surfactants, amphoteric surfactants and polyglycerin alkyl ales can be blended, and performance such as foaming can be further improved. Therefore, it is preferable.

A 20-fold diluted aqueous solution was prepared for each cleaning composition, and 100 ml of this solution (liquid temperature 30 ° C.) was injected into a 500 ml graduated cylinder. Next, a stirring blade was placed in the solution, and stirring was performed for 1 minute at a rotation speed of 1000 rpm. Then, the volume (ml) of the generated foam was measured and used as the amount of foaming.

<Foamability>
◎: Foaming 300 ml or more ○: Foaming 250 ml or more and less than 300 ml Δ: Foaming 200 ml or more and less than 250 ml X: Foaming less than 200 ml Note that ◎ and ○ are acceptable products.

Test example 2
A cleaning composition was prepared based on the formulation shown in Table 3 as a cleaning fineness, and a detergency test was performed.

A flat 20 cm ² glass plate with artificial fouling attached to 700 ml of a 0.2% aqueous solution of each cleaning composition (liquid temperature 30 ° C.) was set on a dedicated stand and submerged, and the stirring blades were rotated at 250 rpm. Rotated for minutes. After completion of the rotation, the glass plate was taken out and weighed after drying, and the washing rate was calculated using the following calculation formula.

  Cleaning rate = {(weight before cleaning−weight after cleaning) / weight before cleaning} × 100%

<Detergency>
◎: Detergency 95% or more ○: Detergency 85% or more and less than 95% △: Detergency 50% or more and less than 85% ×: Detergency 50% or less Note that ◎ and ○ are acceptable products.

Test example 3
A cleaning composition was prepared based on the formulation in Table 5, and a storage stability test with time was conducted.
The prepared cleaning composition was stored at 5 ° C., 25 ° C., and 40 ° C., and the stability was confirmed visually.

<Detergency>
