DILAURYL THIODIPROPIONATE
DILAURYL THIODIPROPIONATE is a dialkyl ester made from thiodipropionic acid and dodecyl groups. It is not a botanical extract or a laurel oil: in this name, lauryl refers to the long alkyl chains that are part of the substance's chemical structure.
DILAURYL THIODIPROPIONATE: what it is
DILAURYL THIODIPROPIONATE is a dialkyl ester made from thiodipropionic acid and dodecyl groups. It is not a botanical extract or a laurel oil: in this name, lauryl refers to the long alkyl chains that are part of the substance's chemical structure.
It belongs to a family of thiodipropionic-acid esters distinguished by the length of the chains attached to the ester. That detail helps explain why it can appear in a small amount in a formula as a stability component, rather than as the oil or headline active someone might expect from a product label.
DILAURYL THIODIPROPIONATE: what it does in cosmetics
In cosmetics, DILAURYL THIODIPROPIONATE works as an antioxidant for the formula. In practical terms, it helps limit oxidation-related changes in sensitive components over the product's shelf life, supporting the intended appearance and use of the composition. This does not mean it acts as a skin antioxidant.
The safety assessment covering this ingredient and related esters examined toxicology and irritation rather than cosmetic treatment outcomes. It does not support claims for acne, dark spots, wrinkles, or other skin conditions; its plausible role here is helping preserve the formula, not providing a stand-alone care effect to the user.
DILAURYL THIODIPROPIONATE: conditions and care
The CIR safety conclusion is conditional on use in formulations that are non-irritating. Clinical testing found some evidence of irritation, without sensitization or photosensitization.
