PENTAERYTHRITYL TETRAMERCAPTOBUTYRATE

Description

Pentaerythrityl Tetramercaptobutyrate is a synthetic antioxidant and chelating agent used in skincare and haircare formulations. This multifunctional ingredient serves as a stabilizer and preservative enhancer, prolonging the shelf life of products by preventing oxidation and degradation of sensitive components.

The compound's structure consists of a pentaerythritol core with four mercaptobutyrate groups attached. This unique configuration allows it to effectively scavenge free radicals and chelate metal ions, which are common catalysts for oxidative reactions in cosmetic formulations.

In skincare, Pentaerythrityl Tetramercaptobutyrate helps maintain the efficacy of active ingredients, particularly those prone to oxidation, such as vitamin C and retinol. It also contributes to the overall stability of emulsions and oil-based products.

For haircare applications, this ingredient aids in preserving the integrity of hair dyes and color treatments by inhibiting oxidation processes that can lead to color fading. Additionally, it helps protect hair proteins from damage caused by environmental stressors and chemical treatments.

Typically used in concentrations ranging from 0.01% to 0.1%, Pentaerythrityl Tetramercaptobutyrate is generally considered safe for cosmetic use when formulated properly.
