What is thiodipropionic acid?
Thiodipropionic acid is a dicarboxylic acid containing a sulfur group. It is used as an antioxidant to prevent or slow down the deterioration of ingredients due to chemical reactions with oxygen.
in cosmetics and food. Dilauryl thiodipropionate, hexadecyl thiodipropionate, dimyristyl thiodipropionate, distearyl thiodipropionate and distridedecyl thiodipropionate are Diester derivatives of thiodipropionic acid with similar functions. This means that each oxygen atom of the carboxyl group has a carbon chain attached to it (chain length is 12 to 18 carbons). Of these ingredients, thiodipropionate and dilauryl thiodipropionate are most commonly found in cosmetics and personal care products, including eye and face makeup products and skin care preparations.
Why use it?
Thiodipropionic acid and its derivatives can prevent or slow down the deterioration of cosmetics and personal care products by inhibiting the reaction that occurs on contact with oxygen in the air.
Thiodipropionic acid uses in food
Thiodipropionic acid is an antioxidant used to prevent fats and oils from going rancid. Thiodipropionic acid has the same functions as bha, bht and propyl gallate. - Thiodipropionic acid is used as an antioxidant in fats and other foods.
Safety information
The U.S. Food and Drug Administration (FDA) includes thiodipropionic acid, dilauryl thiodipropionate, and distearyl thiodipropionate on its list of antioxidants that can be used in food packaging materials. Thiodipropionic acid and dilauryl thiodipropionate are also on the list of substances generally recognized as safe (GRAS) is an abbreviation of "Generally Recognized As Safe". According to the Federal Food, Drug, and Cosmetic Act (hereinafter referred to as the "Act") Sections 201(s) and 409, any substance intentionally added to food is a food additive and is subject to premarket review and approval by the FDA, unless the substance is generally considered to be sufficiently proven by qualified experts Safe under the conditions of its intended use or unless the use of the substance is excluded from the definition of food additive.) as a chemical preservative for use in food. Thiodipropionic acid, dilauryl thiodipropionate, hexadecyl thiodipropionate, dimyristyl thiodipropionate, distearyl thiodipropionate and thiodipropionic acid The safety of distridecyl thiodipropionate has been evaluated with respect to the safety of distridecyl thiodipropionate. Cosmetic Ingredient Review Cosmetic Ingredient Review (CIR) was established in 1976 as an independent safety review program for cosmetic ingredients. The CIR Expert Panel consists of independent experts in the fields of dermatology, toxicology, pharmacology and veterinary medicine. The CIR includes the involvement of the U.S. Food and Drug Administration. Drug Administration and Consumers Union. (CIR) Panel of Experts. A CIR expert panel evaluated the scientific data and concluded that these six ingredients are safe for use in cosmetics and personal care products when formulated to be non-irritating.
CIR Security Review
Laboratory test data shows that dilauryl thiodipropionate does not have any effects at dietary concentrations of up to 3%. Thiodipropionic acid is not genotoxic and is not a developmental poison. Skin studies show that thiodipropionic acid and dilauryl thiodipropionate are not sensitizers or phototoxic agents.
Although some formulations containing dilauryl thiodipropionate were irritating to some subjects, other formulations containing dilauryl thiodipropionate were not irritating to any of the subjects tested. Therefore, the CIR Panel concluded that thiodipropionic acid, dilauryl thiodipropionate, hexadecyl thiodipropionate, dimyristyl thiodipropionate, dilauryl thiodipropionate The ingredients stearyl and tridecylthiodipropionate are safe for use in cosmetics and personal care products when formulated to be non-irritating.
According to regulations, thiodipropionic acid, dilauryl thiodipropionate, hexadecyl thiodipropionate, dimyristyl thiodipropionate, distearyl thiodipropionate and thiodipropionate Tricosanyl dipropionate is used in cosmetics and personal care products sold in Europe.
