Definitions

• the present invention relates to physically stable liquid cleaning compositions comprising a nonionic surfactant, a polymer and a particular amphoteric surfactant.
• These liquid compositions may be used in various cleaning applications including laundry, softening, carpet cleaning, dishwashing, household cleaning, especially hard-surface cleaning, glass cleaning or toilet bowl cleaning, in oral/dental compositions and beauty care applications.
• liquid aqueous cleaning compositions have been disclosed in the art. For example much of the focus for liquid cleaning compositions has been on providing outstanding cleaning on a variety of surfaces and soils. Thus, liquid cleaning compositions have been developed based on various cleaning/soil releasing ingredients to improve their overall cleaning performance.
• co-pending European application number 97870018.5 discloses liquid aqueous cleaning compositions particularly suitable for the cleaning of a hard-surface, comprising an antiresoiling polymer (i.e., a copolymer of N-vinylpyrrolidone and alkylenically unsaturated monomer or mixtures thereof) and nonionic surfactants.
• a drawback associated with the formulation of such liquid aqueous cleaning compositions comprising at least a nonionic surfactant and a polymer like a polyvinylpyrrolidone homopolymer or copolymer is that they tend to be physically unstable. Indeed, the presence of such polymers like a polyvinylpyrrolidone homopolymer or copolymer in a liquid aqueous nonionic surfactant-containing composition can result in a hazy composition upon prolonged periods of storage, typically several days, or even immediately upon their incorporation in the composition, depending on the relative concentration of the nonionic surfactants and the polymers, and more particularly on the concentration of the nonionic surfactants.
• the object of the present invention is to formulate liquid aqueous cleaning compositions, especially so-called “concentrated” liquid cleaning compositions, comprising at least a nonionic surfactant and a polymer, which exhibit improved physical stability.
• the physical stability of a liquid aqueous composition comprising at least a nonionic surfactant and a polymer, is improved by adding into this composition a particular amphoteric surfactant as defined herein after.
• the present invention provides concentrated liquid aqueous compositions, comprising at least a nonionic surfactant at a level of 6% or more by weight of the total composition, a polymer and such an amphoteric surfactant which are physically stable upon prolonged periods of storage.
• An advantage of the present invention is that this invention is applicable to a wide range of cleaning operations including the cleaning/washing of fabrics or even bleaching of fabrics in the embodiment of the present invention wherein the compositions according to the present invention further comprise a bleaching agent, any household application, dishwashing applications, carpet applications or even dental applications or beauty care applications.
• compositions herein may be used to clean any surface including animate surfaces (human skin, and/or mouth) and inanimate surfaces including, but not limited to fabrics, clothes, carpets and any hard-surface made of a variety of materials like glazed and non-glazed ceramic tiles, vinyl, no-wax vinyl, linoleum, melamine, glass, plastics, plastified wood, both in neat and diluted conditions, e.g., up to a dilution level of 1:400 (composition:water).
• compositions of the present invention find preferred application in the cleaning of a hard-surface.
• the compositions of the present invention comprising the nonionic surfactant, the amphoteric surfactant and a homopolymer or copolymer of vinylpyrrolidone as the polymer, further comprise an antiresoiling ingredient selected from the group of a polyalkoxylene glycol, mono- or di-capped polyalkoxylene glycol or a mixture thereof, particularly improved cleaning is provided.
• these preferred liquid cleaning compositions provide both effective first and next-time cleaning performance when used to clean a hard-surface.
• these cleaning performances are obtained with the compositions according to the present invention on various types of stains/soils including typical greasy stains like kitchen grease and other tough stains such as burnt/sticky food residues typically found in kitchens, while delivering good gloss to said surfaces.
• compositions according to the present invention comprising the nonionic surfactant, the amphoteric surfactant and a polymer as defined herein, are that they have the ability to provide good shine to the surface they have cleaned. Indeed, less formation of watermarks and/or even limescale deposits are observed on a surface having been cleaned with the compositions of the present invention and later comes in contact with water, for example, during a rinse operation.
• the shine benefit delivered to the surface even persists after several cycles of rinsing, thus providing long lasting protection against formation of watermarks and/or even limescale deposits on the surface, and hence long lasting shiny surfaces.
• WO 94/26858 discloses a liquid hard-surface composition (pH 2-8) with nonionic surfactants (1-30%) and anionic polymers having an average molecular weight of less than 1 000 000, said polymers being free of quaternary nitrogen groups. Said compositions bring a surprising initial cleaning benefit in addition to the anti-soiling benefit. Indeed, WO 94/26858 discloses that acrylic, methacrylic and maleic anhydride derivatives such as copolymers of styrene with maleic, produce a streak-free finish after drying. No amphoteric surfactants according to the present invention are disclosed.
• EP-A-635 567 discloses liquid compositions for cleaning solid surfaces comprising a cleaning agent capable of being deposited on the surface during cleaning and of forming a dried layer adhered to the surface, said layer having a cohesive strength such that at least outermost surface portion of the layer is removable by further washing.
• a cleaning agent capable of being deposited on the surface during cleaning and of forming a dried layer adhered to the surface, said layer having a cohesive strength such that at least outermost surface portion of the layer is removable by further washing.
