Assignee: THE PROCTER & GAMBLE COMPANY
Field: Basic materials chemistry (Chemistry)
Classification: CPC C  B | IPC B  C

Claim 16:
17. The composition according to claim 1, further comprising from about 0.05% to about 2% by weight of the total composition of an amphiphilic alkoxylated polyalkyleneimine and mixtures thereof, wherein the amphiphilic alkoxylated polyalkyleneimine is an alkoxylated polyethyleneimine polymer comprising a polyethyleneimine backbone having a weight average molecular weight range of from about 100 to about 5,000 Daltons, and the alkoxylated polyethyleneimine polymer comprises the following modifications:
i) one or two alkoxylation modifications per nitrogen atom, dependent on whether the modification occurs at an internal nitrogen atom or at an terminal nitrogen atom, in the polyethyleneimine backbone, the alkoxylation modification consisting of the replacement of a hydrogen atom on by a polyalkoxylene chain having an average of about 1 to about 50 alkoxy moieties per modification, wherein the terminal alkoxy moiety of the alkoxylation modification is capped with hydrogen, a C1-C4 alkyl or mixtures thereof;
ii) a substitution of one C1-C4 alkyl moiety and one or two alkoxylation modifications per nitrogen atom, dependent on whether the substitution occurs at a internal nitrogen atom or at an terminal nitrogen atom, in the polyethyleneimine backbone, the alkoxylation modification consisting of the replacement of a hydrogen atom by a polyalkoxylene chain having an average of about 1 to about 50 alkoxy moieties per modification wherein the terminal alkoxy moiety is capped with hydrogen, a C1-C4 alkyl or mixtures thereof; or
iii) a combination thereof; and
wherein the alkoxy moieties are selected from ethoxy (EO), propoxy (PO), butoxy (BO), and mixtures thereof, with the proviso that the alkoxy moieties do not solely comprise ethoxy units, wherein the polyalkoxylene chain is ethoxy/propoxy block moieties having an average degree of ethoxylation from about 3 to about 30 and an average degree of propoxylation from about 1 to about 20.
