Description

Cosmetic composition for foot care {Cosmetic compositions for foot care}

The present invention relates to a cosmetic composition for foot care only. More specifically, the first cosmetics containing a sodium polyacrylate polyacrylic acid copolymer and a spherical polymer swell in an aqueous solution to maximize the massage effect, thereby relieving edema of the foot or calf through the action of promoting blood circulation in the body part. And to facilitate the removal of keratin, while the second cosmetics to sterilize microorganisms or the like contaminated with the foot relates to a cosmetic composition dedicated to the foot care to remove the smell of the foot.

In general, cosmetics refers to an article used by painting, spraying or the like in order to clean or beautify the human body and keep skin or hair healthy, and has a slight effect on the human body. However, the skin of the human body varies depending on various factors, such as individual, site, season, age, etc. Products suitable for the purpose of use, such as detergents, lotion, emulsion, cream, gel, massage cream, Various products such as essences are available on the market, most of which are for face, hand and whole body products.

Recently, along with the development of science and technology and economic abundance, cosmetics suitable for the characteristics of each part of the body, namely around the eyes, the neck, the chest, the legs, and the development products are also commercially available. By the way, the most vulnerable part of the human body so far, the skin is not receiving the care, especially the blood circulator is called the second heart that absorbs the shock from the outside, balance and leverage Concentrated and socially active modern people often concentrate blood on their feet and calves.

Normally, the blood sent from the heart passes through the lower limb arteries through the legs and again through the veins. From here, the microcirculation of the calf causes the blood to circulate through the contraction and relaxation of the venous blood vessels. However, people who stand for long periods of time or live in stocks, especially those with a lot of social activity, will often have blood on their feet.

In this case, blood circulation is not smooth, so blood is collected in the leg vein, so the pressure of the blood vessel is increased, the vein is widened, and a fine venus pump is opened to prevent blood backflow. The blood becomes stagnant. When the blood is stagnated, the blood pressure of the veins goes up and the serous fluid in the blood leaks to the tissues around the blood vessels. In this case, the concentration of the serous fluid increases in the tissues, resulting in swelling of the legs and feet, which is called edema.

It is desirable to relieve this condition to promote blood circulation through proper massage, and the usual massage products are creams, oils, and lotions, which retain the function of providing lubricious oils so that they can be easily applied to the skin. I did.

Disadvantages of these products include the inability to raise or lower the temperature of the blood vessels in order to induce blood vessel contraction and swelling during massage, and to leave a slippery oil on the skin after use. There are some inconveniences.

Unlike general cosmetics, these foot care products require several functions, that is, the skin at the bottom of the foot has a strong moisturizing function because there are no hair follicles and sweat glands. The effect should be excellent, and because it is easy to be contaminated by microorganisms, the antiseptic sterilization function should also be excellent while having excellent use without stickiness or oil.

Looking at the patents proposed in this respect, US Pat. No. 5,556,8181 and 45,50035 describe the odor of the foot in which a cosmetic agent comprising a softener, a fragrance and an absorbent powder, a deodorant, such as talc, zeolite, soy protein, borax, silica, and starch, is used. It is proposed to remove and moisturize, but it is not very moisturizing function and bad feeling, that is, it is not suitable as a foot care cosmetic because it has a disadvantage that it is not quickly absorbed on the skin and has a lot of stickiness.

EP 489524 proposes that emulsions containing polymer composites and polyacrylates have excellent moisturizing effects as foot care cosmetics, but this also has limitations in improving dry skin of the feet.

In addition, although World Patent No. 95128849 proposes that the composition based on the starch, which is a polymer material, is excellent in feeling as a foot care cosmetic, it has little function as a foot care cosmetic except that it is not sticky and neat, so it is recognized as a foot care cosmetic. it's difficult.

U.S. Patent No. 5,099,32 proposes a cosmetic using a fine porous powder, but also does not solve the fundamental problems such as dryness of the skin of the skin and preservation of microorganisms.

In Japanese Patent No. 81133434, an antiseptic agent derived from an undecylenic acid is applied, but it does not have the function as the above-mentioned foot care cosmetic.

Accordingly, it is an object of the present invention to solve various problems of the prior art and to provide a foot care-only cosmetic having excellent functions as a foot care-only cosmetic.

The present inventors earnestly studied foot care cosmetics as a first agent, as a first agent, swelling in aqueous solution to maximize massage effect, sodium polyacrylate polyacrylic acid copolymer, moisturizing polyol, spheroidal polymer scrub having an exfoliating effect It can promote the blood circulation and reduce the edema by combining the cold and hot massage, and as a second agent, triclosan, erythromycin, salicylic acid, imidazolidinyl urea, which sterilize microorganisms and bacteria contaminated with the foot, And one or more sterile preservatives selected from the group consisting of phenoxyethanol and one or more electrolytes selected from the group consisting of sodium chloride, potassium chloride, alum, and alpha hydroxy acids to disrupt the sodium polyacrylate polyacrylic acid copolymer. Sustainable Foot Care We have developed a soluble cosmetic.

The first agent of the present invention may contain an essential oil having an aromatic effect and a surfactant having a dissolving action thereof. The second agent may also contain electrolytes such as sodium chloride, potassium chloride, alum and the like.

Sodium polyacrylate polyacrylic acid copolymers used in the present invention are characterized as polymers having the following general formula or aggregates of polymers which quickly absorb moisture when hydrated in aqueous solution and change into a soft jelly phase.

Although m and n which show a polymerization degree are not specifically limited, Usually, since polymerization degree of about m + n = 30-500 is hydrated in water, it is suitable because it is not sticky or hard in the rate or usability of hydration. M + represents a metal ion, and generally corresponds to a metal of monovalent ion. Examples thereof include Na + and K +.

Polyol refers to molecules having abundant OH groups such as glycerin, propylene glycol, 1,3-butylene glycol, dipropylene glycol, etc., which provide a moisturizing effect, and may be used alone or in combination of two or more thereof.

As spherical polymer scrub, it is a polymer such as polyethylene, polyacrylamide, polyacryl vinyl polymer, etc. It is spherical, not limited to the kind, degree of polymerization and combination ratio of the polymer. Its size can be various sizes from 0.1mm to 1mm. Can be. The scrub agent may be formulated to be a solid or porous spherical form of a general form having a massage effect and an exfoliating effect.

Essential oils with an aromatic effect are natural oils that are effective in smelling and relaxing the mind. These are not limited to specific oils.

As surfactants for dissolving such essential oils in an aqueous solution, various crab surfactants such as hydrophilic ilkylethylene, alkyl sorbitan, and alkyl ethers may be used alone or in combination of two or more thereof. It is not limited to.

The fungicide may contain one or two or more of those having a bactericidal effect such as trichromic acid, erythromycin, salicylic acid, imidazolidinyl urea, and phenoxyethanol.

As an electrolyte capable of disrupting the hydrated sodium polyacrylate polyacrylic acid copolymer gel, one or two or more thereof may be used as sodium chloride, potassium chloride, alum, alpha hydroxy acid, or the like.

The method of use is to put the first agent in water, gel it, and then massage it to promote blood circulation so that edema can be alleviated.The second agent is added to disintegrate the gel and contain the second agent. It allows you to sterilize.
