Detergents and cleaning agents containing acetals as organic solvents

Organic, water-soluble, partially water-soluble or water-insoluble

Solvents are used in a variety of detergents and cleaners.

These include both products for household use, as well

Products for commercial, industrial or institutional use.

Solvent-based detergents and cleaners used in household or in the

Commercial uses are in particular those which are present in liquid, in gel or in paste form. These include in particular

Liquid detergents, washing pastes, washing gels, pre-wash sprays, spot sprays,

Washing booster, stain-free, softener, all-purpose cleaner,

Hand dishwashing detergents, machine-washing liquid dishwashing detergents,

Dishwashing rinse aid, oven cleaner, grill cleaner,

Glass cleaner, stainless steel cleaner, bathroom cleaner, kitchen cleaner, cold cleaner

(Engine cleaner), tar remover, insect remover, car drying agent for

Car washes, car window cleaner, Wachsfilmentfemer, rim cleaner,

Spray Extraction Cleaner, Brush Cleaner, Polishing Pastes and Plastic Cleaner.

However, depending on the volatility of the organic solvents, they can also be used in powder detergents and cleaners. The integration into a waxy matrix is also possible.

Examples of the use of organic solvents in powder or tablet detergents are e.g. such as machine dishwashing detergents

Find use.

As organic, water-soluble, partially water-soluble or even water-insoluble solvents may be used in detergents and cleaners, e.g. the following are used:

Monohydric alcohols, such as ethanol, n-propanol, iso-propanol, n-, iso- and part.

Butanol.

Two or more polyhydric alcohols such as ethylene glycol, 1,2-propylene glycol, 1, 3-propylene glycol, butylene glycol or glycerin.

Ethers, in particular glycol ethers, which are obtained by the reaction of

Ci-C ₆ -alcohols or of phenol with one or more moles of a

Alkylene oxide, in particular with ethylene oxide or propylene oxide. examples for

Glycol ethers are mono-, di- and tri-propylene glycol monomethyl ethers,

Propylene glycol phenyl ether, mono- and di-ethylene glycol n-butyl ether,

Ethylene glycol phenyl ether.

Ketones such as e.g. Methyl isopropyl ketone and butanone-2.

Esters, e.g. Propyl acetate.

Oligo- and polyalkylene glycols such as e.g. Diethylene glycol, dibutylene glycol or low molecular weight polyethylene glycol, e.g. with the molar masses 300 and 400

(PEG 300 and PEG 400).

Terpenes, e.g. Orange terpene. n- and iso-alkanes of different chain length, with different

Degree of branching or with specific boiling ranges, paraffin oil, kerosene,

White spirit.

Nitrogen-containing solvents such as e.g. N-methylpyrrolidone.

The solvents can perform very different functions in the formulations. These include, for example, the reinforcement of the cleaning performance, in particular with regard to greasy and oily soiling, caused by, for example, food, (machine) oil, shoe polish, ointments, vaseline and cosmetics. In the case of specific stain remover, the removal of very special soiling is to be made possible by, for example, adhesives, chewing gum, nail polish, floor wax, resins, waxes and tar. Furthermore, the stabilization of formulations, an action as solubilizers, in particular also for highly concentrated or polymer-containing formulations, the improvement in the low-temperature stability and the "clarification" of opaque and slightly cloudy formulations should be mentioned. Examples of solvent-based washing, cleaning and care products are:

liquid detergent

Liquid laundry detergents may be e.g. Ethanol or 1, 2-propanediol as a solubilizer included.

spotless

For example, stain-less, also called "stain-water", may be composed exclusively of aliphatic n- and / or iso-alkanes, in which case it is also referred to as "petroleum ether." In addition, however, other solvents such as alcohols may also be included.

Softener / laundry conditioners Table 5: Solvent-based softener for textiles

Stainless steel cleaner for the household (for example for sinks)

These are in the household, e.g. used for cleaning sinks. to

To remove stubborn stains they contain abrasive substances, e.g.

