DIMYRISTYL THIODIPROPIONATE

Description

Dimyristyl Thiodipropionate (DMTDP) is a multifunctional cosmetic ingredient that serves primarily as an antioxidant in skincare formulations. This synthetic compound consists of two myristyl chains attached to a thiodipropionate core, providing it with unique properties that benefit various skincare products.

DMTDP acts as a powerful antioxidant, protecting formulations and skin from oxidative stress caused by free radicals and environmental factors. Its lipophilic nature allows it to integrate seamlessly into oil-based products, enhancing their stability and shelf life. This ingredient is particularly effective in preventing the oxidation of other ingredients, especially unsaturated oils and fats, which are prone to rancidity.

In skincare applications, DMTDP can help maintain the efficacy of active ingredients by preventing their degradation due to oxidation. It also contributes to the overall preservation of product integrity, reducing the need for additional preservatives. DMTDP is generally well-tolerated by most skin types and is often used in concentrations ranging from 0.1% to 1% in formulations.

While DMTDP is primarily valued for its antioxidant properties, it may also offer mild emollient effects, contributing to smoother and softer skin texture in some formulations.
