Definitions

  • the present invention relates to cleaning compositions. Although the present invention applies primarily to hard surface cleaning compositions, it may also be of interest for other cleaning compositions including dishwashing and laundry detergent compositions.
  • compositions which can be used in diluted form are known in the art.
  • the technical problem lies in sustaining upon dilution an efficient cleaning performance.
  • Such compositions for dilute cleaning are described for instance in the European Patent EP-A- 0 503 219.
  • the dilute cleaning performance is obtained by using alkanolamines.
  • This '219 patent application also mentions the use of nonionic surfactants among which ethoxylated fatty alcohols are listed.
  • Hard surface cleaning compositions comprising various surfactants, including highly ethoxylated nonionic surfactants, which can be used in diluted form are also known in the art. Representative of this prior art are the compositions described in European Patent Application EP-A-561103.
  • cleaning compositions comprising a specific nonionic surfactant system. Indeed, it has been found that cleaning compositions comprising at least a first nonionic surfactant with an HLB of at least 12(hydrophilic-lipophilic balance) and at least a second nonionic surfactant with an HLB below 10 and at least 4 less than the HLB of said first surfactant exhibit a great flexibility in the soils it may clean. These compositions unexpectedly exhibit outstanding cleaning performance upon dilution, compared to compositions comprising typical nonionic surfactants while the cleaning performance of the neat, i.e. undiluted compositions is similar, regardless of the presence of said nonionic surfactant system.
  • the cleaning compositions comprising a nonionic surfactant system of at least a first surfactant with an HLB of at least 12 and at least a second surfactant with an HLB below 10 and at least 4 less than the HLB of said first surfactant exhibit outstanding cleaning performance when used both neat and diluted.
  • compositions according to the present invention are especially effective on greasy soils, both when used in hard water and also when used in soft water.
  • a particular advantage of the present invention is robustness to different usage conditions, e.g. variations in water hardness used for diluting the product.
  • This invention is also particularly useful as it allows to formulate compositions with reduced levels of other ingredients, yet retaining optimal cleaning performance, due to said combination of at least a first nonionic surfactant with an HLB of at least 12 and at least a second nonionic surfactant with an HLB below 10 and at least 4 less than the HLB of said first surfactant; also, the user needs less product to achieve the same task.
  • This advantage is particularly valuable in terms of environmental compatibility.
  • FR-A-2 013 197 discloses laundry spotter compositions comprising a mixture of two different alcohol ethoxylated/propoxylated nonionic surfactants, i.e. one alcohol ethoxylated nonionic surfactant with 3 to 12 ethoxy groups and one alcohol ethoxylated nonionic surfactant with 1 to 8 ethoxy groups.
  • FR 2 013 197 fails to disclose the presence of anionic surfactants.
  • FR 2 013 197 nowhere discloses a method of cleaning a hard surface wherein an aqueous composition according to the present invention, is diluted in water and subsequently applied to said hard surface
  • GB-A-2 011 944 discloses a stable low foaming unbuild aqueous liquid composition with 25% to 45% by weight of a ternary non-ionic detergent mixture wherein the nonionic surfactants are high-, medium-, and low-ethoxylated primary saturated fatty alcohols with specific alcohol chains.

No anionic surfactants are disclosed. Also EP-A-0 497 337 nowhere discloses a method of cleaning a hard surface wherein a composition according to the present invention, is diluted in water and subsequently applied to said hard surface.
  • EP-A- 475 002 discloses a thickened acidic aqueous composition comprising an acid, a C10-C18 fatty alcohol ethoxylate (8-14 ethylene oxide) and a thickener comprising an ethoxylate of a C10-C18 fatty alcohol with 1-7 ethylene oxide and less than 5% of free fatty alcohol. No anionic surfactants are disclosed. Also EP-A-475 002 nowhere discloses a method of cleaning a hard surface wherein a composition according to the present invention, is diluted in water and subsequently applied to said hard surface.
  • EP-A- 379 256 discloses stable acidic all-purpose liquid cleaning compositions comprising from 0.5% to 4% by weight of a stable nonionic surfactant mixture, an organic acid and an acid stable anti- microbial compound.
  • Said stable nonionic surfactant system consists essentially of a water soluble nonionic surfactant and a water dispersible nonionic surfactant in a weight ratio of water soluble to water dispersible nonionic of from 4:1 to 4:3. No anionic surfactants are mentioned.
  • EP-A- 379 256 nowhere discloses a method of cleaning a hard surface wherein a composition according to the present invention, is diluted in water and subsequently applied to said hard surface.
  • WO-A-91/03540 discloses particular mixtures of alkali-resistant polyalkylene glycol ethers with a foam suppressing action. No anionic surfactants are mentioned. Also WO-A-91/03540 nowhere discloses a method of cleaning a hard surface wherein a composition according to the present invention, is diluted in water and subsequently applied to said hard surface.
