Abstract
A smooth, greaseless skin ointment especially prepared for irritated skin, which protects, adheres and simultaneously is easily washable without causing skin damage. The ointment base is a blend of polyethylene glycols. It is combined with a bioadhesive which works synergistically to allow the blended ointment base to adhere to wet and moist areas, while not being so adhesive as to cause damage when removed in washing. Specifically a blend of polyethylene glycol polymers is prepared to provide good skin feel and drag, a polyvinyl ether anhydride salt bioadhesive is added and a polyvinylpyrrolidone is also used as a dispersant, and feces and urine toxicant binder. Optionally minor amounts of dimethicone can be added.
