Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a novel liquid cleaning composition, more specifically,
The present invention relates to a liquid cleansing composition for body cleansing that has excellent foaming properties and creamy foam quality.

BACKGROUND OF THE INVENTION Conventionally, higher fatty acid soaps, synthetic anionic surfactants such as sodium σ-olefin sulfonate, and alkyl ether sulfate are known as cleaning active ingredients used in liquid detergents for body washing. However, these cleaning active ingredients are not always fully satisfactory; for example, higher fatty acid soaps have good rinsing properties and a refreshing feeling after use, but have the disadvantage of poor foaming properties, and - Although synthetic anionic surfactants such as sodium olefin sulfonate and alkyl ether sulfate have good foaming properties, they have the disadvantage of poor creaminess of the foam.

Therefore, in liquid detergents for body washing, the above-mentioned higher fatty acid soaps and synthetic anionic surfactants are rarely used alone, and usually higher fatty acid soaps are combined with synthetic anionic surfactants and nonionic surfactants. It is used in combination with other agents. However, in such a combination, both have excellent foaming properties and creamy foam properties during use, and have good foam smoothness.
At present, no liquid detergent for body washing has been obtained that fully satisfies the characteristics required.

On the other hand, attempts have been made to add cationic polymers for the purpose of producing rich foaming (Japanese Patent Laid-Open No. 61-73
Publication No. 99). However, even in this case, it is difficult to sufficiently enhance the creaminess of the foam.

Problems to be Solved by the Invention The present invention overcomes the drawbacks of conventional liquid detergents for body washing, and provides a liquid detergent for body washing that has good foaming properties and foam creaminess during use. It was made for the purpose of providing a composition.

Means for Solving the Problems As a result of intensive research to develop a liquid detergent composition for body washing having the above-mentioned favorable properties, the present inventors have developed a higher fatty acid soap, a cationic polymer, and a glucose derivative. It was discovered that the object could be achieved by a composition containing each of them in a predetermined ratio, and based on this knowledge, the present invention was completed.

That is, the present invention provides (A) higher fatty acid soap 5 to 3
(B) 105 to 1.0% by weight of a cationic polymer, and (C) a glucose derivative.

The present invention will be explained in detail below.

In the composition of the present invention, there are no particular restrictions on the higher fatty acid soap used as component (A), including those conventionally used in liquid detergents for body washing, such as animal fats and oils represented by beef tallow and mutton tallow; Vegetable oils such as coconut oil, palm oil, palm kernel oil, soybean oil, olive oil, safflower oil, cottonseed oil, etc., or capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, oleic acid, behenic acid, etc. Select and use any fatty acid selected from at least one type of higher fatty acids and those saponified or neutralized with an alkali such as sodium hydroxide, potassium hydroxide, and triethanolamine. I can do it.

The content of the higher fatty acid soap is 5 to 3% based on the weight of the composition, from the viewpoint of stability and usability of the composition.
It is selected in the range of 0% by weight. If this content deviates from the above range, the object of the present invention cannot be fully achieved.

In the composition of the present invention, the cationic polymer used as component (B) is a water-soluble cationic polymer compound having quaternary nitrogen. nl:L is an integer from 100 to 5000)

A copolymer-type cationic polymer compound of dimethyldiallylammonium chloride and acrylamide represented by It is an ethyl group, m is 50 to 2000
At least one selected from the hydroxyethyl cellulose cationized products represented by the formula (an integer of 0) is preferably used.

Examples of the polydimethyldiallylammonium chloride cationic polymer compound represented by the general formula (I) include Marquat 100 (manufactured by Merck & Co., Ltd., trade name), and dimethyldiallylammonium chloride represented by the general formula (n). As a copolymer-type cationic polymer compound of acrylamide and acrylamide, for example, Marquat 550
Examples of the cationized hydroxyethylcellulose represented by the general formula (I [ Co., Ltd., product name] etc. are commercially available.

One type of these cationic polymers may be used, or two types may be used.
A combination of two or more species may be used, and the content thereof is selected in the range of 0.05 to 1.0% by weight, preferably 0.1 to 0.7% by weight, based on the weight of the composition. If this amount is less than 0.05% by weight, good foaming properties and creaminess of the foam cannot be obtained, and if it exceeds 1.0% by weight, the viscosity becomes too high and there is a tendency that good liquid properties cannot be obtained.

In the composition of the present invention, the glucose derivative used as component (C) has the general formula % formula % (wherein R4 and R5 are each a saturated or unsaturated alkyl group having 8 to 20 carbon atoms, They may be the same or different from each other, and the sum of x and y is an integer in the range of 50 to 200. substances are preferably used.

The glucose derivative can be easily produced by esterifying methyl glucoside and then adding ethylene oxide thereto. One type of glucose derivative may be used, or two or more types may be used in combination, and the content thereof is preferably 0.3 to 10% by weight, more preferably 0.3% to 10% by weight, based on the weight of the composition. 5
-6.0% by weight. If this amount is less than 0.3% by weight, good foaming properties and creaminess of the foam cannot be obtained, and if it exceeds 10% by weight, the viscosity becomes too high and there is a tendency that good liquid properties cannot be obtained.

There are no particular restrictions on the method for preparing the liquid skin cleansing composition of the present invention, and it can be prepared in liquid or cream form according to commonly used methods. At this time, various components may be added as necessary within a range that does not impair the purpose of the present invention.
