Description

Manufacturing method for hypoallergenic natural cosmetics {Manufacturing method skin cosmetic}

The present invention relates to a method for manufacturing natural cosmetics with excellent cleansing and moisturizing effects, and more specifically, by inducing to further decompose the colloidal particles in the composition by high-speed agitation, thereby inducing Brownian motion to be active and washing effect. And a method for manufacturing natural cosmetics having excellent cleansing and moisturizing effects capable of greatly improving the moisturizing effect.

Most people respond easily to sunlight during the growing season, but as skin tissue gradually changes with age, wrinkles caused by sunlight, thickening of the skin, sagging of the skin, loss of skin elasticity, roughening of the skin, A phenomenon such as dryness of the skin or staining of the skin occurs. The term collectively known as the result of the accumulation of these effects of sunlight is photoaging. This skin photoaging can be said to be a phenomenon in which the epidermal and dermal tissues change due to sunlight, and the skin becomes yellowish, thickened, and elasticity gradually decreases in the skin where the ability to respond to light is weakened.

On the other hand, as the overall culture level improves, the consumers' desire for beauty is also increasing. As the awareness of the effects of skin photoaging and pollution on the skin is spread as described above, functions such as moisturizing and supplying nutrients, alleviating and improving skin wrinkle formation beyond the skin beautification level, whitening effect, sunscreen effect, defense against pollution substances, etc. There is an increasing demand for functional cosmetic products having, and in fact, most companies are actively researching functional products.

Examples of formulations that may be provided with a moisturizing, anti-wrinkle or whitening function among cosmetic products are typical skin care products such as skin, lotion, and cream, and makeup cosmetics for skin defects such as skin beautification or blemishes and freckles by coloring. Product groups and the like.

On the other hand, facial cleansing and cleansing are the initial stages of the beauty system and are very important cosmetic acts. Removing excess sebum or makeup cosmetics cleanly and proceeding to the next treatment step is a necessary condition to prevent skin trouble and protect healthy skin condition. There are both endogenous and exogenous dirt on the target skin.

As an endogenous substance, there are excess sebum, metabolites such as keratin in the stratum corneum, and exogenous substances such as dust and dust and makeup cosmetics.

When sebum and makeup cosmetics are left and oxidized, it causes inflammation, edema, and pigmentation.

Or because microorganisms multiply and cause acne to keep the skin clean.

It is important.

Accordingly, there are various products as cleansing cosmetics that cleanse the skin, and it is known that there are creamy, latex, liquid, and powdery shapes. If this is classified into a prescription composition, an aqueous cleansing cosmetic containing an aqueous component as a main component and a surfactant as needed, an emulsifying cleansing cosmetic containing an aqueous component, an oily component, and a surfactant, and an oily component as the main component, if necessary There are oil-based cleansing cosmetics containing surfactants, and powder-like cleansing cosmetics containing hydrophilic surfactant powders and enzymes. In addition, it can be classified into emulsion type, oily type or aqueous type.

Cleansing lotions and creams are typical emulsion types, and they are known to have excellent cleansing effect on makeup by using 20 wt% to 70 wt% of oily ingredients, and excellent softness and massage effect when used. However, this type of emulsion needs to be wiped off with a tissue off because oil remains on the skin after use due to the use of a large amount of oil, so it must be wiped off with tissues, and there is a risk of skin irritation caused by physical irritation and remains even after wiping with tissues Due to its oily feeling, it has the inconvenience of having to wash face using foam cleansing or soap.

