Abstract
Abstract A composition and treatment to prevent the symptoms of skin conditions characterized by an offensive odor of the body, such as diaper rash, perspiration odor and athlete's foot. The composition contains as the active ingredient a non-toxic, high molecular weight organic polymeric acid which is not absorbed through the skin. Treatment is by topical application of a dusting powder, aerosol spray, cream or ointment containing 1 to 30% by weight of a high molecular weight organic polymeric acid such as alignic acids, Carbopol resins or other polymeric acids.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
96 words
A method for the treatment and prevention of symptoms of conditions characterized by offensive odor of the body which comprises topically applying to the regions of the body subject to offensive odor a composition comprising: (a) from 1 to 30% by weight of a non-toxic, high molecular weight alginic acid, having a molecular weight in the range of from 15,000 to 900,000; and (b) from 70 to 99% by weight of a pharmaceutical carrier said alginic acid being applied to said body region in an amount effective to arrest or prevent the development of offensive odor.
Claim 2
Independent Claim
