Hair care compositions and methods of treating hair
View Patent ↗The present invention provides compositions, kits and methods for treating scalp hair. The compositions include fluorinated (but not perfluorinated), non-polymeric compounds in a suitable excipient to provide beneficial effects on hair.
1. A method for treating scalp hair comprising the step of applying to hair a non-toxic composition comprising a non-perfluorinated, non-polymeric compound of formula (I)
wherein X is selected from the group consisting of CH 2 , CHCH 3 , and CCH 3 CH 3
wherein R 1 and R 2 are independently selected from the group consisting of hydrogen, cyclic C 3 -C 20 aliphatic acyclic C 1 -C 20 aliphatic, cyclic C 3 -C 20 heteroaliphatic acyclic C 1 -C 20 heteroaliphatic, cyclic C 3 -C 20 acyl acyclic C 1 -C 20 acyl, C 6 -C 20 aryl, heteroaryl, —OC(═O)R, —COOR A , —C(═O)R A , —OH, —NR B R C , and —CONR B R C ,
wherein R is an alkenyl radical,
R A , R B and R C are independently selected from the group consisting of hydrogen, cyclic C 3 -C 20 aliphatic acyclic C 1 -C 20 aliphatic, cyclic C 3 -C 20 heteroaliphatic acyclic C 1 -C 20 heteroaliphatic, cyclic C 3 -C 20 acyl acyclic C 1 -C 20 acyl, C 6 -C 20 aryl, and heteroaryl, which groups may be substituted or unsubstituted wherein heteroaryl is selected from the group consisting of pyridyl, pyrazinyl, pyrimidinyl, pyrrolyl, pyrazolyl, imidazolyl, thiazolyl, oxazolyl, isooxazolyl, thiadiazolyl, oxadiazolyl, thiophenyl, furanyl, quinolinyl, and isoquinolinyl,
wherein R 1 and R 2 may be substituted or unsubstituted, provided that R 1 and R 2 taken together contain at least three carbon atoms, R 1 and R 2 taken together are substituted with a total of at least four fluorine atoms, and R 1 and R 2 taken together contain no more than one aromatic ring structure, and provided that the compound of formula (I) does not contain an Si—O bond, is not a polyether, a fluorinated acid, an oxyacetamide, or a carbonate,
wherein the composition does not contain a free radical initiator, a polymerization initiator or a polymerization catalyst, and
wherein hair treated with the composition has at least 4 percent decreased moisture flux as measured according to DVS Protocol I and has no more than 15 percent weight gain when subjected to Starch Test I.
