Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a massage cosmetic having a blood circulation promoting effect, and more particularly to a massage cosmetic having various feelings of use and good storage stability.

[0002]

2. Description of the Related Art Generally, massage cosmetics are those which, when applied to the skin and massaged, promote blood circulation, prevent skin aging, and adsorb and remove skin waste products. Conventionally, massage cosmetics have been proposed, for example, by adding a scrubbing agent, which has an effect of removing old keratin and the like (Japanese Patent Laid-Open Nos. 60-152407 and 63-63). 23800
No. 8, JP 51-121530 A, JP 5
8-192814, etc.).

Further, since the inorganic salt has an action of activating the metabolic activity of the human body, for example, a massage makeup in which an inorganic crystalline salt is blended or the inorganic salt is dissolved in cosmetics to enhance the massage effect. Fees have also been proposed (for example, JP-A-63-150216 and JP-A-63-27).
5508, JP-A-3-123732, etc.).
Further, it has been proposed that a polyhydric alcohol such as glycerin is blended, and the massage effect is enhanced by dehydrating and washing the skin exothermically (Japanese Patent Laid-Open No. 3-1237).
32 publication).

[0004]

However, although the conventional massage cosmetics have a blood circulation promoting effect,
There were drawbacks in terms of usability, such as stickiness, poor moisture retention, and difficulty in washing off. In addition, for example, when an inorganic salt crystal such as sodium chloride is blended, the inorganic salt crystal precipitates over time, so that storage stability is poor and formulation is difficult.

[0005]

[Means for Solving the Problems] In view of such circumstances,
The present inventors have conducted intensive studies to solve the above-mentioned drawbacks and problems of conventional massage cosmetics, and as a result, have found that nonionic surfactants having HLB of 10 or more, polyhydric alcohols, oils, water and chloride It has been found that by blending sodium granules in a specific ratio, a massage cosmetic having a high blood circulation promoting effect, an excellent feeling of use such as stickiness and washability, and good storage stability can be obtained. Has been completed.

That is, the present invention is based on the total amount of cosmetics, 1 to 30% by weight of an HLB of 10 or more nonionic surfactant, 1 to 80% by weight of polyhydric alcohol, 1 to 60% by weight.
The present invention provides a massage cosmetic composition containing the oil component (1), 1 to 20% by weight of water, and 0.5 to 50% by weight of sodium chloride granules.

Examples of the nonionic surfactant having an HLB of 10 or more include polyoxyethylene sorbitan fatty acid ester, polyoxyethylene hydrogenated castor oil, polyglycerin fatty acid ester, ethylene oxide derivative of glycerin fatty acid ester, and ethylene oxide of propylene glycol fatty acid ester. Examples thereof include derivatives, polyethylene glycol fatty acid esters, polyoxyethylene alkyl ethers, polyoxyethylene alkylphenyl ethers, and the like. These surfactants are used singly or in combination of two or more kinds in an amount of 1 to 30% by weight, preferably 1 to 20% by weight, based on the total amount of the cosmetic. If the blending amount is less than 1% by weight, the storage stability is poor, and conversely, if the blending amount is more than 30% by weight, the composition tends to become sticky and does not give a good usability.

The polyhydric alcohol includes, for example, propylene glycol, 1,3-butylene glycol, glycerin, dipropylene glycol, polyglycerin, sorbitan, glucose, trehalose, maltitol, polyethylene glycol and the like, particularly propylene glycol, 1,3-butylene glycol and glycerin are preferable. These polyhydric alcohols are used singly or in combination of two or more, and are mixed in a ratio of 1 to 80% by weight with respect to the total amount of the cosmetic. In particular, it is preferable that the content is 20% by weight or more, because a warm feeling can be given during use. If the blending amount is less than 1% by weight, the storage stability becomes poor, and conversely, if the blending amount is more than 80% by weight, the composition tends to be sticky and does not give a good usability.

The oil component may be one commonly used in cosmetics and pharmaceuticals. For example, hydrocarbons, higher alcohols, higher fatty acids, esters of higher alcohols and higher fatty acids, animal and vegetable oils and fats, cholesterol fatty acid esters. And the like. These oil components are used singly or in combination of two or more kinds in an amount of 1 to 50% by weight based on the total amount of the cosmetic. If the blending amount is less than 1% by weight, storage stability is poor and moisturizing feeling cannot be obtained. On the other hand, if the blending amount is more than 50% by weight, the wash-out property becomes poor.

Water is blended in a proportion of 1 to 20% by weight with respect to the total amount of cosmetics.

The sodium chloride granules have a particle size of 0.05 to 2.0.
Those having a particle size of 0 mm are preferably used, and are mixed in a proportion of 0.5 to 50% by weight with respect to the total amount of the cosmetic. The sodium chloride granules are substantially pure sodium chloride crystals or sodium chloride crystals containing 99% or more of sodium chloride, or JP-A-1-18.
The sodium chloride particles used in the present invention are in the form of crystals of sodium chloride containing an anti-inflammatory agent, a dye and the like disclosed in No. 1762, and the sodium chloride particles may be used alone or in combination of two or more kinds. Good.

The massage cosmetic of the present invention can be produced according to a conventional method, and in addition to the above essential ingredients,
Depending on the form of cosmetics and the body parts used, pigments,
Conventionally known additive components such as antioxidants, ultraviolet absorbers, and fragrances can be added within a range that does not impair the effects of the present invention.

EXAMPLES The present invention will be described more specifically below by showing Examples and Comparative Examples of the present invention, but the present invention is not limited to these Examples.

Examples 1 to 5 and Comparative Examples 1 to 5 Various massage cosmetics were prepared by stirring and mixing the components shown in Table 1 according to a conventional method.

[0015]

[Table 1]

Evaluation of massage cosmetics: 10 healthy people in their 20s to 40s (5 men, 5 women)
In, the sensory evaluation of the massage cosmetics of Examples 1-5 and Comparative Examples 1-5 was performed. The results are shown in Table 1. The evaluation method is that the test subject has about 10 g of massage cosmetics on the abdomen.
After applying and massaging 20 times each, the product was rinsed with warm water, and sensory evaluation was performed with respect to blood circulation promoting effect (massage feeling), stickiness, rinsing ease, and moisturizing sensation. For each item, 7 or more out of 10 were evaluated as good, and 5 or 6 out of 10 were evaluated as good, 1
The case where 4 or less out of 0 people evaluated as good was set as x. Regarding the storage stability, after standing at 40 ° C. for 1 week, the case where the precipitation of crystals and the separation of the base were not observed by visual inspection was ○, and the case where the precipitation of the crystals and the separation of the base were recognized. It was set to x. As for the comprehensive evaluation, when the sensory evaluation / storage stability had one or less Δ, it was marked with ◯, and when Δ was two or more or there was ×, it was marked with x.