Poliertonerde. Table 15: Solvent-based stainless steel cleaner for the household

bathroom cleaner

Bathroom cleaners are used e.g. for removing limescale or lime soap residue from sanitary objects, tiles and fittings. You can also include organic solvents.

In addition to the classic washing and cleaning agents for the household or cars, there are other solvent-based cleaners with very different applications such as: Table 24: Spray Extraction Control

Table 25: Brush Cleaner

Table 26: Polishing pastes for chrome surfaces

The listed formulations serve exclusively to prove the use of organic solvents in detergents and cleaners. However, they do not constitute recommendations and would have to be examined by the user for their suitability for use in a readjustment.

The prior art solvents each have their own specifics

Disadvantages.

For example, the flash point of ethanol or isopropanol is very low at 12 ^° C., which also limits the use concentrations in detergents and cleaners.

In addition, the fat-solubility of these alcohols is limited.

Although glycol ethers have a high flash point, which is, for example for dipropylene glycol monomethyl ether at about 8O ⁰ C, but here is the dissolving power for

Fats and oils limited.

On the other hand, aliphatic hydrocarbons, which due to their lipophilic properties have a very good dissolving power for greasy and oily stains, can only be incorporated to a limited extent in the aqueous surfactant systems.

The object of the present invention is to provide organic solvents which have a very good dissolving power for fats and oils and at the same time a sufficient polarity, so that the

Incorporation into aqueous preparations in wide concentration ranges is easily possible.

EP 1 184 448 describes aqueous liquids containing an acetal and a surfactant. These liquids, in contrast to the washing and cleaning agents according to the invention described below, are present only in the form of microemulsions or as liquid crystalline phases. In addition, the acetals in EP 1 184 448 only serve as solubilizers. The actual cleaning performance is provided by conventional surfactants.

It has now surprisingly been found that compounds of the formula (1) alone have a very good cleaning power or solubility for greasy and oily stains and at the same time very good in incorporate aqueous formulations. At the same time, however, the compounds of the formula (1) can also be used in anhydrous formulations as a substitute for, for example, aliphatic hydrocarbons. In addition, they have a favorable toxicological and ecological profile of properties.

The invention thus provides detergents and cleaners containing as solvents the compounds of the formula (1),

in which

A is (CH ₂ ) _a or phenylene,

R ¹ , R ² , R ³ and R ^{4 are} identical or independently of one another Ci to C ₂₂ -n- and / or iso-

Alkyl, C ₅ or C ₆ cycloalkyl, phenyl-d ^ -alkyl, Ci-C ₁₃ alkyl-phenyl or

May be phenyl and a is an integer from 0 to 6.

R ¹ , R ² , R ³ and R ^{4 are} identical or independently of one another Ci to Ci ₃ - n- and / or iso-alkyl, C ₅ or Cβ-cycloalkyl, phenyl-Ci-C ₂ ~ alkyl-, Ci-Cg-alkyl-phenyl or phenyl and a is preferably 0 to 2.

Particularly preferably, R ¹ , R ² , R ³ and R ^{4 are the} same or independently

Ci to C ₈ -n- and / or iso-alkyl, cyclohexyl, benzyl or phenyl and a is preferably 0 or 1.

Most preferably, R ¹ , R ² , R ³ and R ^{4 are the} same or independently of one another Ci to C ₆ -n- and / or iso-alkyl and a is 0.

Examples of the radicals R 1 to R 4 are, for example: methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, sec-butyl, tert-butyl, n-amyl iso-amyl, tert-amyl, neopentyl, cyclopentyl, n-hexyl, iso-hexyl, cyclohexyl, octyl, decyl, isotridecyl, phenyl, benzyl, phenylethyl, nonylphenyl. The compounds of the general formula (1) are acetals. Acetals are generally obtained by the reaction of aldehydes with 2 moles of an alcohol per carbonyl group in the presence of catalysts such as dry hydrogen chloride.

