Abstract
The present invention relates to cleaning compositions with improved rinse suds profile, which comprise an alkoxylated polyalkyleneimine, an organomodified silicone and a siloxane-based diluent.
Claims22
A cleaning composition comprising:
- (a) at least one alkoxylated polyalkyleneimine comprising a polyalkyleneimine core and at least one side chain bonded to a nitrogen atom in the polyalkyleneimine core, wherein the polyalkyleneimine core has an average number-average molecular weight (MWn) ranging from 100 to 100,000 Daltons, and wherein said at least one side chain has an empirical formula (I) of:
- -(EO)b(PO)c—R (I)
- wherein:
- EO is ethylene oxide;
- b has a weight average value ranging from 3 to 60;
- PO is propylene oxide;
- c has a weight average value ranging from 0 to 60;
- R is selected from the group consisting of hydrogen, C1-C4 alkyls, and combinations thereof;
- (b) an organomodified silicone comprising one or more aryl moieties each comprising a 5- to 9-membered aromatic ring, wherein said aromatic ring can be either substituted or unsubstituted, either heteroatomic or homoatomic, either monocyclic or multicyclic;
- and
- (c) from about 0.001 wt % to about 10 wt % of a siloxane-based diluent comprising a first polydimethylsiloxane having a first, higher viscosity and a second polydimethylsiloxane having a second, lower viscosity, and wherein the weight ratio of said first polydimethylsiloxane to said second polydimethylsiloxane is greater than 1:1, said diluent having a Solubility Index of from 0.8 to 1.25 in said organomodified silicone.

A liquid detergent composition comprising:
- (a) from 1 wt % to 5 wt % of at least one alkoxylated polyalkyleneimine comprising a polyalkyleneimine core and at least one side chain bonded to a nitrogen atom in the polyalkyleneimine core, wherein the polyalkyleneimine core has an average number-average molecular weight (MWn) ranging from 200 to 1000 Daltons, and wherein said at least one side chain has an empirical formula (I) of:
- -(EO)b(PO)c—R (I)
- wherein:
- EO is ethylene oxide;
- b has a weight average value ranging from 20 to 30;
- PO is propylene oxide;
- c has a weight average value ranging from 10 to 30;
- R is hydrogen;
- (b) from 0.02 wt % to 0.5 wt % of an organomodified silicone, which comprises from 10 mol % to 40 mol % of siloxane units containing a 2-phenylpropyl moiety and from 3 mol % to 10 mol % of siloxane units containing a C6-C10 alkyl moiety;
- (c) from 0.02 wt % to 0.5 wt % of a siloxane-based diluent comprising a first polydimethylsiloxane having a first, higher viscosity and a second polydimethylsiloxane having a second, lower viscosity, and wherein the weight ratio of said first polydimethylsiloxane to said second polydimethylsiloxane is greater than 1:1, said diluent having a Solubility Index of from 0.85 to 1 in said organomodified silicone;
- (d) from 0.002 wt % to 0.05 wt % of a hydrophobically modified silica;
- (e) from 0.002 wt % to 0.05 wt % of a silicone resin;
- (f) from 5 wt % to 30 wt % of an anionic surfactant selected from the group consisting of C10-C20 linear alkyl benzene sulphonates, C10-C20 linear or branched alkylethoxy sulfates having an average degree of ethoxylation ranging from 0.5 to 3, methyl ester sulfonates with a C10-C20 linear or branched alkyl group, and combinations thereof;
- (g) optionally, from 0.5 wt % to 20 wt % of an amphoteric surfactant and/or a zwitterionic surfactant;
- (h) optionally, from 0.1 wt % to 10 wt % of a nonionic surfactant;
- and
- (i) water.
