Product Name: Rosemary extract

Latin Name: Rosmarinus officinalis

Raw material: Rosmarinic acid in rosemary is a polyphenol hydroxyl acid, first isolated from the rosemary plant in 1958. Romarinic acid is widely distributed, from lower mosses to higher dicotyledonous plants, mainly in labiaceae, Amaranthaceae, cucurbitaceae, linden tree, umbelliferae.

Active Ingredient: Rosmarinic acid in rosemary

CAS No.: 20283-92-5

Chemical formula: C18H16O8

Extraction method of rosmarinic acid in Rosemary:

1. Solvent extraction: Solvent extraction is a method to extract the effective ingredients of medicinal materials by soaking them in appropriate solvents at room temperature or under warm conditions for a certain time. This method is easy to operate, simple and easy.

2. The most common extraction method of rosmarinic acid in Rosemary is ultrasonic extraction. Ultrasonic extraction a method of extracting active ingredients by ultrasonic extraction. The principle is to use the cavitation effect of ultrasonic wave to destroy the medicinal material cells, so that the solvent is easy to infiltrate into the cells, while the strong vibration of ultrasonic wave can transfer huge energy to extract medicinal materials and solvent, so that it makes high-speed movement, strengthen the release, diffusion and dissolution of substances in the cell, accelerate the leaching of effective components.

3. Supercritical fluid extraction : supercritical fluid extraction is a new technology for the extraction and separation of the active components in plants by using the fluid formed by a substance in the supercritical region. Supercritical fluid refers to when a material is above the critical temperature and critical pressure, forming a neither liquid nor the special status of the gas, in this state, liquid fluid have the characteristics of two phase, both close to gas concentration, and close to liquid density, to have a strong ability to dissolve many substance, can be used as extraction solvent

4. Enzymatic extraction: In addition, several enzymatic methods have been applied to the extraction process of rosmarinic acid in Rosemary. Enzymatic extraction is a new technology to extract effective components from plants by using appropriate enzymes and decomposing plant tissues by enzymatic reaction. Its advantages are high reaction specificity, rapid, efficient, mild reaction conditions and easy to control, especially suitable for the extraction of active ingredients which are very low and subject to the influence of solvents and prone to structural changes.

Application on Cosmetics:

In most people's minds, most antioxidants in skin care products are vitamins E and C, along with selenium from the plant, but it never occurred to them that rosemary extract is also a powerful natural antioxidant. Rosmarinic acid in Rosemary is an important component in rosemary extract. It has strong antioxidant activity, its antioxidant activity is stronger than vitamin E, caffeic acid, chlorogenic acid, folic acid and so on. It can effectively remove the active oxygen in environmental pollution, inhibit the formation of melanin, with excellent whitening and moisturizing effect.

Rosmarinic acid in Rosemary also has strong anti-inflammatory activity, protecting and strengthening the skin, improving blood circulation and improving skin function. Meanwhile, romarinic acid in Rosemary has antibacterial and antiviral functions that can inhibit acute and chronic infections, and is resistant to ultraviolet rays and can inhibit the degradation of elastin. These all make it an excellent natural additive for skin care products. At present, rosmarinic acid in Rosemary has shown its important application value in skin care products.

To prevent contamination, most skin care products contain preservatives. Preservatives are unsafe ingredients that can cause skin irritation, inflammation and other skin problems. The application of rosemary extract in skin care products solves these problems. Natural antioxidants - Rosemary extract is added to skin care products to extend the life of the product, while replacing artificial antioxidants and reducing the amount of preservatives in formulations.
