Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a foaming agent having a sufficient cleaning effect and a good conditioning effect, and when filled in a foamer container, the foam discharged from the nozzle has a good feeling, The present invention relates to a shampoo composition which does not easily cause clogging of a film, and is particularly suitable for filling a former container.

[0002]

2. Description of the Related Art Conventionally, shampoos are mainly composed of various anionic surfactants in consideration of foaming property, detergency, conditioning effect, etc., and by selecting a conditioning agent or by combining them.
Considerations have been made to meet the required quality.

On the other hand, in recent years, non-gas formers, which are containers that can generate creamy foam using air pressure, have been developed for various uses as containers that are environmentally friendly, easy to use, and excellent in usability. Yes ("Food and containers" Vo
1.34, no. 8, 1993 and Vo 1.36, N
o. 3, 1955). By the way, as a foaming detergent composition capable of discharging fine foam from such a foamer container, a composition containing a surfactant, a monohydric alcohol and a polyhydric alcohol has been proposed (JP-A-5-132700).
No.). In addition, it is possible to discharge bubbles with a good feel,
Further, a detergent composition containing a surfactant and a polyhydric alcohol which does not easily cause clogging even when used for a long time has been proposed (Japanese Patent Application Laid-Open No. Hei 10-218744).

[0004] However, the shampoo compositions used in these conventional foamer containers have a low conditioning effect. If various oils and the like are blended in order to overcome this, it is difficult to obtain creamy and stable foam.
In addition, the pump may be clogged by long-term use.

[0005]

SUMMARY OF THE INVENTION The present invention provides a cleaning effect,
Excellent in conditioning effect, when filled in a foamer container, the foam discharged from the nozzle shows a good feel and hardly causes clogging of the porous membrane in the foamer container. It is an object to provide a suitable shampoo composition.

[0006]

Means for Solving the Problems Under such circumstances, the present inventors combined an anionic surfactant, a cationized polymer, a specific nonionic surfactant or an oil component, and further specified a monohydric alcohol and a polyhydric alcohol. By blending in proportions, good foam feeling, foam stability, sufficient washing effect and good conditioning effect (good hair cohesion, smoothness, crispness, and lack of dryness) can be obtained, and a foamer container It has been found that clogging does not occur during use even when it is filled in, and the present invention has been completed based on these findings.

That is, the present invention relates to the following components (A) to (E): (A) anionic surfactant (B) cationic polymer (C) a nonionic surfactant having an HLB value of 10 or less; One or more substances selected from ionic surfactants and oils; (D) a monohydric lower alcohol, (E) a polyhydric alcohol, and a mixture of the (D) component and the (E) component. A shampoo composition characterized in that the weight ratio (D) / (E) is 1/6 to 5/1 and the total amount is 1% by weight or more. Further, according to the present invention, there is provided the shampoo composition, wherein the (A) anionic surfactant is an amino acid-based surfactant.

Further, in the present invention, the weight ratio (D) / (E) of the compounding amount of the component (D) and the component (E) is 1/6 to less.
5/1. If the weight ratio (D) / (E) is less than 1/6, sufficient foam quality cannot be obtained, while if it is more than 5/1, clogging of the former container tends to occur.

The shampoo composition of the present invention is generally used in this type of shampoo in addition to the above essential components, if necessary depending on the purpose of use, as long as the object of the present invention is not impaired. Various additive components can be blended. For example, cationic surfactants, amphoteric surfactants,
