Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic composition which has excellent antibacterial properties, is not contaminated by microorganisms such as bacteria and mold, is stable and has low skin irritation. More specifically, one or more selected from polyhydric alcohols and alkyl ethers of polyhydric alcohols,
The present invention relates to a hypoallergenic cosmetic composition having a high antibacterial property, which is prepared by using an extract or crushed product of Jiju, which is a kind of crude drug, in combination.

[0002]

2. Description of the Related Art Conventionally, water-containing cosmetics such as lotions, milky lotions and creams have various antiseptic and mildew-proofing agents in order to prevent deterioration due to contamination of microorganisms such as bacteria and molds during production and use. Agents have been used. Examples of such preservatives include phenols such as isopropylmethylphenol, paraoxybenzoate, phenoxyethanol and hinokitiol; benzoic acid and its salts; salicylic acid and its salts; dehydroacetic acid and its salts; sorbic acid and its salts; Quaternary ammoniums such as benzalkonium, benzethonium chloride and alkyltrimethylammonium chloride, amphoteric surfactants such as alkylaminoethylglycine hydrochloride and sodium stearylhydroxyethylbetaine chloride, and photosensitizers are used.

However, many of the above-mentioned preservatives and fungicides have been reported to have primary irritation, sensitization or photosensitization to the skin, and the amount of the preservative and fungicide is regulated based on the standard of cosmetic raw materials from the viewpoint of safety. In many cases, it is not possible to add an amount that actually shows effective antibacterial activity. Furthermore, it is known that even if the skin does not show a stimulating or sensitizing reaction such as redness, rash, or edema, it may cause discomfort such as stinging, tingling or tingling when using the cosmetic. Have been. In addition, due to the interaction with the base of the cosmetic or other compounding components, there may be cases where sufficient antibacterial activity is not exhibited.

For example, isopropylmethylphenol,
When oil-soluble preservatives and fungicides such as paraoxybenzoate and sorbic acid are added to cosmetics containing a polymer thickener or powder, the antibacterial activity is reduced due to adsorption or the like. Also,
In cosmetics containing a surfactant, the antibacterial activity is also decreased due to incorporation into the surfactant micelle. On the other hand, if a large amount is blended in anticipation of sufficient antibacterial activity, problems such as crystal precipitation at low temperatures and the like arise in product stability.

[0005] Water-soluble preservatives and fungicides such as benzoate, salicylate and dehydroacetate are not effective unless the pH of the cosmetic is weakly acidic. As the acidity increases, the solubility in water decreases, and crystals may precipitate.

Further, regarding quaternary ammonium compounds and amphoteric surfactants, skin irritation and eye mucous membrane irritation are recognized, foaming is likely to occur, and antibacterial activity decreases on the acidic side.
There are practical problems such as interaction with anionic substances. On the other hand, N-long chain acyl basic amino acid derivatives and acid addition salts thereof, which are commonly used as hydrophilic cationic surfactants, have long been known as bactericidal detergents (Japanese Patent Publication No. 51-5413). One of them is N-Cocoil-L
-Arginine ethyl ester-DL-pyrrolidone carboxylate is marketed under the trade name "CAE". However, in complex systems containing many types of raw materials such as cosmetics, the expected concentration of the compound is expected. Antibacterial effect is not obtained as expected,
When the amount was increased until a sufficient antibacterial action was exhibited, there was a problem that stability decreased.

[0007]

Accordingly, in the present invention, an effective antibacterial action is exhibited without deteriorating the antibacterial activity by the cosmetic base or other compounding components, and the antiseptic and fungicide is used as much as possible. The amount of the compound is reduced to obtain a cosmetic that not only shows no primary irritation or sensitization to the skin, but also does not cause discomfort such as stinging pain, tingling or tingling when using the cosmetic. It was intended.

[0008]

In order to solve the above problems, an antiseptic / fungicidal system having high stability and low irritation to the skin was examined, and as a result, a polyhydric alcohol and an alkyl ether of a polyhydric alcohol were selected. Not only synergistically improved antibacterial activity, but also significantly reduced irritation and discomfort to the skin by combining and combining two or more species, and an extract or crushed product of Jiju, which is one of the crude drugs To complete the present invention.

In the present invention, polyhydric alcohols which are usually used as a raw material for cosmetics can be used, but those having 4 or less hydroxyl groups in the molecule are particularly preferable for obtaining synergistic antibacterial activity. . For example, ethylene glycol, diethylene glycol, triethylene glycol,
Propylene glycol, dipropylene glycol, 1,3-
Examples thereof include butylene glycol, 3-methyl-1,3-butanediol (isopropylene glycol), hexylene glycol, glycerin, diglycerin, and the like, and one or more of them are selected and used.

