Definitions

  • the present invention relates to a cleaner composition, more specifically, the present invention relates to a concentrated cleaner composition particularly for business use, which is suitable for removing oxidized grease stains adhering to the surface of floor, wall and cooking instruments in the kitchen, particularly denatured grease stains.
  • cleaners for washing and removing the stain of oils and fats have been used after selecting a cleaner depending on the kind of the grease stain.
  • the cleaner used comprises a surfactant and a solvent.
  • a cleaner mainly used for removing grease stains adhering to the surface of floor, wall and cooking instruments in the kitchen (hereinafter collectively called “kitchen inside and the like") and denatured by the action of heat or oxygen in air usually comprises a surfactant, a solvent and an alkali agent.
  • the surfactant/solvent/alkali agent-base cleaner uses an inorganic alkali salt such as sodium hydroxide, potassium hydroxide or sodium silicate, or an amine as the alkali agent in combination with the surfactant and the solvent.
  • the solvent predominantly used is a terpene-base or alkylene glycol-base solvent.
  • the cleaning composition of the present invention has a purpose of removing the grease stain adhering to home kitchen and kitchen goods and is not limited to the use in business to remove the grease stain in the kitchen inside and the like.
  • a cleaning composition comprising (1) N-methyl-2-pyrrolidone, (2) an alkali agent, (3) a surfactant and (4) water is known as an attempt to increase the detergency for the denatured grease stain (see, Japanese Unexamined Patent Publication (Kokai) No. 9-151395), though this is different from the present invention.
  • the N-methylol-2-pyrrolidone has hitherto been used as a scale removing agent or degreasing cleaner of a chemical plant and is used in the above-described cleaner composition in place of a conventional solvent.
  • the concentrated cleaner generally has a composition mainly comprising sodium hydroxide or sodium silicate as an alkali agent and using a water-soluble solvent and a surfactant in combination.
  • the concentrated cleaner can be usually used after diluting it to from 10 to 100 times.
  • the stock solution is predominantly diluted to at most about 20 times on use.
  • detergency satisfactorily strong for the persistent denatured grease stain has not yet been attained.
  • the object of the present invention is to provide a concentrated cleaner composition suitable particularly for the business use, which can overcome the above-described problems of conventional cleaners and exert strong detergency for the oxidized grease stain or persistent denatured grease stain adhering to the surface of floor, wall and cooking instruments in the kitchen even when it is diluted on use at a high dilution magnification of at least 20 times or more.
  • the concentrated cleaner composition of the present invention comprises the waterinsoluble organic solvent in an amount of from 5 to 50 wt%, the amines in an amount of from 5 to 50 wt% and the nonionic amine oxide-based surfactant as an aqueous solution thereof in an amount of from 20 to 90 wt%.
  • the first component a) is a water-insoluble organic solvent.
  • the water-insoluble organic solvent works for dissolving the grease stain and increasing the detergency.
  • This organic solvent is "water-insoluble” and therefore, it is particularly effective in improving the affinity for grease.
  • water-insoluble as used in the present invention means a property such that when a certain material (solute) is mixed with pure water at room temperature under the atmospheric condition and tried to dissolve therein, the degree of the dissolution of the solute, namely, the solubility is 20% or less.
  • the water-insoluble organic solvent is not particularly limited as long as it can satisfy the requirement in the definition of "water-insoluble” and substantially dissolve a saturated or unsaturated fatty acid, however, preferred examples thereof include diphenyl ether, 2-ethyl-1-hexanol, 2-ethylhexane-1,3-diol, phenyl methyl carbitol, phenyl glycol ethers, benzyl alcohol, 2-octanol, n-octanol, decanol, undecanol and dodecanol.
  • benzyl alcohol, phenyl glycol ethers and phenyl methyl carbitol can be advantageously used because of their high detergency, good affinity for an amine used in combination and as a result, good compatibility, and excellent solubility. If the water-insoluble organic solvent is not used and the concentrated cleaner composition of the present invention is constructed by an amine and an amine oxide-base surfactant, the cleaner composition is extremely reduced in the detergency.
  • the water-insoluble organic solvent is preferably used in an amount of from 5 to 50 wt% (based on the total weight of the cleaner composition), more preferably from 20 to 45 wt%. If the amount of the water-insoluble organic solvent used is less than 5 wt%, the cleaner composition is reduced in the detergency and not suitable for use in removing the oxidized grease stain or persistent denatured grease stain, whereas if it exceeds 50 wt%, the cleaner composition can be difficultly formed into a uniform solution.
  • the second component b) is amines.
  • Amines dissolve the grease stain and the detergency is improved by the addition of a small amount of an amine.
  • amines act as a "degreasing agent".
  • Amines which can be used include aliphatic or aromatic primary amines which have been hitherto generally used as a degreasing agent. Examples of amines which can be advantageously used include monoethanolamine, diethanolamine, triethanolamine, propanolamine, ethylamine, benzylamine, butylisopropanolamine, N-( ⁇ -aminoethyl)ethanolamine.
