Detailed Description of the Invention

[0001]

This invention relates to the properties and usability of detergents.

[0002]

2. Description of the Related Art A detergent composition is required to have not only a cleaning effect for simply washing off sebum but also various effects such as cleaning other than sebum and usability.

For example, with regard to face wash, it is required not only to wash off sebum and the like, but also to wash off various cosmetics and the like.

For this reason, a person who has applied a makeup cosmetic containing oils such as lipstick, foundation, mascara, and eye shadow contains a large amount of an oil that is easily compatible with the makeup cosmetics as the first step when washing the face. After removing most of the makeup ingredients using a cleansing cream for cleansing makeup, such as cleansing cream, cleansing oil, cleansing milk, cleansing gel, etc., in the second step, foam soap and cleansing foam etc. to cleanse your skin. Then, the residual oil content of the cleaning agent for makeup removal used in the first step was washed off together with skin-like sebum and dirt, and a satisfactory feeling such as a refreshing feeling or a refreshing feeling was obtained.

As described above, the reason why two-step cleaning is required is that when creams and the like for removing makeup containing a large amount of oil are used, they remain on the skin even after rinsing with water or lukewarm water immediately after use. This is because the oil is not removed sufficiently, and you cannot get a clean feeling of washing, such as slimming and stickiness.
Further, this is because the pigments, colorants, etc. covered with the oil of the makeup cosmetics cannot be sufficiently removed from the skin only with the facial cleanser for bare skin washing such as soap or cleansing foam which is used while foaming.

On the other hand, in recent years, when quickness and simplicity of makeup action are being demanded, a skin cleansing agent having both a makeup removing effect and a cleansing and refreshing bare skin washing effect with only one operation is desired. It is rare.

As such a one-step skin cleansing agent,
For example, there is one disclosed in JP-A-63-122618.

[0008] However, the conventional foaming type makeup removing cosmetics have poor compatibility with makeup, insufficient foaming, and no smoothness after washing.

The cleaning effect of the cleaning agent, the high usability,
It is required not only for skin cleansers such as make-up cleansers, but also for hair cleansers.

[0010]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a cleaning agent having a high cleaning effect and an excellent feeling of use such as foaming and washing.

[0011]

The present inventor has solved such problems.
As a result of repeated studies to solve the problem, the degree of polymerization is different
Combined with polyoxyethylene diester in detergent
Find out that you can solve the above problems by doing this book
Completed the invention.

That is, the present invention provides a polyoxyethylene diester represented by the general formula 3 ( 14 ≧ n ≧ 5),
It is a cleaning agent containing a polyoxyethylene diester (n = 1 to 3) represented by the general formula 4. In the formulas below, R ₁ and R ₂ are an isostearine group and / or an oleyl group.

BEST MODE FOR CARRYING OUT THE INVENTION The cleansing agent of the present invention is preferably used as a skin cleansing agent such as a makeup cleansing agent and a body cleansing agent, and a hair cleansing agent.

As the polyoxyethylene diester used in the detergent of the present invention, those having n ≧ 5 and those having n = 1 to 3 are used in combination.

For n ≧ 5, 5 ≦ n ≦ 14 . When it is less than 5, foaming is particularly bad and it is difficult to dissolve in the system.

For n = 1 to 3, n = 1 is preferable. If n exceeds 3, the makeup becomes unsuitable and the smoothness becomes poor.

The polyoxyethylene diester of the present invention is preferably polyoxyethylene diisostearate and / or polyoxyethylene dioleate.

The amount of polyoxyethylene diester with n ≧ 5 to be added to the cleansing agent is preferably 0.1 to 15% by weight, and most preferably 2 to 8% by weight in the case of a skin cleansing agent. The same applies to the case of a hair wash. n = 1 to 1
The content of the polyoxyethylene diester of 3 in the detergent is preferably 0.1 to 10% by weight, and most preferably 2 to 8% by weight.

A surfactant, a pH adjuster, an antiseptic, a fragrance and the like are appropriately added to the detergent of the present invention.

As the surfactant used in the present invention,
For example, the following are given. Examples of the anionic surfactant include: fatty acid soap, soap base, sodium laurate, sodium barmitate, etc. ● alkyl ether sulfate ester salts POE lauryl sulfate triethanolamine, POE sodium lauryl sulfate, etc. ● higher fatty acid amide sulfonates Lauroyl sarcosine methorium, N-acyl sarcosinic acid, N-myristoyl-N-methyl taurine sodium, coconut oil fatty acid methyl tauride sodium, lauryl methyl tauride sodium, etc.Sulfosuccinates di-2-ethylhexyl sodium sulfosuccinate, Monolauryl monoethanolamide sodium polyoxyethylene sulfosuccinate, sodium lauryl polypropylene glycol sulfosuccinate, etc. ● N-acyl glutamate -Mono sodium lauroyl glutamate, disodium N-stearoyl glutamate, mono sodium N-myristoyl-L-glutamate, etc.Alkyl ether carboxylate sodium dodecyl acetate sodium ether, etc. ○ Phosphate ester salts POE oleyl ether sodium phosphate, POE stearyl ether Phosphoric acid linear dodecyl benzene sulfonic acid, etc. ○ Alkyl benzene sulfonates Sodium linear dodecyl sulfonate, linear dodecyl benzene sulfobutyric triethanolamine, linear dodecyl benzene sulfonic acid, etc. ○ Higher alkyl sulfate ester salts sodium lauryl sulfate, potassium lauryl sulfate, etc. Higher fatty acid ester sulfate ester hardened coconut oil fatty acid glycerin sodium sulfate, etc. , POE alkyl ether carboxylic acid, alkyl allyl ether carboxylic acid salt, α-olefin sulfonic acid salt, secondary alcohol sulfuric acid ester salt, higher fatty acid ester sulfonic acid salt, higher fatty acid alkylolamide sulfuric acid ester salt, lauroyl monoethanolamide succinic acid Sodium, N-palmitoyl aspartic acid ditriethanolamine and the like can be mentioned.

Examples of the amphoteric activator include: imidazoline-based amphoteric activator 2-undecyl-N, N, N (hydroxyethylcarboxymethyl) -2imidazoline sodium, 2-cocoyl-2-imidazolinium hydroxyside-1-carboxy Ethyloxy disodium, etc.-Betaine surfactant 2-Beptadecyl-N-carboxymethyl-N-hydroxyethyl imidazolinium betaine, lauryl dimethylamino acetic acid betaine, alkyl betaine, amidobetaine, sulfobetaine, etc.-Amino acid salt Examples thereof include N-lauryl β-alanine and N-stearyl β-alanine.
