Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic composition containing a salt in its formulation, and more particularly to a massage agent containing a spherical salt having a specific particle size and having extremely low irritation and damage to the skin.

[0002]

2. Description of the Related Art In cosmetics for cleansing or massaging, various water-insoluble particles are usually blended in order to enhance their cleaning effect and massaging effect. This is to apply a cosmetic to the skin, to suppress the irritation and damage to the skin due to the friction between the water-insoluble particles and the skin, and to impart a smooth and refreshing feeling of use, At this time, it is said that it is preferable to use the water-insoluble granular material to be blended in the cosmetic material in a spherical shape. On the other hand, water-soluble inorganic salts activate the metabolic activity of the human body,
It is said to be very good for health and beauty.For example, application of an inorganic salt to the skin improves blood circulation, which makes it easier for waste products to come out of the body and has the effect of emulsifying and removing skin fat and secretions. In addition to smoothing the skin, it also has a good moisturizing effect by preventing sweat evaporation, so it is known to be effective in healing cold sensation and rheumatism, and also effective in preventing arteriosclerosis and hypertension. . From both of the above aspects, there has been a conventional technique of rubbing a salt of crystalline grains, which is a water-soluble inorganic salt, on the body and massaging it.

[0003]

However, in the case of cleansing or massaging cosmetics containing a large number of commercially available salts, the salt granules incorporated therein have a dice-like cubic crystal shape. However, there was a problem that the irritation to the skin during use was too strong and sometimes the skin was damaged.

[0004]

In view of the above circumstances, the inventors of the present invention have as a result of earnest research, and as a result, have a particle size of 0.01 to 1.0 consisting of sodium chloride and / or potassium chloride in the formulation.
Granular spherical salt of mm, that is, by blending a spherical salt, when applying a cleansing or massage cosmetic to the skin, irritation to the skin due to friction between the granules and the skin,
The inventors have found that a cosmetic that suppresses damage and gives a smooth and refreshing feeling of use can be obtained, and arrived at the present invention.

The spherical salt used in the present invention is obtained by contacting spherical particles of ordinary dice-shaped cubic crystals in a flame of a burner and in high-temperature gas to make them spherical, and the present inventors filed a patent application on the same day. It is manufactured by the method described in No. 7-.
According to this manufacturing method, particles of a salt consisting of sodium chloride or potassium chloride having a particle diameter of 0.01 to 1.0 mm are suspended in a flame of a combustion burner or 800 ℃ or more, preferably 1,00
It is contacted with a high temperature gas of 0 to 1,300 ° C. for a short time, preferably 0.1 seconds or more, and the salt particles are partially melted and spheroidized by the surface tension of the particles and solidified by cooling to produce salt particles close to a true sphere. be able to.

The fuel for flame or high temperature gas formation in the above manufacturing method may be liquid fuel or gas fuel,
A clean fuel is suitable as much as possible, and a gaseous fuel such as natural gas, propane gas, butane gas is preferably used. If the contact time of the salt particles with the high temperature gas is insufficient, or if the temperature of the high temperature gas in the furnace is as low as 800 ° C or lower, the salt particles should be of a relatively small size, for example, about 0.01 to 0.1 mm. It is not spheroidized and the yield of spherical salt is poor. The spherical salt produced in this manner has less contact between particles, exhibits a free-flowing property, and has crystal grains that are hard to consolidate, and thus it has become possible to be suitably used in a wide range of industrial fields. Since it is excellent in preventing caking during storage, it has been considered to be used in various fields such as table salt for seasoning with excellent sprinkling properties and cleansing salt that is easy to remove. As a result of further diligent research, the present inventors have found that the particle size of sodium chloride and / or potassium chloride obtained by the above method is 0.01 to
When 1.0 mm of spherical salt was added to a cosmetic composition for cleansing or massage as a scrubbing agent for rubbing dirt on the skin groove to give an appropriate skin irritation, it was found that further properties can be utilized, and the present invention Reached

[0007]

That is, the present invention is characterized by containing a spherical salt composed of sodium chloride and / or potassium chloride having a particle diameter of 0.01 to 1.0 mm, which is remarkably low in irritation and low damage to skin. The present invention relates to cosmetics for cleansing and massaging. The cosmetics described here mean a massaging agent containing crystalline salt for the body and face as a main component, or a pasty massaging agent. The size of the spherical salt used in the present invention varies slightly depending on the type of cosmetic, but spherical particles having a particle size of about 0.01 to 1.0 mm are convenient. Particles smaller than this are not practical because the yield of spherical salt products is poor, and particles larger than this are not suitable as a massage agent because they give a feeling of discomfort to the skin during use. The amount of the spherical salt used in the present invention in the cosmetic varies depending on the type of the cosmetic, but 10 to 100% by weight of the total cosmetic composition, and 50 to 80% by weight in the case of a pasty massaging agent are used. Is good. If the content of the spherical salt is less than 10% by weight, the cleaning effect, the peeling effect and the massage effect cannot be obtained. In the case of the paste type massage agent, if the content is 80% by weight or more, the creamy or paste type does not appear. , Not preferable.

As the spherical salt in the present invention, water-soluble inorganic salts other than sodium chloride and potassium chloride, such as sodium sulfate, calcium sulfate, magnesium sulfate, sodium carbonate, sodium bicarbonate, calcium chloride, magnesium chloride, etc. You may mix. In order to add a spherical salt to a cosmetic base material, glycerin, water, and a guar gum or xanthan gum thickener are mixed to give a paste form, and a homogenizer or a dispersion kneader such as a stirrer is used. It can be used as a cosmetic material.
In addition, for the purpose of adjusting the hardness, viscosity, and fluidity of cosmetics,
Although water is included in the cosmetics, considering the usability as a massage agent, it is recommended to add it as an aqueous solution of an inorganic salt, preferably a saturated solution, and about 0 to 25 parts per 100 parts by weight of the water-soluble inorganic salt. Is desirable.

[0009]

The cosmetic containing the spherical salt of sodium chloride and / or potassium chloride having a particle size of 0.01 to 1.0 mm according to the present invention has a peeling effect of the spherical salt blended therein,
Dirt in pores that cannot be removed with soap alone, old stratum corneum,
By removing sebum and the like, and by its massage effect, it improves circulation of blood and at the same time promotes metabolism of the skin, so that the preventive and therapeutic effects of spots can be expected. Further, since it is angular with cubic cubes, it does not excessively irritate the skin like conventional salt particles and in some cases does not damage the skin, and the spherical salt of the present invention is close to a true sphere. Since it is a spherical salt particle, it has the effect of giving the skin a gentle, smooth and refreshing feeling. Further, the cosmetic of the present invention is a natural material called salt, which is spheroidized into a molten or semi-molten form, and therefore can be said to be a natural product and a cosmetic that matches the trend of safety-oriented times.
