Abstract
Abstract A composition and method for the effective, nonirritating treatment of acne is disclosed. The method includes treatment of the affected area by topical application of an ozonized material derived by ozonizing various fixed oils and unsaturated esters, alcohols, ethers and fatty acids. The ozonized materials of the present invention have the ability to penetrate the comedone and deliver nascent oxygen directly to the acne microorganisms without the characteristic dryness and skin irritation associated with previous methods of acne treatment.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
103 words
A method for treating acne which comprises applying topically to an affected area an effective amount of an ozonide of fixed oils, esters, fatty acids, alcohols and ethers containing an olefin of the general formula; ##STR4## wherein: R 3 and/or R 4 may by hydrogen or: ##STR5## where R 5 =(CH 2 ) n -CH 3 and n=an integer from 0 to 12; with R 1 and R 2 being any value given for R 3 and R 4 with the proviso that R 1 and R 2 cannot both equal H and also R 3 and R 4 cannot both equal H.
Claim 2
Independent Claim
103 words
A method for treating acne which comprises applying topically to an affected area an effective amount of an ozonide of fixed oils, esters, fatty acids, alcohols and ethers containing an olefin of the general formula; ##STR4## wherein: R 3 and/or R 4 may by hydrogen or: ##STR5## where R 5 =(CH 2 ) n -CH 3 and n=an integer from 0 to 12; with R 1 and R 2 being any value given for R 3 and R 4 with the proviso that R 1 and R 2 cannot both equal H and also R 3 and R 4 cannot both equal H.
