DITRIDECYL THIODIPROPIONATE.

Valuable CAS 10595-72-9 / ANTIOXIDANT

Ditridecyl Thiodipropionate is a synthetic ingredient primarily functioning as an antioxidant and stabilizer in cosmetic formulations. It extends product shelf-life by preventing oxidative degradation, thereby preserving the color and texture of skincare preparations. This compound also exhibits excellent thermal stability, guarding against heat and light-induced deterioration.

Summary

Antioxidant Stabilizer

Science

Mechanism of Action

This ingredient operates primarily as an antioxidant and stabilizer within cosmetic formulations, inhibiting oxidation reactions caused by oxygen, heat, and light. This action is crucial for preventing the degradation of a product's color, texture, and overall integrity. While its direct benefits on skin are not extensively detailed for this specific compound, related thiodipropionates are known to offer protection against free radicals and UV damage, and some act as emollients, enhancing skin texture and moisture retention.

Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel concluded that Ditridecyl Thiodipropionate is safe for use in cosmetic and personal care products when formulated to be non-irritating. A maximum concentration of 0.05% for dermal application is recommended, based on safety data extrapolated from Dilauryl Thiodipropionate. While formulations with related compounds at up to 4% have shown irritation in some subjects, studies at 0.05% indicated no irritant, sensitizing, or phototoxic effects. Related thiodipropionates are also recognized by the FDA as Generally Recognized As Safe (GRAS) chemical preservatives and antioxidants in food applications.
