Description

Powder sunscreen cosmetic composition

The present invention has a high UV protection effect and does not appear sticky or whitening phenomenon is excellent in use, UV protection cosmetic composition also has the ability to modify the cosmetic function, such as being able to continuously apply even after the color makeup that was not possible in the existing UV protection cosmetics It is about.

The present invention also relates to a sunscreen cosmetic composition that takes advantage of the synergy between organic sunscreens (or organic and inorganic sunscreens) and sunscreen potentiators.

Recently, the ozone layer is destroyed due to environmental pollution, and the ultraviolet exposure is intensified. These ultraviolet rays act as a major cause of erythema, swelling, freckles, and skin cancer on the skin. Accordingly, the development of a product that protects the skin from ultraviolet rays has recently been required. In particular, as life becomes rich, there is an increasing demand for protecting skin from ultraviolet rays during leisure activities such as skiing, golfing, and sea bathing, as well as the desire to protect the skin from ultraviolet rays in everyday life. Numerous studies have been conducted to satisfy the demands of these consumers.

In general, ultraviolet light is divided into three areas according to the wavelength. That is, the wavelength of 200-290 nm is classified as ultraviolet C (UV-C), the wavelength of 290-320 nm is ultraviolet B (UV-B), and the wavelength of 320-400 nm is classified as ultraviolet A (UV-A). . Among them, UV-C passes through the ozone layer and disappears without reaching the ground surface. UV-B penetrates the skin's epidermis, causing erythema, freckles and edema. UV-A is known to induce skin aging and skin irritation such as penetrating the dermis of the skin to promote skin cancer, wrinkles and melanin formation.

The public's interest in sunscreen products has increased as the risk of sun exposure has become known. Accordingly, products with various sun protection factors (SPF) and protection grade of UVA (PA) have been released.

Most sunscreen formulations are classified as emulsion type, water-in-oil (W / O) and oil-in-water (O / W). Among them, the oil-in-water type product has a good feeling of use, but the water resistance is inferior, so there is a problem in that the sunscreen effect is reduced by sweat or water. On the other hand, water-in-oil type products are superior in water resistance but less usability than oil-in-water type products.

Today, consumers have to use a large amount of sunscreen ingredients to achieve the high levels of sunscreen protection they want. Sunscreens are essentially inorganic sunscreens (eg titanium dioxide, zinc oxide, or zirconium oxide) and organic sunscreens (eg octylmethoxycinnamate, octylsalicylate, octocrylene, butylmethoxydi Benzoylmethane, oxybenzone, octyltriazone, menthylanthranilate, or 3,4-methylbenzylidene camphor). Chemical sunscreens, also known as organic sunscreens, defend against the reaction of ultraviolet light to the skin by absorbing the wavelength range of the ultraviolet region. Physical blockers, also known as inorganic sunscreens, protect against the reaction of UV light to the skin by scattering light in the ultraviolet region.

Excessive chemical sunscreen can cause skin irritation and various troubles, so most countries have a formula limit. In addition, most organic sunscreens are liquids with a fairly high viscosity which leads to stickiness and must be used with oils of high viscosity that can be solvents of organic sunscreens. Therefore, existing organic sunscreen containing products have been prepared in the form of creams or lotions, and the stickiness is difficult to completely eliminate. Therefore, the feeling of sunscreen cosmetics is significantly reduced.

On the other hand, inorganic sunscreens such as titanium dioxide and zinc oxide have been in the spotlight recently because they are relatively safe for the skin. However, due to the high refractive index of the material itself, the skin appears cloudy, causing a hazy appearance.

Recently, a sunscreen product manufactured in solid form using wax has been released. This product uses puff to spread the composition on your face. These products are very useful because they do not leave hands sticky when used. However, there is a limit to essentially removing the stickiness of the product.

Consumers also want to apply sunscreen often during their daily lives, especially after makeup. However, existing lotion or creamy products or waxy solid products are difficult to apply because of their stickiness. In particular, when applying over makeup makeup, it is almost impossible to apply it because of the fatal disadvantage that the makeup may collapse.