In addition, the aqueous type of cleansing gel can be divided into a microemulsion gel type using a large amount of nonionic surfactant and a large amount of oil and a cleansing gel type using anionic surfactant, which has a surfactant content of 10 wt% to 40 It is compounded relatively much by wt%. The microemulsion gel type that uses a large amount of oil contains a large amount of oil and a surfactant, so it has excellent cleansing power, but has a stiff feeling to use, and since the oil remains on the skin after use, it is difficult to wash it thoroughly with water. On the other hand, the cleansing gel type using an anionic surfactant does not use oil, but uses an anionic surfactant, so it can be easily rinsed with water and refreshed even when used, but has makeup. Therefore, in order to improve the disadvantages of usability that flows from the hand, an oily gelling agent such as organic bentonite, hydrophobized silicic acid, silicic anhydride, dextrin fatty acid ester or the like (Japanese Patent Application No. 62-108806) or aerosol formulated with dextrin fatty acid ester Made in the form of a mousse (Japanese Patent Publication No. Hei 7-277954), or using a wax such as polyethylene oil-based solid cleansing agent (Japanese Patent Publication No. 2001-213726, Korea Patent Application No. 10-2005-0090201, Korea) Patent Application No. 10-2007-0080644).

However, since the above-mentioned wax or oily gelling agent has excellent adhesion on the skin, it is difficult to obtain a refreshing feeling because it leaves a sticky and greasy oily feeling when wiped or washed after use. In addition, since it is a synthetic raw material derived from petroleum, there is a possibility of skin trouble if it remains on the skin, and it does not fit into the current well-being trend that favors products derived from nature. In addition, the surfactant used in the current oil-based cleansing cosmetics uses a surfactant made by adding polyethylene glycol, which has the effect of being washed well in water, but has excellent emulsifying power while penetrating into the skin. It has the shortcomings that it is easy to irritate the skin and excessively remove the sebum, causing dry skin.

Therefore, while improving the cleansing and massage effects, it is effective in preventing skin aging and wrinkles, and there is a need for the development of natural cosmetics without irritation to the human body.

In order to solve the above-mentioned problems, the present invention is to cleanse the colloidal particles in the composition by high-speed agitation to further decompose the colloidal particles, thereby actively inducing the Brownian motion to significantly improve the cleaning and moisturizing effects. And it is to provide a method for producing natural cosmetics excellent moisturizing effect.

The problems to be solved of the present invention are not limited to those mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the following description.

2 is a photograph of changes before and after washing.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings and the contents described below. However, the present invention is not limited to the embodiments described herein and may be embodied in other forms. Rather, the embodiments introduced herein are provided to ensure that the disclosed contents are thorough and complete and that the technical spirit of the present invention is sufficiently conveyed to those skilled in the art. 1 is a block diagram showing each step of the natural cosmetic manufacturing method excellent in cleansing and moisturizing effect according to the present invention.

Referring to Figure 1, the natural cosmetic preparation method excellent in cleansing and moisturizing effect according to the present invention largely S1 step to prepare a vegetable fatty acid, and S2 step to prepare a colloidal mixture by high-speed stirring the vegetable fatty acid, and a colloidal mixture It can be made in S3 step of ultra-high-speed agitation of colloidal particles.

In the present invention, it is characterized in that the particles in the composition are activated by browning at a high speed, thereby improving the cleaning effect by vigorously performing Brownian motion.

Brownian motion is a phenomenon in which colloidal particles having a diameter of about µm in a fluid (gas or liquid) and molecules of a dispersion medium in solution collide with colloidal particles irregularly while performing molecular motion.

The present invention uses the principle that when lecithin is added to a vegetable fatty acid, a part of the molecular structure of the fatty acid is cut. In addition, if a surfactant and an emulsifier are added to the fatty acid containing lecithin and rotated at a very high speed, the molecular structure is changed into a colloid having a size of several µm. As these colloidal particles undergo brown movement in the cosmetics, the cleaning power is greatly improved because they freely move irregularly without physical force from outside through active contact with the object to be cleaned.

More specifically, in step S1 of the present invention, 100 parts by weight of soybean oil, 20 to 50 parts by weight of coconut oil, and 10 to 30 parts by weight of lecithin are mixed, and then stirred under heating at 70 to 80° C. to prepare vegetable fatty acids. It is a step.

