## Abstract

An antimicrobial eyelid cleanser composition contains: (a) a hypohalous acid; (b) one or more surfactants having a HLB value of 5 to 18; and (c) an aqueous vehicle, the aqueous vehicle comprising: (i) one or more tonicity adjusters; (ii) one or more osmolality adjusters for adjusting an osmolality of the composition; and (iii) one or more pH adjusters for maintaining the pH of the composition at between about 4.5 to about 8.0. The composition can be dispensed in a foam, liquid, spray, mist, gel or lotion form. The composition can facilitate long term eyelid hygiene by removing excess oil, debris and desquamated skin and provide relief for inflammation of the eyes.
