Dilauryl Thiodipropionate
What is Dilauryl Thiodipropionate?
Dilauryl thiodipropionate is a synthetic thioester compound formed by esterifying thiodipropionic acid with lauryl alcohol, resulting in a lipophilic molecule suited for oil phases. This ingredient falls under the category of indirect antioxidants in cosmetics, commonly added to anhydrous products like balms, oils, and emulsions. It functions by scavenging free radicals and interrupting peroxide formation during lipid peroxidation, which helps preserve the structural integrity of unsaturated fatty acids and volatile components. In formulations, it extends shelf life by minimizing degradation that leads to rancidity, discoloration, or potency loss of sensitive materials. Its non-volatile nature ensures it remains effective without evaporating, making it ideal for long-lasting products such as hair treatments and protective creams exposed to air and light.
Roles in Formulation
This ingredient serves the following purposes in cosmetic formulations:
Benefits
Stabilizes oils and emollients against oxidative breakdown for fresher products.
Prevents formation of off-odors and color shifts in oil-rich formulas.
Enhances overall product shelf life without affecting texture.
