Description

Grape Seed Oil is a premium, cold-pressed vegetable oil derived from the seeds of Vitis vinifera grapes. This natural oil is valued for its high concentration of polyunsaturated fatty acids, particularly linoleic acid, and its content of beneficial antioxidants like proanthocyanidins and vitamin E. It serves as a versatile and functional ingredient for manufacturers in the cosmetics, nutraceutical, and food industries seeking natural, skin-compatible, and health-promoting lipid components.

Application

• Dietary Supplements & Nutraceuticals: Used in softgel capsules and liquid formulations for its potential cardiovascular and antioxidant health benefits.
• Functional Food & Beverage: Incorporated as a healthful lipid source in specialty foods, dressings, and nutritional beverages.
• Pharmaceutical & Topical Preparations: Employed as a base or excipient in ointments, creams, and transdermal delivery systems.
• Aromatherapy & Carrier Oils: Serves as an ideal, light-textured carrier oil for diluting essential oils.
• Industrial Applications: Potential use in natural lubricants, wood finishes, or as a raw material for oleochemical derivatives.
