Nasturtium Officinale Leaf/Stem Extract is derived from the leaves and stems of the watercress plant, scientifically known as Nasturtium officinale, which belongs to the Brassicaceae family. This ingredient is also commonly referred to as watercress extract. Watercress is a leafy green aquatic plant that has been used for centuries, not only as a nutritious food but also for its medicinal properties.
Historically, watercress has been valued for its high content of vitamins and minerals, particularly vitamin C, vitamin K, and various antioxidants. Its use in cosmetics, however, is a more recent development. The extract has gained popularity in skincare formulations due to its skin conditioning properties, which help to maintain the skin’s appearance and texture.
The process of making Nasturtium Officinale Leaf/Stem Extract typically involves harvesting the leaves and stems of the watercress plant, followed by a series of extraction methods. These methods can include solvent extraction, where the plant material is soaked in a solvent to draw out the beneficial compounds, or cold pressing, which involves mechanically pressing the plant material to extract the juices. The resulting extract is then filtered and purified to ensure it is suitable for use in cosmetic products.
