Pet cleaning shampoo composition containing fragrance capsule {Pet care shampoo of fragrance capsule}

The present invention relates to a pet shampoo composition for cleaning a pet's hair and skin, the pet shampoo composition comprising a microcapsule containing fragrance in the core-shell structure It is about.

The shampoo composition of the present invention is characterized in that the liquid is stabilized through the flavor capsule and the fragrance is slowly and continuously smelled out of the capsule in the air.

In the present invention, the pet (愛 동물 動物) refers to an animal that is raised for human satisfaction by listening to sounds, admiring a figure, or enjoying a cute gesture, and the present invention has been widely breeded by humans for a long time. The present invention has been completed for dogs or cats that require hair washing.

The cleaning shampoo of the present invention refers to a product whose main purpose is to keep the skin and hair clean by removing contamination attached to the skin and hair of the pet. In the present invention, the shampoo typically improves the texture and appearance of the hair and skin after the process of cleaning and cleaning in addition to the purpose of maintaining cleanliness, and provides additional functions such as styling and hair protection to provide product value. It is raising.

Accordingly, the pet washing shampoo of the present invention refers to a shampoo product which includes the provision of the above-mentioned additional functions in pets and which is intended to maintain cleanliness by washing, and which is a shampoo unlike a normal human washing shampoo. The shampoo for pet washing is added to the shampoo for human body by the difference of the basic cleaning function due to the difference in the type or content of the surfactant in the shampoo composition. In terms of function, the characteristics of shampoos are distinguished, and products are being developed. From this, it is a general trend to increase the satisfaction of shampoo users' products. As a result of the need for the above-mentioned difference in the above-mentioned functions, the shampoo for pets and the human body is distinguished from the characteristics of the skin and hair of the subject, and the pet shampoo can directly feel the feeling of the skin during and after the shampooing process. It is distinguished by the fact that a person judges the good or bad of the product through indirect observation and feeling of the object, and in general, the frequency of use is lower than that of the human body in terms of the frequency of use, so pet shampoo Is different from shampoos for human cleansing. The self-investigation has shown that domestic shampoo users typically shampoo their hair within 1 to 3 days. Most dogs appear to be shampooed within 5 to 15 days. If the frequency of use of the shampoo is lower than for humans. Therefore, it is preferable that the pet shampoo for pet washing of the present invention maintains the condition of the skin and hair of the pet after washing for at least one week.

In the present invention, when the pet is washed, the smell of the pet is removed by washing. In particular, the state of removing the smell needs to be maintained for a long time after washing, more preferably for a week. Both humans and pets may produce odors due to skin secretions and decay of pollution, which may cause unpleasant feelings to humans.However, pets are distinguished from human smells and are sensitive to humans. You can get more unpleasant feelings. Therefore, the conventional pet cleaning shampoo uses a stronger scent than the human shampoo so that a person can not feel the peculiar smell of the pet and smell a certain intensity for a longer time, causing unpleasant occurrence in the pet. We try to reduce the feeling, but not only the fragrance is too strong at the beginning of the cleaning process and after washing, but most of the fragrance is smelled after 2 days after shampooing. After 3 days, it does not improve, and in this state, there is a disadvantage in that it is not possible to expect a long-term effect of not recognizing the unpleasantness of pets due to the smell of the fragrance component or to relieve human emotions by the smell of smell. .

Accordingly, the present invention provides a shampoo composition containing a flavor capsule to maintain the state of the dispersion as a composition in the liquid phase through the flavor capsule while the capsule is to the hair by the surface of the capsule modified with silver (silver) during the shampoo process It adsorbs very well, and after shampooing, the fragrance ingredient gradually comes out into the air outside the capsule in a dry state in the air, and continuously smells, so that a certain intensity of fragrance is continuously scented from the pet's hair and petting the pet. The purpose of the present invention is to provide a shampoo composition for pets that makes the part of the capsule burst by external force so that the fragrance of the fragrance from the burst capsule is further promoted.