As the alkyl ether of a polyhydric alcohol used in the present invention, glycols or alkyl ethers of glycerin can be preferably used.
Ethylene glycol monomethyl ether, ethylene glycol monoethyl ether (ethyl ethellosolve), ethylene glycol monobutyl ether (butyl cellosolve), ethylene glycol dimethyl ether, diethylene glycol monomethyl ether (methyl carbitol), diethylene glycol monoethyl ether (ethyl carbitol), diethylene glycol monobutyl ether , Diethylene glycol dimethyl ether, diethylene glycol diethyl ether, propylene glycol monomethyl ether, propylene glycol monoethyl ether, propylene glycol monoisopropyl ether, dipropylene glycol monomethyl ether, dipropylene glycol monoethyl ether, glyceryl monopalmityl Ether (Kimi alcohol),
Glyceryl monostearyl ether (batyl alcohol), glyceryl monooleyl ether (ceracyl alcohol), etc. are exemplified as preferable ones, and one or more of them are selected and used.

These polyhydric alcohols or alkyl ethers of polyhydric alcohols alone exhibit antibacterial activity at 50% by weight or more, but when added to complex systems such as cosmetics, sufficient antibacterial activity is recognized. Often not. However, in the present invention, synergistic enhancement of antibacterial activity is recognized, and a sufficient antibacterial action is exhibited with a compounding amount of about 5.0 to 10.0% by weight.

[0012] In the present invention, the earthworm, which is a kind of crude drug used in combination with polyhydric alcohol or alkyl ether of polyhydric alcohol, is Sanguisorba officina.
lis L., Sanguisorba tenuifolia Fisch et Link, Sangu
isorba applanata , Sanguisorba alpina ), and has been used for a long time as a hemostatic astringent. Waremokou has a hyaluronidase inactivating effect (Japanese Unexamined Patent Publication No.
1520) and antiplasmin effect (JP-A-1-6141)
5) is already known.

[0013] The ground may be used as it is, depending on the formulation of the cosmetic, but may be used as it is extracted with a solvent. As a solvent for obtaining these crude drugs and plant extracts, one or more selected from water, ethanol, 1,3-butylene glycol, propylene glycol, glycerin, and diglycerin are preferable. The ratio of groundwater to solvent at the time of extraction is not particularly limited.
The solvent is preferably 2 to 1000 times by weight, particularly 5 to 100 times by weight in terms of extraction operation and efficiency. In addition, it is convenient to set the extraction temperature within the range of room temperature-normal pressure or lower than the boiling point of the solvent, and the extraction time varies depending on the extraction temperature and the like.
It is preferable to set the time in a range from time to two weeks.

In addition, the thus-obtained ground beetroot extract can be used as it is, or it is blended after deodorizing, refining and other operations within a range that does not impair the antiseptic / antifungal action. Alternatively, a fraction may be obtained using column chromatography or the like. Furthermore, these extracts, deodorized and purified products, and fractionated products can also be made into dried products by removing the solvent from them, and further provided in the form of being solubilized in a solvent such as alcohol or in the form of emulsion. can do. The blending amount is 0.01 to 2
0.0 wt% is suitable.

[0015]

[Function] Although polyhydric alcohols and alkyl ethers of polyhydric alcohols alone show antibacterial activity in an amount of 5.0% by weight or more, they are expected when added to a complicated mixed system such as cosmetics. Often the antibacterial effect is not achieved. However, in the present invention, synergistic enhancement of antibacterial action is recognized, so one or two selected from polyhydric alcohols and alkyl ethers of polyhydric alcohols.
In a system containing 5.0% by weight or more of seeds or more, by using an extract or pulverized product of Jiyu, it is sufficient even if an antiseptic / antifungal agent such as paraoxybenzoate or 2-phenoxyethanol is not blended. An antibacterial effect is obtained, and not only irritation and sensitization to the skin but also discomfort such as stinging, tingling and tingling during use can be significantly reduced.

[0016]

BEST MODE FOR CARRYING OUT THE INVENTION The cosmetic according to the present invention is particularly useful for a system containing a large amount of water and an oil-in-water emulsion system in which the external phase is an aqueous phase. Ingredients, makeup base lotion, creamy, milky or creamy foundation, emulsified eye color or cheek color, aqueous suspension or emulsified eye liner, makeup cosmetics such as mascara, cleansing lotion, cleansing gel , It can be provided as cleaning cosmetics such as liquid soap, and hair cosmetics such as shampoo, hair rinse and hair tonic.
