Abstract

Abstract A quaternized polymer having recurring units of the formula <IMAGE> wherein X(-) represents an anion derived from an organic or mineral acid; R'2 is an aliphatic radical having a maximum of 20 carbon atoms; R'1 is an aliphatic, alicyclic or arylaliphatic radical containing a minimum of 2 carbon atoms and a maximum of 20 carbon atoms, or R'1 and R'2 together with the nitrogen atom to which they are attached form a ring capable of containing a second heteroatom other than said nitrogen; A represents a divalent group of the formula <IMAGE> wherein x, y and t are whole numbers ranging from 0 to 11 and being such that the sum (x+y+t) is greater than or equal to 0 and less than 18, and E and K represent hydrogen or an aliphatic radical having less than 18 carbon atoms; B represents a divalent group of the formula <IMAGE> CH2CHOHCH2, +TR <IMAGE> wherein D and G represent hydrogen or an aliphatic radical having less than 18 carbon atoms and v, z, and u are whole numbers ranging from 0 to 11, two of them being able to be simultaneously equal to 0 such that the sum (v+z+u) is greater than or equal to 1 and lower than 18, and such that the sum (v+z+u) is greater than 1 when the sum (x+y+t) is equal to 0, and n is a whole number equal to 2 or 3. The polymers are usefully employed in cosmetic compositions for application to the hair or skin.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 254 words
A process for treating the hair to improve the qualities thereof comprising applying to the hair an effective amount of a cosmetic composition comprising an aqueous, alcoholic or hydroalcoholic solution of an effective amount of at least one quaternized polymer having recurring units of the formula ##STR20## wherein X.sup.⊖ represents an anion derived from an organic or mineral acid; R' 2 is an aliphatic radical having a maximum of 20 carbon atoms; R' 1 is alkyl containing 2-20 carbon atoms, cycloalkyl having 5 or 6 carbon atoms or phenylalkyl wherein the alkyl moiety has 1-3 carbon atoms, or R' 1 and R' 2 together represent a polymethylene radical having 4 or 5 carbon atoms or --(CH 2 ) 2 --O--(CH 2 ) 2 --, A represents a divalent group of the formula ##STR21## wherein x, y and t are whole numbers ranging from 0 to 11 and being such that the sum (x+y+t) is greater than or equal to 0 and less than 18, and E and K represent hydrogen; B represents a divalent group of the formula ##STR22## wherein D and G represent hydrogen and v, z and u are whole numbers ranging from 0 to 11, two of them being able to be simultaneously equal to 0 such that the sum (v+z+u) is greater than or equal to 1 and lower than 18, and such that the sum (v+z+u) is greater than 1 when the sum (x+y+t) is equal to 0, and n is a whole number equal to 2 or 3.
Claim 2
Dependent Claim 254 words
A process for treating the hair to improve the qualities thereof comprising applying to the hair an effective amount of a cosmetic composition comprising an aqueous, alcoholic or hydroalcoholic solution of an effective amount of at least one quaternized polymer having recurring units of the formula ##STR20## wherein X.sup.⊖ represents an anion derived from an organic or mineral acid; R' 2 is an aliphatic radical having a maximum of 20 carbon atoms; R' 1 is alkyl containing 2-20 carbon atoms, cycloalkyl having 5 or 6 carbon atoms or phenylalkyl wherein the alkyl moiety has 1-3 carbon atoms, or R' 1 and R' 2 together represent a polymethylene radical having 4 or 5 carbon atoms or --(CH 2 ) 2 --O--(CH 2 ) 2 --, A represents a divalent group of the formula ##STR21## wherein x, y and t are whole numbers ranging from 0 to 11 and being such that the sum (x+y+t) is greater than or equal to 0 and less than 18, and E and K represent hydrogen; B represents a divalent group of the formula ##STR22## wherein D and G represent hydrogen and v, z and u are whole numbers ranging from 0 to 11, two of them being able to be simultaneously equal to 0 such that the sum (v+z+u) is greater than or equal to 1 and lower than 18, and such that the sum (v+z+u) is greater than 1 when the sum (x+y+t) is equal to 0, and n is a whole number equal to 2 or 3.
