Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to various surfaces, in particular glass, painted surfaces (pa).
int-work), porcelain tiles, vinyl floors, chrome plates, marble and plastic laminates for the purpose of being suitable for use undiluted for cleaning fixed surfaces. The present invention aims to eliminate the need for rinsing.

General purpose conventional cleaning products intended for home use are usually cleaned effectively, but require rinsing or subsequent buffing for good results, especially on bright surfaces such as glass or chrome. Is. Current products, especially for cleaning windows, often recommend using a limited amount of the product and then rubbing and drying with a dry cloth to prevent streaks and stains. In practice, it is often used above the recommended level and is difficult to rub until it is completely dry. Of course, as the cleaning work progresses,
The cloth gets wet with the dirty product liquid absorbed. These often leave visible deposits on windows or mirrors.

In at least a preferred form, the present invention aims to provide a product which is capable of producing a good cleaning surface even when used at high levels above the required amount and / or above the incompletely removable amount. The present invention aims at leaving no visible residue on the surface after washing.

According to the invention, with water, a boiling point of 200 ° C or less at atmospheric pressure or 20 ° C
And an alkyl group having an evaporation rate of 0.01 times or more that of n-butyl acetate and preferably having 1 to 5 carbon atoms together with at least one hydroxyl group (eg, propyl,
Butyl or pentyl groups, etc.) in a solvent system optionally containing up to 10% by weight of ammonia or 0.1-10% by weight of an alkanolamine having a boiling point of 200 ° C. or less at atmospheric pressure and a cation having a molecular weight of 5,000 or more. An aqueous cleaning composition comprising 0.001 to 0.5% by weight of a polymer, more preferably 0.001 to 0.05% by weight, which is substantially free of inorganic electrolyte and does not boil below 200 ° C. at a surfactant and atmospheric pressure. Up to 0.5% by weight of any of the materials of. All the above percentages are
Based on the entire composition.

The total amount of surfactant and any other substance that does not boil below 200 ° C. at atmospheric pressure preferably does not exceed 0.2% by weight, based on the total composition.

The organic solvent is at least 0.05% by weight, preferably 0.5
It is preferably blended in an amount of up to 10% by weight.

The compositions of the present invention contain a very large proportion of components that are sufficiently volatile to evaporate these residues from the surface. The property of boiling below 200 ° C. under normal atmospheric pressure (760 mmHg) indicates that it is suitable for volatility.

Another method of assessing volatility by comparing it with the evaporation rate of n-butyl acetate is the method of determining volatility that is frequently used in the solvent industry. When the composition is applied, for example with a cloth, most of the stains that can dissolve with the composition can be removed by the cloth used for application and / or the second cloth used subsequently. Most of the residue left on the surface will evaporate. Polar organic compounds with boiling points above 200 ° C. are generally not sufficiently volatile in this case.
Therefore, its boiling level is preferably very low as described above.

The preferred and basic components are described below.

Any organic solvent is preferably sufficiently water soluble to obtain a single phase solvent system. However, it is also possible to use a poorly water-soluble solvent and to include an excess of a sufficient amount of organic solvent to form a separate phase. These solvents can be dispersed as emulsions or distributed throughout the product by shaking the container before use.

The types of organic solvents include hydroxyl functional groups and C ₁ ~
C _5, preferably solvents, such as including both the alkyl group is a C ₃ -C ₅ alkyl. In this latter case, of course, since the solvent comprises a combination of hydrophilic and lipophilic functional groups, the preferred solvent helps to lower the surface tension as well as solubilize oily soils.

C ₃ -C ₅ alkyl groups, bonded via binds to directly hydroxyl as in the case of aliphatic alcohols or a carbon atom, a linking group containing both an atom other than carbon or hydrogen (usually oxygen) You may have.

Suitable organic solvents have the following structure: R—X—OH, where R is C ₁ -C ₅ alkyl, X is a covalent bond or —OCH ₂ CH ₂ — Or -OC ₂ H ₄ OC ₂ H ₄ -or -OC ₃ H ₆ OC ₃ H _6- ,
However, a boiling point of 200 ° C. or lower is an essential condition in all cases].

Suitable solvents having the formula defined above include methanol, ethanol and various isomers of propanol, butanol and pentanol, 2-propoxyethanol, 2-butoxyethanol, 2-pentoxyethanol,
1-propoxypropan-2-ol and 1-butoxypropan-2-ol are mentioned.

Examples of the low water-soluble solvent forming the multiphase include paraffin, olefin, terpene, alkylbenzene and the like, each of which has a boiling point of 200 ° C. or less as an essential condition.

The ammonia or alkanolamine acts to make the composition alkaline effective in cleaning performance. Alkanolamines are preferred over ammonia. Because its hydroxy functional group acts to promote water solubility and the amino group contributes to the solubilization of polar greasy soil.