In the fragrance capsule of the present invention, the capsule refers to a core-shell structure having a particle size of less than 1000 μm, and may be represented by a spherical core of the fragrance component and a shell structure surrounding the outside thereof. have. The fragrance component is not dissolved in water and is useful, and the shell component is formed by a polymer which is water soluble and incompatible with the fragrance so as not to be dissolved by the fragrance component. Such flavor capsules can be understood and made by one of ordinary skill in the art. One traditional and common method of preparing flavor capsules is the coacervation method, which is used to produce arabic gum and carboxy methyl cellulose at high temperatures of 40 to 80 degrees Celsius. , Emulsion droplets are formed by a homomixer in an anionic polymer solution such as sodium alginate, and then cationic gelatin or albumin polymer is added and the pH is adjusted to 4 to 4.5 to obtain liquid coacervate. ), Gelled by cooling to 5 to 15 degrees Celsius, and a core-shell structure through a curing process that hardens the surface through crosslinking of the cationic polymer shell by adding a crosslinking agent such as glutaaldehyde. There is a method to form and to control the type of the cationic polymer and the size of the applied capsule It was a major factor controlling it. The present invention has been confirmed that the characteristics exhibited by the capsules are different from the conventional ones due to the modification of the surface properties of the core-shell structure during the curing process while applying the conventional techniques. The result of increasing the adhesion of the fragrance capsule to the hair was obtained. In the case of the shampoo containing the fragrance capsule of the present invention, since the surface of the shell is modified to increase the adherence to the hair, which is the final substrate during the washing process, the capsule containing the fragrance ingredient is surfactant and water during the washing process. It provides a fragrance capsule that can be attached more effectively to the hair without being washed away with the fragrance. In the present invention, the nanoscale silver colloidal particles were attached to the capsule surface during the curing process before the cationic polymer completely completed the curing. In the present invention, the increase in the adhesion to the hair by the silver capsule is a shell in which the silver particles corresponding to one polymer capsule are nano-sized and very small in number, and the silver particles adhere to the capsule surface. It is natural that the surface properties of the film are modified, and above all, the surface roughness increases the frictional force of the capsule against the hair protein than the unmodified polymer itself, which prevents it from being washed with water during the cleaning process. It is believed that the adhesiveness is increased and it can be attached to the hair well.

Silver (Ag) used outside the capsule of the flavor capsule in the present invention is an element belonging to Group 11 of the chemical periodic table, and is a well-known metal element from the past, a kind of precious metal such as gold, iridium, palladium, platinum, and the like. Nano scale silver colloid described in the present invention has a method of manufacturing by the method of electrical, chemical, grinding. In addition, the colloid applied in the present invention is a colloid (colloid) having a size of less than 100 nanometers (nanometer, nm) suppresses the propagation of more than 650 kinds of pathogens, bacteria, bacteria, fungi, etc., and has a bactericidal effect. In addition, the color of these colloids is generally colorless or golden yellow, and the larger the silver particles, the darker the color and the more precipitates are produced. In addition, if the particles are too large, the sterilization effect is reduced, so that the sterilization effect can be strongly represented by the silver colloid particles (silver colloid particles), that is, the specific surface area of the particles that can act on the object, that is, the maximum surface area of particles per weight 2 to 20 It is preferred to be prepared at the nanometer level.

When the silver colloidal particles are applied to the polymer particles during the curing process, the silver colloidal particles may be fixed, the surface properties may be changed roughly, and sterilization characteristics may be exhibited.

The content of the silver component used in the present invention is preferably 50 to 500 ppm relative to the total weight of the fragrance-containing microcapsules.

If the content of silver is 50 ppm or less, the adhesion to the hair is lowered. If it is 500 ppm or more, the adhesion is not increased by increasing the concentration.

The properties of the shampoos other than the flavor capsules for completing this invention are similar in composition as they do not differ significantly from conventional shampoos. Basic properties of shampoos conventional in the present invention are as follows. First, it should have proper cleaning. Contamination should be removed sufficiently, but proper cleansing power is needed to remove the sebum needed for skin and hair. Creamy, long lasting foam should occur and the hair should be protected from tribological damage. In addition, natural hair shine and moderate flexibility should be given to the hair after trituration, and stability to skin, hair and eyes should be high. Conventional shampoos in terms of add-ons include the following types of shampoos. Oil shampoo or cream shampoo that contains oil to improve the feeling after cleaning, Conditioning shampoo to prevent hair damage in tricycle, Dandruff shampoo to prevent dandruff and itching, Low irritation to skin and hair than usual Shampoo, rinse combined shampoo that gives a rinse function, such as friction reduction of the surface of the hair, antistatic, hair protection, and the like, can be used in combination of some of these functions.

The shampoo composition of the present invention may be added to the bubble detergent and other additives. As the bubble cleaner, anionic surfactants, amphoteric surfactants and nonionic surfactants are used and solubilized. Anionic surfactants are used as the main bubble cleaners for shampoos. They mainly use good foaming and inexpensive alkyl sulfate ester salts (AS) and low-temperature transparent, low-irritancy polyoxyethylene alkyl ether sulfate ester salts (AES). Highly safe acylmethyltaurine salt, mild acyl glutamate with mild irritation to the skin or eyes is used, in which salts are sodium salts, ammonium salts and trimethanolamine Salts and the like. Examples of commercially used sodium salts include sodium lauryl sulfate as the alkyl sulfate ester salt and polyoxyethylene lauryl ether sulfate as the polyoxyethylene alkyl ether sulfate salt. .

Amphoteric surfactants are used in combination with anionic surfactants for ancillary purposes such as safety enhancement, thickening, alkyl betaine, alkylamide betaine, and imdazolium betaine. Betaine and glycinate such as betaine are applied, and mainly cocoamido propyl betaine, cocoamphocarboxy glycinate, etc. are frequently used. Is inferior to anionic surfactants but is hypoallergenic.

