BRIEF DESCRIPTION OF THE DRAWINGS It is a schematic diagram of the dispersion stability measuring apparatus used by this invention.

The present invention relates to a surface-treated ocher powder for use in cosmetics and a method for producing the same, and a cosmetic composition containing the same, and more particularly, to an ocher powder composite surface-treated with a metal salt and lecithin of N-acylamino acid. A method and a cosmetic composition containing the surface-treated ocher powder.

Many cosmetics have been developed and sold to prevent aging and maintain elastic and clean skin, but its main ingredients are chemicals, which do not satisfy various conditions of skin and have side effects. In addition, there are many products using natural substances extracted from plants, but they do not have sufficient scientific evidence and clinical trials. However, they show only a simple protective function of penetrating the skin of vitamins and some active ingredients contained in plants.

In addition, natural minerals such as ocher, mud, and jade are used, but most of them are sediments and some rocks that have settled in the sea, rivers, and rivers. This also lacks solid research and experimental results on cosmetic efficacy. In the application process, there are various difficulties in dispersibility, precipitation, storage, etc. of the main inorganic component.

Yellow soil (黄 알려진) as well known to radiate heat radiant heat is beneficial to the human body, is distributed evenly in the south central and Honam region, and refers to 100% raw soil collected 50 ~ 60 cm underground from the surface of the stratum, its components It contains eight kinds of minerals such as silver iron, carbonate, calcium, silica, magnesium, and minerals. It is not toxic and has fine particles.

In ancient books such as Dongbogamgam, Dongguk Abnormal Noodle House, and Herbal Wood, it is said that it has excellent effects on the effects of ocher on diabetes, neuralgia, hypertension, liver poisoning, diarrhea, rationale, pulmonary tuberculosis and anti-aging.

In particular, the herbaceous wood was divided into 61 species, and each of the weak soils was called ocher. Mixing ocher with toxic medicinal herbs neutralizes the toxicity, while non-toxic medicinal herbs have been documented to increase the constituent of the medicinal herb, and also to treat liver poisoning, stop bleeding, control yin and yang, and appetite. It is used as a substance beneficial to the human body, such as to strengthen the spleen and to boost.

In addition, it is a kind of ceramic that has a function of emitting natural infrared rays and far infrared rays, and it has been known for a long time that the plant's growth promotion, moisturizing effect, skin beauty effect and detoxification effect on various pollutants are known. The results have been proven through various clinical trials. In developed countries, it is widely applied to mechanical, electrical, electronic, textile, and food fields by using the far-infrared radiation function of ceramics. However, in Korea, the application technology is weak. have.

Yellow clay, which has far-infrared radiation and anion-releasing effect, is difficult to apply in the cosmetic field.

First, most ceramic materials, including ocher, tend to be precipitated in the container during manufacturing or storage due to high specific gravity, and uniform dispersion with other raw materials is difficult. Second, air hydrogen positive charge (H ⁺⁾ of the water molecules in the aqueous solution either during or hydroxyl (OH ^-) because of the formation of surface hydroxyl groups by hydrogen bonding to the oxygen present in the anion and minerals to the affinity to water is too high, a certain Application to color cosmetic formulations requiring a level of water repellency is difficult.

Therefore, the basic cosmetics are partially applied to high-viscosity formulations such as packs and creams, and in particular, low viscosity liquid products such as shampoos and body cleansers have been the biggest problem of stability due to precipitation phenomenon over time. In addition, the make-up color products have a problem in that they are easily erased by the sweat or water, or are discolored and dried due to the surface hydrophilicity of the ocher powder.

The present inventors have provided excellent long-lasting color tone cosmetics having excellent malleability and adhesion to skin using powders surface-treated with amino acids and silicone fatty esters in Korean Patent No. 043332.

Generally, water soluble N-acylamino acid salts such as Na ⁺ , K ⁺ , Li ⁺ and triethanolamine salts of N-acylamino acids are produced and marketed industrially as anionic surfactants. In addition, these water-soluble salts are widely used as basic ingredients for cleaning agents and emulsifiers, especially shampoos, soaps, and creams, and the use of water-insoluble N-acylamino acid metal salts as a surface treatment agent for cosmetic pigments and extender pigments is based on Miyoshi Japan. And is widely used in cosmetics and the like (see US Patent No. 4,606,914). The N-acylamino acid metal salt surface treatment powder has a weak acidity similar to the pH of the skin, has a function of protecting the skin, prevents drying of the skin, and dispersibility due to its strong affinity with other cosmetic pigments and oils. It is known to have various advantages such as an excellent point.

