EP2480646B1 - Unperfumed cleaning agent - Google Patents

Description

The invention relates to a perfume-free aqueous cleaning agent for hard surfaces and / or textiles containing tall oil soap and at least one C ₁ -C ₆ -alcohol.

All-purpose cleaners have long been used in many households for cleaning hard surfaces, usually in diluted form. They have proven themselves in the removal of a variety of stains. Also means of stain removal and stain pretreatment on textiles are often used, mostly in concentrated form.

It is desirable and now also complies with legal regulations and standards that the use of detergents and cleaners has the least negative impact on the environment. For example, the EU Detergents Regulation requires that for each surfactant used today in detergents, primary degradation should be at least 80% and full biodegradation (after 28 days) at least 60%. However, the petrochemical-based surfactants frequently used because of their good cleaning performance, for example linear alkylbenzenesulfonates (LAS), are only poorly degradable anaerobically. It would therefore be advantageous to find formulations whose surfactants and also other active substances are completely prepared on the basis of renewable raw materials.

The challenge is not to sacrifice any cleaning performance. Surfactants based on renewable raw materials are well known, but often do not have sufficient cleaning performance, so they must be combined with surfactants on a petrochemical basis in the rule.

Furthermore, the other ingredients, such as solvents, fragrances or auxiliaries, are often not available on the basis of renewable resources and also poorly biodegradable. In particular, the fragrances, the components of which also have an allergenic potential at higher concentrations, are considered to be problematic.

Therefore, there has been a desire for a hard surface cleaner based on a higher proportion of renewable resources yet having a good cleaning performance; This remedy should also be free from perfume oils and other fragrances and have a pleasant smell.

US 7396808 B1 (The Clorox Company) describes hard surface cleaners consisting essentially of 0.5 to 5 weight percent alkyl polyglucoside, 0.5 to 5 weight percent ethanol, 0.05 to 1 weight percent glycerol, 0.05 to 0.4 wt .-% lemon oil or d-limonene and water, less than 0.2 wt.% Builder and optionally colorants and preservatives exist. It should be to cleaners of natural ingredients with high cleaning performance. However, the fragrances contained are not readily biodegradable and can also act as allergens. US 5080831 . US 4477361 and EP 0375474 describe detergents containing tall oil soaps.

Surprisingly, it has now been found that a cleanser which contains tall oil soap and at least one C ₁ -C ₆ -alcohol has a scent which is perceived as pleasant even without the use of perfume oils and other fragrances. In addition, it also has a good cleaning performance when using surfactants purely on a oleochemical basis.

The subject of this application is accordingly a perfume-free aqueous cleaning agent for hard surfaces and / or textiles, which 0.1 to 15 wt.% Tallölseife at least one C ₁ -C ₆ alcohol, and 0.1 to 12 wt.% Of at least one surfactant contains the fat-chemical base, wherein the at least one surfactant is selected on the basis of oleochemical base from the group comprising alkylpolyglycosides, fatty alcohol alkoxylates, Alkylamidoalkylamine, fatty alcohol ether sulfates and mixtures thereof.

The cleaning agent is suitable both for diluted application and for direct application to the surface to be cleaned. For this purpose, preferably a spray dispenser is used, preferably a spray dispenser with foam nozzle.

A further subject of this application is accordingly a product comprising a cleaning agent according to the invention and a spray dispenser, in particular a cleaning agent according to the invention and a spray dispenser with foam nozzle.

The cleaning agent according to the invention is preferably used for cleaning hard surfaces and / or textiles in a corresponding cleaning process. A further subject of the application is therefore the use of a cleaning agent according to the invention for cleaning hard surfaces. Yet another subject of this application is a method for cleaning hard surfaces, wherein in a process step, the cleaning agent according to the invention is applied to the surface to be cleaned. Another object of the invention is the use of a cleaning agent according to the invention for stain removal and / or for spot pretreatment on textiles, in particular for greasy stains.

fatty alcohol

Also suitable as surfactants based on oleochemicals are fatty alcohol ether sulfates (C ₈ -C ₁₈ -alkyl polyglycol ether sulfates).

Fatty alcohol ether sulfates are products of sulfation reactions on alkoxylated alcohols. The person skilled in the art generally understands, under alkoxylated alcohols, the reaction products of alkylene oxide, preferably ethylene oxide, with alcohols, preferably in the context of the present invention, the longer-chain alcohols (fatty alcohols). As a rule, n moles of ethylene oxide and one mole of alcohol, depending on the reaction conditions, form a complex mixture of addition products of different degrees of ethoxylation.

A particularly preferred fatty alcohol ether sulfate is, for example, C _12-14 fatty alcohol ether sulfate with 2 EO.

