Quercus Glauca Seed Extract is derived from the seeds of the Quercus glauca tree, which belongs to the Fagaceae family. Also known as the Japanese Blue Oak, this tree is native to East Asia, particularly Japan, China, and Korea. The extract is sometimes referred to by other names such as Blue Japanese Oak Seed Extract or simply Japanese Oak Seed Extract.
The seeds of Quercus glauca are rich in various bioactive compounds, including tannins, flavonoids, and phenolic acids. These compounds are known for their antioxidant properties, which can help protect the skin from environmental stressors and free radical damage.
Historically, the Quercus glauca tree has been valued for its wood and acorns, which have been used in traditional medicine and as a food source. However, its seeds have recently gained attention in the cosmetic industry for their potential skin-conditioning benefits. The journey of Quercus glauca Seed Extract into cosmetics began with scientific research highlighting its antioxidant and skin-soothing properties, making it a desirable ingredient for skincare formulations.
The extraction process typically involves harvesting the seeds, followed by drying and grinding them into a fine powder. This powder is then subjected to a solvent extraction process, usually involving water or alcohol, to isolate the beneficial compounds. The resulting extract is filtered and purified to ensure it is safe and effective for use in cosmetic products.
