Tocopheryl Linoleate
What is Tocopheryl Linoleate?
Tocopheryl Linoleate is a synthetic ester derived from tocopherol, a natural form of vitamin E sourced from vegetable oils, and linoleic acid, an omega-6 polyunsaturated fatty acid found in seeds like sunflower and safflower. This combination creates a lipid-soluble compound with improved oxidative stability over free tocopherol, making it ideal for incorporation into oil-based and emulsion cosmetic products such as moisturizers, serums, and night creams. In formulations, it primarily functions by donating hydrogen atoms to neutralize reactive oxygen species, thereby preventing lipid peroxidation and extending product shelf life. It also acts as an emollient, enhancing skin suppleness by mimicking natural sebum components, and contributes to a lightweight film that shields the skin barrier from moisture loss and external pollutants without clogging pores.
