Technical Field

The invention relates to the technical field of daily necessities, in particular to a binary system composition and a preparation method thereof.

Background

Lip gloss is an oily gel for decorating lip shape and lip color. It can not only create the effect of bright lip, but also can modify the lip to the maximum extent. At present, the commercially available lip gloss is light in color, mostly belongs to colorless and transparent oily gel, is glittering and translucent in appearance, has the advantages of moistening, brightening, lightness, thickness and the like, but has poor coverage, and is only suitable for makeup effects such as light makeup, transparent makeup or bare makeup. It is also necessary to match lipstick or lip balm to better color or modify the color of the skin on the lips. Therefore, professional cosmeticians often do not use lip gloss alone in actual work. If there is such a lip gloss product: half is sparkling and crystal clear lip gloss, and half is the bright-colored lip gloss that has the colour decorative effect, and rethread ball etc. evenly paints both to the lip in the use, so, this product will can combine together lip gloss's moistening, moisturizing, decoration and lipstick cover, the effect of coloring, directly evenly paints at the lip.

However, in the actual production process, it has been found that various defects such as color mixing and the like are likely to occur when lip gloss products of the same type and different colors on the market at present are processed. The main reason for this is that lip gloss and lipstick products have different formulations, no wax component is added in the lip gloss, and the colorless lip gloss part and the colored lip gloss part are easy to mix color under the action of external force in the processing process. Therefore, it is necessary to provide a two-part composition which is less likely to cause color mixing.