Therefore, the technical problem to be achieved by the present invention has a very high level of UV protection ability, but almost no stickiness or opacity does not appear, the use is excellent, it can be continuously added even after the color cosmetics that was impossible in the existing UV-blocking cosmetics, etc. It is to provide a powdery sunscreen cosmetic composition capable of correcting cosmetic function.

As described above, in order to manufacture a powdery sunscreen having high sunscreen ability, when a large amount of inorganic sunscreen is used, a cloudy appearance occurs in the skin, and organic sunscreen is used to lower the content of the inorganic sunscreen. Excessive use will not only form a powder, but will also cause stickiness in use. It is an object of the present invention to provide a powdery sunscreen composition having high sunscreen ability with little incidence of stickiness and cloudiness.

In order to achieve the above technical problem, the present invention provides a powder-like, more preferably compressed powder-like sunscreen cosmetics having the following characteristics.

The sunscreen cosmetic according to the present invention is prepared in a powder form by spraying and mixing 3-30% by weight of the oil binder part (B) to 70-97% by weight of the powder part (A) relative to the total weight of the cosmetic, and has an infiltration hardness of 5- 65 (JIS K 6301, Asker JAL Type), and the UV protection index (SPF) is characterized in that 30-80.

Preferably, the powder type sunscreen composition further comprises a compression molding or a baked molding process by, for example, tableting or the like after the spraying and mixing, and the penetration hardness is 5-65 (JIS K 6301, Asker JAL Type) can be prepared in powder form. More preferably, the cosmetic preparation according to the present invention is prepared through a process of sieving and / or aging before the tableting or compression process.

According to the present invention, the process of mixing the oil binder portion (B) to the powder portion (A) may be performed by mixing at high speed in a mixer such as a Henschel mixer so that the injected oil portion may be uniformly mixed. . However, the method of mixing the powder portion A and the oil binder portion need not be limited to the Henschel mixer, and the powder type according to the present invention may be used as long as it is a device capable of uniformly mixing the powder portion A and the sprayed oil binder portion. It can be used to prepare sunscreen compositions.

On the other hand, since the mixture of the powder portion (A) and the oil binder portion (B) uniformly mixed may occur between the agglomeration of particles, it may be further subjected to a crushing process to solve this.

In addition, since the mixture of the powder portion A and the oil binder portion B uniformly mixed may include foreign matter or agglomerated particles of the mixture, the process of filtering the mixture before performing compression molding or baked molding. Can be performed further. Filtration can be carried out using a mesh of a certain size, for example, a size that allows the mixture particles to pass but not foreign matter or aggregated particles.

Compression molding or bake molding of a mixture of the uniformly mixed powder portion A and the oil binder portion B directly produces non-uniform pores due to the air present between the mixture particles. (crack) may occur. Therefore, in order to solve this problem, it may be desirable to perform a aging process to remove the uneven pores by leaving the mixture for a predetermined time or more before compression molding or baked molding.

According to the present invention, the conditions for performing compression molding or baked molding such as tableting of the mixture of the powder part A and the oil binder part B (for example, the tableting pressure or the baked molding temperature) are determined according to the hardness condition. It may vary. Those skilled in the art can easily modify the molding conditions according to the desired hardness. For example, the pressure during compression molding may be carried out in the range of 15-100 kg / cm ² , and the baked molding may be performed at a temperature of 40-120 ° C.

The sunscreen on the powder according to the invention preferably has a UV A protection grade (PA) of double plus (PA ++) to triple plus (PA +++).

The cosmetic according to the present invention may include the powder portion (A) 70 to 97% by weight relative to the total weight of the cosmetic. That is, it is preferable that 70 wt% or more is included to maintain the powdery formulation without stickiness. In addition, it is preferable to be included in 97% by weight or less in order to prevent moldability and adhesion, that is, processing and powder fall. That is, when the powder portion is used in excess of 97% by weight, problems such as dusting may occur because the bond between the powder particles by the oil portion is weakened.

