Grapeseed oil is extracted from the seeds of grapes, typically wine grapes. Since grape seeds are usually discarded as part of the wine making process, the extraction and sale of grapeseed oil is an efficient use of a byproduct. Because each seed yields a small amount of oil, grapeseed oil is usually extracted chemically. The chemical extraction does have an impact on the flavor of the oil, but it makes grapeseed oil affordable for people who want to purchase it. The oil is known for being light in color and flavor, with a hint of nuttiness. It is a polyunsaturated oil, and contains beneficial compounds such as linoleic acid. There are two primary uses for grapeseed oil: cosmetics and culinary applications. Some cosmetic grapeseed oils are stabilized with chemicals. Like other oils, grapeseed oil should be stored in a cool dark place until it is used, unless it has been heavily stabilized. In cosmetics, grapeseed oil is widely used. It is often combined with other oils to make massage oil, since it glides well on the skin and it also has moisturizing properties. Grapeseed oil appears to assist with skin repair, as it has mildly astringent and antiseptic qualities. Some companies use grapeseed oil as a short term natural preservative in body products, while others integrate it into moisturizing creams, sunscreen, and an assortment of other products.
