Oleuropein(CAS: 32619-42-4)

Oleuropein (CAS: 32619-42-4) is a natural secoiridoid glycoside polyphenol compound extracted and purified from olive leaves and fruits. It is the core and representative active ingredient of olive plants. As a high-activity water-soluble plant polyphenol, Oleuropein has a stable molecular structure and diverse biological activities. Different from ordinary plant active ingredients, it has excellent water solubility and high biocompatibility. With natural and safe characteristics, it has been widely used in high-end cosmetics, functional foods, health supplements and biomedical research industries, and has become one of the most popular natural antioxidant raw materials in the global plant extract market.

In terms of physical and chemical properties, Oleuropein is white to pale yellow crystalline powder with no peculiar smell and slight bitter taste. It has stable physical and chemical properties. The most prominent advantage is excellent water solubility, which can be quickly dissolved in pure water and warm water, and also soluble in ethanol. It is compatible with most water-based and alcohol-based industrial formulas. The product has good high temperature resistance and acid-base stability. However, polyphenol ingredients are sensitive to strong light and high humidity. Long-term light exposure and damp environment will cause color darkening and activity loss. It must be stored in sealed, light-proof, cool and dry conditions to ensure stable purity and activity, meeting food-grade, cosmetic-grade and research-grade raw material standards.

In industrial production, high-quality fresh olive leaves and fruits are selected as raw materials. Oleuropein is produced through low-temperature water extraction, multi-stage resin enrichment and refining process. The production procedures include raw material screening, cleaning, low-temperature drying, crushing, constant temperature water extraction, vacuum concentration, impurity removal, macroporous resin enrichment, decolorization, sterilization and vacuum drying. Adopting pure physical low-temperature extraction technology, the process completely retains the natural active structure of secoiridoid glycosides without harmful chemical residues. Invalid impurities such as crude fiber, pectin and pigment are strictly removed to improve product purity. The finished powder is uniform, low in impurities and stable in quality, suitable for mass industrial production and high-end formula customization.

Oleuropein has mild and efficient biological activities, mainly including anti-oxidation, anti-inflammation, antibacterial and skin repair. It has strong free radical scavenging ability, which can effectively eliminate excess free radicals, inhibit lipid peroxidation and delay cell aging. It can significantly inhibit the release of inflammatory factors, relieve skin redness and dryness, and inhibit harmful bacteria. In skin care, it repairs skin barrier, locks moisture and improves dull and rough skin. For body care, it regulates metabolism, enhances antioxidant capacity and maintains physical balance. With high safety and mild effect, it is suitable for long-term application.

Oleuropein covers a wide range of high-end application fields. In the cosmetic industry, it is a core raw material for anti-aging, soothing and repairing skincare products. In health products and functional food industry, it is used for antioxidant and body conditioning supplements. In the pharmaceutical field, it serves as an intermediate for anti-inflammatory and antioxidant drug research. In scientific research, it is widely used as a standard reference substance for polyphenol component analysis and pharmacological experiments.

With the popularization of natural skincare and healthy living concepts, high-activity and mild plant raw materials are increasingly favored by the market. Benefiting from natural origin, high safety, excellent water solubility and comprehensive efficacy, Oleuropein maintains growing market demand. In the future, with the continuous optimization of purification technology, product purity and stability will be further improved. With mature production technology and diverse biological activities, Oleuropein will continue to develop in the fields of cosmetics, health products and biomedicine, possessing broad market development prospects.
