Description

  The present invention relates to a cleaning composition, and more particularly to a cleaning composition having reduced temperature dependence at low temperatures.

For example, a detergent composition used for washing hair, such as a hair washing agent, has an appropriate viscosity so that it can be easily discharged from a container and the composition discharged onto the hair does not easily drip. It is required to be. Further, from the viewpoint of usability, the viscosity is required to be constant regardless of the season, that is, the viscosity should be small with respect to temperature fluctuation.
Conventionally, a polyoxyethylene / polyoxypropylene block copolymer (pluronic block polymer) has been used in the cleaning composition (see, for example, Patent Document 1), and the polyoxyethylene / polyoxypropylene block copolymer is a detergent. And was effective in adjusting the viscosity of cosmetics.

Japanese Patent Publication No. 7-91555

However, the detergent composition blended with this polyoxyethylene / polyoxypropylene block copolymer has the disadvantage that the feeling of use is somewhat inferior, such as foaming worsening compared to the detergent composition not blended with this component. If the polyoxyethylene / polyoxypropylene block copolymer is not blended, the viscosity of the composition is remarkably increased at a low temperature, which causes a problem that it cannot be easily discharged from the container. Therefore, there has been a demand for a detergent composition using a viscosity modifier in place of the polyoxyethylene / polyoxypropylene block copolymer.
Accordingly, an object of the present invention is to provide a detergent composition that has a low temperature dependence on viscosity, and has a small viscosity change even at low temperatures, without using a polyoxyethylene / polyoxypropylene block copolymer. .

  The present invention is a cleaning composition comprising an anionic surfactant, an amphoteric surfactant, and one or more oil agents represented by the following general formula (1). .

（式中、Ｒは水素原子、炭素数が４〜２２のアルキル基、または水酸基を３〜６個有する多価アルコール残基を示し、ｎは４０以上の整数を示す。）

(In the formula, R represents a hydrogen atom, an alkyl group having 4 to 22 carbon atoms, or a polyhydric alcohol residue having 3 to 6 hydroxyl groups, and n represents an integer of 40 or more.)

  In the present invention, it is desirable to further blend a cationized polymer.

Among these, alkyl ether sulfate, N-acylmethyl taurate, and polyoxyethylene alkyl ether sulfate are particularly preferable.

  The compounding amount of the anionic surfactant is preferably 1 to 50% by mass, particularly preferably 5 to 30% by mass, based on the total amount of the detergent composition. When the amount is less than 1% by mass, foaming deteriorates. When the amount exceeds 50% by mass, the shampoo is squeezed.

If it is less than 0.001% by mass, the effect is not exhibited, and if it exceeds 10% by mass, the foaming of the cleaning agent becomes worse.

In the present invention, it is preferable to further blend a cationic polymer.
