Definitions

  • the present invention relates to a cleaning composition and to a method of treating surfaces with the said composition.
  • Hard-surface cleaning compositions generally comprise one or more surfactants, and, optionally, one or more hygiene agents .
  • the surfactants used in such cleaning compositions are selected from anionic, nonionic, amphoteric and cationic surfactants.
  • Nonionics are very commonly used due to their effectiveness on fatty soils and the ease with which their foaming can be controlled.
  • a known manner in which foaming can be controlled involves including in the composition relatively low levels of a solubilised hydrophobic oil such as an iso-paraffin and a relatively low level on product of a surfactant such as a fatty acid soap which forms a calcium salt insoluble in dilute aqueous solution.
  • Both the oil and the soap components are soluble/miscible in the composition forming a stable product until (hard) water is added whereupon the combination of oil and the particles of calcium salt formed in situ acts as a 'foam breaker' for a second (main) surfactant.
  • the effect on the salt content of the composition on dilution with hard water it is known to exploit the changes in acidity/alkalinity which occur on dilution.
  • acidic general purpose cleaning compositions based on the high foaming anionic surfactant magnesium PAS and an organic acid such as citric are known which are neutralised to pH 4.0 with a base such as ammonia to give improved cleaning e fectiveness especially as regards lime soaps and lime scales whilst maintaining cleaning efficiency against fatty/greasy soils.
  • a base such as ammonia
  • compositions In addition to surfactants it is known to incorporate polymers in hard surface cleaning compositions. These polymers provide benefits both in initial and repeated cleaning. In order to obtain benefits from the presence of polymers it is often useful to formulate compositions in an acidic pH range. Typically the pH of the compositions is in the range 3-4.5, with preferred values around 4.5. Polymer containing compositions are difficult to antifoam: the presence of iso-paraffins and fatty acids reduce the performance in neat usage and, in particular, the recleaning properties of the product. Overall the isoparaffin/fatty acid antifoaming system does not provide a sufficiently low foam profile and ease of rinsability for some consumers. Brief Description of the Invention
  • an effective antifoaming system can be based on the synergism between four different components: a branched fatty chain nonionic including a small amount of free monobranched alcohol; a low level of ethoxylated/propoxylated nonionic surfactant and a fatty acid.

  • a second aspect of the present invention provides a process for cleaning surfaces which comprises the step of treating the surface with a composition of pH 2-6 comprising: l-30%wt on product of an alkoxylated nonionic surfactant, less than 50%wt of total surfactant of anionic surfactant and 0.005-5%wt on product of a water soluble, anionic polymer having an average molecular weight of less than 1,000,000, wherein, the ratio of polymer : nonionic is 0.1:1 or less, said product being CHARACTERISED IN THAT :
  • the ethoxylated nonionic surfactant is a material of the general formula: R- (EO) w -OH wherein EO is a residue of ethylene glycol, w is 1-10 and R is a C 8 - C 18 alkyl or alkyl phenyl group;
  • composition further comprises a monocarboxylic fatty acid of general formula: R.-COOH wherein R j is a C B -C l a alkyl group;
  • composition further comprises a mixed propoxylated/ethoxylated nonionic surfactant of general formula: R ? - [ (EO) x (PO) y ] -OH wherein EO and PO are residues of ethylene and propylene glycol, x is 1-10, y is 1-10, and R 2 is a C 8 -C 18 alkyl group, and,
  • composition further comprises a monobranched alcohol of the general formula R 3 -OH wherein R 3 is a branched C 8 -C 18 alkyl group.
  • Nonionic, ethoxylated surfactants are present in the compositions of the invention. These surfactants are believed to engage in a synergistic interaction with the polymer, to improve cleaning and aid the removal of soil subsequently deposited.

  • anionic polymers are those which carry a negative charge or similar polymers in protonated form. Mixtures of polymers can be employed. It should be noted that the beneficial effect of anionic polymers is significantly reduced by the presence of anionic surfactants.