  • N-methylmonoethanolamine, N-ethylmonoethanolamine, N-butylmonoethanolamine, N-methyldiethanolamine and N-butyldiethanolamine are preferred because it can be used as a solvent capable of dissolving saturated or unsaturated fatty acids.
  • amines used in an amount of 20 wt% or more are classified as a "poisonous substance outside drugs" provided in the Poisonous Substance Regulation Law and an amine other than those described above is preferably added for the supplementation.
  • Amines are preferably used in an amount of from 10 to 45 wt% (based on the total weight of the cleaner composition). If the amount of amines used is less than 10 wt%, the cleaner composition is reduced in the detergency and not suitable for removing the oxidized grease stain or persistent denatured grease stain, whereas if it exceeds 45 wt%, the detergency is improved but the safety is impaired. If amines are not used and the concentrated cleaner composition of the present invention is constructed by a water-insoluble organic solvent and an amine oxide-based surfactant, the water-insoluble organic solvent cannot be solubilized.
  • the third component c) is a nonionic amine oxide-based surfactant.
  • the amine oxide-based surfactant improves an washing power and at the same time can act as a solubilizing agent of the water-insoluble organic solvent.
  • examples of amine oxide-based surfactants preferred in practicing the present invention include laurylamine oxide, decylamine oxide, myristylamine oxide, cetylamine oxide and isoalkylamine oxide (CAS: 151151-28-9), however, the present invention is by no means limited thereto.
  • isoalkylamine oxide is preferably used.
  • laurylamine oxide is preferably used.
  • the amine oxide-based surfactant in usual is preferably used in an amount of from 20 to 90 wt% (based on the total weight of the cleaner composition).
  • This surfactant may be used as a stock solution but preferably used in the form of an aqueous solution.
  • the aqueous solution of the surfactant may be used in various concentrations, however, it is preferably used in the form of a 30% aqueous solution which is easily available on the market. In the case of using a 30% aqueous solution, the amine oxide-based surfactant is suitably used in an amount of from 20 to 80 wt%.
  • the cleaner composition is reduced in the detergency and not suitable for removing the oxidized grease stain or persistent denatured grease stain, whereas even if the surfactant is used in excess of 80 wt%, the effect cannot surpass the effect achieved with the addition of the surfactant in an amount of 80 wt%.
  • the main components a), b) and c) may be used individually or if desired, two or more compounds may be used in combination.
  • the concentrated cleaner composition of the present invention may contain additives commonly used in the field of the cleaner composition.
  • suitable additives include another surfactant, an inorganic alkali salt, a thickener, an abrasive, an antimicrobial, a coloring material (e.g., dye) and a perfume.
  • suitable additives include another surfactant, an inorganic alkali salt, a thickener, an abrasive, an antimicrobial, a coloring material (e.g., dye) and a perfume.
  • an inorganic alkali salt is effective for improving the detergency.
  • suitable inorganic alkali salts include sodium hydroxide, potassium hydroxide and sodium silicate. The alkali salt is usually added in an amount of from 0.1 to 5 wt%.
  • the concentrated cleaner composition of the present invention can be prepared by blending the above-described components in a usual manner. All components may be mixed at once or the components may be blended in several installments, though it may be widely varied depending on the factors such as the kind and use amount of the components.
  • the oxidized grease stain or persistent denatured grease stain adhering to the surface of floor, wall and cooking instruments in the kitchen can be effectively washed and removed.
  • the stock solution may be diluted to from 1 to 50 times, and for washing not so persistent normal grease stain, the stock solution may be diluted to from 50 to 100 times.
  • Example 1 a concentrated cleaner composition (Example of the present invention) having the composition shown in Table 1 below was prepared. The components were blended by batchwise mixing all amounts and stirring the mixture.
  • the concentrated cleaner compositions obtained were subjected to the following detergency test and evaluated on the detergency for the denatured grease stain. The results are shown in Table 1 below.
  • a commercially available edible oil for fries was charged into an empty pudding container (50 ml) and heated in an oven at 250°C over 5 hours to cause thermal denaturation.
  • the edible oil after the thermal denaturation was coated on a stainless steel plate having a size of 25 mm x 75 mm to have a coverage of 100 mg ⁇ 10 mg and this coating was used as a test piece (model stain).
  • Each concentrated cleaner composition was diluted to have a ratio in dilution (%) shown in Table 1 and in the cleaner solution obtained, the test piece was dipped over 30 minutes. The difference in the weight between before and after the dipping of each test piece was determined and the removal percentage of the denatured oil was produced and used as the washing ratio (%).
  • Examples 1 to 6 The procedure of Examples 1 to 6 was repeated except for preparing comparative concentrated cleaner compositions each having the composition shown in Table 1 below. More specifically, the concentrated cleaner compositions were prepared not using an amine in Comparative Example 7, not using an amine oxide-base surfactant in Comparative Example 8, and not using a water-insoluble organic solvent in Comparative Examples 9 and 10. In Comparative Examples 11 and 12, a sodium silicate-base concentrated cleaner for business use, which is commercially available from Company A, was used. The concentrated cleaner compositions each was evaluated on the detergency for the denatured grease stain in the same manner as in Examples 1 to 6. The results obtained are shown in Table 1 below.
