With the continuous improvement of people's pursuit of beauty, the cosmetics industry is booming. In order to meet consumer demand for the quality and effectiveness of cosmetics, researchers are constantly exploring new extraction techniques. Among them, ultrasonic extraction technology, as an efficient and environmentally friendly extraction method, has been widely used in the cosmetics industry. This article will introduce the application of ultrasonic extraction technology in the extraction of active ingredients in cosmetics.
Second, the principle of ultrasonic extraction technology.
Ultrasonic extraction technology uses the energy of ultrasound waves to release target components from plant or animal tissues. When ultrasound comes into contact with the material, it creates strong vibration and friction that disrupts the cell wall and membrane, making it easier for the target components to be released. At the same time, ultrasound can also accelerate the mass transfer process between solvent molecules and target components, improving extraction efficiency.
3. Application of ultrasonic extraction technology in the extraction of active ingredients in cosmetics.
1.Extraction of plant active ingredients.
Plants are one of the important raw materials in cosmetics**, which contain many active ingredients with skin care, whitening, antioxidant and other effects. Ultrasonic extraction technology allows for efficient extraction of these active ingredients from plants. For example, rose essential oil in roses, tea polyphenols in green tea, etc., can all be obtained by ultrasonic extraction technology.
2.Animal active ingredient extraction.
Cosmetic raw materials for animals** have also received widespread attention, such as snake venom, algin, etc. Ultrasonic extraction techniques can be used to extract these active ingredients from animal tissues. For example, anti-wrinkle ingredients are obtained from snake venom using ultrasonic extraction technology, and moisturizing ingredients are obtained from algin.
3.Microbial fermentation product extraction.
Microbial fermentation products have a wide range of applications in cosmetics, such as yeast fermentation products, lactic acid bacteria fermentation products, etc. Ultrasonic extraction technology allows for efficient extraction of target components from microbial fermentation products. For example, ultrasonic extraction technology is used to obtain moisturizing and anti-aging ingredients from yeast fermentation products, and whitening and antioxidant ingredients are obtained from lactic acid bacteria fermentation products.
4. Advantages and limitations of ultrasonic extraction technology.
1.Advantage. 1) High efficiency: Ultrasound can quickly destroy the cell wall and cell membrane, and improve the release efficiency of the target components.
2) Environmental protection: Ultrasonic extraction technology uses non-chemical solvents, which is environmentally friendly.
3) Good repeatability: ultrasonic extraction technology is simple to operate and easy to achieve industrial production.
2.Limitations.
1) Higher equipment cost: Ultrasonic extraction equipment is usually more expensive than traditional extraction equipment.
2) Poor extraction effect of some special components: For some components with strong polarity or special structure, the ultrasonic extraction effect may not be as good as other extraction methods.
V. Conclusions and prospects.
As an efficient and environmentally friendly extraction method, ultrasonic extraction technology has a wide range of application prospects in the extraction of active ingredients in cosmetics. However, there are still some limitations to this technology, such as high equipment cost and poor extraction effect of some special components. In the future, the efficiency and scope of application of ultrasonic extraction technology can be improved through further research and technological innovation, so as to provide strong support for the development of the cosmetics industry.
