This invention relates to a non-irritating liquid composition useful in cleansing the eyelids.
Blepharitis is a common chronic inflammation of the eyelids characterized by a scaly crust on the lid margins The condition may be caused by a bacterial infection, or it may be allergic in origin or associated with seborrhea of the face and scalp. Treatment usually involves cleansing the eyelids on a regular basis.
Often associated with or secondary to blepharitis is a bacterial infection of the surface of the skin at the edge of the lid know as an external hordeolum or of the meibomian glands, either, commonly referred to as sties. Such conditions also are accompanied by pain, redness and tenderness of the lid margins. Although sties are often recurring, such conditions can be minimized by regular cleansing of the eyelid margins.
The following table describes the preferred concentration of ingredients for the cleansing solution of the instant invention:
