摘要:
A water-in-oil emulsion system as a storage stable carrier of high pH sensitivity benefit agents or actives comprising i) an aqueous phase including at least one water soluble and/or dispersible benefit agent; ii) a hydrophobic protective carrier phase for the aqueous phase containing the benefit agent; and iii) an emulsifier or a dispersant. Also provided is a rinse off non-liquid cleansing composition comprising the water-in-oil emulsion system and a second phase which is a continuous alkaline phase.

A cleansing composition capable of enhancing deposition of benefit agent comprising: iv. a functional oil-in-water emulsion comprising 0.1% to 5% by weight benefit agent solubilised/dispersed in an oil and emulsified in water using a cationic emulsifier having an HLB greater than 8 such that the ratio of oil:cationic emulsifier is in the range 20:1 to 1:1; v. a detergent active composition comprising 5% to 80% detergent active; and vi. a cationic polymer.
摘要:
A rinse off liquid or gel cleansing composition comprising a continuous phase comprising one or more detergent actives and a dispersed phase comprising one or more hydrophobic materials, the dispersed phase comprising a water soluble or dispersible benefit agent which is sensitive to a detergent active and/or high pH, which benefit agent is dispersed in the hydrophobic material.

This invention is directed to a method of dewatering animal farm waste water comprising: (1) adding an effective amount of a cationic dispersion polymer having an RSV of at least 24, the dispersion polymer prepared by polymerizing under free radical forming conditions in an aqueous solution of a water-soluble salt in the presence of one or more particle stabilizing polymers (i) from about 20 to about 90 mole percent nonionic monomers and (ii) from about 10 to about 80 mole percent of cationic monomers wherein the cationic monomers are selected from at least one hydrophilic cationic monomer and at least one hydrophobic cationic monomer and wherein less than 50 percent of the cationic monomers on a molar basis are hydrophobic monomers, (2) mixing the waste water and the cationic dispersion polymer to form a mixture of water and flocculated solids and (3) separating the flocculated solids from the water.
摘要:
The invention provides a method of removing emulsified oil from an industrial wastewater stream. According to the method, a vinylamine polymer is added to the oil containing wastewater in a concentration of from about 0.1 to about 100 parts per million based on the total volume of the water being treated. The vinylamine polymer includes from about 1 to about 100 mole percent vinylamine and from about 1 to about 99 mole percent of at least 1 monomer selected from the group consisting of amidine, vinylformamide, vinyl alcohol, vinyl acetate, vinyl pyrrolidinone and the esters, amides, nitriles and salts of acrylic acid and methacrylic acid. The addition of the polymer to the oil containing wastewater causes the emulsified oil to flocculate. The flocculated oil is then removed from the wastewater.

A rinse off liquid or gel cleansing composition comprising a continuous phase comprising one or more detergent actives and a dispersed phase comprising one or more hydrophobic materials, the dispersed phase comprising a water soluble or dispersible benefit agent which is sensitive to a detergent active and/or high pH, which benefit agent is dispersed in the hydrophobic material.
摘要:
A method for removing emulsified oil from industrial waste water streams utilizing dispersion copolymers is disclosed. Preferred dispersion copolymers are poly(dimethylaminoethylacrylate methyl chloride quaternary salt/acrylamide) and poly (diallyldimethyl ammonium chloride/acrylamide).
摘要:
A water-soluble, cationic polymer comprising from about 1 to about 65 mole percent of one or more cationic monomers, from about 99 to about 35 mole percent of one or more nonionic monomers and from about 1 to about 1000 ppm, based on the total monomer content, of one or more hyperbranched monomers wherein the hyperbranched monomer contains from about 2 to about 20 allyl, vinyl, or acrylic end groups and method of dewatering sludge is disclosed.
摘要:
This invention is directed to structurally-modified water-soluble polymers prepared by initiating polymerization of an aqueous solution of monomers under free radical polymerization conditions to form a polymer solution and adding at least one structural modifier to the polymer solution after at least 30% polymerization of the monomers has occurred, and to use of the water-soluble cross-linked polymers as flocculating agents.
摘要:
Demulsification of a water-in-oil, especially a water-in-crude oil, emulsion is effected by contacting it with an aqueous composition having at least one oil-soluble demulsifier and at least one water-soluble surfactant. These aqueous formulations are advantageous over conventional organic formulations of demulsifiers, as the need for toxic and/or flammable/combustible organic solvents is eliminated.
