Description

UV blocking cosmetic composition prepared by being impregnated in urethane foam}

The present invention relates to a sunscreen product which can effectively apply an active ingredient to the skin by impregnating a low viscosity water-in-oil (W / O emulsion) sunscreen cosmetic composition into a foamed urethane foam, and is easy to use and carry. .

Ultraviolet rays irradiated from sunlight are a major cause of erythema, edema, freckles, and skin cancer. Recently, many studies have been conducted on various skin diseases caused by ultraviolet rays.

In general, ultraviolet rays are classified into UV-C, a wavelength of 240 to 280 nm, UV-C for a wavelength of 280 to 320 nm, and UV-A for a wavelength of 320 to 400 nm. UV-C passes through the ozone layer and disappears without reaching the surface. UV-B penetrates to the skin's epidermis, causing erythema, freckles, and edema. UV-A is well known to induce skin aging and skin irritation such as penetrating the dermis of the skin and promoting skin cancer, wrinkles and melanin formation.

The public's interest in the sun protection product market has increased considerably, and as a result, sun protection products with various types of sun protection index (SPF) are on the market. Types of sunscreen products are generally made of creams or lotions, depending on the composition of the inner and outer wounds of the emulsion, W / O (water in oil) and O / W (oil in water) It can be divided into

Conventionally, the sunscreen products have been widely used in summer, but recently, due to the change in lifestyle due to the increase in the population enjoying leisure life and the increasing awareness of the harmfulness of ultraviolet rays, the demand for the use of four seasons as well as summer Growing. Accordingly, consumer demand for products that enhance usability and convenience is on the rise.

Generally, sunscreen products are manufactured in the form of W / O with the oil in the external phase to enhance the water resistance to sweat or water. In the case of O / W type sunscreen products, the feeling when applied to the skin has a refreshing advantage over W / O type products, but it is still easy to wash away with sweat or water despite continuing research to improve water resistance. The disadvantage is that the persistence of the sunscreen effect, which is the conventional purpose of sunscreen products, is markedly inferior.

On the other hand, W / O type UV protection products are generally more durable than O / W type UV protection products, but have a disadvantage in that they are heavy and sticky, regardless of the high viscosity of W / O type UV protection products. Not. This is because the W / O sunscreen products are manufactured at high viscosity by increasing the ratio of the water phase, which is an inner wound, in order to adjust the feeling lightly. In addition, W / O type makeup cosmetics are generally known to have lower emulsion stability than O / W type makeup cosmetics. In particular, low viscosity W / O products are distributed in containers for long periods of time in the container during distribution. There is a problem that the separation of the product falls stability. Therefore, the viscosity is increased in order to increase the stability and if the viscosity is increased, the usability is heavy and sticky.

In a similar study to the present invention, W / O type UV protection products are contained in tube or pump formulations by adjusting the viscosity and adjusting the usability of W / O type UV protection products, but they are relatively inconvenient to carry and use. Discomfort occurs in the back. In addition, especially in the summer, the cold feeling of lowering the heat of the skin is more preferred, but when the product of the above formulation is finally applied to the skin, it is floated and applied by hand. The product gets in your hands, causing you to have to wash your hands again to prevent contamination and stickiness.

The inventors of the present invention impregnated a low viscosity sunscreen composition of W / O type in a foamed urethane foam and put it in a fact type container to secure product stability while maintaining good portability and sustaining the sunscreen effect. It does not need to be washed and there is a cooling effect, so it is easy to use and easy to use.

Therefore, the present invention provides a sunscreen product having good sunscreen effect and easy to use and carry.

In order to achieve the above object, the present invention provides a sunscreen cosmetic composition of the fact formulation in which the sunscreen composition is impregnated in the foamed urethane foam.

The sunscreen composition is characterized in that the water-in-oil type.

In addition, the present invention provides a cosmetic container containing a foamed urethane foam impregnated with the cosmetic composition.

