Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to cleaning compositions. Specifically, the present invention relates to a detergent composition that generates thick foam, has viscoelasticity, spreads well, and gives a fine slimy feel, and is particularly suitable for use as a hair shampoo.

A wide variety of products containing various ingredients have been known as detergent compositions for hair, body, etc., but they are lacking in terms of foamability, sliminess, viscoelasticity, spreadability, and finish when used. I can't say it's enough.

Under the above-mentioned circumstances, the present inventors conducted various studies with the aim of improving the feel of hair shampoo, imparting viscoelasticity, sliminess, or spreadability to detergents, and conditioning. However, it has been discovered that this objective can be easily achieved by a combination of specific substances.The present invention is based on this knowledge.

The present invention will be explained in detail below. The cleansing composition of the present invention is used for hair, body, etc., especially hair, and includes conventionally known general-purpose fragrances, hydrotropes, bactericidal agents, tonic agents, superfat agents, ultraviolet absorbers, dandruff removers, and chelating agents. ,
Emulsifiers, dyes, etc. may be included as appropriate, and one or two selected from a) amphoteric surfactants, b) cationic surfactants, cationic celluloses, cationic polymers, and amphoteric resins. It contains at least one conditioner and C) a polymeric thickener as essential ingredients.

The amphoteric surfactants are conventionally known, such as alkyldimethylamine acetate betaine, alkylpropyl betaine, 2-alkyl-N-carboxymethyl-
N-hydroxyethylimidazolinium betaine, β-
Examples include alkyl(lauryl)aminopropionate, β-alkyliminodipropionate, and the like.

Conventionally known cationic surfactants can be used, but quaternary ammonium salts and quaternary pyridinium salts are particularly preferred, such as alkyltrimethylammonium salts, alkylpyridinium salts, alkylisoquinolium salts, and dialkyltrimethylammonium salts. Morpholinium salts and the like are used.

Examples of cationized celluloses include quaternary nitrogen-substituted cellulose derivatives, such as commercially available Polymer JR
(manufactured by UCC) or Leogard G (manufactured by Lion). Examples of cationic polymers include quaternary nitrogen-containing poly(trialkylaminoethyl methacrylate) derivatives, homopolymers of dimethyldialylammonium chloride, copolymers of dimethyldiallylammonium chloride and acryloamide, or tetraethylenepentamine and epichlorohydrin. . In addition, as amphoteric resins, there are compounds represented by the following formula,
Specific examples include those shown in Table 1, and a commercially available product is Yukaformer AM75W (manufactured by Mitsubishi Yuka).

11th! Examples of the surface polymer thickener include hydroxyethylcellulieethylene oxide, polyacrylamide, and the like, with cellulose derivatives being preferably used. Among cellulose derivatives, hydroxyethylcellulose and hydroxypropylmethylcellulose are preferred, and hydroxyethylcellulose is more preferred.

The blending ratio of these essential components is: a) 3.0 to 35.0% by weight of the amphoteric surfactant, preferably 5.0 to 3% by weight;
00% by weight, b) 0.03-10% of conditioner.
0% by weight, preferably 0.05-50% by weight, C) o. i~8.0% by weight, preferably 0.1~
50% by weight is chosen.

The pH of the cleaning composition of the present invention is preferably adjusted to be equal to or lower than the isoelectric point of the amphoteric surfactant contained therein.

The isoelectric point refers to a state in which when an ampholyte dissociates into a base and an acid in a solution, the degree of ionization of the two becomes equal. That is, it is a state in which the cationic and anionic properties of the amphoteric surfactant are balanced, and it is indicated by the pH value (hydrogen ion concentration) in that case. Through this adjustment, the composition of the present invention exhibits the effects of both a shampoo agent and a rinse agent, and achieves a finish retention effect.

The composition of the present invention further contains 10.0% by weight or less, preferably 8.0% by weight or less of a lower alcohol such as ethyl alcohol or isopropyl alcohol, thereby improving the compatibility of the system of the present composition. It can be improved.

The cleaning composition of the present invention exhibits a rich foaming property due to the combination of each component as described above, and provides a foam that is viscoelastic, spreadable, and has a fine slimy feel with good slippage. In addition, if the pH of this composition is below the isoelectric point of the amphoteric surfactant, when used as a hair shampoo, the finish of the hair will be good (no rinse or treatment agent is required. There is no tangle, and after drying, the finish is moist and supple, and it is extremely difficult to get curls, and even if it does, it is minor and can be easily fixed.

Next, the present invention will be explained in more detail with reference to Examples.
The present invention is not limited to the following examples unless it goes beyond the gist thereof. In the examples, "%" and "parts" all refer to "% by weight" and "parts by weight."

Example 1 Citric acid・・・・・・・・・・・・・・・・・・・・・

・Appropriate amount■ First, mix and dissolve ■ for the specified amount of the above ingredients. An appropriate amount of purified water is used in this dissolution step. Next, add (1) and (2) sequentially to make it uniform. After making up to 100 parts using purified water, ■
was added to adjust the pH to 45, below the isoelectric point of cocoamidopropyl betaine. When the obtained hair shampoo was used by women with self-reported damaged hair, it was found that when washing hair, the foam had a slimy feel and slipped easily, did not tangle the hair, and did not require rinsing or hair treatment after rinsing. I felt like I had been conditioned to the extent that I didn't.

Even after drying, the finish remained smooth and smooth. I was able to easily fix my sleep the next morning by giving it plenty of water.

Procedural amendment (voluntary) 3. Relationship with the case of the person making the amendment Patent applicant address 699-15, Kitayo, Kokufu-Hongo, Oiso-machi, Naka-gun, Kanagawa Prefecture, Claims of the specification to be amended and claims of the invention Detailed explanation column Sheet 1 (1) Specification, page 6, line 4, after "Selected." [The remainder is balanced with water. ” is added.

(2) Same, page 6, line 19, add the following sentence after "It is possible."

"Furthermore, if the composition of the present invention contains an anionic surfactant that is stable in an acidic region, for example, an anionic surfactant such as an ammonium salt, this anionic surfactant will exist stably even in an acidic region, so it will foam.
