It is effective against a range of microorganisms, making it suitable for use in mouthwashes, throat lozenges, and skin antiseptics. Its surfactant properties also make it useful in formulations requiring emulsification or solubilization, such as in some pharmaceutical and cosmetic preparations. Additionally, it can be employed as a phase transfer catalyst in organic synthesis.
