DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention has an excellent conditioning effect on hair and the like while satisfying essential conditions as a detergent such as foaming property and detergency, and has good foam quality and usability. And a cleaning composition having excellent low-temperature stability.

[0002]

2. Description of the Related Art In recent years, demands for hair care products have been diversified with an increase in consumers' awareness of hair care.
In detergents such as shampoos, in addition to the basic function as a detergent such as detergency and foaming property, the foam quality during finger washing and rinsing is good, and it has good usability, as it does not irritate the hair. It is also an important factor to satisfy the good finish feeling such as good hair stiffness, flexibility and good combability after drying.

Hitherto, cationic polymers such as cationized cellulose and siloxane compounds have been widely used as conditioning agents for shampoos. However, when a shampoo containing only a cationic polymer is used continuously, the cationic polymer accumulates on the hair, resulting in stickiness and stiffness. A shampoo containing a siloxane compound is excellent in finish feeling, but has satisfactory foaming properties due to its inherent defoaming property, which significantly reduces foaming and deteriorates finger passing during hair washing. Was not. On the other hand, for the purpose of improving foaming, many attempts have been made to blend fatty acid ethanolamides such as lauric acid monoethanolamide and lauric acid diethanolamide.
In order to cover the defoaming properties due to the formulation of the siloxane compound, it is necessary to formulate a large amount, in which case the fatty acid ethanolamides are adsorbed on the hair, causing a unique unpleasant squeaky feeling when rinsing. Had occurred.

Attempts have been made to eliminate these drawbacks, for example, by using isopropanolamide of a straight-chain fatty acid. However, such methods have not been fully satisfactory because crystals may be precipitated at low temperatures.

[0005]

SUMMARY OF THE INVENTION With the background of the prior art as described above, an object of the present invention is to provide foaming properties and finger rubbing during washing and rinsing while satisfying essential conditions as a detergent such as foaming properties and detergency. Detergent with excellent usability such as good passability and not squeezed hair, good finish of hair after drying, suppleness and good combability, and excellent low temperature stability. Providing a composition.

[0006]

Means for Solving the Problems The present inventors have made intensive studies to achieve the object of the present invention, and as a result, have found that a branched-chain fatty acid alkanolamide having a specific branched-chain acyl group and a siloxane compound can be used as a detergent. It has been found that the above-mentioned drawbacks are improved when incorporated into the composition. Further, they have found that the effect is enhanced by further using a cationized polymer in combination, and completed the present invention. That is, the invention of claim 1 of the present invention is a detergent composition comprising a branched-chain fatty acid alkanolamide having a branched-chain acyl group having an average carbon number of 8 to 22 and a siloxane compound. A second aspect of the present invention is the cleaning composition according to the first aspect, wherein the branched-chain fatty acid alkanolamide is a branched-chain fatty acid monoisopropanolamide. Further, claim 3 of the present invention is the detergent composition according to claim 1, wherein the branched-chain fatty acid alkanolamide is isostearic acid alkanolamide. A fourth aspect of the present invention is the cleaning composition according to the first aspect, wherein the branched-chain fatty acid alkanolamide is isostearic acid monoisopropanolamide.
