Description

Cosmetic composition for high temperature stability {Cosmetic composition for lip makeup with high temperature stability}

It relates to a lip makeup cosmetic composition.

There are various kinds of cosmetics for lip makeup, including lipstick, lip gloss, lip tint, and lip locker. The cosmetics for lip makeup have been developed in consideration of color development, application, sustainability, adhesion, coverage, formulation, etc. Recently, a liquid type with high color development has been preferred in light formulations.

However, the existing liquid type lip makeup cosmetics have a problem that the high temperature stability is not good using low viscosity oil, and there is a limitation that the color is smeared and applied because it is thinly applied during application.

Accordingly, there is a need for development of a lip makeup cosmetic composition having excellent high temperature stability and maintaining liquid applicability and excellent makeup function such as adhesion and covering power.

One aspect provides a lip makeup cosmetic composition having excellent high temperature stability and excellent lip coverage, color sustainability, spreadability and adhesion by including rice bran wax and plate powder.

One aspect provides a lip makeup cosmetic composition comprising rice bran wax and plate-like powder.

The cosmetic composition includes rice bran wax and plate-like powder together with high temperature stability, excellent skin (eg, lips) coverage and color sustainability. Good high temperature stability may mean that the components in the composition do not separate at high temperatures and that the formulation is well maintained. Skin coverage may refer to the ability to cover blemishes of the skin. The color persistence may mean that the color of the lip makeup becomes less pale or disappears over time, thus maintaining the color. In addition, the cosmetic composition is excellent in the application and adhesion as compared to the case containing only one of the two by including together rice bran wax and plate-like powder. The excellent applicability may mean that the cosmetic composition is lightly applied or uniformly applied to the lips. Excellent adhesion may mean a high degree of adhesion to the lips by applying a thin coating on the skin surface when the cosmetic composition is applied to the lips.

The term “high temperature” may mean a temperature that is relatively higher than room temperature. For example, "high temperature" may mean a temperature of 30 ℃ or more.

The term "room temperature" may have a conventional meaning and may mean, for example, 20 to 30 ° C.

The term "Oryza Sativa (Rice) Bran Wax" means a wax obtained by separating and purifying rice bran oil of rice and Oryza sativa .

The cosmetic composition is 0.5 to 3.0% by weight, 0.5 to 2.5% by weight, 0.5 to 2.0% by weight, 1.0 to 3.0% by weight, 1.0 to 2.5% by weight, 1.0 to 2.0% by weight, 1.5 to 3.0% by weight relative to the total weight of the composition Weight percent, 1.5 to 2.5 weight percent, or 1.5 to 2.0 weight percent. When the cosmetic composition does not include rice bran wax and rice bran wax of the plate-like powder, the high temperature stability is very low, the composition may be separated at more than 37 ℃, even stability at room temperature may be poor. When the content of rice bran wax is less than 0.5% by weight, the effect of high temperature stability by rice bran wax may not be large. If the content of rice bran wax is less than 1.0% by weight may not be stable at high temperatures of 45 ℃ or more. If the content of the rice bran wax is 1.0% by weight or more, it may be excellent in stability at a high temperature of more than 37 ℃ as well as room temperature. If the content of the rice bran wax is more than 2.0% by weight, the stability may be very excellent because no separation phenomenon occurs even if the product is stored for 14 days at a high temperature of 37 ° C. or higher. If the content of rice bran wax is more than 3.0% by weight may not exhibit a light coating property because of poor application.

The "plate-shaped powder" is used interchangeably with "plate-shaped powder".

The cosmetic composition may include 10 to 35% by weight, 10 to 30% by weight, 15 to 35% by weight, 15 to 30% by weight, 20 to 35% by weight, or 20 to 30% by weight based on the total weight of the composition. Can be. When the cosmetic composition does not include the plate-like powder of rice bran wax and plate-like powder or contains less than 10% by weight of the plate-shaped powder, the skin coverage may not be good or adhesion may be reduced. When the content of the plate powder is 10% by weight or more, the skin coverage may increase as the content of the plate powder increases. When the content of the plate-like powder exceeds 35% by weight, the amount of powder is too large, it is difficult to mix the oil-dispersed type composition may not be manufactured.
