Problems solved by technology

However, due to the clogging of the valve caused by the coagulation of the powder of the inorganic ultraviolet blocking agent, there is a problem in the injection force, and the use of the inorganic ultraviolet blocking agent is limited, and it is difficult to expect a high ultraviolet blocking effect.
Therefore, Butyloctyl Salicylate (Butyloctyl Salicylate) or film-forming agent, silicon dioxide and other powders are used as UV blocking enhancers to improve the UV blocking index, but the UV blocking coefficient is not higher than that of inorganic UV rays. In addition, even if an inorganic UV blocking agent is used, a large amount of inorganic UV blocking agent cannot be used because the valve is clogged, so it is difficult to expect UV blocking like ordinary cream or emulsion type by spray type. The effect that the blocking index is SPF50 and the ultraviolet A blocking level is PA+++ or higher
[0007] Also, Korean Laid-Open Patent No. 10-2013-0048886 has the problem that when an inorganic ultraviolet blocking agent is applied to a spray type dosage form or wet skin having a high ultraviolet blocking index, condensation or white turbidity is serious, and sticking to clothes case, has the disadvantage of producing white stains

Embodiment 1 to Embodiment 4

[0042] Examples 1 to 4: Transparent spray organic violet based on oil and ethanol composition Preparation of external ray blocking agent

[0043] Examples 1 to 4 are formulations in which the composition of the oil phase, ethanol, etc. is changed to optimize viscosity, cooling feeling, and spraying power for the preparation of spray-type ultraviolet blocking cosmetics.

[0044] According to the composition ratio in the following table 1, the organic UV blocker (ethylhexyl methoxycinnamate, homosalate, ethylhexyl salicylate, butylmethoxydibenzoylmethane, octyl Lin, bis-ethylhexyloxyphenol methoxyphenyl triazine) and oil phase components (simethicone, octylmethicone, cetyl dimethicone, ethyl palmitate Hexyl ester, cyclopentasiloxane (Cyclopentasiloxane, acrylate / simethicone copolymer) were heated to 80° C. and made into the same phase by dissolving, ethanol and fragrance were mixed and dissolved. Separately dissolve the organic UV blocker (phenyl benzimidazole sulfonic acid...

experiment example 1

[0059] Experimental Example 1: Feeling in use and usability on wet skin

[0060] The feeling in use and the feeling on wet skin of the ultraviolet blockers prepared according to Example 1 to Example 4 and Comparative Example 1 to Comparative Example 5 were tested.

[0061] results, such as figure 1 As shown, in Examples 1 to 4 prepared by using only an organic ultraviolet blocking agent without containing a surfactant, a mild and refreshing composition without cloudiness can be obtained. In particular, it can be seen that the compositions of Examples 1 and 2 containing a large amount of silicon and ethanol have a refreshing feeling of use and a cooling feeling, and can be applied to wet skin.

[0062] In contrast, when Comparative Example 1 was applied to wet skin, it was difficult to apply the ultraviolet blocking agent to the skin due to emulsification, and the ultraviolet blocking effect could not be expected. When Comparative Examples 2 to 3 were applied to wet skin, ...

experiment example 2

[0063] Experimental example 2: Determination of UV blocking factor (SPF), UV A blocking level (PA) Determination of

[0064] The ultraviolet blocking effect of the ultraviolet blocking agent composition prepared according to Example 1 was tested. According to the "ultraviolet blocking functional test method" in the "standard and test method of functional cosmetics" announced by the Food and Drug Administration, the ultraviolet blocking coefficient and ultraviolet A blocking grade PA were tested as follows. Tape (Transpore Tape: 3M, USA) is attached to the prepared cast, and the sample is 2 mg / cm 2 To apply the composition, and then use an ultraviolet (UV) measuring instrument (SPF 290 analyzer (Analyzer)) to measure the ultraviolet blocking effect, and the measurement of the ultraviolet A blocking grade PA uses a 300W xenon arc lamp (xenonarc lamp) installed ) as the artificial ultraviolet radiometer of light source-multi-port solar simulator (Multi-port Solarsimulator) 6...

Abstract

The invention relates to a transparent spraying type ultraviolet blocking composition containing an organic ultraviolet blocker, ethanol, oil and purified water. The ultraviolet B blocking coefficient of the transparent spraying type ultraviolet blocking composition containing the organic ultraviolet blocker, ethanol, oil and purified water is SPF50 or above, the ultraviolet A blocking grade keeps PA+++, and the composition has cooling and makeup finishing functions, has no white turbidity phenomenon, and can be used for dry skins and wet skins.

Description

technical field [0001] The present invention relates to a transparent sprayable ultraviolet blocking composition containing an organic ultraviolet blocking agent, and more specifically, to a transparent spraying ultraviolet blocking composition containing an organic ultraviolet blocking agent, ethanol, oil, and purified water. Background technique [0002] Recently, with the destruction of the ozone layer caused by environmental pollution, the amount of ultraviolet rays reaching the earth's surface has increased. Therefore, a large number of studies have been conducted on the effects of ultraviolet rays on the human body. Among them, the most representative research involves The problem of aging skin. [0003] As a method for delaying the above-mentioned skin aging phenomenon, the first method is to reduce the penetration of ultraviolet rays into the skin by using ultraviolet blocking agents. Numerous studies of UV blocking compositions for skin protection in B (UV-A, B)). ...
