Description

Manufacturing method of suspension cologne cosmetics

The present invention relates to a method for producing a suspension cologne cosmetics directly used in the human body, and more particularly, using no alcohol or a small amount of alcohol, perfume, oil, moisturizer or natural animal and plant extracts, etc. By adding various active ingredients that can be used in the cosmetics of the present invention relates to a method of producing a cosmetic cosmetics that can not only give a odor to the human body but also increase the persistence of the odor and at the same time impart a moisturizing and supple effect to the skin.

In general, cologne cosmetics are used in the body or clothes to maintain a long lasting fragrance for a long time, especially in Korea as a cosmetic directly used in the body is widely sold under the name 'shower cologne'. In the case of such a shower cologne, the alcohol is usually used by more than 50% by weight, and most of the transparent products are dissolved in alcohol or solubilized using a suitable surfactant. Cologne cosmetics of this type not only provide a odor to the body, but also give a cool texture by evaporation of alcohol after use. However, since the skin is dried by evaporation of alcohol and has a problem of causing skin irritation considerably, when using cologne cosmetics, bath oil or body lotion may be used separately.

In order to minimize the irritation to the skin and to give the skin a supple effect in the protection of the skin, various formulations of shower cologne containing various oily ingredients were introduced. For example, in particular, 55189 (92.10.7) contains inorganic powder. It has been proposed to use the oily ingredients in the form of droplets to disperse in an aqueous alcohol solution and shake gently. However, in the case of a usable product, the type and content of oil components that can be used are limited, and if the solubilization is not sufficient, there is a problem that separation of oil components occurs in the upper layer or the lower portion. In addition, in the case of oil quadrature products, there are limitations on the oily component which has the appearance characteristics, but also has excellent quadrature forming ability, and there is a limit to the use of water-soluble additives such as moisturizers because no surfactant is used. .

Therefore, the inventors of the present invention, while seeking various solutions to solve the drawbacks of the alcohol-containing cologne cosmetics based on the solubilization phenomenon, in the case of taking the suspension form as an oil-in-water emulsion, A new type of suspended cologne cosmetics has been studied with the idea that the ingredients can be easily added and the range of selectable oily ingredients can be broadened. In other words, in the case of suspended cologne cosmetics can be added to the oil in addition to the fragrance to increase the softening effect on the skin, and can also effectively add ingredients such as water-soluble additives such as moisturizers and animal and vegetable extracts. However, emulsions are thermodynamically unstable compared to solubilized products, and in the case of general emulsification, they have a certain viscosity to stabilize the formulation. Such viscous emulsified products satisfy the neat use of Kolon cosmetics. I can't give it. In addition, it is very difficult to obtain a stable formulation because the emulsified state can be destroyed by the alcohol when the alcohol is added to increase the fresh feeling.

Therefore, the present inventors have little viscosity, and during the study to prepare a suspension cologne cosmetics containing various components having a moisturizing effect, adding oil-soluble components dissolved in alcohol and using an aqueous surfactant solution The present invention has been completed by discovering that it is possible to obtain a very stable formulation in suspension form, and furthermore, to produce an alcohol-free, branched cologne cosmetic containing no alcohol. That is, the water-soluble component can be incorporated into the water phase, and the fragrance and various oil-soluble components can be stably dispersed into very fine particles of 0.5 to 1.0 mu m or less using a surfactant and an alcohol. In addition, in the case of using a small amount of alcohol or using fragrances and oils that are not soluble in alcohol, the fragrances and oils are gradually added to a polyhydric alcohol solution such as propylene glycol, glycerin, and butylene glycol to form a gel and then aqueous solution or Dilution with an aqueous alcohol solution gives a very stable suspended product in the form of a fine, uniform O / W.

As a result, the fine emulsified particles thus formed are able to maintain a very stable state despite almost no viscosity, which is dispersed through Brownian motion without following Stock's rule related to sedimentation and flotation of the particles. Because it is. That is, if the particles are dispersed in fine particles having a size of about 1 μm or less, preferably 0.5 μm or less, and an appropriate surfactant is selected to prevent their coalescence, the particles may be caused by Brownian motion rather than the speed at which the particles float and settle. Zig-zag motion can be increased to stabilize the emulsion.

In the case of the suspended cologne cosmetics, the moisturizing power, safety, and scent persistence of the skin after use are considerably increased compared to the existing cologne cosmetics, and especially, in the case of the shower cologne, an oil-based component and a moisturizing agent that are solubilized by alcohol well Effectively adding ingredients such as animal and vegetable extracts can increase the flexibility and moisturizing of the skin.

EMBODIMENT OF THE INVENTION Hereinafter, the Jeju method of the suspension cologne cosmetics of this invention is demonstrated in detail.

The present invention can be divided into two cases according to the content of the alcohol and the content of the oil used. That is, it contains a case where it does not contain alcohol enough to dissolve the oil and fragrance to be used sufficiently.

First, when the alcohol content is 10-45% and contains enough alcohol to dissolve the oil and perfume to be used, the oil and fragrance are dissolved in alcohol, and then a surfactant is added thereto, followed by an aqueous phase. It is a method of finely dispersing perfume and oil particles by energy dispersed in alcohol by dispersing in water.

At this time, there is no particular limitation on the ratio of the alcohol phase and the aqueous phase, but usually 10 to 45% by weight of the alcohol phase is used.

