DETAILED DESCRIPTION OF THE INVENTION

[0001]

FIELD OF THE INVENTION The present invention relates to a cleaning composition, and more particularly to a cleaning composition having good foaming during cleaning.
The present invention relates to a detergent composition which has good foam removal during rinsing, does not cause sliminess, has little irritation to skin, and has excellent storage stability.

2. Description of the Related Art Cleaning compositions such as kitchen cleaners, hair cleaners, and body cleaners generally contain an anionic surfactant as a main component, and are mainly composed of higher fatty acid salts (soaps) and alkyl sulfates. , Sulfonates and the like are used. However, when soap is used for skin washing, for example, soap scum (higher fatty acid Ca salt) is generated and adheres to the skin at the time of rinsing, so that the lubricity of the skin surface is remarkably reduced, resulting in squeak and tightness. there were. In addition, when alkyl sulfates or sulfonates are used for hair washing, although there is no squeaky or tight feeling, the foam is not easily removed,
There were drawbacks such as poor lubricity of the hair.

[0003] For the purpose of remedying these drawbacks, various attempts have been made to incorporate various auxiliaries such as oils such as higher alcohols and co-activators. Since the effect, the foaming power, the feeling upon use, etc. are reduced, it is easy to be restricted by the prescription, and it has been difficult to obtain a sufficiently satisfactory cleaning agent.

Further, a detergent composition containing an acyl imino dibasic acid type anionic surfactant has been studied (JP-A-2-84496, JP-A-5-117139, JP-A-6-80987). These cleaning agents have a detergency,
Although the foaming power, feeling of use, etc. are improved, the acylimino dibasic acid type anionic surfactant used as a detergent is a derivative from iminodiacetic acid, and it is particularly poor in storage stability at low temperatures. There was a problem.

[0005]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide good foaming, good foam retention, good foam removal at the time of rinsing, no sliminess, low irritation and low-temperature storage stability. Another object of the present invention is to provide an excellent cleaning composition.

[0006]

Under such circumstances, the present inventors have conducted intensive studies and as a result, when a specific glycine derivative and a betaine-type amphoteric surfactant are used in combination,
A cleaning composition having good foaming and foam retention during washing, good foam removal at the time of rinsing, no sliminess, less irritating to the skin, and excellent in low-temperature storage stability is obtained. Thus, the present invention has been completed.

That is, the present invention relates to (A) the general formula (1)
