Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has an excellent conditioning effect on skin, hair, etc. while satisfying essential conditions as a detergent such as foaming property and detergency, and has a foaming property and usability. And a cleaning composition having good 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 functions as a detergent such as detergency and foaming property, the foam quality during finger washing and rinsing and the ease of use with the fingers are good, and the hair is not brushed. 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 property of the compound of the siloxane compound, it is necessary to mix a large amount, and in this case, there is a disadvantage that fatty acid ethanolamides are adsorbed on the hair and unpleasant peculiar squeaky feeling is caused when rinsing. Had occurred.

Attempts have been made to solve these drawbacks by using fatty acid isopropanolamides, but this has not been fully satisfactory because crystals may precipitate 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.

Less than is preferred. Even if a polyoxyethylene-modified organopolysiloxane having a polyoxyethylene group content of 20% by mass or more is used alone, the desired effect cannot be obtained in many cases due to low persistence upon rinsing. However, a desired effect can be increased by a synergistic effect when used in combination with another water-insoluble siloxane compound.
