2-TERT-BUTYL-P-CRESOL

Description

2-Tert-butyl-p-cresol, also known as butylated hydroxytoluene (BHT), is a synthetic antioxidant widely used in skincare and cosmetic formulations. This phenolic compound is prized for its ability to prevent oxidation and extend the shelf life of products. BHT functions by neutralizing free radicals, which can cause degradation of other ingredients and lead to product instability.

In skincare applications, 2-tert-butyl-p-cresol is typically used in concentrations ranging from 0.01% to 0.1%. It helps maintain the efficacy of active ingredients, particularly those susceptible to oxidation, such as vitamins and oils. This preservative action ensures that products remain stable and effective throughout their intended use period.

While primarily utilized for its antioxidant properties, some studies suggest that BHT may also have mild anti-inflammatory effects on the skin. However, its primary role remains as a preservative and stabilizer in formulations.

It's important to note that 2-tert-butyl-p-cresol is fat-soluble and can penetrate the skin barrier. As with any ingredient, patch testing is recommended, especially for individuals with sensitive skin or known allergies to similar compounds.
