Abstract

The invention relates to a polymer-micelle complex. The polymer-micelle complexes include a negatively charged micelle that is electrostatically bound to a water-soluble polymer bearing a positive charge. The polymer does not comprise block copolymer, latex particles, polymer nanoparticles, cross-linked polymers, silicone copolymer, fluorosurfactant or amphoteric copolymer. The compositions do not form a coacervate, and do not form a film when applied to a surface.

Cleaning product formulations rely on surfactants md mixtures of surfactants to deliver cleaning (deteigeoey), wedlng of surfaces,, stain removal from fsbrics, bleaching of stains, decolorkatioxi of mold a d mildew, and ¾ some cases, ai imierobiaf efficacy, A key aspect of these p cesses is the Interaction of the soriactaiits, oxidants, and antimicrobial agents with he solid su faces of the mater als being cleans!, as well as the surfaces of ffiicroofgaaisms, together with, the effects of the formati ns on the alo-water mterfaee (surface tesion). Reducti n of the surface tension of aqueous foundations, which is directly relate to the effectiveness of the: wetting of solid .surfaces and hem® e detergersey rid antimicrobial processes, cars be mani ulate through the use of mixtures of x n detants, as Is known in the art.
H J At a rsoleeukr level .surfactants md ai&etant mixtures in ueous media exhibit the ability to adsorb at tie air-water, solid-water, arid oil-water interfaces, and this adsorption is fence res onsible for a wide range of phen mena, including the sol bi iza ion of oils in the detergersey process, the changes la the properties of solids sad dispersions of solids, and the lowering of the -surface ension of water. Adsorption of surfactants at interfaces is generally known to increase with surfactant concentration «p to ¾ total surfactant eoneeno;ailon known as the critical micelle concentration (CMC). At die CMC, surf&etots begin to form aggregates In the boik sedation known as micelles. In equilibrium with the monomerle species of surfactants which a sor onto the Interfaces.
ffl M] The details of the structures sad sixes of the rn elles, as wed as the properties of the adsorbed layers of surssctasta or surfactant omiures, depend on the details of die molecular shape and charges, If y, on the hydrophdic 4¾eadgroupsw of the surfactants. Strongly charged aesdgroups of surfactants iend to repel each other at interfaces, opposing the efficient packing of the surfactants at the interface, and also favoring micelle structures thai are relatively small, d spherical. The charged headgrou s of many su fac ants, such s sulfates and sulfates, will also Introduce a eountenoo -of opposite olmrgsf for example a sodium or potassium toe. Mo femirdations.
|# S) It is know that the nature of t e eouaterion cm affect the repulsion between charged surfactants micelles nd adsorbed layers through a partial serosa ing of the feadgroup charges f om one aooiher m surfaeiam aggregates like mkehes, It is also well known that addition of simple eleehtdytes, such as sodium chloride, into aqueous solutions can also be used to Increase the screening of like headgroap charges from each other, and th s is & common parameter used to adjust the properties of surfactant micelles, such as siz and shape, and to adjust the adsorption of surfactants onto surfaces.
|©0O Addition of significant am unts of simple electrolytes into many fomtulstions, such as hard surface spray c eaners or nonwoven wipes loaded with a cleaning lotion, is undesirable due to residues left behmd upon drying of the bno latious. An alternative method, to admsimg the properties oi such formulations,, including the wetting of solid surfaces and stm on em, or the xwt&ag sad interactions with microbes, is to include signirlesnt amounts of volatile organic- solvents such as lower alcohols or glycol ethers. Volatile or anic solvents, however, are gommg under increasing regulation due to their potential health effects, and are eo preferred by the significant traction of consumers o desire efficacious cleaning and disinfecting products with a .minimum, of chemical actives, Including vo!ailles, in th healthcare industry- efficacious immolations comprising lower alcohols ajs kno n, but ate viewed as having shortcomings in terms of the potential for Irritation of confined patients. Such products pose similar risks to cleaning and clinical persotmel may be exposed to such products on a daily basis.
|0 ?| There is increasing interest om consumers, and a known need in the healthcare and housekeeping industries, to reduce the number of microorganisms on fabrics while using familiar equipment such as w&s ing machines. Concentrated products are required for such an application, doe to the high dilution lev l of the product the rinse-water, typically by a factor of about 600 times dilution. In the ease of lobula ion comprising quaternary ammonium compounds, lege concentrations of the quaternary ammonium compounds m the concentrate are eaded in order to ensure an adequate amount of adsorption oocers in a kineficai.lv relevant rime onto the microbes under dilution use conditions. As detailed above, it is desirable, yet very difficult to manipulate (i.e., reduce} the CMC of the quaternary ammonium so pound in. syc¾-:sis application. Thus very high concentration of quaternary attunonlum com unds, which tend to be hazardous to the skin, and eyes, arc used in lbs concentrates, in comb nation with hign teamerahnes a d kmg exposure times.
Thus, there is an ongoi g need for methods &ηά compositions offering See control of the properties of surfactant aggregates, m order to reduce or elimin te volatile organic solvents. There is also m o going need to deliver mm removal and/or sohmisrobial activity due to the action of oxidants such as sodinrn hypochlorite on s rf ces which are relatively difficult to wet with lower overall surfactant concentrations,

The polymers may be bomepolymers or copolymers, rid they may be !kear or branched. Linear polymers ma be preferred la at least seme embodiments. Copolymers may be synthesized by processes expected to lead to statistically random or so-called gradient type copolymers. In contrast, water-soluble block copolymers are not suitable, since these types of polymers may form aggregates or micelles, in which the more hydrophobic block or- blocks comprise the core of the aggregates or mfcsiles and the more nydrophi!!c block comprises 8 ^cor n " region k contact with water, ft Is thought that these self-assembly processes compete with the electrostatic interactions required for a watewsokfele polymer to serve as a polymeric soonterlsn with ordkary surfeclsnt micelles. Although .mixtures of water-soluble polymers are suitable Irs at least some embodiments of the present Inveofioo, the mixtures selected s ould not comprise block copolymers capable of farming so-called "complex eoacervate" micelles through self-assembly, skce this micelle formation process also com et s with the kter&ctioo of the water-soluble polymer as a polymeric eoosterloa to ordinary surfactant mtcslks. When the polymers are copolymers, the ratio- of the two or mo e monomers may vary over a wide range, ¾s long as water aofobOiby of the polyrnei is m intained.
