Abstract

Provided is a sunscreen impregnated with a polyester foam comprising: a polyester foam with 30-70 of type F ASKER hardness; and a sunscreen composition impregnated with the same polyester foam, which contains 20-70 wt% of oil phase ingredients, 1-35 wt% of an organic sunscreen, 1-30 wt% of a pigment, 10-50 wt% of water-based ingredients, and 0.01-10 wt% of an emulsifier having a HLB value between 1 and 6 and has viscosity of 500-5,000 cps. The sunscreen of the present invention features long-lasting uniformity of the cosmetic ingredients, spreadability on the skin, and long-lasting power, thereby giving satisfaction to a user.

Description

TECHNICAL FIELD [0001] The present invention relates to an ultraviolet screening cosmetic composition impregnated with a polyester foam,

The present invention relates to an ultraviolet barrier cosmetic impregnated with a polyester foam. And particularly to an ultraviolet barrier cosmetic having an ASKER hardness of 500 to 5,000 cps impregnated with a polyester foam having a hardness of 30 to 70 on an F type basis.

Generally, the wavelength is shorter than that of visible light, and the wavelength is longer than that of X-ray and has a wavelength of 10 nm to 400 nm. These ultraviolet rays are divided into A, B and C according to the wavelength, and the ultraviolet rays C are blocked in the ozone layer. However, when the ultraviolet rays A and B are irradiated to the human body for a long period of time, It has been known for a long time. As the cosmetics for blocking ultraviolet rays, inorganic sunscreens such as titanium dioxide and zinc oxide, butylmethoxydibenzoylmethane, 4-methylbenzylidene camphor, and organic ultraviolet screening agents such as ethylhexylsalicylate have been used as cosmetic ingredients.

Such a cosmetic for ultraviolet shielding is required to have water resistance to sweat and water, and is manufactured and used as a water-in-oil type. The cosmetics of the water-in-oil type are superior to those of the underwater type, but when applied to the skin due to a large amount of oil contained in cosmetic ingredients of the water-in-oil type, the feeling of heaviness, sticky feeling, There is a problem that the component and the oil component are separated. Furthermore, in order to increase the stability of such a water-in-oil type cosmetic, the viscosity thereof is usually 10,000 cps. In this case, the feeling of use is heavy and the stickiness is low.

Conventionally, a cushion type cosmetic impregnated with a cosmetic is prepared by mixing a cosmetic composition with an oil component, a water component, a surfactant, and a cosmetic, and impregnating the porous foam with the puff.

The cushion type cosmetics manufactured in this way maintain uniformity at the initial stage of manufacture but are not uniform over time and are not satisfactory in the function of the cosmetic material, that is, the covering of skin pores and fine wrinkles, And it is also difficult to absorb the sweat and sebum of the skin to increase the make-up duration.

In order to solve the above problems, the inventor of the present invention has found that the viscosity of a cosmetic composition is reduced to 500 to 5,000 cps and the HLB value of the emulsifier is 1 to 6, In which a polyester having a hardness of 30 to 70 as an ASKER hardness and a hardness of 30 to 70 on a polyester basis is impregnated with a cosmetic composition so as to make it easy to carry and easy to carry while blending an organic ultraviolet screening agent, And the function of the cushion cosmetics can be greatly improved. Thus, the present invention has been completed.

The cosmetic of the present invention comprises 20 to 70% by weight of an oily component, 1 to 35% by weight of an organic ultraviolet screening agent, 1 to 30% by weight of a pigment and 10 to 50% by weight of an aqueous component with an emulsifier having an HLB value of 1 to 6 % By weight uniformly and then impregnated into the polyester foam to maintain the uniformity of cosmetic ingredients for a long period of time as a cushioning agent and maintain the long-lasting effect on the skin, spreadability, and cosmetics for a long time, .

Hereinafter, the configuration of the present invention will be described in more detail.

One embodiment of the present invention relates to a polyester foam impregnated with an ultraviolet light cosmetic composition.

As used herein, the polyester foam refers to a foam known in the art, and specifically refers to having a hardness of 30 to 70 on the ASKER hardness F type. In an embodiment of the present invention, the ultraviolet cosmetic impregnated with the polyester foam contains 20 to 70% by weight of a polyester foam, 1 to 35% by weight of an organic ultraviolet screening agent, 1 to 30% by weight of a pigment and 10 to 50% A water-in-oil type cosmetic composition comprising 0.01 to 10% by weight of an emulsifier having an HLB value of 1 to 6 uniformly blended therein, wherein the cosmetic composition is one or more selected from the group consisting of synthetic ester oils, hydrocarbon oils, Or more of the oil component vegetable oil.

In the above, the oily component means at least one member selected from the group consisting of vegetable oil, synthetic ester oil, hydrocarbon oil and silicone oil.

In the above, the emulsifier has an HLB value of 1 to 6, which means a nonionic emulsifier suitable for W / O emulsification.

In the above, the aqueous phase component means water, a humectant such as glycerin, an emulsifying stabilizer such as salt, a fragrance or the like.

The term "pigment" as used herein refers to polymethyl methacrylate, titanium dioxide, iron oxide, and the like.

The ultraviolet screening agent may be at least one selected from the group consisting of an inorganic ultraviolet screening agent such as titanium dioxide and zinc oxide, an organic solvent such as ethylhexylmethoxycinnamate, benzophenone, 4-methylbenzylidene camphor, methylenebisbenzotriazolyltetramethylbutylphenol, phenylbenzimidazole, And ultraviolet light blocking agents such as bis-ethylhexyloxyphenol methoxyphenyltriazine, and the like.
