Our Green Tea Liquid Extract is a liquid blend of Green Tea Extract and Propanediol. This Liquid Green Tea Extract is standardized to possess 17.6% Polyphenols, also known as catechins, which are the active constituents in Green Tea. These catechins are antioxidants which are said to have many benefits including helping to cool irritated skin, alleviate damage caused by skin dryness, improve skin elasticity and help cleanse the skin by helping remove dirt, bacteria, and other pollutants from the skin surface. Propanediol is a plant based, biodegradable and petrochemical-free solvent that is becoming more and more popular as it is a corn sugar-derived alternative to petroleum-based Glycols in personal care formulations. This Green Tea Liquid Extract makes a great addition to a variety of personal care products including creams, lotions, hair care products, anti-aging products and more!
