Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleansing agent, and more particularly to a cleansing agent which has a conditioning effect on hair and causes little damage to the hair even after repeated washing.

[0002]

2. Description of the Related Art Conventionally, a shampoo containing an alkyl sulfate salt, an alkyl polyoxyethylene sulfate salt or the like as a main cleaning agent is usually used for washing hair. After washing the hair and washing with water, another rinse agent can be applied and rewashed with water. There were many. This rinsing may be omitted, but in that case, the dryness of the hair after washing was likely to occur due to excessive degreasing. Recently, the number of people who wash their hair every day has increased, and the morning shampoo has become more frequent. In that case, it is difficult to perform the two steps of shampoo and rinse due to the time required for washing hair, and the adverse effects such as dryness due to excessive degreasing are likely to occur. Therefore, it is also proposed to replace a part or all of the sulfate-based anionic surfactant, which is the main agent of shampoo, with a milder one, for example, an amino acid-based anionic surfactant, an amphoteric surfactant, or a nonionic surfactant. However, these are generally more expensive than conventional products and their cleaning power is not sufficient. Also, a one-pack type having both the effects of shampoo and rinse has been proposed, and is called a rinse-in shampoo or a conditioning shampoo.

As a typical example thereof, the latest cosmetic science, revised supplement II, July 10, 1992, Yakuji Nippo Co., Ltd. (Reference 1), pages 191 to 192, prescription examples of conditioning shampoo are described. In this case, sodium alkyl sulfate is used as the main cleaning agent, and cation-modified cellulose ether is used as the conditioning agent. Further, ammonium lauryl sulfate and ammonium lauryl ether sulfate are used as the main agents for cleaning the rinse-in shampoo, and a conditioning effect can be expected. Decyloctyldimethylammonium chloride, laurylhydroxypropyl chloride (POE10 methylglycoside) ammonium, etc. are used as chemicals. All of these have high detergency and can be produced at a relatively low price, but have a high skin irritation and lack conditioning effects.

As described above, instead of using a sulfuric acid type anionic surfactant as the main detergent, an amino acid type anionic surfactant is used instead to reduce the skin irritation. 139115) has also been done,
In this case, the raw material cost is relatively high, and the foamability and cleanability are not sufficient.

It is also known that an amphoteric surfactant is used as a main cleaning agent for a rinse-integrated shampoo, and a cationic surfactant, an oil component and the like are added as a rinse agent. {Fragrance Journal 1989-10 (Reference 2) 11
Page} In this case also, the raw material cost is high, and the foamability during cleaning is
Detergency is not sufficient.

[0006] As described above, when the cleaning property is good, the conditioning effect is not sufficient, and those mild and excellent in the conditioning effect have the drawbacks of being expensive and having poor cleaning properties.

Furthermore, after washing with these shampoos, for example, the next day after washing with a normal shampoo, that is, a shampoo which does not particularly have conditioning properties (for example, transparent shampoo on page 155 of Document 1). There was a case where the hair had a dry feel due to excessive degreasing or an oily state due to insufficient washing, and in particular, the rinse-in shampoo containing silicone oil was apt to become oily.

[0008]

SUMMARY OF THE INVENTION It is an object of the present invention to produce a cleansing agent which has good foaming properties during hair washing, is excellent in detergency, and at the same time has a good conditioning effect. The raw material cost is also achieved relatively cheaply.

[0009]

Means for Solving the Problems As a result of studying various combinations of the raw materials described in various documents such as the above-mentioned Document 2 and the original raw materials possessed by the present inventors, Ken Ken or
It has been found that the above object can be achieved by containing a sulfate type anionic surfactant, a vegetable protein, a quaternary ammonium derivative of a hydrolyzate and a lanolin type substance, and the present invention has been completed.

The soap used in the present invention is a salt of higher fatty acid. Usually, glycerin produced as a by-product is removed by a salt formed by reacting oils and fats such as coconut oil, palm oil, olive oil and beef tallow with sodium hydroxide. In the case of the present invention, it may not be particularly prepared by this method, and ammonium salt, potassium salt and the like may be used.

The sulfuric acid type anionic surfactant referred to in the present invention includes alkyl sulfates, alkyl ether sulfates and α-olefin sulfonates, the details of which are described in Documents 1 and 1.
82-183. This means that alcohol, polyalkylene oxide adduct of alcohol, olefin, etc. are reacted with sulfuric acid to be sulphated (-R-OS
O ₃ M) or a sulfonated (-RSO ₃ M) salt. Here, R is an organic group having 8 or more carbon atoms such as alkyl. M is a monovalent metal or the like, which is often sodium, but may be potassium, ammonium, ethanolamines or the like. These may be blended in the detergent in only one type, but may be in two or more types. And the compounding quantity is usually about 10 to 50%.

The soap used or the sulfate type anionic surfactant used in the present invention may be blended with either one,
It means that both may be mixed at the same time.

