2,2'-THIOBIS(4-CHLOROPHENOL)

Description

2,2'-Thiobis(4-chlorophenol) is a synthetic organic compound with antimicrobial properties, commonly used in personal care and cosmetic products. This ingredient consists of two 4-chlorophenol molecules linked by a sulfur atom, resulting in a structure that effectively combats various microorganisms.

The compound exhibits broad-spectrum antimicrobial activity against bacteria, fungi, and yeasts, making it valuable in preservative systems for skincare formulations. Its efficacy is particularly notable in products with high water content, where microbial growth is more likely to occur. 2,2'-Thiobis(4-chlorophenol) works by disrupting the cellular membranes of microorganisms, leading to their death and preventing product contamination.

In skincare applications, this ingredient is typically used in concentrations ranging from 0.1% to 0.3%, depending on the formulation and regulatory guidelines. It is often combined with other preservatives to create synergistic effects and enhance overall product stability.

While effective, 2,2'-Thiobis(4-chlorophenol) may cause skin sensitization in some individuals. Formulators must carefully consider its concentration and potential interactions with other ingredients to ensure product safety and efficacy. Regulatory bodies, including the FDA and EU Commission, have established guidelines for its use in cosmetic products.