Alkanolamines that meet the essential requirement of a boiling point of 200 ° C. or lower usually have the following structural formula: [Wherein R ¹ is hydroxyalkyl and R ² and R ³ are (independently) hydrogen or an alkyl group].

The number of carbon atoms in the R ¹ , R ² and R ³ groups is limited by the essential requirement that the boiling point not exceed 200 ° C. R ¹ , R ² and R ³
The total number of carbon atoms contained in the group is generally 4 or less.

Monoethanolamine is the preferred compound. Others include 2-amino-2-methylpropanol, 2-aminopropanol, n-propanolamine, 2-amino-1-butanol, N-methylethanolamine and N, N-dimethylethanolamine.

The amount of alkanolamine is up to 10% by weight of the composition. However, it is preferred that the amount is less than or equal to 5% by weight. This is because there is no added value for the extra cost even if it exceeds 5% by weight. The amount of alkanolamine is preferably at least 0.5% by weight.

The cationic polymer promotes the performance of the composition and removes particulate soil. Without being bound by Applicant's hypothesis on how it works, a polymer can be used to remove particulate soil without the adverse effects (eg, binding of soil particles to the surface) that result in excessive aggregation and interference with detergents. It is believed that the particles can be agglomerated. It is believed that the resulting large particles can then be more easily removed by the cloth used to wipe the wash surface.

Various cationic polymers can be used. The molecular weight of the polymer is at least 10,000, preferably at least
It is preferably 50,000 or at least 100,000.
When adding the polymer to the composition, at least 1,000,
It may have a high molecular weight of 000 or at least 5,000,000 to 20,000,000 or more. However, some cleavage of the polymer chain length may occur in the composition.

Cationic polymers usually consist of polymer chains without cationic character which carry cationic substituents.

Certain cationic polymers may interact with anionic or amphoteric surfactants, reducing the effectiveness of both. Applicants have identified anionic surfactants as surfactants.
When compounded within the limit of 0.5% by weight, it is advisable to use a cationic polymer that is a hydrophilic polymer chain (such as a polysaccharide or polyacrylamide) and has 50 (mol)% or less of cationic substituents on this chain. It was found to be preferable. It is preferred that less than 35%, preferably less than 20%, more preferably less than 10% of the repeating units in the polymer chain have cationic substituents. A wide range of cationic polymers can be used, including cationic polymers based on lipophilic polymer chains, such as polyethylene or polymethylene, when no anionic surfactant is incorporated.

Examples of cationic polymers that may be used in the compositions of the present invention include:

a) Copolymerization with acrylamide or methacrylamide, eg dimethylamino-ethylmethacrylate (then quaternized with dimethylsulfate) or N, N-dimethyl 3,5-
Polyacrylamide and polymethacrylamide prepared by copolymerization with methylenepiperidinium chloride. Alternatively, an alkaline hypochlorite or amine and formaldehyde treated poly (meth) acrylic acid provides a cationically substituted polyacrylamide.

b) Starch treated with, for example, (4-chlorobutene-2) -trimethylammonium chloride, β-diethylaminochloroethyl chloride, dimethylaminoethyl methacrylate or 2,3-epoxypropyltrimethylammonium chloride. In particular, cationized guar gum and hydroxyethyl cellulose are useful.

c) N, N-Dimethyl-3,5-methylenepiperidinium chloride or homopolymer of ethyleneimine. Polyethyleneimines and polyamines exhibit useful cationic properties up to pH 9-11, which is preferred for the present invention.

The compositions of the present invention may conveniently contain some detergent actives. However, for purposes of use without rinsing, the inorganic electrolyte is substantially unincorporated and the detergent activator should not exceed a maximum of 0.5% by weight of the composition, for example 0.01-0.5% by weight, preferably 0.2% by weight. Limited to.

Detergent activators, which can be chosen from the customary classes, ie anionic, nonionic, cationic and amphoteric detergents and mixtures thereof, are used. Anionic detergent activators are preferred due to their good detergency, but as mentioned above some cationic polymers cannot be used with anionic detergents. Nonionic detergent activators are preferred in this case. Typically, anionic, cationic and amphoteric detergent activators contain an alkyl group of 8 to 22 carbon atoms or an aromatic alkyl group of 6 to 14 carbon atoms and a charged head group in the alkyl portion.

Examples of anionic detergent-active agents include C ₁₀ -C ₁₂ sodium alkyl benzene sulfonate and C ₁₂ -C ₁₅ synthetic alcohols 3E0 sodium sulfate. It may be a C ₁₀ -C ₁₆ 2 alkane sulfonate.