Lecithin, on the other hand, is one of the major components of the phospholipids that make up the animal cell membrane system, and has a composition similar to that of skin lipids. Phospholipids are classified into glycerophospholipids and sphingophospholipids. Phospholipids are structural elements of cell membranes, nuclei and other cytoplasmic components, are major components of the neuronal myelin layer, and are also components of the mitochondria enzyme system and are involved in protein synthesis. In brain tissues, it is a source of energy for the brain. In the blood, it is involved in the transport and absorption of fats and in blood coagulation. In general, lecithin is a phospholipid component contained in proteins such as egg yolks and legumes, and has been used in cosmetics for the purpose of skin cell regeneration and nutrition. Hydrophilic moieties such as phosphoric acid and choline are bonded to one side of glycerin, and hydrophobic acyl groups are bonded to the other side, and have amphiphilic surface activity. Thus, emulsifiers or liposomes are mainly used in food, cosmetics, and pharmaceutical fields. It is also used.

In order to solve the above problems, the present inventors have conducted research on the surface modification of ocher powder, and when the surface is treated with an appropriate amount of N-acylamino acid and lecithin, dispersibility and Not only does the precipitation become very good, but it also prevents drying of the skin even when applied to color products, and its affinity with other pigments or inorganic pigments or binder oils makes it easy to remove perspiration and water, making cosmetics with excellent durability. The present invention was completed.

Therefore, the object of the present invention is good dispersibility when applied to the basic cosmetics do not easily settle and maintain a constant for a long time, excellent color expression power and persistence when applied to the color cosmetics and prevents the sultry of the raw ocher powder is unpleasant It is to provide a surface-treated ocher powder exhibiting a moist feeling and a method for producing the same.                         

Still another object of the present invention is to provide a cosmetic having excellent stability and durability using ocher powder surface-treated with the amino acid / lecithin.

The present invention relates to ocher powder surface-treated with a metal salt of N-acylamino acid and lecithin.

In addition, the present invention comprises the steps of adding a water-soluble salt of N-acylamino acid to 0.1 to 10% by weight of the powder to the ocher powder suspended in water;

Coating the N-acylamino acid metal salt on the surface of the ocher powder by dropwise adding the water-soluble metal salt to 0.6-2.0 times the number of moles of the N-acylamino acid water-soluble salt; And

It relates to a method for producing a composite surface treated ocher powder consisting of re-coating lecithin to 0.1 to 10.0% by weight of the powder.

The clay according to the present invention is 58 to 65% by weight of silica (SiO ₂ ), 13 to 18% by weight of alumina (Al ₂ O ₃ ), 5 to 7% by weight of iron oxide (Fe ₂ O ₃ ), 1 to 3 weight % Magnesium oxide (MgO), 1-3 wt% sodium oxide (Na ₂ O), 0.5-3 wt% potassium oxide (K ₂ O), 0.5-3 wt% titanium dioxide (TiO ₂ ), 3 It consists of ˜7 wt% calcium oxide and 0.3-1.0 wt% manganese oxide (MnO).

The ocher crystal structure has a layered structure, and in particular, a three-layered structure in which one octahedron composed of a combination of Al and O is formed between a tetrahedral layer composed of two aluminum (Al) and oxygen (O) bonds. It is a type 1 structure.

The amino acid used in the present invention may be selected from the compounds of the following Chemical Formulas 1 to 3 described in Korean Patent No. 034332.

Wherein RCO represents a residue derived from capric acid, lauric acid, myristic acid, palmitic acid, stearic acid or oleic acid, and M represents an aluminum atom, a magnesium atom, a calcium atom, a zinc atom, a zirconium atom or a titanium atom K is an integer of 1-3, l is an integer of 1-2, m shows the integer of 1-4.

N-acylamino acids which are precursors of the N-acylamino acid metal salts represented by the above formulas include N-acyl-N-methyl-glycine, N-acyl-N-methyl-β-alanine and N-acyl-L-glutamic acid. Among them, it is particularly preferable to use N-acyl-L-glutamic acid.

The chemical structure of the lecithin used in the present invention may be represented by the following formula (4), and stearic acid, palmitic acid or oleic acid diglyceride is composed of phosphatidyl choline (L-α-phosphatidyl coline) structure bonded to phosphate choline ester. In addition, these [-PO (OH) OCH ₂ CH ₂ N ⁺ (CH ₃ ) ₃ ] group and the hydroxyl group [-OH] on the surface of the ocher powder adhere to the surface of the powder. On the other hand, lecithin can be classified into hydrogenated (hydrogenated) lecithin and non-hydrogenated lecithin according to its structure. Hydrogenated lecithin has been widely used in cosmetic formulations for stabilization of the formulation because of less color discoloration and odor.

Here, R ₁ and R ₂ represent a hydrogenated alkyl group.

The lecithin-coated powder exhibits a creamy cushioning with a very soft and moist feeling due to the diglyceride structure substituted with stearic acid, palmitic acid or oleic acid having a long hydrocarbon chain.

Looking at the manufacturing method of the amino acid / lecithin surface treatment ocher powder according to the present invention in more detail.

