Problems solved by technology

[0008] According to the above, the plant essential oils used in cosmetics in the existing solutions are extremely volatile, have a short storage time, and the essential oils are difficult to dissolve in water, so that the application of essential oils in cosmetics is limited, and there are problems in the preservation and utilization of essential oils. Stabilize plant essential oils, but the preparation of plant essential oil capsules in the prior art is complicated and the capsules have poor persistence

Abstract

The invention provides persistent plant essential oil sustained-release capsules for cosmetics and a preparation method. The preparation method comprises the following steps: after mixing plant essential oil, an emulsifier and a gelatin solution, carrying out high-speed homogenization and emulsification to obtain a material A; preparing perhydropolysilazane into a solution, so as to obtain a material B; then atomizing the material A and the material B under high-pressure ammonia gas; carrying out collision and dispersion to obtain the persistent plant essential oil sustained-release capsules for the cosmetics. According to the method, silicon dioxide films are formed on the surface of plant essential oil to form the capsules; the method has a simple technology and the plant essential oil is completely and stably covered, so that persistent and sustained-release effects are realized; the plant essential oil has a long storage period and a persistent effect when being used for the cosmetics, has hydrophilicity and can be used for effectively promoting the dispersion of the plant essential oil on the cosmetics; meanwhile, the persistent plant essential oil sustained-release capsules have strong adaptability on the cosmetics and are suitable for being added into the cosmetics including sunblock, moisturizing cream, makeup cream, whitening cream, anti-ageing and beauty-maintaining cream and the like.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to a cosmetic plant essential oil composition, in particular to a sustained-release plant essential oil capsule for cosmetics and a preparation method thereof. Background technique [0002] With the improvement of living and cultural standards, beauty and hairdressing cosmetics are more and more valued by people. Because natural cosmetics have good efficacy, few side effects and no allergies, they have more advantages than synthetic cosmetics, so beauty cosmetics based on natural plant ingredients are more and more favored by consumers. Advocating green and returning to nature is the development trend of the cosmetics industry. Therefore, the research and development of cosmetics from plant resources has become an indispensable link in the sustainable development of the cosmetics industry. In recent years, there have been more and more research reports on the preparation of cosmetic agent...