The vegetable protein hydrolyzate of the quaternary ammonium derivative of the vegetable protein hydrolyzate of the present invention is a protein hydrolyzate of soybean, wheat, rice, corn or the like hydrolyzed with an acid, an alkali or a protease. The present invention includes all described in Japanese Patent Application Laid-Open No. 62-53909 previously filed by the present inventors. Next, the quaternary ammonium derivative is a plant hydrolyzed protein to which a group of the chemical formula ₁ is added. In this formula, R ₁ represents an adduct of the hydrolyzed protein residue and other groups, and R ₂ R ₃ R ₄ represents an alkyl group. And R ₂ R ₃ R ₄ may be the same or different.

[0014]

[Chemical 1]

An example of this quaternary ammonium derivative is:
It is described in Japanese Patent Application Laid-Open No. 63-68514 filed by the present inventors, in which a plant protein hydrolyzate is reacted with 3chloro-2-hydroxypropyltrimethylammonium salt. Instead of trimethyl, stearyl dimethyl or the like, which has a long chain with only one alkyl, is also excellent.
Also, instead of using 3 chloro-2-hydroxypropyl trimethyl ammonium salt, 2,3 epooxy propyl trimethyl ammonium salt can be reacted. The quaternary ammonium derivative of this vegetable protein hydrolyzate has less animal odor than animal ones,
Moreover, the feeling after treatment is also excellent. Further, by using a quaternary ammonium derivative, the adsorptivity to hair is increased, the conditioning effect after treatment is improved, and the effect lasts longer. The blending of the quaternary ammonium derivative of this vegetable protein hydrolyzate with a detergent is 0.
It is preferably about 2 to 5% by weight. If the amount is less than the above range, the conditioning effect is insufficient, and if the amount is too large, the solubility in the cleaning agent may be deteriorated or the cleaning property may be deteriorated. (Example: JP-A-63-68514)

There are many kinds of lanolin-based substances in this patent, but they are roughly classified as follows. (1) Lanolin (Literature 3) Liquid Lanolin (Literature 3) Hard Lanolin (Literature 3) (2) Adsorption Purification Lanolin (Literature 4) or Lanolin that does not contain an insecticide (JP-A-2-233797), the latter being adsorption purification. It can be produced by vacuum drive distillation or extraction with a solvent. (3) Lanolin derivatives, such as lanolin acetate (Reference 3), acetic acid liquid lanolin (Reference 4), hydroxylanolin (Reference 4), reduced lanolin (Reference 3), etc. (4) Lanolin fatty acid or ester thereof For example, lanolin fatty acid ( Reference 3), hard lanolin fatty acid (Reference 3), soft lanolin fatty acid (Reference 3), lanolin fatty acid isopropyl (Reference 3), lanolin fatty acid isostearyl (Reference 4), lanolin fatty acid octyldodecyl (Reference 4), lanolin fatty acid cholesteryl (Reference 4) Reference 4), lanolin fatty acid polyethylene glycol (Reference 3), etc. (5) Lanolin alcohol or fatty acid ester For example, lanolin alcohol (Reference 3), cholesterol (Reference 3), lanolin acetate acetate, cholesterol oleate, etc. (6) Not derived from lanolin Is nature, special Those whose water retention is similar to lanolin. For example, a certain amount of shea butter is left without being completely removed during purification. As a product belonging to this, there is Kropure-SR-Vegelan (Cloder Japan Co., Ltd., JP-A-2-191210). It should be noted that the above-mentioned reference 3 was written in the commentary on the second edition of the cosmetics material standard, published by Yakuji Nipposha 1984, 1989, 1991, and the reference 4 was written on Japan's general-purpose cosmetic raw material second edition, Yakuji Nippo 1989. Published on March 25th. The content of the lanolins in the detergent is preferably about 0.2 to 5%. If the amount is less than this, the conditioning effect is not sufficient, and if the amount is more than this, the cleaning effect is poor or the hair after washing has an oily feeling. When this lanolin-based substance is compounded in the detergent, it may be used alone or in combination of two or more.

Further, the conditioning effect mentioned in this patent and the feeling after the next washing are good, because the hair does not comb well and the hair does not feel dry. The hair is always moist and supple, and the curl retention is good. . The hair has a glossy appearance and a body feel. Hair is strengthened, and it is hard to break, break, or fall out. Make your scalp healthy. I mean to satisfy some of them.

This patent relates to a detergent which has both good detergency and conditioning, and which has a good feeling after the next washing. It is a soap or a sulfate type anionic surfactant and a vegetable protein quaternary ammonium derivative. Although it contains a lanolin-based substance as an essential component, other raw materials such as a surfactant, a foaming agent, a thickener, a hydrotrope, an emulsifying agent, a conditioning agent, and a high-grade agent are included unless the amount is so large as to impair its performance. Alcohol, fragrance, germicide,
It may contain a preservative, a coloring agent, a chelating agent, a pH adjusting agent and the like, and usually contains water.