Although both the normal and concentrated products can be used neat it will be commonplace for these to be diluted by the user before use. For sprayable products, which are seldom diluted prior to use, the concentration of the antimicrobial agent will be in the range 0.05-0.5%wt.
  • the ratio of the nonionic surfactant to the antimicrobial agent will preferably be in the range 50:1 to >1:1, more preferably 30:1 to >1 : 1 i.e. an excess of nonionic will be present relative to the antimicrobial.
  • benzoic acid derivatives a preferred antimicrobial agent is salicylic acid, which gives better hygiene results than benzoic and shows a very marked improvement as compared with sorbic acid.

  • composition according to the invention can contain other minor, inessential ingredients which aid in their cleaning performance and maintain the physical and chemical stability of the product.
  • the composition can contain detergent builders.
  • the builder when employed, preferably will form from 0.1 to 25% by weight of the composition.
  • the composition can include one or more amphoteric surfactants, preferably betaines, or other surfactants such as amine-oxide and alkyl-amino- glycinates.
  • amphoteric surfactants preferably betaines, or other surfactants such as amine-oxide and alkyl-amino- glycinates.
  • Betaines are preferred for reasons of cost, low toxicity (especially as compared to amine-oxide) and wide availability. It is believed that amphoteric surfactants show a slight synergy with some organic acids (when present) as regards antimicrobial effects.
  • Typical betaines in compositions according to the invention are the amido-alkyl betaines, particularly the amido-propyl betaines, preferably having an aliphatic alkyl radical of from 8 to 18 carbon atoms and preferably having a straight chain. These betaines are preferred as they are believed to comprise relatively low levels of nitrosamine precursors although other betaines, such as alkyl betaines, can be used in the compositions of the invention. Typical levels of amphoteric range from 0.01 to 8%, with levels of l-5wt%, particularly around 2% being preferred for normal compositions and up to four times the concentration being present in so called, concentrated products.
  • the nonionic surfactant As with the nonionic surfactant, lower levels or around 0.05-1% will be employed in sprayable products and higher levels of, typically, around 4%wt in concentrates. In general, the ratio of the betaine to the aromatic carboxylic acid will be in the range 1:3 to 3:1, with approximately equal levels on a weight basis being preferred.
  • Metal ion sequestrants including ethylenediaminetetraacetates , aminopolyphosphonates (such as those in the DEQUEST R range) and phosphates and a wide variety of other poly-functional organic acids and salts, can also optionally be employed. It is believed that the hygiene performance of the composition is improved by the presence of a metal ion sequesterant .
  • Hydrotropes are useful optional components. It is believed that the use of hydrotropes enables the cloud point of the compositions to be raised without requiring the addition of anionic surfactants.
  • anionic surfactants and betaine is believed to be detrimental to the formulations as these surfactants interact with the amphoterics, when present, and to form a complex which inhibits the synergistic hygiene activity of the amphoterics with the organic acid.
  • the formations according to the invention are free of anionic surfactants when betaine is present, or contain low levels of anionic surfactants, i.e. less than 50% of the total level of surfactant present and preferably less than 50% of the level of the betaine in the product.
  • Anionics are compatible with the solely alcohol ethoxylate based compositions of the present invention when the level is below 50%wt of the total surfactant present, but their level should be minimised in view of their interactions with the polymers .
  • the level of anionic is below 30% of the total surfactant content of the composition and more preferably below 10% of the surfactant content. It is possible to make compositions which contain little or no anionic surfactant.
  • Suitable hydrotropes include, alkali metal toluene sulphonates, urea, alkali metal xylene and cumene sulphonates, polyglycols, >20EO ethoxylated alcohols, short chain, preferably C 2 -C 5 alcohols and glycols. Preferred amongst these hydrotropes are the sulphonates, particularly the cumene, xylene and toluene sulphonates.
  • Typical levels of hydrotrope range from 0-5% for the sulphonates . Correspondingly higher levels of urea and alcohols are required. Hydrotropes are not always required for dilute, sprayable products, but may be required if lower EO or longer alkyl ethoxylates are used or the cloud point needs to be raised considerably. Typically, the cloud point of the final composition should preferably be in the range 45-50 Celcius. The cumene sulphonate is the most preferred hydrotrope.
  • ethoxylated nonionic levels of around 7%wt on product levels of SCS will generally be in the range 0.6-0.8wt% for ethoxylated nonionic levels of around 14%wt levels of SCS will generally be in the range 1.0-1.2wt%.
