Thioctic Acid
What is Thioctic Acid?
Thioctic acid, chemically known as alpha-lipoic acid, is a naturally occurring organosulfur compound produced in small amounts by the human body and found in certain foods like spinach and organ meats. It features a distinctive five-membered ring structure with a disulfide bond, making it uniquely both water- and fat-soluble. This dual solubility allows it to function effectively across various phases in cosmetic formulations. Primarily categorized as an antioxidant agent, it neutralizes free radicals in products, preventing degradation of oils and other sensitive components, which helps maintain efficacy and extend shelf life. In skincare applications, it contributes to formulation stability and may support skin's defense against environmental oxidative factors.
