Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a detergent composition, and more particularly, to a detergent composition that imparts smoothness, creaminess, etc. to foam during washing without impairing detergency, A detergent composition that leaves hair and skin smooth and non-sticky from rinsing to after drying, provides a good feeling of use such as moisturizing, smoothness, and softness, and has an excellent conditioning effect and hair styling effect. .

[Problems to be solved by conventional techniques and inventions] In recent years,
Regarding the performance of hair and skin cleansers, not only improvement in cleansing properties but also conditioning effects such as a good feel on the hair and skin during rinsing and finishing have become very important points.

For this reason, cationic polymers and amphoteric polymers, such as cationized cellulose, generally form a complex with a specific surfactant, and during rinsing, this complex precipitates and deposits on the skin or hair to exert a conditioning effect. Water-soluble polymers, such as, have been used as conditioning agents.

Among these water-soluble polymers, polydimethyldiallylammonium salt type cationic polymer compounds are known to have particularly excellent conditioning effects.

However, since this water-soluble polymer does not dissolve in anionic surfactants or imidacillin surfactants that have high detergency, a detergent with a conditioning effect using these in combination has not been obtained.

Therefore, cleaning agents that are used in combination with surfactants other than these surfactants have been proposed, but this also uses a complex of a polydimethyldiallylammonium salt type cationic polymer compound and the surfactant. There was a problem in that a sufficient conditioning effect could not be obtained due to low precipitation from the composition during rinsing.

In addition, in order to improve this abrasive property, a method has been taken to increase the amount of polydimethyldiallylammonium salt type cationic polymer compound, but this method dries out the complex remaining on the skin and hair. As a result, there are problems such as unpleasant stickiness and stiffness after sufficient drying, and it is not possible to obtain an ideal feel on the skin and hair.

Therefore, the polydimethyldiallyl ammonium salt type cationic polymer compound is uniformly dissolved in the detergent composition and precipitates only during rinsing, resulting in a good foam feel and smooth skin and hair from rinsing to drying. It has been desired to develop a cleaning composition that is non-sticky, smooth, provides a good feeling of use such as moisturizing, smoothness, and softness, and provides excellent conditioning effects.

[Means to solve the problem]

Under these circumstances, the present inventors conducted intensive research and surprisingly found that if a specific betaine surfactant and a specific surfactant are used in combination, the conventional anionic and imidacillin surfactants It has become possible to dissolve the polydimethyldiallylammonium salt type cationic polymer compound, which was thought to be insoluble in the activator, and the complex precipitates well during rinsing, resulting in a good foam feel. After rinsing and drying, the skin and hair are not sticky, smooth, moisturized, and smooth.
It has been discovered that a cleaning composition with excellent conditioning effects that provides a good feeling of use such as softness can be obtained,
The invention has been completed.