As used herein, unless otherwise indicated, the term "powder" means a collection of solid materials having a particle size of 1 mm or less. Powders usable in the present invention include extender pigments, coloring pigments, inorganic sunscreens and powdery organic sunscreens commonly used in the cosmetic field.

The powder part (A) included in the cosmetic according to the present invention contains the coloring pigment in an amount of 0 to 0.5 parts by weight based on 100 parts by weight of the total powder part. Even if the pigment is not used or is used in the powder part, it is used in a very small amount, so that the color of the color make-up is not affected when the color make-up is applied after applying the sunscreen cosmetics, and the powdery ultraviolet light according to the present invention after the makeup is completed. It is desirable not to change the color of the tint when applying the barrier. The coloring pigments are all materials capable of expressing color in color cosmetics, and include, for example, organic synthetic pigments, natural pigments, pearlescent pigments, and the like.

According to the present invention, the extender pigments include inorganic pigments including mica, talc, kaolin, alumina, barium silicate, zeolite, white mica, synthetic mica, silica, magnesium carbonate, barium sulfate, iron titanate and titanium oxide coated mica; It is preferable to use one or more selected from the group consisting of polystyrene powder, polymethyl methacrylate powder, polyethylene powder, and organic pigments including nylon powder. However, not only those listed above, but also extender pigments commonly known in the art, for example, extender pigments described in "new cosmetics, Kwon Kyung-ok translation, book publishing technology, publication date 30 October 1997" It can be used as an extender pigment described in.

In addition, the extender pigment is preferably used to be hydrophobized. Specifically, it can be used by treating the surface of the powder pigment with high viscosity silicone, alkyl hydrogen polysiloxane, cationic surfactant, anionic surfactant, nonionic surfactant or wax.

The cosmetic according to the present invention may include an inorganic sunscreen. The inorganic sunscreen is preferably selected from the group consisting of titanium dioxide having an average particle size of 0.01 to 100 nm, zinc oxide having an average particle size of 0.01 to 300 nm, and cerium oxide having an average particle size of 1 to 300 nm. Do. However, the present invention is not limited thereto, and any substance approved for use by the KFDA may be used as the inorganic sunscreen of the present invention.

In addition, the cosmetic composition according to the present invention comprises 3 to 30% by weight, preferably 5 to 12% by weight of the oil binder portion (B) relative to the total weight of the cosmetic. That is, the oily component is preferably included 3% by weight, preferably 5% by weight or more in order to provide formulation stability, that is, the bonding force between the powder particles forming the powder portion (B). In addition, in order to make the powder into a usable and non-sticky, it is preferably contained in 30% by weight, preferably 12% by weight or less.

'Oil', as defined herein, unless otherwise indicated means a hydrophobic liquid substance that has viscosity at room temperature. These oils provide a bonding force between the powder particles and at the same time provide a smooth feeling when applied to the skin to provide a uniform application to the face. Oils according to the present invention include synthetic oils, vegetable oils, animal oils and mineral oils commonly used in cosmetics, in addition to oil-based organic sunscreens.

The component of the oil binder portion (B) in the cosmetic according to the present invention is not particularly limited in kind, and conventional oils used in cosmetic compositions may be used. Specifically, hydrocarbon-based oils including squalane and mineral oil; Caprylic / capric triglycerides, neopentyl glycol dicaprate, 2-octyldodecyl myristate, isopropyl myristate, cetyl 2-ethylhexanoate, octyldodecanol, and glyceryl triethylhexanoate Ester oil containing; Vegetable oils including olive oil, jojoba oil and macadamia oil; And it is preferable to use at least one selected from the group consisting of silicone oils including cyclomethicone and dimethicone. In addition, mineral oils, animal oils, synthetic oils, and the like known in the art may be used in some cases.

Cosmetics according to the invention may comprise an organic sunscreen, said organic sunscreen for example octylmethoxycinnamate, octylsalicylate, octocrylene, butylmethoxydibenzoylmethane, oxybenzone, octyltria It is preferable to select at least one member from the group consisting of zone, menthyl anthranilate, 3,4-methylbenzylidene kempfer, methylenebis-benzotriazolyltetramethylbutylphenol and bis-ethylhexyloxyphenol methoxyphenyltriazine. . However, the present invention is not limited thereto, and any substance permitted to be used by the KFDA may be used as the organic sunscreen of the present invention.