The W / O emulsified sunscreen cosmetic composition according to the present invention is impregnated into a foamed urethane foam, and then packaged in a container of a fact type. It is possible to provide a sunscreen cosmetic composition having enhanced stability, portability and simplicity, and a cooling effect.

2 is a photograph showing the results when Example 1 and Comparative Example 1 were stored at 50 ° C. for 2 hours.

The present invention is a fact-type formulation containing a foamed urethane foam impregnated with a low viscosity W / O (water-in-oil) emulsion sunscreen composition containing an oily component, an emulsifier, an organic or inorganic sunscreen, a pigment and an aqueous phase component. .

The oily ingredients used in the present invention are vegetable oils such as rosehip oil, safflower oil, peach seed oil, meadowfoam seed oil, sunflower seed oil, dicaprylylcarbonate, squalane, neopentylglycoldiheptanoate, tocopheryl Acetate, trioctanoin, C12-15 alkylbenzoate, C12-15 alkylethylhexanoate, octyldodecylmyristate, tricapryline, octyldodecylstearoylstearate, bis-hydroxyethoxypropyldimeth Chicon, caprylic / capric triglyceride, isotridecyl isononanoate, polyglyceryl-2 triisostearate, diisostearyl maleate, dipentaerythrite patty acid ester, cetyloctanoate, ozo Synthetic esters such as kerite or silicone oils such as hydrocarbons, phenyltrimethicone, cyclomethicone, dimethicone and decamethylcyclopentasiloxane Up to more than one selected species, it is contained in an amount of 20 to 80% by weight relative to the total weight of the composition. If the oil component is less than 20% by weight, the stability of the composition is not good or the viscosity is too high because the use is heavy and sticky, the usability is not good, if it is more than 80% by weight is not good stability.

The emulsifier used in the present invention is suitable for nonionic surfactants having a low HLB with a HLB range of 1 to 6 so as to prepare a W / O emulsion, specifically cyclopentasiloxane and PEG / PPG-18 / 18 dimethicone. (Cyclopentasiloxane and PEG / PPG-18 / 18 Dimethicone), Glycol Stearate, Sorbitan Sesquioleate, Glyceryl Oleate, Glycol Distearate, Glycol Glycol Monostearate, Glyceryl Stearate, Sorbitan Stearate, PEG-30 Dipolyhydroxystearate, PEG-10 Dimethicone ( PEG-10 Dimethicone), Cyclopentasiloxane / PEG.PPG-19.19 Dimethicone (Syclopentasiloxane / PEG.PPG-19.19 Dimethicone), Sorbitan Isostearate, Lauryl PEG.PPG-18.18 Match Lauryl PEG.PPG-18.18 Methicone, Cetyl PEG.PPG-10.1 Dimethicone, Lauryl PEG-9 Polydimethylsiloxyethyl Dimethicone, and the like. One or more selected may be used and are contained in an amount of 0.01 to 10% by weight, based on the total weight of the composition. If the emulsifier is less than 0.01% by weight the emulsion is not formed or the stability of the composition is bad, if it is more than 10% by weight of the emulsifier itself and inherent off-flavor may occur badly.

The sunscreen used in the present invention may be used individually or in combination with an organic sunscreen or an inorganic sunscreen. Specifically, as the organic sunscreen, octylmethoxycinnamate, octylsalicylate, octocrylene, butylmethoxydibenzoylmethane, oxybenzone, octyltriazone, menthylanthranilate, 3,4-methylbenzylidene camphor, Isoamyl-P-methoxycinnamate, bisethylhexyloxyphenolmethoxyphenyltriazine, methylenebisbenzotriazolitetramethylbutylphenol and the like can be used, and the inorganic sunscreen is titanium dioxide having an average particle size of 5 to 100 nm. Zinc oxide having an average particle size of 5 to 300 nm, iron oxide having an average particle size of 5 to 300 nm, or the like may be used. In this case, the larger the average particle size of the inorganic sunscreen, the greater the turbidity when applied to the skin, thereby degrading its value as a commodity. On the other hand, if the particle size is too small, it may penetrate into the skin and cause irritation. Is 300 nm or less and 10 to 50 nm is appropriate when considering skin irritation and whitening at the same time.