For the synthesis of compounds of formula (1) dialdehydes must be used. Preferred dialdehydes for the synthesis of compounds of formula (1) are glyoxal, malondialdehyde (1,3-propanedial, 1,3-propanedialeddehyde), 1,4-butanedial and terephthalaldehyde. A most preferred dialdehyde is glyoxal. A particularly preferred compound for the described application is tetramethoxyethane (2).

(2)

The invention also provides the use of the compounds of the formula (1) or (2) for cleaning and loosening stains from solid surfaces. Accordingly, the invention also provides a process for cleaning solid surfaces, which comprises treating the solid surfaces with an agent containing a compound of formula (1). Solid surfaces which can be cleaned with the acetals of the formula (1) or (2) are especially textile fibers but also metallic or ceramic surfaces, glass, porcelain or plastics.

The solvents of formula (1) and especially tetramethoxyethane (2) can be used in liquid detergents, washing pastes, washing gels, prewash sprays, washing intensifiers, spot sprays, spotless, fabric softeners, all-purpose cleaners, hand dishwashing detergents, automatic dishwashing detergents, dishwashing rinse aids, oven cleaners, Grill cleaners, glass cleaners, stainless steel cleaners, bathroom cleaners, kitchen cleaners, carpet cleaners, cold cleaners (engine cleaners), tar removers, insect removers, auto dryers for Car washes, car window cleaners, car shampoos, wax film removers, rim cleaners, spray extraction cleaners, brush cleaners, polishing pastes and plastic cleaners.

Particularly preferred here is the use in prewash sprays, laundry detergents, stain sprays and bleach for textiles, liquid detergents, also in all-purpose cleaners, dishwashing detergents for dishwashing, dishwasher rinse aid, kitchen cleaners, glass cleaners, cold cleaners (engine cleaners), car drying agents for car washes, automotive Windscreen cleaners, car shampoos and in plastic cleaners.

In the event that the ^" acetals of formula (1) have a low volatility, which can be achieved by the choice of the radicals R1 to R4, for example by the choice of long Alkyireste, these can also be used in solid detergents and cleaners, which may be present, for example, as a powder, granules, pellets, wax, as a wash or in the form of tablets.

In particular, the acetals of formula (1) can be successfully used in those washing, cleaning and care products, as described initially in Tables 1 to 26, which is incorporated herein by reference. The acetals of the formula (1) can completely or partially replace the organic solvents specified therein in these agents.

The amount of acetal of the formula (1) in the detergents and cleaners according to the invention can vary widely and depends on the specific composition of such detergents and cleaners in each particular case.

In the following, general information on the composition of the most important detergents and cleaners is given.

Examples:

Example 1: Dissolving power of tetramethoxyethane for oil and grease dirt

The removal of a paraffin oil stain from cotton / polyester fabric with tetramethoxyethane compared to other solvents was investigated. For this purpose, the standard test cloth wfk 2OA the laundry research institute Krefeld was soiled with paraffin oil, which was dyed with the fat-soluble dye Sudan red. To simulate a stain spray or stain remover, the test fabric was then placed in tetramethoxyethane or in the reference solvents for 10 min. Subsequently, the test fabric was removed and solvent-wet with an aqueous wash of the standard detergent IEC-A (phosphate-free detergent of the Laundry Research Institute Krefeld) for 30 min. At 40 ⁰ C washed. The test fabric was dried after rinsing with clear water and then determined as a measure of the stain removal whiteness. The higher the whiteness, the better the red oil stain was washed out.

Table 1: Removal of paraffin oil from cotton / polyester fabric wfk 2OA by tetramethoxyethane compared to reference solvents. Quantification about the whiteness.

In addition to the whiteness achieved (remission), the color difference dE of the soiled and then washed fabric was determined to be the non-soiled tissue. The lower the color difference dE, the less residue of the colored paraffin oil is present on the fabric. Ideally dE is equal to zero.