On the other hand, the present invention, the powder portion (A) is 59.5 to 95 parts by weight of the extender pigment based on 100 parts by weight of the total powder portion; 0 to 0.5 parts by weight of a pigment pigment; And 5 to 40 parts by weight of an inorganic sunscreen, wherein the oil binder portion (B) provides a powdery sunscreen cosmetic, characterized in that it comprises an oil, an organic sunscreen or a mixture thereof.

In addition, the powder portion (A) is 99.5 to 100 parts by weight of the extender pigment based on 100 parts by weight of the total powder portion; And 0 to 0.5 parts by weight of the coloring pigment, the oil binder (B) provides a powdery sunscreen cosmetics, characterized in that it comprises 50 to 100 parts by weight of organic sunscreen and 0 to 50 parts by weight of oil. In this case, since the organic sunscreen itself is an oil component, it may play a binding role of the powder portion A, and thus may not contain oil separately. However, it is preferable to use oil in combination with an organic ultraviolet blocker for the feeling of use and sufficient binding of the powder part (A).

The present invention is also based on the surprising finding that the addition of sunscreen boosters can dramatically improve the sunscreen effect of other organic sunscreens (or combinations of organic and inorganic sunscreens) included in the composition.

Organic sunscreen alone is difficult to achieve the desired level of high UV protection. In addition, by introducing inorganic sunscreen agents such as titanium dioxide and zinc oxide to increase their content, the ultraviolet ray blocking ability can be increased, but clouding phenomenon is caused, and the rough and stiff feeling of use becomes a problem. In this case, the addition of a sunscreen effect promoting agent can solve the above problems at the same time. In other words, by including the sunscreen efficacy promoter to reduce the amount of inorganic sunscreen while using an organic sunscreen content in a lower than the usual level or required level, it is not sticky, convenient to use, and hardly cause cloudiness. It is possible to provide a powdery sunscreen cosmetic.

Therefore, the present invention, the powder part (A) is 59.5 to 95 parts by weight of the extender pigment based on 100 parts by weight of the total powder part; 0 to 0.5 parts by weight of a pigment pigment; 1 to 20 parts by weight of an inorganic sunscreen; And 0.1 to 20 parts by weight of a sunscreen efficacy promoter; The oil binder portion (B) provides a powdery sunscreen cosmetic, characterized in that it comprises an oil, an organic sunscreen or a mixture thereof.

Although sunscreens can have sunscreens on their own, their blocking properties are not as high as other sunscreens, and when combined with other sunscreens, especially organic sunscreens, they show a dramatic boost in sunscreen activity. Mean material.

In the cosmetics according to the present invention, the sunscreen potentiator is methylenebis-benzotriazolyltetramethylbutylphenol, vanilla tahitensis fruit extract, chicory root extract, disodiumphenyldibenzimidazoletesulfonate, butylmethok It is preferable to select at least one from the group consisting of cidibenzoylmethane, bis-ethylhexyloxyphenol methoxyphenyl triazine, octyl trizone, 2-phenylbenzimidazole-5-sulfonic acid, benzophenone-3 and the like. .

Such an sunscreen efficacy promoter, preferably an methylenebis-benzotriazolyltetramethylbutylphenol, more preferably an methylenebis-benzotriazolyltetramethylbutylphenol coated organic sunscreen agent whose efficacy can be promoted by Glyceryl pava, drometrizole, digaloyltrioleate, 3- (4-methylbenzylidene) campa, menthylanthranilate, benzophenone-3, benzophenone-4, benzophenone-8, butylmethoxydibenzoyl Methane, synoxate, octocrylene, octyldimethylpava, octylmethoxycinnamate, octylsalicylate, octyltrizone, paraaminobenzoic acid, 2-phenylbenzimidazole-5-sulfonic acid, homosalate, draw Methrizoltrisiloxane, disodiumphenylbenzimidazoletesulfonate, bisethylhexyloxyphenolmethoxyphenyltriazine, isoamyl-p-methoxycinnamate and the like can be used, in particular organic ultraviolet The octyl methoxycinnamate, considering the degree of promotion efficacy of blocking agent is more preferable.

