Technical Field

The invention relates to the technical field of cosmetics, in particular to a lip cosmetic containing a spirulina extract and a preparation method thereof.

Background

The lipstick is a necessity in our life, and can keep the lips of our body from being dry and cracked, and has the effects of lasting moisture and long-time water locking. The basic formula of the traditional lipstick is a wax-based grease system, and the lip is moistened and water is locked by grease, so that the lip is not cracked and has the effect of tenderness and elasticity. With the improvement of living standard, people have higher and higher requirements on the efficacy of the lipstick, and some functional components are slowly added into the lipstick. However, the active substances added in the lipstick are oil-soluble or oil-dispersible components, and many water-soluble components with remarkable efficacy cannot be added into lip products, such as spirulina extracts, due to the fact that the water-soluble components are not mutually soluble in oil and water and cannot resist high temperature and are easy to inactivate.

The spirulina extract has the effects of whitening, resisting radiation, delaying aging, efficiently preserving moisture, promoting metabolism, increasing skin elasticity and the like, and belongs to water-soluble substances. Although spirulina extracts are currently used more widely in the cosmetic field. However, most of these cosmetics belong to aqueous systems and have excellent solubility in spirulina extracts. However, lip products such as lipsticks generally belong to a pure oil system, and the water phase and oil are not mutually soluble, which hinders the application of spirulina extracts in lip products. In addition, lip products such as lipstick and the like are often heated, filled for the second time and the like in the production process, but the spirulina extract is not resistant to long-term high temperature and is easy to inactivate and flocculate under the long-term high temperature, so that the phenomenon of sweating occurs in the forming process. This further limits the use of spirulina in lip products.

Disclosure of Invention

The present invention is directed to solving at least one of the problems of the prior art. Therefore, the invention provides a lip cosmetic containing spirulina extract for avoiding the phenomenon of sweating and a preparation method thereof.

In a first aspect, an embodiment of the present invention provides a lip cosmetic comprising the following components in percentage by weight:

67-91.1 wt% of oil phase matrix;

algae extract 0.5-2 wt%;

4-8 wt% of composite emulsifier;

wherein the emulsifier comprises a first emulsifier and a second emulsifier, and the first emulsifier comprises sunflower wax, jojoba wax and cercis chinensis wax; the second emulsifier comprises polyglycerol-6 distearate, jojoba ester, polyglycerol-3 beeswax ester, and cetyl alcohol.

The lip cosmetic provided by the embodiment of the invention has at least the following beneficial effects:

according to the scheme, the first emulsifier and the second emulsifier are compounded, so that the algae extract can be well compounded into the oil phase matrix.