Nonionic detergent actives may be prepared by the condensation of an alkylene oxide group, which is hydrophilic in nature, with an organic lipophilic compound, which may be an aliphatic or aromatic alkyl in nature. The length of the hydrophilic or polyoxyalkylene group that is condensed with any particular lipophilic group is adjusted to give a water-soluble compound that has the desired degree of balance between the hydrophilic and lipophilic components. Can be done. As a specific example,
Condensates of ethylene oxide with aliphatic alcohols having 8 to 22 carbon atoms in a straight or branched chain structure (for example,
Condensation of coconut oil ethylene oxide having 2 to 15 mol of ethylene oxide per mol of coconut alcohol), condensation of synthetic primary or secondary alcohol having 8 to 15 carbon atoms with 3 to 12 mol of ethylene oxide per mol of synthetic alcohol. Thing and its alkyl group have 6 to 12 carbon atoms
And a condensate of 5 to 25 moles of ethylene oxide per mole of alkylphenol.

Examples of nonionic surfactants are reaction products of ethylenediamine and propylene oxide with ethylene oxide, condensates containing 40 to 80% by weight of polyoxyethylene groups and having a molecular weight of 5,000 to 11,000, and ethylene oxide and propylene oxide. Block copolymers may be mentioned.

Nonionic detergent-active agent, C ₈ -C ₂₂ alkyl group and a polar head group (those provided by alkylene oxide residues or others) may be a compound containing. Examples of these include the formula: RR ¹ R ¹ NO where R is an alkyl group of 8 to 18 carbon atoms,
R ¹ are each methyl, tertiary amine oxides of a is] ethyl or hydroxyethyl groups, for example, dimethyl dodecylamine oxide; etherified with at least one C ₈ -C ₂₂ alkyl group or at least one C ₈ ~ Examples include glycosides or polyglycosides esterified with C ₂₂ fatty acyl groups; fatty acid alkylolamides; and alkylene oxide condensates of fatty acid alkylolamides.

Mixtures of two or more nonionic detergent actives as well as nonionic and anionic detergent actives may also be used.

The non-volatile components of the compositions of the present invention will be any detergent actives and cationic polymers (if used), along with a portion of any perfume (if used). A rough practical guideline is that half of the usual perfumes will be non-volatile. Such non-volatile components are highly desirable at 0.5% by weight or less of the composition,
0.2% by weight or less is preferable.

The composition of the present invention may be prepared by simply mixing its constituents with distilled or deionized water, such as by mixing in a mixing vessel equipped with a stirrer.

The fringes on a high-gloss, black porcelain tile wiped with a standard amount of formulation and wiped with a sponge cloth were subjectively evaluated. The liquid film was left to evaporate before evaluation. The high-gloss black tile is a very discriminating surface for the determination of streaks and product residues.

Efficacy was evaluated using porcelain floor tiles soiled with fat-based stains or particle-based stains. The soiled tiles were prepared by combining the solvent solution and suspension to spray the soil components and then rubbing the soil onto the surface so that the soil was a uniform coating that was not easily wiped with a dry cloth.

To evaluate cleaning performance, 3 drops of the composition were applied to the soiled surface, soaked for 10 seconds and then wiped with a dry tissue.

The fat-based stain consisted of 5 parts kaolin, 0.2 parts carbon black, 19 parts glycerol trioleate and 1 part oleic acid. This is a model for kitchen and bathroom stains. The particle-based stain consisted of 8 parts of illite clay, 0.1 part of carbon black and 2 parts of glycerol trioleate. This is a model for dirt found on floors and windows.

The results are shown by ranking the performance.

1 represents the standard achieved by Example 1, 1+ represents a rather good result, 1- represents a slightly inferior result, 2, 3 and 4 represent inferior detergency in numerical order. . Therefore, the grades are as follows:

Best 1 + 1 1 2 3 Worst 4 Results: From these results, it can be seen that the product of the present invention exhibits good detergency by leaving very little product residue on the cleaned surface.

The composition of Example 1 and similar compositions with and without various cationic polymers were used to demonstrate the effectiveness of the cationic polymers in removing particulate soil.

A 30 cm × 30 cm glass mirror was thoroughly washed and its reflectance was measured.

A dirty ethanol solution consisting of 8 parts of iritit-type clay and 0.1 part of carbon black was lightly and uniformly sprayed on the mirror. The reflectance was measured again. One half of the mirror (15cm x 30
cm) was washed with the composition of the example and the other half on one side was washed with the control window cleaning product. Each half was washed by hanging 1/2 ml of the composition on the soiled surface and wiping the area 32 times with a non-woven viscose (approximately 75 g.sm, 12 × 15 cm). After leaving for 1 minute to dry, the reflectance of the surface of the washed mirror was measured again. If the reflectivity of a perfectly clean mirror is known, the% loss due to the initial and residual stain coverage can be calculated.

The results were as follows.

In all of these cationic polymers, as compared to using compositions without cationic polymers,
Substantially improved results have been obtained. Glycerol trioleate 2 which is a particle-based stain as described above
Similar results were found for stains including parts.
