Abstract
The present invention relates to processes for the manufacture of aminated or functionalized aminated polymers and their use in water-borne compositions. More specifically, this invention relates to personal care compositions containing aminated polymers and one or more other conditioning agents, surfactants and other active or inactive ingredients.
Claims33
An aqueous personal care composition comprising a conditioner and a polymer functionalized with an amino group, wherein the amino group is pendant and the polymer functionalized with an amino group has the following structure:
- and, wherein the polymer comprises a natural, semisynthetic or synthetic polymer;
- X comprises an oxygen, nitrogen or sulfur atom, or a polyalkylene oxide group;
- Y comprises a bivalent polyalkylene or substituted bivalent polyalkylene moiety;
- R1 and R2 may be the same or different and comprise hydrogen, C1-C20 alkyl, C1-C20 aryl or C1-C20 alkyl(aryl) group;
- n comprises an integer between 0 and 10;
- Z′ comprises a counteranion, and
- wherein the conditioner is selected from the group consisting of cationic surfactants, cationic polymers, nucleic acids, lipids, silicones, hydrocarbon oil, fatty esters and combinations thereof.
An aqueous personal care composition comprising a conditioner and a polymer functionalized with an amino group, wherein the amino group is part of the polymer's backbone:
- R3-(A)m-(B)n-R4
- wherein the conditioner is selected from the group consisting of cationic surfactants, cationic polymers, nucleic acids, lipids, silicones, hydrocarbon oil, fatty esters and combinations thereof, and wherein A is a residue of a monomer or a group of monomers devoid of an amino group and B is an aminating monomer or a group of aminating monomers, m is an integer between 0 and 100 and n is an integer between 1 and 100;
- R3 and R4 is H or C1-C25 hydrophobic groups and wherein B has the following structure:
- where —C—N(R5)-D- is a residue of the aminating monomer or group of aminating monomers, C and D are hydrophilic or hydrophobic functionalized moieties and R5 is H or C1-C25 hydrophobic groups.