Nonionic surfactant is a bubble cleaning aid that plays an auxiliary role in improving bubble stability, thickening and low temperature stability of anionic surfactant, and mainly applies monoethanolamide and diethanolamide. Seed diethanol amide (cocofatty acid diethanol amide) and lauric acid diethanol amide are frequently used.

Other additives include higher fatty acids such as lanolin derivatives, liquid paraffin, isopropyl palmitate or isopropyl myristate, higher alcohols such as higher alcohols, ester oils and silicone oils, or acrylamide and dimethyl ammonium. Polyquaternium-7, a quaternary ammonium polymerized by chloride, or polyquaternium-10, a quaternary ammonium polymerized with hydroxyethylcellulose and epoxide substituted with trimethylammonium. Cationic polymer conditioning agents are formulated, and anionic such as moisturizers such as glycerin, carbopol 1342, which is an acrylate copolymer, or carbopol aqua SF-1, which is a copolymer of acrylate and alkyl acrylate. Viscosity control and dispersion stabilizers by polymers, metal ion sequestrants, UV absorbers, preservatives, Stabilizers, such as a pH adjuster, an emulsion, a pigment | dye, a fragrance | flavor, etc. are added.

In contrast, the rinse function adsorbs cationic surfactants such as alkylmethylammonium or dialkylmethylammonium and oils such as hydrocarbons, higher alcohols, ester oils and silicone oils to smooth the hair. Moisturizing agents such as glycerin, propylene glycol, 1.3 butylene glycol, and polyethylene glycol are mixed together to moisturize and moisturize. The rinse combined shampoo advances conventional conditioning shampoos to advance the basic conditioning shampoo. An anionic or amphoteric surfactant is applied as a rinsing agent, and a cationic surfactant such as Cethyl trimethyl ammonium chloride, Dimethicone copolyol phthalate, di Mech Copolyol phosphate (Dimethicone copolyol phosphate) and is used in combination with such silicone derivatives, oils and other hydrocarbon-based and so on. In general, cationic surfactants and anionic surfactants form insoluble complexes in water and are precipitated. Therefore, in addition to the terminal hydrophilic groups, having a separate hydrophilic group in the molecule forms a water-soluble complex, and thus can be combined with an amphoteric surfactant. have. Such rinse shampoos do not depart from the scope of the present invention.

Hereinafter, the present invention will be described in detail by way of Examples and Comparative Examples.

Although the shampoo composition of the present invention uses the conditioning shampoo as an example, the formulation of the conditioning shampoo does not limit the content of the present invention. Purified water is added to a dissolution tank with a heating facility at room temperature, and then dissolved by adding a cationic surfactant, polyquaternium-10. The solution is sufficiently stirred and dissolved, and then heated and stirred to 60 degrees, sodium lauryl sulfate as an anionic surfactant. And sodium lauryl ether sulfate, an amphoteric surfactant, cocoamphocarboxy glycinate, and a cationic surfactant, Cethyl trimethyl ammonium chloride, and a nonionic surfactant. Cocofatty acid diethanol amide and isopropyl palmitate oil, NaCl, Dimethicone copolyol phthalate, a silicone derivative, EDTA is added to the chelating agent to disperse and dissolve. After slowly cooling to 50 degrees, the mixture is thoroughly stirred with Carbopol 1342 as a dispersion stabilizer, Lquid pearl as an opacifying agent, triethanolamine (TEA) as a neutralizing agent of Carbopol, a flavor capsule, and a preservative.

As a result of the determination, in the case of Comparative Example 3 compared to the Examples and Comparative Examples, the intensity of incense was higher, but the satisfaction was rather low, and it was judged to give an impression that it was strong. Satisfaction declined sharply in the first phase, which shows that the application of aroma capsules can provide an adequate scent intensity.

The scent intensity tends to increase overall when scenting dog's hair several times than when it smells naturally, and when scent capsules are provided, stroking by hand even if the scent intensity drops after several days This resulted in an increase in the intensity of the scent, which is believed to contribute to the increase of satisfaction.

In addition, when the overall trend from day 1 to day 16, the fragrance composition concentration in the shampoo composition in the shampoo composition is 0.5% as in Example 1, the fragrance intensity when the fragrance composition concentration in the shampoo composition is 1.0% is similar It can be seen that this increased the adhesion strength of the capsule by the nano-silver capsules increased the strength of the flavor. It was found that the same or more effects can be obtained even if the flavor concentration of the capsule is reduced by 50%, indicating the superiority of the present invention.

According to the present invention, the shampoo composition containing the fragrance capsules surface-modified with silver is more adsorbed to the hair during the shampooing process, so that the fragrance component is continuously scented into the air outside the capsules after the shampooing, and the external force when petting the pet By allowing a portion of the capsule to burst by the fragrance of the fragrance from the capsule is further promoted to provide a pet shampoo composition to please the person.
