dilauryl thiodipropionate ●
TL;DR. It functions primarily as an antioxidant and formula stabilizer, slowing oxidation of oils, waxes, fragrances, and other oxidation-prone lipids. It helps protect color, odor, and rancidity profile rather than providing a direct skin benefit.
What does dilauryl thiodipropionate do in a cosmetic formula?
It functions primarily as an antioxidant and formula stabilizer, slowing oxidation of oils, waxes, fragrances, and other oxidation-prone lipids. It helps protect color, odor, and rancidity profile rather than providing a direct skin benefit.
Is dilauryl thiodipropionate clean?
From a clean beauty perspective, this is a synthetic stabilizer with limited consumer-facing use, but it is not a common allergen or a headline restricted-list ingredient. The main friction is its industrial-antioxidant profile, low data visibility in cosmetics, and very high lipophilicity.
Is dilauryl thiodipropionate sustainable?
It is typically made by esterifying a sulfur-containing acid intermediate with fatty alcohols that may come from palm kernel, coconut, or petrochemical routes. Its very low water solubility and high lipophilicity make environmental behavior less straightforward, even though ester bonds can support breakdown over time.
Is dilauryl thiodipropionate COSMOS-approved?
It is not generally permitted under COSMOS organic or COSMOS natural standards because it is a synthetic antioxidant outside the standard’s accepted natural-origin chemistry. Its Green Chemistry fit is limited by synthetic feedstock dependence and uncertain environmental fate compared with readily biodegradable plant-derived antioxidants.
How does dilauryl thiodipropionate work chemically?
The molecule is a high-molecular-weight thioether diester with two C12 fatty chains, which makes it oil-soluble and suited to lipid phases rather than water-based systems. It is used at low stabilizing levels, commonly around 0.01% to 0.5%, and often pairs with primary antioxidants because sulfur-containing secondary antioxidants help decompose hydroperoxides formed during lipid oxidation.