In particular, methylene bis-benzotriazolyltetramethylbutylphenol as such a sunscreen efficacy promoter is superior to other sunscreen efficacy promoters. Therefore, in the cosmetics according to the present invention, particularly as the sunscreen effect promoter, methylenebis-benzotriazolyltetramethylbutylphenol [50 parts by weight of aqueous dispersion of methylenebis-benzotriazolyltetramethylbutylphenol of Ciba Specialty Chemical Co., Ltd. (Brand name: Ciba Tinosorb M)] is preferably used.

Such a sunscreen efficacy promoter, preferably methylenebis-benzotriazolyltetramethylbutylphenol, is more preferably used as a sunscreen efficacy promoter coating powder.

When methylenebis-benzotriazolyltetramethylbutylphenol itself is used in the cosmetic composition instead of the methylenebis-benzotriazolyltetramethylbutylphenol coated powder, methylenebis-benzotriazolyltetramethylbutylphenol aggregates during manufacturing or storage and There may be a problem that the effect of promoting the efficacy of the sunscreen is inferior. More specifically, in the case of methylenebis-benzotriazolyltetramethylbutylphenol, the difference in ultraviolet ray blocking ability is remarkable depending on the particle size range. The optimum particle size range is 130 ~ 180nm. When the raw material is used alone, the particle size increases due to the aggregation of the raw material itself. Therefore, it is necessary to uniformly disperse in any base material to implement an effective UV blocking ability, the coating powder used in the present invention is preferable because it is uniformly coated on the powder in the state of the particle size range 130 ~ 180nm.

Such methylenebis-benzotriazolyltetramethylbutylphenol coated powder can be produced, for example, in the following manner.

Methylene bis- benzotriazolyl tetramethylbutyl phenol coating powder which is an organic-inorganic composite powder can be manufactured through the water-based wet process process using 50 weight part aqueous dispersion of micronized methylenebis- benzotriazolyl tetramethyl butylphenol. For example, talc can be used as a powder used as a mother powder. First, talc, which is a parent powder, is added, and then 50 parts by weight of an aqueous dispersion of methylene bis-benzotriazolyltetramethylbutyl phenol is added as much as 30 parts by weight of the talc content, and 8 parts by weight of the talc content. Add aluminum hydroxide as much as needed and stir. Subsequently, filtration and washing are repeated to remove the dispersant and the like contained in the 50 parts by weight aqueous dispersion of the finely divided methylenebis-benzotriazolyltetramethylbutylphenol. 1 is an electron micrograph of methylene bis-benzotriazolyltetramethylbutylphenol-coated talc prepared according to the above-described manufacturing process and subjected to washing and dry grinding. The content of methylenebis-benzotriazolyltetramethylbutylphenol in the obtained methylenebis-benzotriazolyltetramethylbutylphenol coated talc was usually 8 to 9% by weight as a result of measurement by the liquid chromatography method.

The material used as the base powder in such methylenebis-benzotriazolyltetramethylbutylphenol coated powder can be used as long as it is a powder commonly used in cosmetic compositions, but a plate-like sieving pigment is preferable. Talc, mica, sericite, barium sulfate, calcium carbonate, silica or mixtures thereof are more preferred, and talc is most preferred.

The content of methylenebis-benzotriazolyltetramethylbutylphenol in the methylenebis-benzotriazolyltetramethylbutylphenol coated powder is preferably 5 to 20% by weight. When the content is less than 5% by weight, it is difficult to perform uniform surface treatment over the surface area of the mother powder. When the amount exceeds 20% by weight, the methylene bis-benzotriazolyltetramethylbutylphenol may be deteriorated due to the aggregation of particles.