The anionic surfactants are preferably used as sodium salts, but may also be present as other alkali metal or alkaline earth metal salts, for example magnesium salts, and in the form of ammonium or mono-, di-, tri- or tetraalkylammonium salts, in the case of the sulfonates also in the form their corresponding acid, eg dodecylbenzenesulfonic acid.

pH adjuster / alkali carrier

To regulate the pH, the agent according to the invention may also contain acids or bases or volatile alkali.

Volatile alkali; bases

The volatile alkali used is ammonia and / or alkanolamines, which may contain up to 9 C atoms in the molecule. As alkanolamines, the ethanolamines are preferred and of these in turn the monoethanolamine. The content of ammonia and / or alkanolamine is preferably 0.01 to 2 wt .-%; ammonia is particularly preferably used.
In addition, the cleaning agents according to the invention may also contain small amounts of bases. Preferred bases are selected from the group of alkali and alkaline earth metal hydroxides and carbonates, in particular the alkali metal hydroxides, of which potassium hydroxide, sodium hydroxide and mixtures thereof are particularly preferred.

Cosurfactants

The agent according to the invention may contain, in addition to the ingredients mentioned, further surface-active substances. Suitable surface-active substances for the compositions according to the invention are surfactants from the classes of anionic, nonionic, cationic and amphoteric surfactants. Preferably, surfactants with proportions of renewable raw materials are also used here.

Suitable anionic surfactants are preferably C ₈ -C ₂₀ -alkanesulfonates, C ₈ -C ₁₈ -monoalkyl sulfates and sulfosuccinic mono- and di-C ₈ -C ₁₈ -alkyl esters.

The anionic surfactants are preferably used as sodium salts, but may also be present as other alkali or alkaline earth metal salts, for example magnesium salts, and in the form of ammonium or mono-, di-, tri- or tetraalkylammonium salts, in the case of the sulfonates also in the form their corresponding acid. Examples of such surfactants are sodium cocoalkyl sulfate, sodium sec-alkanesulfonate having about 15 carbon atoms and sodium dioctylsulfosuccinate.
In a particularly preferred embodiment, however, the agent according to the invention is free of linear alkylbenzenesulfonate surfactants (LAS), which have hitherto been used frequently in cleaning agents as anionic surfactants.

Particularly suitable nonionic surfactants are C ₈ -C ₁₈ -carboxylic acid polyglycol esters having 2 to 15 EO, for example tallow fatty acid + 6-EO esters, ethoxylated fatty acid amides having 12 to 18 C atoms in the fatty acid moiety and 2 to 8 EO, for example lauric acid diethanolamide, and long-chain ones Mention is made of amine oxides having 14 to 20 carbon atoms, such as the cocoalkyldimethylamine oxide.

thickener

It may be desirable to adjust the viscosity of the agent according to the invention by adding a thickener. All viscosity regulators commonly used in detergents and cleaning agents are suitable, for example organic natural thickeners (agar-agar, carrageenan, tragacanth, gum arabic, alginates, pectins, Polyols, guar gum, locust bean gum, starch, dextrins, gelatin, casein), organic modified natural products (carboxymethyl cellulose and other cellulose ethers, hydroxyethyl and propyl cellulose and the like, gum ethers), organic fully synthetic thickeners (polyacrylic and polymethacrylic compounds, vinyl polymers, Polycarboxylic acids, polyethers, polyimines, polyamides) and inorganic thickeners (polysilicic acids, clay minerals such as montmorillonites, zeolites, silicic acids).
Preferably, however, the agent according to the invention is free of thickeners. The viscosity of the composition according to the invention is preferably 0.4 to 400 mPas (Brookfield LVDV 2+ with small sample adapter, spindle 31, 30 rpm, 20 ° C., undiluted product).

