COMPOSITION CONTAINING C8F17Br AND METHOD FOR PRODUCING C8F17Br
-
Paragraph 0054-0057, (2020/06/08)
This invention provides a composition that contains PFOB with a PFOA content lower than that of known PFOB, and that is less likely to have an adverse effect on the environment; and provides a method for producing PFOB. The composition contains C8F17Brand further contains C7F15COOH, wherein C7F15COOH is present in a concentration of 25 ppb or less based on the total weight of C8F17Br. The method for producing C8F17Br comprises reacting C8F17I and a brominating agent to obtain C8F17Br, and alkali-washing the obtained C8F17Br to reduce the C7F15COOH content to 25 ppb or less based on the total weight of C8F17Br.

, (2008/06/13)
Compositions for topical application in gel form comprising a fluorocarbon or perfluorocarbon compound or mixtures thereof at a concentration of at least about 75% v/v, a minor quantity of a surface active agent and an aqueous phase. The compositions provide a storage-stable high concentration fluorocarbon gel that is prepared without the use of thickeners or additional stabilizing agents. The gels are useful in formulations for pharmaceutical, cosmetic purposes and for other products as well.
