P-CHLOROPHENOL

Description

P-Chlorophenol, also known as 4-chlorophenol, is a synthetic organic compound with the chemical formula C6H5ClO. It is a chlorinated derivative of phenol, appearing as colorless to pale yellow crystals with a characteristic phenolic odor. This compound has been utilized in various skincare and cosmetic formulations due to its antimicrobial and preservative properties.

In skincare, p-chlorophenol functions primarily as a preservative, helping to extend the shelf life of products by inhibiting the growth of bacteria and fungi. Its effectiveness against a broad spectrum of microorganisms makes it valuable in maintaining product integrity and safety. However, its use has become increasingly limited due to concerns about potential skin irritation and environmental impact.

P-chlorophenol exhibits moderate solubility in water and high solubility in organic solvents, influencing its formulation capabilities. Its molecular structure allows for penetration through the stratum corneum, potentially enhancing the preservative effect within products. While effective at low concentrations, regulatory bodies have established strict guidelines for its use in cosmetics due to its potential for skin sensitization and ecological concerns. Alternative preservatives are often preferred in modern formulations to address these issues while maintaining product stability and safety.
