Description

Translucent cosmetic composition {A translucent cosmetic composition}

It relates to a translucent cosmetic composition.

In the conventional prescription for preparing a solid foundation, most of them contain zinc oxide and titanium oxide, which are inorganic raw materials, as sunscreen components. Patent Document 1 discloses a transparent solid sunscreen cosmetic composition, but includes both organic sunscreen and inorganic sunscreen. However, when emulsifying products were implemented with such existing functional prescriptions, transparent or translucent colors could not be realized due to the white raw materials zinc oxide and titanium dioxide.

In addition, due to the nature of the emulsified product, it is not easy to prepare a transparent cosmetic composition because the more the water content, the more the emulsion becomes bluish. In order to improve this, if the content of water is reduced, the amount of lubricant must be increased by the amount of reduced water, and as a result, the emulsion phase decreases and the emulsion stability decreases, resulting in a problem that the formulation becomes unstable.

Therefore, there is a need to develop a cosmetic composition that improves transparency or translucency and has excellent feeling of use.

Republic of Korea Patent Publication No. 2011-0072639

One aspect is an organic sunscreen; Purified water; And by including a polyol improves the transparency, provides a translucent cosmetic composition excellent in the feeling of use such as gloss, moisturizing.

Another aspect provides a method for preparing the translucent cosmetic composition.

One aspect is an organic sunscreen; Purified water; And it provides a translucent cosmetic composition comprising a polyol.

The term "translucent" refers to a state in which the shape and color are partially changed when viewing an object through a medium, and "transparent" does not change the shape and color when viewed through a medium. It means the visible state. The cosmetic composition according to an aspect of the present invention is expressed as a translucent cosmetic composition because almost no object is completely transparent, but this substrate is not completely excluded from being transparent. Thus, the terms "translucent" or "transparent" may be used interchangeably herein.

Functional ingredients for sunscreen can be divided into organic sunscreens and inorganic sunscreens. Inorganic sunscreens such as zinc oxide and titanium dioxide have a white color, making it difficult to implement transparent or translucent colors. Accordingly, the cosmetic composition according to an aspect of the present invention improves the transparency of the cosmetic composition by using only an organic sunscreen, not including an inorganic sunscreen as a sunscreen functional component. Therefore, the cosmetic composition may be an inorganic sunscreen agent-free cosmetic composition.

The term, "inorganic sunscreen agent-free" means a formulation in which an inorganic raw material, such as zinc oxide, titanium dioxide, etc., is not used among the sunscreen functional ingredients.

The translucent cosmetic composition according to an aspect of the present invention may be an emulsion formulation. Due to the characteristics of emulsifying products such as emulsion formulations, the higher the water content, the more turbidity increases and becomes cloudy. Therefore, the cosmetic composition according to an aspect of the present invention may be improved in transparency by increasing the content of polyol instead of minimizing the content of purified water to less than 15% by weight, preferably less than 10% by weight.

In addition, the translucent cosmetic composition according to an aspect of the present invention uses an organic sunscreen instead of an inorganic sunscreen as a sunscreen functional component, and increases the content of polyol instead of minimizing the content of purified water, thereby improving gloss and moisture. It can be excellent.

Accordingly, one aspect according to the present invention, based on the total weight of the composition, 15 to 30% by weight of organic sunscreen; 1 to 15% by weight of purified water; And it provides a translucent cosmetic composition comprising 9 to 30% by weight of a polyol. In another embodiment, the translucent cosmetic composition, based on the total weight of the composition, 20 to 25% by weight of an organic sunscreen; 1 to 10% by weight of purified water; And 15 to 30% by weight of polyol.

The organic sunscreen is ethylhexylmethoxycinnamate, ethylhexyl salicylate, octocrylene, homosalate, ethylhexyltrizone, diethylaminohydroxybenzoylhexylbenzoate, octylmethoxycinnamate, isoamyl- from the group consisting of cinnamate derivatives of p-methoxycinnamate, butylmethoxydibenzoylmethane, bisethylhexyloxyphenolmethoxyphenyltriazine, salicylic acid derivatives of octyl salicylate, PABA derivatives, benzophenones, and anthranilates It may be one or more selected, but is not limited thereto. In one embodiment, the organic sunscreen is from a group consisting of ethylhexylmethoxycinnamate, ethylhexyl salicylate, octocrylene, homosalate, ethylhexyltrizone, and diethylaminohydroxybenzoylhexylbenzoate. It may include one or more selected or all six. The content of the organic sunscreen may be used in accordance with the cosmetic ingredients functional permission.

In one embodiment, the translucent cosmetic composition is 15% by weight or less, less than 15% by weight, 1 to 15% by weight, 5 to 15% by weight, 10% by weight or less, less than 10% by weight, 1 to 10% by weight of the total composition And 5 to 10% by weight of purified water. When the content of purified water exceeds 15% by weight, opacity increases, and thus it may be difficult to implement a transparent or translucent cosmetic composition.

The terms "polyol", and "polyhydric alcohol" are used interchangeably and mean an aliphatic compound having two or more hydroxyl groups (-OH). The polyol may be glycerols, glycols, or a combination thereof, but is not limited thereto.

The glycerol may be glycerin, diglycerin, polyglycerin, glycerol, glycyl alcohol, or a combination of two or more thereof, but is not limited thereto. The glycerin may be mixed with other commonly used names such as lysine, propane-1,2,3-triol, 1,2,3-propenetriol, and trihydroxypropane.

Thus, the polyol is glycerin, diglycerin, polyglycerin, glycerol, glycyl alcohol, propylene glycol, dipropylene glycol, butylene glycol, diethylene glycol, triethylene glycol, hexylene glycol, pentylene glycol, and polyethylene glycol It may be one or more selected from the group consisting of, but is not limited thereto.

In one embodiment, the translucent cosmetic composition may include at least 9% by weight, 9% by weight to 30% by weight, 10% by weight to 30% by weight, or 15% by weight to 30% by weight of polyol based on the total weight of the composition have. In order to reduce the water content in order to improve the transparency of the cosmetic composition, if the lubricant content is increased without increasing the content of the polyol, as a result, the emulsion phase decreases while the emulsion stability decreases and the formulation may become unstable. Therefore, when the content of the polyol is out of the above content range, formulation stability may be reduced.

The translucent cosmetic composition according to an aspect of the present invention may further include a wax. The wax may select a suitable type and content to prepare a cosmetic composition in a solid form. In one embodiment, the cosmetic composition may further include 5 to 10% by weight of wax based on the total weight of the composition.
