The present invention relates to a block polymeric material. Typically the block polymer comprises units capable of having an average cationic charge density of about 15 or less, preferably 5 or less, more preferably from about 0.05 to about 5, even more preferably from about 0.05 to about 2.77, even more preferably from about 0.1 to about 2.75, most preferably from about 0.75 to about 2.25 units per 100 daltons molecular weight at a pH of from about 4 to about 12. The polymeric material is a suds enhancer and a suds volume extender for personal care products such as soaps and shampoos. The compositions have increased effectiveness for preventing re-deposition of grease during hand and body washing. The polymers are also effective as a soil release agent in fabric cleaning compositions. The polymeric material is also effective in oil well treating foam, fire-fighting foam, hard surface cleaning foam, shaving cream, post-foaming shaving gel, dephiliatories and as a coagulant/retention aid for titanium dioxide in paper making.

Block polymers, compositions and methods for use for foams, laundry detergents, and shower rinses and coagulants

A polymeric material including units capable of having a cationic charge at a pH of from about 4 to about 12; provided that the polymeric material has an average cationic charge density from about 2.75 or less units per 100 daltons molecular weight at a pH of from about 4 to about 12. The polymeric material is a suds enhancer and a suds volume extender for hand dishwashing compositions and personal care products such as soaps, shaving cream foam, foaming shaving gel, foam depiliatories and shampoos. The polymers are also effective as a soil release agent in fabric cleaning compositions. The polymers are also useful in agrochemical foam, fire-fighting foam, hard surface cleaner foam, and coagulant for titanium dioxide in paper making.

The present invention relates to methods for using polymeric suds enhancers (stabilizers) to increase the suds and/or foam volume and suds and/or foam retention in suds-forming and/or foam-forming compositions comprising such polymeric suds stabilizers. Suitable suds-forming and/or foam-forming compositions comprise one or more polymeric suds stabilizers. The polymeric suds stabilizers suitable for use in the methods and/or compositions of the present invention comprise cationic, anionic, and noncharged monomer units, or units having mixtures thereof, wherein said polymers have an average cationic charge density from about 0.05 to about 5 units per 100 daltons molecular weight at a pH of from about 4 to about 12.

Compositions and methods for using polymeric suds enhancers

The present invention relates to methods for using amine oxide monomer-containing polymeric suds enhancers (enhancers) to increase the suds and/or foam volume and suds and/or foam retention in suds-forming and/or foam-forming compositions comprising such amine oxide monomer-containing polymeric suds enhancers. Suitable suds-forming and/or foam-forming compositions comprise one or more amine oxide monomer-containing polymeric suds enhancers.

The invention concerns the use, in an aqueous spray mixture comprising a phytosanitary formulation, of an anti-leaching agent comprising: at least a polyhydroxyl and/or polycarboxyl polymer or copolymer; at least a crosslinking agent comprising a metal selected among columns IVA, IB and IIIB of the periodic table; said anti-leaching agent being, in the aqueous spray mixture, in the form of an aqueous solution or dispersion having a polymer or copolymer concentration such that the viscosity of the anti-leaching agent is not more than 10 times the viscosity of the aqueous solution in polymer or copolymer without crosslinking agent, having the same concentration.

Use of crosslinked polymers as anti-leaching agents

The invention relates to the use of a copolymer or a mixture of copolymers as foam-protecting agents in detergent or cosmetic formulations, comprising at least one monomer (I) selected from the acids, diacids or unsaturated C3-C5 anhydrides; or at least one monomer (II) selected from ethylene oxide and propylene oxide; or at least one monomer (III) selected from the linear or branched C4-C8 hydrocarbons, comprising at least one ethenoid unsaturation; or at least one monomer (IV) of formula R1 &mdash;COO&mdash;R2, where R1 is a possibly substituted linear or branched C1-C3 hydrocarbon radical; R2 is a linear or branched C1-C4 hydrocarbon radical which is possibly substituted by an anionic radical or a hydroxyl group; and the monomer (IV) further comprises at least one ethenoid unsaturation.
