3,4-Dichlorobenzyl alcohol is widely used as a preservative and antiseptic in various personal care, cosmetic, and pharmaceutical products. Its antimicrobial properties help prevent the growth of bacteria, fungi, and other microorganisms, ensuring the safety and longevity of these products. It is commonly found in oral care items like mouthwashes and throat lozenges, shampoos, conditioners, lotions, and other skincare products. Additionally, it is utilized in pharmaceutical formulations, including topical preparations, to maintain sterility, prevent infections, and extend shelf life. Its effectiveness at low concentrations makes it a preferred choice in formulations where minimal preservative impact is desired.
