Definitions

  • the present invention relates to general purpose, hard surface, liguid cleaning compositions comprising nonionic surfactants and polymeric components.
  • these compositions may come into contact with plastic surfaces such as the surfaces of baths, worktops and the like.
  • compositions for cleaning hard surfaces generally comprise one or more nonionic surfactants as cleaning agents involved in the removal of soil from the surface.
  • nonionic surfactants typically comprise alkoxylated alcohols described as compounds produced by the condensation of alkylene oxide groups, which are hydrophilic in nature, with an organic hydrophobic compound which may be aliphatic or alkyl aromatic in nature.
  • the length of the hydrophilic or polyoxyalkylene radical which is condensed with any particular hydrophobic group can be readily adjusted to yield a water-soluble compound having the desired degree of balance between hydrophilic and hydrophobic elements.
  • Particular examples include the condensation product of aliphatic alcohols having from 8 to 22 carbon atoms in either straight or branched chain configuration with ethylene oxide, such as a coconut oil ethylene oxide condensate having from 2 to 15 moles of ethylene oxide per mole of coconut alcohol; condensates of alkylphenols whose alkyl group contains from 6 to 12 carbon atoms with 5 to 25 moles of ethylene oxide per mole of alkylphenol.
  • Nonionic-based cleaning compositions can also contain perfumes to promote user acceptance and mask malodours and solvents to assist in cleaning. It is believed that the presence of nonionic surfactants, particularly in combination with solvents, promotes surface damage in plastics materials which have been stressed during use or manufacture. This surface damage can cause a loss of shine and/or structural failure of the materials.
  • the present invention is concerned with, overcoming at least in part, the problem of surface damage due to nonionic-surfactant containing compositions both in the presence or absence of solvents.
  • the invention provides for the use, in a plastics cleaning composition comprising nonionic surfactant, of a water soluble anionic polymer as an agent to retard propagation of surface cracks.
  • a further aspect of the present invention relates to a method for cleaning plastics surfaces which comprises the step of treating the surface with a cleaning composition of pH 2-10, comprising:
  • the ratio of polymer:nonionic is 0.1:1 or less.
  • compositions of the invention are both effective cleaners and far less aggressive towards surfaces.
  • damage to the plastic surface requires the plastic to be stressed in use or manufacture and the presence of a plasticising agent to weaken the plastic material such that the cracks formed by the stress can propagate. As the cracks lengthen and/or widen the material become structurally weak and the presence of the cracks causes a loss of surface finish. It is believed that, the presence of the polymer either retards the activity of the surfactant as a plasticiser or physically masks the surface to as to reduce access to the cracks.
  • the water soluble polymer is an essential component of the compositions according to the present invention.
  • the preferred polymers in embodiments of the present invention are those which are readily available in the marketplace. These are polymers of acrylic or methacrylic acid or maleic anhydride, or a co-polymer of one or more of the same either together or with other monomers.
  • Particularly suitable polymers include polyacrylic acid, polymaleic anhydride and copolymers of either of the aforementioned with ethylene, styrene and methyl vinyl ether.
  • the most preferred polymers are maleic anhydride co ⁇ polymers, preferably those formed with styrene, acrylic acid, methyl vinyl ether and ethylene.
  • the molecular weight of the polymer is at least, 5000, more preferably at least 50,000 and most preferably in excess of 100,000.
  • the surfactant based cleaning compositions comprise at least 0.01wt% polymer, on product.
  • the level of polymer is 0.05-5.0wt% at which level the anti-resoiling benefits become particularly significant. More preferably 0.2-2.0wt% of polymer is present.
  • higher levels of polymer do not give significant further cleaning advantages with common dilution factors, while increasing the cost of compositions. It is believed that high levels of polymer increase the viscosity of the product and hinder product wetting and penetration of the soil. However, for concentrated products which are diluted prior to use, the initial polymer level can be as high as 5%wt.
  • anionic polymers are those which carry a negative charge or similar polymers in protonated form. Mixtures of polymers can be employed.
  • the molecular weight of the polymer is preferably below 1 000 000 Dalton. It is believed that as the molecular weight increases the cleaning benefit of the polymer is reduced.
  • compositions according to the present invention comprise at least one nonionic surfactant.
  • the composition according to the invention comprise detergent actives which can be chosen from nonionic detergent actives. Suitable nonionic detergent active compounds can be broadly described as compounds produced by the condensation of alkylene oxide groups, which are hydrophilic in nature, with an organic hydrophobic compound which may be aliphatic or alkyl aromatic in nature.
  • the length of the hydrophilic or polyoxyalkylene radical which is condensed with any particular hydrophobic group can be readily adjusted to yield a water-soluble compound having the desired degree of balance between hydrophilic and hydrophobic elements.
  • Particular examples include the condensation product of aliphatic alcohols having from 8 to 22 carbon atoms in either straight or branched chain configuration with 2-15 moles of ethylene oxide.
  • Examples of such materials include a coconut oil ethylene oxide condensate having from 2 to 15 moles of ethylene oxide per mole of coconut alcohol; condensates of alkylphenols whose alkyl group contains from 6 to 12 carbon atoms with 5 to 25 moles of ethylene oxide per mole of alkylphenol; condensates of the reaction product of ethylenediamine and propylene oxide with ethylene oxide, the condensates containing from 40 to 80% of polyoxyethylene radicals by weight and having a molecular weight of from 5,000 to 11,000; tertiary amine oxides of structure R 3 N0, where one group R is an alkyl group of 8 to 18 carbon atoms and the others are each methyl, ethyl or hydroxy-ethyl groups, for instance dimethyldodecylamine oxide; tert