The soybean oil (soybean oil) is a (semi) dry oil obtained by extracting a solvent from the soybean seed, also called soybean oil. The soybean oil content of the seed is 13-26%, the iodine value is mostly 125-135, and the main component fatty acid is linoleic acid. 50%, oleic acid is about 25-30%, contains linolenic acid 2-10%, palmitic acid 2-10%, and stearic acid 2-5%. Fats and oils containing fresh linoleic acid are effective for prevention and treatment in plasma, but fats and fats containing a large amount of polyunsaturated fatty acids are easily oxidized. As a result, the resulting lipid peroxide is toxic, so it avoids air, light, and heat, and prevents automatic oxidation. Should be suppressed. On the other hand, the isopolone contained in soybean oil provides moisture and nutrients to the skin.

This is a step of preparing a colloidal mixture by mixing 10 to 20 parts by weight of a surfactant with fatty acids, 5 to 15 parts by weight of an organic solvent, and 5 to 15 parts by weight of a natural emulsifier, and then stirring at a high speed at 3,000 to 4,500 rpm.

The surfactant is to promote the condensation reaction with fatty acids, at least one selected from ethylene oxide, isooctylphenoxy polyoxyethoxyethanol, p-tert-oxyphenoxy polyethoxyethanol, and polyhydric alcohol It can be illustrated, but is not limited thereto.

The organic solvent is to secure a smooth flow and flowability of the composition by preventing solidification of soybean oil and coconut oil, and at least one of butylene glycol, polyethylene glycol system, propylene glycol, isopropyl alcohol, and stearyl alcohol It may be illustrated that is selected, but is not limited thereto.

The natural emulsifier serves to emulsify fatty acids and surfactants, and it is preferable to select at least one selected from Gati gum, Arabian gum, Xanthan gum, and Guar gum, which are natural materials with little irritation and excellent emulsification performance. .

In step S3 of the present invention, 5-20 parts by weight of plant components comprising green tea extract, ginkgo biloba extract, and aloe vera extract, and 1-5 parts by weight of royal jelly are added to the mixture of step S2 and colloidal by stirring at a high speed of at least 5,000 to 7,000 rpm. This is the step of ultra- atomizing the particles.

Since the green tea extract contains catechin as an antioxidant, it helps to prevent skin aging and wrinkles.

The ginkgo biloba extract contains ginkgorides A, B, C, ginol, and prabonol. It removes harmful oxygen and prevents skin aging with antioxidant effect, protects cell membranes, gives skin shine and improves dry skin In addition, the prevention of fine wrinkles and the pore-reducing extract may be extracted through a process of filtering or concentration or drying to remove the solvent.

The aloe vera extract can be obtained by squeezing aloe vera, and the aloesin contained therein has the same whitening effect as vitamin C, suppressing the action of tyrosinase to produce melanin pigment, and mucin, a sticky ingredient. It moisturizes dry skin, and the amino acids and sugar proteins contained in aloe confer activity on the skin, and contains polysaccharides such as glucomannans and pectic acid and many other organic and inorganic compounds.

The royal jelly contains nutrients such as vitamin B, attylcholine, alaminobutyric acid, pantothenic acid, vitamin E, and bichotin, and it has the effect of supplying nutrients to the skin and making the dry skin fresh and moist.

Meanwhile, in the present invention, high-speed and ultra-high-speed agitation is performed in the process of preparing the composition, and may further include steps S1-1 and S2-1 to further decompose colloidal particles.

More specifically, it may further include a step S1-1 of self-aging the vegetable fatty acids subjected to the step S1 and a step S2-1 of aging the mixture subjected to the step S2. In step S1-1, 100 parts by weight of soybean oil, 30 parts by weight of coconut oil, and 15 parts by weight of lecithin are mixed in a maturing tank with a plurality of magnets attached to the bottom or inner wall, and then mixed at a temperature of 70°C. (Step S1) To this mixture, 20 parts by weight of isooctylphenoxy polyoxyethoxyethanol, 15 parts by weight of isopropyl alcohol, and 5 parts by weight of Gati gum were mixed, followed by high speed stirring at 3,000 rpm to obtain a colloidal mixture. (Step S2) Put 10 parts by weight of plant components consisting of green tea extract, ginkgo biloba extract, and aloe vera extract, and 1 part by weight of royal jelly, and ultra-high-speed agitation at 7,000 rpm to colloidal particles into ultra-fine particles (S3 step). The natural cosmetics of the present invention are prepared.