antibacterial agents

Disinfection and sanitation constitute a particular form of purification. In a corresponding particular embodiment of the invention, the cleaning agent therefore contains one or more antimicrobial agents, preferably in an amount of 0.01 to 2% by weight, preferably 0.02 to 0 , 9 wt .-%, in particular 0.05 to 0.5 wt .-%, particularly preferably 0.1 to 0.4 wt .-%, most preferably 0.3 wt .-%.
The terms disinfection, sanitation, antimicrobial action and antimicrobial agent have the usual meaning in the context of the teaching of the invention, the example of KH Wallhäußer in "Practice of Sterilization, Disinfection - Conservation: Germ Identification - Plant Hygiene" (5th edition - Stuttgart, New York: Thieme, 1995 ) is reproduced. While disinfection in the narrower sense of the medical practice means the killing of - in theory all - infectious germs, sanitation is to be understood as the greatest possible elimination of all - including the saprophytic - normally harmless to humans saprophytic - germs. Here, the extent of disinfection or sanitation depends on the antimicrobial effect of the applied agent, which decreases with decreasing content of antimicrobial agent or increasing dilution of the agent for use.
For example, antimicrobial agents from the groups of alcohols, aldehydes, antimicrobial acids or their salts, carboxylic esters, acid amides, phenols, phenol derivatives, diphenyls, diphenylalkanes, urea derivatives, oxygen, nitrogen acetals and formals, benzamidines, isothiazoles and their derivatives are suitable according to the invention Derivatives such as isothiazolines and isothiazolinones, phthalimide derivatives, pyridine derivatives, antimicrobial surface-active compounds, guanidines, antimicrobial amphoteric compounds, quinolines, 1,2-dibromo-2,4-dicyanobutane, iodo-2-propynyl-butyl-carbamate, iodine, iodophores and peroxides. Preferred antimicrobial agents are preferably selected from the group comprising ethanol, n-propanol, i-propanol, 1,3-butanediol, phenoxyethanol, 1,2-propylene glycol, glycerol, undecylenic acid, citric acid, lactic acid, benzoic acid, salicylic acid, thymol, 2- Benzyl 4-chlorophenol, 2,2'-methylenebis (6-bromo-4-chlorophenol), 2,4,4'-trichloro-2'-hydroxydiphenyl ether, N- (4-chlorophenyl) -N- ( 3,4-dichlorophenyl) urea, N, N '- (1,10-decanediyldi-1-pyridinyl-4-ylidene) bis (1-octanamine) dihydrochloride, N, N'-bis (4- Chlorophenyl) -3,12-diimino-2,4,11,13-tetraazatetradecandiimidamide, antimicrobial quaternary surface active compounds, guanidines. Preferred antimicrobial surface active quaternary compounds contain an ammonium, sulfonium, phosphonium, iodonium or arsonium group, as for example KH Wallhäußer in "Practice of Sterilization, Disinfection - Conservation: Germ Identification - Plant Hygiene" (5th edition - Stuttgart, New York: Thieme, 1995 ) describes. Furthermore, antimicrobially effective essential oils can be used, which at the same time provide for a scenting of the cleaning agent. However, particularly preferred antimicrobial agents are selected from the group comprising salicylic acid, quaternary surfactants, in particular benzalkonium chloride, peroxo compounds, in particular hydrogen peroxide, alkali metal hypochlorite and mixtures thereof.

preservatives

Preservatives may also be included in compositions of the invention. As such, essentially the substances mentioned in the antimicrobial agents can be used.

Skin protection and skin care products

The composition according to the invention may additionally contain skin protection and skin care agents. As such are all known care agents, including bisabolol, allantoin, vitamins such as panthenol, natural oils such as almond oil, plant extracts such as marigold, aloe vera, nourishing wax dispersions, nourishing polymers and other used in cosmetic care and conditioning agents and Count mixtures.

In a preferred embodiment, the agent can be sprayed onto the surface to be cleaned or applied in the form of a foam. Particularly suitable for this purpose is a manually activated spray dispenser, in particular selected from the group comprising aerosol spray dispensers, pressure-building spray dispensers, pump spray dispensers and trigger spray dispensers, in particular pump spray dispensers and trigger spray dispensers with a container made of polyethylene, polypropylene or polyethylene terephthalate. Such trigger bottles are offered for example by the company Afa-Polytec. The spray head is preferably equipped with a foam nozzle. In addition to trigger bottles, pump foam dispensers, such as those offered by the company Airspray or the Daiwa Can Company, are also suitable. In addition, the agent can also be added with the addition of a suitable propellant (eg n-butane, a propane / butane mixture, carbon dioxide, nitrogen, or a CO ₂ / N ₂ mixture) are charged into a corresponding Aerosolsprühflasche. However, such a spray dispenser is less preferred.

A further subject of the invention is accordingly a product comprising a cleaning agent according to the invention and a spray dispenser, in particular a cleaning agent according to the invention and a trigger bottle with a foam nozzle.

The agents according to the invention are preferably used for cleaning hard surfaces. Another subject of the invention is therefore the use of a cleaning agent according to the invention for cleaning hard surfaces. Hard surfaces in the context of this application are windows, mirrors and other glass surfaces, surfaces made of ceramic, plastic, metal or wood and lacquered wood, which are found in household and commercial, such as bathroom ceramics, kitchen surfaces or floors. The detergent is diluted before use with water or, in particular by means of a spray dispenser, applied undiluted. In a method for cleaning hard surfaces, therefore, the cleaning agent according to the invention is applied in one process step to the surface to be cleaned.

In a further preferred embodiment, the agents according to the invention are used for stain removal and / or for spot pretreatment on textiles. Here they are particularly suitable for the treatment of fatty stains. A further subject of the invention is accordingly the use of a cleaning agent according to the invention for stain removal and / or for spot pretreatment on textiles, in particular for greasy stains.