 In addition, the sunscreen is contained in an amount of 1 to 35% by weight based on the total weight of the composition. If the sunscreen is less than 1% by weight, the sunscreen effect is less than 10 (SPF index) or less, and if it exceeds 35% by weight, turbidity, shine, etc. are severe or there is a risk of skin irritation.

Pigments used in the present invention are components other than inorganic sunscreen, PMMA (polymethyl methacrylate), silica, nylon, polyurethane, ultramarine, iron oxide (pearl oxide), pearl, synthetic mica, mica, talc, cera One or more selected from sight and boron nitride may be mixed and used in an amount of 0.1 to 20% by weight based on the total weight of the composition. If the content of the pigment is less than 0.1% by weight, the effect of adhesion, color expression, and thickening is insignificant, and if it is more than 20% by weight, the feeling of use is stiffened due to excessive increase in viscosity and the stability of the emulsion becomes worse. .

The aqueous phase component used in the present invention may be one or more selected from purified water, propylene glycol, 1,3-butylene glycol and glycerin, and is contained in an amount of 30 to 70% by weight based on the total weight of the composition. This is because if the aqueous phase component is less than 30% by weight, the viscosity is too low to lower the stability of the formulation, and if it is more than 70% by weight, the viscosity is too high.

In addition to the above components, at least one selected from preservatives, fragrances and other additives may be further mixed into the sunscreen composition. In particular, parabens such as methyl paraben, propyl paraben, butyl paraben, and ethyl paraben may be mixed in the oil phase and in the case of phenoxy ethanol, among the materials which may be used as preservatives. The fragrance is also added to the end of the manufacturing process of the composition to the W / O oil phase.

The W / O emulsion sunscreen composition of the present invention has a low viscosity in the range of 5000 to 15000 cps. If the viscosity of the W / O emulsion composition is less than 5000 cps, separation of the oil phase and the water phase occurs immediately after the preparation of the emulsifier, and it is difficult to impregnate the uniform composition when impregnated into the urethane foam. This is because the value as a product falls.

The sunscreen composition of the present invention is contained in a container of fact type using foamed urethane foam. The fact that the container of the fact type is more portable than the tube or pump type container in terms of portability and cosmetic ease, but in the case of flowable cosmetics, the flowability of the flowable cosmetics is easy to overflow or contaminate in the container. Since urethane must be lowered sharply, foamed urethane impregnation material is incorporated. Therefore, the cosmetic composition of the present invention is applied to cosmetics of various formulations, such as water-in-oil flowable cosmetics, for example, makeup primer, makeup base, foundation, lip gloss, liquid eye shadow, eyebrow, liquid concealer, liquid blusher or airless This is easy. A fact type cosmetic container with a foamed urethane impregnated material is shown in FIG. 1.

In the case of a closed cell, the foamed urethane foam impregnated with the sunscreen composition of the present invention is preferably in the form of an open cell because bubbles are trapped in the urethane and thus do not impregnate the sunscreen composition.

In addition, the foamed urethane foam (foam) used in the present invention should be a foamed urethane foam of appropriate hardness, suitably as an open cell foam urethane foam (ASKER, manufacturer) DUROMETER HARDNESS standards Foamed urethane foams having a hardness of 10 to 70 can be used as a gauge reference (Type F). If it is too brittle, the makeup tools (usually NBR puffs) used in the fact type or the W / O emulsion makeup cosmetics impregnated with the foamed urethane foam during hand make-up will be excessive, and if it is too hard, the W / O emulsion makeup cosmetics will not come out easily. Because it becomes.

Hereinafter, the present invention will be described in more detail based on the following Examples and Test Examples. However, these examples and test examples are only for the understanding of the present invention, and the scope of the present invention in any sense is not limited to these examples.
