Dilauryl thiodipropionate

Описание

Dilauryl thiodipropionate (DLTDP) is a part synthetic, part plant-derived ester blend made from the fatty alcohol lauryl alcohol and the antioxidant thiodipropionic acid. Not surprisingly, it has antioxidant benefits on the skin and, according to older research from Avon, may play a role in fading the appearance of discolourations. It also works in cosmetics as a sequestering agent, which helps keep ingredients in a formula from having unwanted interactions. As such, it also helps stabilize cosmetics. DLTDP is a secondary artificial antioxidant widely used to extend the shelf life of products in the food, cosmetic, and polymer industries. Furthermore, some studies on asphalt antioxidants warned about the softening effect of DLTDP on asphalt binders, even after ageing. DLTDP has been declared by the U.S. Food and Drug Administration (FDA) as generally recognized as safe (GRAS) for use in food and cosmetics, which implies its safe use when used as intended and under specific limitations (based mainly on fat content)[1].

Использование

Dilauryl Thiodipropionate (DLTDP) is an antioxidant that exists as white crystalline flakes of sweetish ester-like odor. It is insoluble in water but soluble in inorganic solvents. It is used in fats and oils to prevent rancidity. It is used in food when the total antioxidant content is not over 0.02% of the fat or oil content.

Профиль безопасности

An eye irritant. When heated to decomposition it emits toxic fumes of SOx. Thiodipropionic Acid and Dilauryl Thiodipropionate are also on the list of substances that are Generally Recognized As Safe (GRAS ) as chemical preservatives for use in foods.