First, in the first step, the ocher powder is mixed with water and stirred to form a slurry having a slurry state of about 5 to 30% by weight. N-acylamino acid water-soluble salt is added to this suspension by 0.5 to 10%, preferably 0.5 to 3% by weight of the powder, and stirred to form a uniform slurry. While continuing to stir this slurry, the water-soluble metal salt equivalent to 0.6-2.0 times, preferably 1-1.2 times the number-of-moles of the already-added N-acylamino acid water-soluble salt is slowly added dropwise.

As the water-soluble metal salt is added as described above, the N-acylamino acid water-soluble salt reacts with the water-soluble metal salt of Al, Mg, Ca, Zn, Zr and / or Ti to form a fine particle N-acylamino acid metal salt, Adsorbed on the surface sequentially. After completion of the addition of the water-soluble metal salts of Al, Mg, Ca, Zn, Zr and / or Ti, stirring is continued for about 10 minutes and then left to stand for about 1 hour or more to mature. Next, the solids are filtered and washed with a centrifuge, a vacuum filter, or the like and sufficiently dried at about 80 to 150 ° C. The dried solid is crushed into individual particles using a grinder such as an atomizer to prepare amino acid surface-treated ocher powder.

Next, in step 2, the surface of the amino acid surface treatment ocher powder is coated with lecithin. That is, the amino acid surface treatment powder prepared by the above method is placed in a mixing grinder such as a Henschel mixer and continuously stirred and mixed while spraying and adding a lecithin solution which is dissolved in a solvent such as ethanol, isopropyl alcohol, acetone or volatile silicone with a spray. While sufficiently mixing to uniformly coat the surface of the lecithin and then hot air dried at about 80 ~ 95 ℃ to stabilize the coating to prepare the amino acid / lecithin composite surface treatment ocher powder of the present invention. The treatment amount of lecithin is in the range of 0.1 to 10%, preferably 0.5 to 3%, based on the weight of the ocher powder before treatment, and preferably 0.5 to 2 times the amount of amino acid treatment.

If the amount of lecithin is too small compared to the amount of amino acid, it is difficult to impart physical properties such as skin adhesion strength, dispersibility in aqueous solution, soft and moist feeling, etc., and if too much, the amino acid is completely wrapped to coat the amino acid so that the amino acid can be properly provided. It becomes impossible.

As described above, the method for preparing the composite surface-treated ocher powder of the present invention can be prepared by a method of simultaneously surface-treating amino acids and lecithin. For example, lecithin may be added to the surface of the powder by adding lecithin in the aqueous slurry during the production of the amino acid-treated ocher powder in the first step. In this method, the N-acylamino acid metal salt may be added during the formation and adsorption reaction to cause the amino acid and the lecithin to adhere to the ocher powder at the same time, or may be added after the amino acid surface treatment is completed to coat the surface again.

The present invention also relates to a cosmetic composition containing the ocher powder surface-treated with the metal salt of N-acylamino acid and lecithin, and the content of the ocher powder is preferably about 0.01 to 50.0% by weight based on the total weight of the cosmetic composition. The cosmetic composition according to the present invention can be formulated into a foundation, color tone, hair and body cosmetics.

Hereinafter, the present invention will be described in more detail with reference to Examples and Test Examples. However, these examples are intended to illustrate the present invention, it is obvious to those skilled in the art that the scope of the present invention is not limited to these examples.

Each product of the Aged Formulation and Comparative Formulation Examples was placed in a centrifuge test tube (length 12 cm), each 10.0 g, adjusted to a height of 9 to 10 cm, and then placed in a centrifuge (Korea Hanil Motor, model name: MF-550). . After centrifugation at 3000 rpm for 5 minutes, the sedimentation state of the ocher powder in each contents was observed. Dispersion stability evaluation of each sample was evaluated in five stages in which ocher powder was completely settled at the lower end of the cosmetic formulation as 1, and dispersibility in the cosmetic was maintained at 5 as no sedimentation was observed at the lower end. The results are shown in Table 10.

As shown in the experimental results, it was found that the dispersion stability of the formulations of the formulations 1 to 3 containing the amino acid / lecithin-coated ocher powder was superior to the cosmetic formulations of the comparative formulations 1 to 3 that contained the raw ocher powder uncoated. It can be seen that it is more effective in the low viscosity shampoo or rinse. The reason why the dispersion stability results of Comparative Formulation Example 1 are relatively high in Table 10 is that the formulations of Formulation Example 1 and Comparative Formulation Example 1 are high viscosity formulations with little fluidity as foam cleansing.

(5-2) Review of Two-Way Cake of Formulation Example 4

For each of the two-way cakes prepared according to Formulation Example 4 and Comparative Formulation Examples 4-1 and 4-2, four items, such as skin adhesion, sustainability, moist feeling (moisture), and overall feeling of use, were 25-35 year old women. After the comparative evaluation questionnaire was conducted for 50 people, the results are shown in Table 8. For reference, in the following, the overall feeling of use is evaluated for giving a smooth and soft feeling.
