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 14 (hydrophilic-lipophilic balance) and at least a second nonionic surfactant with an HLB below 9 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 14 and at least a second surfactant with an HLB below 9 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 14 and at least a second nonionic surfactant with an HLB below 9 ; also, the user needs less product to achieve the same task.
  • This advantage is particularly valuable in terms of environmental compatibility.

  • FR 2013 197 fails to disclose the presence of an ionic 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.

  • 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.

  • an aqueous cleaning composition comprising 2-6% of an anionic surfactant and from 4 % to 30 % by weight of the total composition of a nonionic surfactant system, whereby said nonionic surfactant system comprises at least 2% by weight of the total composition of a first surfactant with an HLB of at least 14 and at least 2 % by weight of the total composition of a second surfactant with an HLB below 9, is diluted in water so as to obtain from 0.001 % to 5 % by weight of the total composition of said nonionic surfactant system and subsequently applied to said hard surface.
  • said composition is diluted into 10 to 200 times its weight of water, more preferably 50 to 150 times, before it is applied to said hard surface.
  • compositions were tested for their cleaning performance when used diluted on greasy soil.
  • compositions were made by mixing the listed ingredients in the listed proportions: Compositions: #1 #2 Ingredients: Weight % Sodium paraffin sulfonate 3 3 Alcohol ethoxylate 7EO (1) 4 - Alcohol ethoxylate 30EO (2) - 2 Alcohol ethoxylate 3EO (3) - 2 Sodium Citrate 3 3 Butylcarbitol R 4 4 Triethanolamine 1 1 water & minors up to 100%
  • (1) is an ethoxylate nonionic surfactant representative of the prior art with an HLB of 12.
  • Compounds (2) and (3) are ethoxylate nonionic surfactants according to the present invention.
  • (2) is a highly hydrophilic nonionic surfactant with an HLB of 17, wherein R is a mixture of C13 and C15 alkyl chains and n is 30.
  • (3) is a highly hydrophobic nonionic surfactant with an HLB of 8, wherein R is a mixture of C13 and C15 alkyl chains and alkyl chains and n is 3.
  • compositions 1-2 described hereinabove can be used neat or diluted. In the present cleaning performance test these compositions are diluted in 64 times their weight of water and subsequently applied to a hard surface.
  • composition #1 which comprises a nonionic surfactant with an moderate HLB (12) gets a cleaning index of 100 and is used as a reference.
  • the composition #2 which comprises a nonionic surfactant system comprising alcohol ethoxylate 30EO (an highly hydrophilic nonionic surfactant) and alcohol ethoxylate 3EO (an highly hydrophobic nonionic surfactant) exhibit outstanding cleaning performance upon dilution both in hard and soft water. Indeed, when used with hard water the composition #2 is almost four times more efficient than the composition #1 and when used with soft water the composition #2 is two times more efficient than the composition #1.
