[0002] Lipstick is a primitive and common cosmetic, mainly made of oil, fat, wax, pigment and other main ingredients. Lipstick is generally solid and will not overflow due to deep lip lines. It has a dry and hard texture and high color saturation. It can give lips a hue, emphasize or change the outline of the lips, and show more vitality and vigor. At the same time, lipstick has a strong color covering power, which can achieve the effect of moisturizing, protecting the lip skin and preventing lip cracking.

[0003] However, existing lipsticks often contain plant extracts, which contain many natural ingredients, and some substances are prone to crystallization in the lower temperatures of winter. Summary of the invention

[0004] The purpose of the present invention is to solve at least one of the technical problems existing in the prior art and to provide a cold-resistant lip balm and a preparation method thereof.

[0005] The technical solution of the present invention is as follows:

[0008] The microcapsule comprises a capsule wall and a core material, wherein the core material comprises a substance that inhibits the crystallization of a plant extract.

[0009] As a preferred embodiment of the present invention, the core material further comprises at least one of olive oil, tea oil and coconut oil.

[0010] As a preferred embodiment of the present invention, the substance that inhibits the crystallization of the plant extract includes polyglycerol fatty acid esters, 2-ethylhexyl stearate and phytosterol esters.

[0011] As a preferred embodiment of the present invention, the mass ratio of the polyglycerol fatty acid ester, 2-ethylhexyl stearate and phytosterol ester is 1-3:1:2-5.

[0012] As a preferred embodiment of the present invention, the plant extract includes calendula officinalis extract and camellia extract;

[0013] The natural oils include grapeseed oil.

[0014] The invention discloses a method for preparing a cold-resistant lip balm, comprising the following steps:

[0015] S1: uniformly mix the substance containing the plant extract crystallization inhibitor and at least one of olive oil, tea oil and coconut oil, mix at ultra-high speed, then homogenize, add to the chitosan solution, continue to add the Arabic solution, shake in a water bath, and finally centrifuge to obtain the precipitate to prepare microcapsules;

[0016] S2: The microcapsule, the plant extract, the beeswax and the natural oil are mixed, and then filled and packaged to obtain the product.

[0017] As a preferred embodiment of the present invention, the rotation speed of the ultra-high speed mixing is 2000-3000 rpm.

[0018] As a preferred embodiment of the present invention, the preparation method of the chitosan solution is as follows:

[0019] The chitosan is dissolved in water, 1-3 wt% acetic acid is added, and then calcium chloride is added, the pH is adjusted to neutral, and the mixture is stirred evenly to obtain the product.

[0020] The beneficial effects of the present invention are:

[0021] The cold-resistant lip balm of the present invention adds a crystallization-inhibiting substance in the form of microcapsules, so that the crystallization-inhibiting substance is slowly released and the microcrack stress generated when the temperature is lowered tears the microcapsule wall material. On the one hand, the oil substance added therein is filled, and on the other hand, the crystallization-inhibiting substance in the core material flows out, thereby reducing the crystallization of triterpene ester substances in the plant extract.
