Description

UV block cosmetic composition of powder type

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.

Recently, the ozone layer is destroyed due to environmental pollution, and ultraviolet exposure is intensified. Such ultraviolet rays act as a main cause of erythema, edema, freckles, and skin cancer. Accordingly, the development of a product that protects the skin from ultraviolet rays has recently been required. In particular, as life improves, as well as the desire to protect the skin from the ultraviolet rays of life, as the population of leisure activities such as skiing, golf, and sea bathing increases, the demand for protecting the skin from ultraviolet rays is increasing. Research is ongoing.

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

In the past, long-wave ultraviolet (UV-A) has been welcomed for its effectiveness in treating inflammation, but recently, skin deterioration due to degeneration of proteins in the dermis, capillary expansion, and destruction of nucleic acids (DNA) has been promoted. It is pointed out. Meanwhile, the medium-wave ultraviolet (UV-B), which is mostly absorbed from the epidermal part of the skin, acts rapidly on the epidermis and causes burns, which is also called harmful ultraviolet. The long-wave UV rays come into contact with the skin all year round, but there is no self-awareness, and the skin grows old without you knowing it.

The public's interest in sun protection products has increased as the risks of sun exposure have increased, and therefore products with various sun protection factors (SPF) and protection grade of UVA (PA). Is being 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 no choice but to use large amounts of sunscreen ingredients to achieve high levels of sunscreen protection. The sunscreen is basically an inorganic sunscreen such as titanium dioxide, zinc oxide, zirconium oxide or octylmethoxycinnamate, octylsalicylate, octocrylene, butylmethoxydibenzoylmethane, oxybenzone, octyltriazone, menthylanthra Organic sunscreens such as nylate and 3,4-methylbenzylidene camphor. In the case of inorganic sunscreens, there is a problem of cloudiness, and in the case of organic sunscreens, most of liquids having a very high viscosity in themselves are sticky or must be used together with oils having a high viscosity as their solvent. . Therefore, conventional sunscreen products are manufactured in the form of creams or lotions, but such stickiness significantly reduces the feeling of using sunscreens.

Recently, sunscreen products have been made in solid form using wax and sunscreen products have been applied to the face using puffs. 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, it is difficult to apply a conventional lotion or cream product or waxy solid product because of stickiness, and in particular, when applying over makeup make-up, it is almost impossible to apply it because of the fatal disadvantage that the make-up collapses.

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.

Still another object of the present invention is to produce a sunscreen in the form of powder, when using a large amount of inorganic sunscreen is caused a hazy cloudy appearance of the skin, excessive amount of organic sunscreen in order to lower the content of the inorganic sunscreen When not in use, the formulation is not formed in the powder form, but also causes stickiness in use, thereby providing a powdery sunscreen composition which hardly causes stickiness and cloudiness.

In order to achieve the above technical problem, the present invention can be applied freely without causing stickiness, and in order to develop a sunscreen composition having a high sunscreen effect, by using a relatively large amount of liquid phase while containing a large amount of powdery feeling Provided are sunscreen compositions for the manufacture of good powder forms.

The sunscreen cosmetic according to the present invention sprays and blends 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 a penetration of 5-65 (JIS K 6301, It is manufactured from Pau phase of Asker JAL Type), and characterized in that the UV protection index (SPF) is 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, and more preferably, the cosmetic according to the present invention is prepared through a process of sieving and / or aged before the tableting or compression process.

Can be. 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 make sunscreens.

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 there is a possibility that the mixture of the uniformly mixed powder portion A and the oil binder portion B may contain foreign particles or agglomerated particles of the mixture, the mixture is subjected to compression molding or baked molding before performing compression molding or baked molding. The filtering may be further performed by using a mesh having a specific size, for example, a size that allows the mixture particles to pass but does not allow foreign matter or agglomerated particles to pass.

In addition, if the mixture of the uniformly mixed powder portion A and the oil binder portion B is directly compression molded or baked, uneven pores are generated due to the air present between the mixture particles, thereby cracking the product. In order to solve this problem, it may be desirable to perform a aging process in which the mixture is left for a predetermined time or more to remove non-uniform pores 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, depend on the hardness conditions. Variations in molding conditions may be readily selected by one skilled in the art depending on 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.
