Description

Lip cosmetic composition {LIP COSMETIC COMPOSITION}

The present invention relates to a lip cosmetic composition, and more particularly, to a lip cosmetic composition that can prevent bleeding from the lips.

In general, the majority of cosmetic compositions including lip cosmetic compositions such as lipstick, lip gloss, lip balm, and lip pencil serve to protect the skin by making it look beautiful by giving color to the skin. Mainly disperse various nutrients, organic and inorganic pigments useful for the skin into oily substances such as animal and vegetable waxes and ester oils to form a uniform mixture.

Lip gloss, a kind of lip cosmetic composition, is composed of oil, wax, and pigment, which are oily ingredients, and is used to provide a softening effect and color expression effect on the lips.

Since the early 1990s, lip gloss with improved persistence has been developed in various forms to improve the disadvantages of ordinary lip gloss.

Lip gloss compositions prepared by mixing volatile oils with film-forming polymers, waxes, powders, etc., have excellent durability, but volatile oils volatilize over time, resulting in a relatively high content of waxes and powders, resulting in dry lips. have.

In the case of the lip gloss composition prepared by mixing an organosiloxane resin, a high viscosity dimethicone, and a volatile oil, the film film made after the volatile oil is volatilized can prevent evaporation of moisture on the lips and does not include wax, thereby overcoming the above problems. It became. However, the compatibility of the mixture is poor and the contents are separated by the change over time, causing problems in stability, not only the formulation of the lip gloss, but also in the form of the container, storage conditions, handling, etc. have been followed.

In order to solve the above problems, it provides a non-staining lip cosmetic composition with excellent stability, moisturizing power.

Lip cosmetic composition according to embodiments of the present invention may include diphenyldimethicone, trimethylsiloxysilicate, and dextrin palmitate.

The lip cosmetic composition may include 5 to 60% by weight of the diphenyl dimethicone, 0.1 to 10% by weight of the trimethylsiloxysilicate, and 0.1 to 10% by weight of the dextrin palmitate.

The lip cosmetic composition may further comprise 10 to 20% by weight of octyldodecanol.

The lip cosmetic composition may further comprise 5 to 60% by weight of volatile oil.

The volatile oil may comprise isododecane.

The lip cosmetic composition may have a formulation of lip gloss.

According to the embodiments of the present invention, it is possible to minimize discoloration, discoloration, and oil separation by excellent stability according to the change over time, and provides excellent moisturizing power by increasing the mixing stability of volatile oil and powder. In addition, since the lip cosmetic composition according to the embodiments of the present invention reduces the content of wax, it is possible to express vivid colors and form a thin film on the lips so as not to be buried well.

Hereinafter, the present invention will be described in more detail with reference to the following examples. The objects, features and advantages of the present invention will be easily understood by the following embodiments. The present invention is not limited to the embodiments described herein, but may be embodied in other forms. The embodiments disclosed herein are provided so that the disclosure may be thorough and complete, and that those skilled in the art will be able to convey the spirit of the invention to those skilled in the art. Therefore, the present invention should not be limited by the following examples.

Embodiments of the present invention relate to a lip cosmetic composition, which may include diphenyldimethicone, trimethylsiloxysilicate, and dextrin palmitate.

The diphenyl dimethicone is a liquid having a high viscosity at room temperature where the viscosity is present at a viscosity of 1,000 to 2,500,000 cSt (centistokes) at 25 ° C. It can provide excellent feeling of use, adhesion and spreadability without stickiness.

According to embodiments of the present invention, the diphenyldimethicone may be included in the lip cosmetic composition 5 to 60% by weight, preferably 20 to 40% by weight. If the diphenyl dimethicone is less than 5% by weight does not significantly help in improving the adhesion and spreadability of the lip cosmetics, when it exceeds 60% by weight may spread the spreadability.

The trimethylsiloxysilicate is a thickener present in powder form to increase the viscosity of the low viscosity oil and prevent separation of the powder and the general oil.

According to embodiments of the present invention, the trimethylsiloxysilicate may be included 0.1 to 10% by weight, preferably 1 to 5% by weight. If the trimethylsiloxysilicate is less than 0.1% by weight does not increase the viscosity of the oil, if it exceeds 10% by weight does not disperse to obtain the desired formulation.

The dextrin palmitate is a wax in powder form, which serves to increase the viscosity of the volatile oil, and serves to reduce the separation of the powder and the oil. According to embodiments of the present invention, the dextrin palmitate may be included in an amount of 0.1 to 10% by weight, preferably 1 to 5% by weight.

If the dextrin palmitate is less than 0.1% by weight, the viscosity of the oil cannot be increased. If the dextrin palmitate is more than 10% by weight, the viscosity is too high to obtain a desired formulation.

The trimethylsiloxysilicate and dextrin palmitate may improve the compatibility and dispersibility by maintaining a constant viscosity of the lip cosmetic composition. In addition, the lip cosmetic composition may further comprise 5 to 60% by weight of volatile oil, preferably 20 to 40% by weight may further include. If the volatile oil is less than 5% by weight, the drying speed of the lip gloss is slowed, and the bleeding phenomenon cannot be improved. If the volatile oil exceeds 60% by weight, it is difficult to mix with the raw material due to poor compatibility and the lips may be dried after application.

The volatile oil may comprise isododecane. Isododecane contained in a lip cosmetic composition, such as lip gloss, can be applied to the lips and quickly disperse into the air to form a thin, flexible film film that can improve the persistence of the lip cosmetics.

The lip cosmetic composition may further comprise 10 to 20% by weight of octyldodecanol.

Lip cosmetic composition according to embodiments of the present invention includes a high gloss lip gloss formulation, it can be made in various forms such as lip tint, lipstick, lip balm.
