How we scored it
Where it comes from
Centella Asiatica Extract is produced by aqueous or hydroalcoholic extraction of the whole Centella asiatica plant. No petrochemical production route exists; only the extraction solvent varies by supplier.
The production of Centella Asiatica Extract is primarily an extraction process, not a synthesis in the chemical sense. The process begins with the harvesting and drying of the Centella Asiatica plant material. This dried material is then typically subjected to solvent extraction to isolate the desired active compounds. Common solvents used include water, ethanol, or mixtures of ethanol and water, chosen based on the polarity of the target phytochemicals such as asiaticosides, madecassosides, asiatic acid, and madecassic acid.
The extraction is often performed using methods like maceration, percolation, or more advanced techniques such as ultrasound-assisted extraction (UAE) or microwave-assisted extraction (MAE) to improve efficiency and reduce extraction time. Following the initial extraction, the solvent is removed, usually through evaporation under reduced pressure (e.g., using a rotary evaporator) to yield a concentrated extract.
Further purification steps may be employed depending on the desired grade and application of the extract. These can include filtration to remove particulate matter, chromatography to isolate specific compounds, or precipitation techniques. The final product is typically a powder or a viscous liquid, standardized to contain specific percentages of key active ingredients like asiaticosides, which are crucial for its efficacy in cosmetic applications.
In plain English
Centella Asiatica Extract, often called 'Gotu Kola' or 'Tiger Grass,' comes from a small, green plant that grows in tropical wetlands. For centuries, this plant has been used in traditional medicine for its healing properties. In cosmetics, it's prized for its ability to soothe and repair the skin.
When used in skincare products, the extract is carefully obtained from the plant's leaves and stems. This is done by using safe solvents, like water or alcohol, to draw out the beneficial compounds. These compounds, such as madecassoside and asiaticoside, are powerful antioxidants and anti-inflammatories. They help calm irritated skin, reduce redness, and support the skin's natural healing process, making it a popular ingredient for sensitive or damaged skin.
CosIng definition: Centella Asiatica Extract is the extract of the whole plant Hydrocotyl, Centella asiatica L., Apiaceae