On the other hand, the present invention also the powder part (A) is 59.5 to 95 parts by weight of the extender pigments relative to a total of 100 parts by weight of the powder part; 0 to 0.5 parts by weight of a pigment pigment; 1 to 20 parts by weight of an inorganic sunscreen; And 0.1 to 20 parts by weight of the powdery organic sunscreen, wherein the oil binder (B) provides a powdery sunscreen cosmetic, characterized in that it comprises an oil, an organic sunscreen or a mixture thereof.

In the cosmetics according to the present invention, the powdery organic UV blocker is methylenebis-benzotriazolyltetramethylbutylphenol, disodiumphenyldibenzimidazoletesulfonate, butylmethoxydibenzoylmethane, bis-hexylhexyloxyphenolmethoxyphenyl Preference is given to using powdered organic sunscreens of triazine, octyltrizone, 2-phenylbenzimidazole-5-sulfonic acid, benzophenone-3 or mixtures thereof. Powdering of the organic sunscreen can be prepared by methods commonly known in the art. For example, an organic sunscreen agent prepared in a liquid dispersed phase, such as talc, in a liquid dispersed phase, for example, an MBBT aqueous dispersion (trade name: TINOSORB M, manufactured by CHIBA SPECIALTY CHEMICAL), can be wet-treated with water (stirring, Filtration, washing, and / or grinding), but is not limited thereto.

By including the powdered organic sunscreen, the organic liquid sunscreen content can be used at a level lower than the normal level or lower than usual, while the inorganic sunscreen content can be reduced, so it is not sticky, convenient to use, and does not cause cloudiness. Powdery sunscreens can be provided.

The composition according to the invention may further comprise a nonionic surfactant. The nonionic surfactant is preferably to use a lipophilic nonionic surfactant to improve formulation stability. Specifically, the nonionic surfactant is one selected from the group consisting of glyceryl stearate, sorbitan sesquioleate, sorbitan stearate, sorbitan sesquiisostearate, PIG-10 dimethicone, and sorbitan sorbate. It is preferable that it is above.

In addition, the cosmetic according to the present invention preferably comprises 0.5 to 10 parts by weight of the nonionic surfactant based on 100 parts by weight of the total cosmetics. That is, the nonionic surfactant is preferably included 0.5 wt% or more in consideration of formulation stability, it is preferable to include 10 wt% or less for the feeling of use.

In addition, the powdery sunscreen cosmetic composition according to the present invention may further include perfumes, pigments, preservatives, fungicides, oxidative stabilizers, pearls and the like within the range that does not degrade the effect of the composition in addition to the above components.

As shown in the above description and the following examples, the powdery cosmetic composition according to the present invention has a very high level of UV blocking ability (SPF 50+, PA +++) and effectively blocks ultraviolet rays even when exposed to ultraviolet rays after makeup. At the same time, since it is composed of pigments of low refractive index with high transparency with little use of coloring pigments, it is transparent and does not appear cloudy. In addition, there is no sticky feeling compared to sun cream, sun lotion, and sun balm, and it can be applied anytime, anywhere, and can be modified cosmetics, which is the best strength of the powder sunscreen cosmetics.

The present invention also provides an organic sunscreen agent (or organic and inorganic) by using a sunscreen potency promoter, preferably methylenebis-benzotriazolyltetramethylbutylphenol, more preferably methylenebis-benzotriazolyltetramethylbutylphenol coated powder. By reducing the content of the sunscreen), less stickiness, cloudiness does not appear, and powdery sunscreen cosmetics can be prepared.

1 is an electron micrograph of methylene-bisbenzotriazolyltetramethylbutylphenol coated talc.

Hereinafter, examples and the like will be described in detail to help understand the present invention. However, embodiments according to the present invention can be modified in many different forms, the scope of the invention should not be construed as limited to the following examples. Embodiments of the present invention are provided to more fully describe the present invention to those skilled in the art.

In the following examples according to the present invention MBBT means methylene bis- benzotriazolyl tetramethylbutyl phenol, BEMT means bis-hexyl oxyphenol methoxy phenyl triazine, BMDBM is butyl methoxy dibenzoyl Methane.
