Description

2,4-Dichlorobenzyl alcohol (CAS 1777-82-8 ), also known commercially as Dybenal, is an aromatic chlorinated alcohol used primarily as an antimicrobial and preservative agent across industrial and consumer product sectors. It delivers broad-spectrum activity against bacteria and fungi, making it a functional ingredient where microbial control is a formulation requirement in various manufacturing processes. In pharmaceutical and healthcare products, it is a recognized active ingredient in throat lozenges and topical antiseptic formulations, where it provides localized antimicrobial action for patients. Personal care and cosmetic manufacturers incorporate it as a preservative booster in rinse-off and leave-on products requiring protection against microbial contamination during their shelf life. Industrial applications include its use as a biocide in textile processing and leather treatment, where it controls microbial degradation during critical wet processing stages in the factory. Its chlorinated aromatic structure also supports flame retardant applications in construction materials and polymer systems, providing essential safety characteristics to the final industrial products. The material is supplied as a white to off-white crystalline powder or solid. It is available in pharmaceutical-grade specifications, including BP and Ph. Eur. compliance for regulated uses. Technical-grade material is also available for industrial biocide and flame retardant end uses, ensuring that manufacturers have the appropriate quality for their specific application needs.