Polyhydric alcohols, such as propylene glycol, butylene glycol, glycerin, and D-sorbitol as a component to be incorporated into an aqueous phase; Moisturizing components such as hyaluronic acid and chitosan derivatives; Vegetable extracts such as green tea extract, licorice extract, rosemary extract, matricaria extract and the like and animal extracts such as placenta extract, timer peptide and the like; There are vitamins such as panthenol and ascorbic acid. In addition, as a water-soluble additive used for cosmetics, antioxidant, a sunscreen, a chelating agent, a pigment | dye, etc. can also be used. Thickeners may also be used, in which case they may be used in small amounts to improve the experience, not just to stabilize the product.

In the alcohol phase, an oily component soluble in alcohol can be dissolved until it reaches a saturation state, but it is appropriate to use about 0.5 to 50% by weight with respect to the alcohol. Such oily components include silicone oils of cyclomethicone and phenyldimethicone; Triglycerides such as caprylic capric triglyceride, macadamia nut oil, and jojoba oil; Ester oils such as cetyloctanoate, isopropyl myristate and octyldodecyl myristate; Vitamins such as tocopherol and its derivatives; There are higher fatty acids and higher fatty alcohols, and it is necessary to use them in combination in consideration of the feeling of use or dispersion state of the emulsified particles.

As the surfactant, any hydrophilic surfactant that can be used in cosmetics may be used. Preferably, a nonionic surfactant having a polyoxyethylene group is suitable. Among these nonionic surfactants, polyoxyethylene hydrogenated castor oil , Polyoxyethylene higher fatty acid ester or polyoxyethylene higher fatty acid ether. It is advantageous to use a surfactant having a relatively high molecular weight and volume of a lipophilic group such as polyoxyethylene cholesteryl ether polyoxyethylene tocopheryl ether and the like to prevent aggregation of the dispersed oil to prepare a stable suspension.

In addition, since the stability of the suspended cologne cosmetics has a very close relationship with the particle size of the dispersed oily component, it should be formed as small as possible so that no aggregation occurs. Dispersing the oily material to be dispersed in the particles of 1㎛ or less so that the Brownian motion is enough to break the particles by applying a strong pressure, a method using an ultrasonic wave or a method using a membrane. However, these methods disperse particles with completely mechanical force and are not desirable in terms of energy. However, as in the manufacturing method of the present invention, when the alcohol phase is gradually added to the aqueous phase while slowly stirring using a stirrer, uniform and fine particles are applied without applying a strong mechanical force to the energy generated as the alcohol phase diffuses into the aqueous phase. Can be formed. However, if bubbles are generated during stirring, the resulting oily particles may become unstable, so it is also important to prevent bubbles from being produced during manufacture.

Secondly, if it does not contain alcohol, or if the fragrance or oil to be used contains less than 10% of the alcohol to the extent that it is not sufficiently soluble in alcohol, the first step is to prepare a viscous suspended cologne cosmetic without water or interface. An active agent and a polyhydric alcohol may be mixed, and a fragrance and oil may be gradually added to form a gel, and then fine particles may be formed by diluting it with an aqueous solution or an aqueous alcohol solution to prepare a stable suspended cologne cosmetic.

In this case, a surfactant having high hydrophilicity may be used alone, or a surfactant similar to the HLB (Hydrophile Lipophile Balance) required for the oil used may be selected to prevent coalescence of particles. It may be used, or a suitable combination of a hydrophilic surfactant and a lipophilic surfactant may be adjusted to suit the HLB required for the oil. For example, in the case of liquid paraffin, the surfactant having a HLB value of 8.2 to 15.3 can be selected to finely disperse the emulsified particles, and the emulsion thus obtained is not viscous because the extremely fine particles move in a brown motion. Despite this, it can maintain a very stable state.

As the polyhydric alcohol, dihydric alcohols such as propylene glycol, butylene glycol, 1,4-butanediol, and 1,5-pentanediol are suitable, and they are used in cosmetics such as glycerin, ethylene glycol, polyethylene glycol, and D-sorbitol. All polyhydric alcohols can be mixed. It is preferable to use 0.5-30 weight% of polyhydric alcohols.

In addition, as an additive other than the fragrance which can be added to the gel-like composition, various moisturizing ingredients which can be contained in the cologne cosmetics sufficiently containing the above-mentioned alcohol, water-soluble additives such as animal and plant extracts, and a small amount of alcohol And oily components likewise, and in addition, hydrocarbon oils such as liquid paraffin, squalane and the like, which are insoluble in alcohol, and mixtures thereof can be used. The oily component of these components is added directly to the gel phase, and the water-soluble additive and alcohol are dissolved in purified water to form an aqueous solution or an aqueous alcohol solution to dilute the gel phase. Although the content of these components is not specifically limited, 0.5-50 weight% is suitable.

Suspended cologne cosmetics produced as described above are stable cologne cosmetics containing no alcohol or containing only a small amount of alcohol, and can provide an effect that was never conceived in conventional cologne cosmetics in terms of skin moisturizing and flexibility. In addition, the use of fragrances and various oily ingredients can significantly increase the duration of fragrances and provide long-lasting effects of cologne cosmetics.

Hereinafter, the production method of the suspension cologne cosmetics of the present invention will be described in detail with reference to Examples.
