Definitions
- the invention relates to new aqueous bleaching and disinfecting agents containing alkali metal hypochlorites, surfactants, electrolyte salts and tetrahydromyrcenol in defined proportions.
- EP-A 0274885 recommends the use of mixtures of linear and branched amine oxides.
- EP-A 0145084 Unilever
- mixtures of amine oxides with soaps, sarcosinates, taurides or sugar esters can also be used for this purpose.
- EP-A 0079102, EP-A 0137551 and EP-A 0447261 disclose the use of amine oxides with soap or sarcosinate and other anionic surfactants, for example alkyl sulfates, alkyl ether sulfates, secondary alkane sulfonates or alkylbenzenesulfonates as a thickening component.
- EP-A 0156438 reports on the use of alkylarylsulfonates as thickeners in aqueous bleaching agents which contain certain stilbene dyes as optical brighteners.
- ES-A 8801389 (Henkel Iberica) relates to bleaching agents based on aqueous hypochlorite solutions which contain, as the surfactant component, predominantly alkyl ether sulfates and also small amounts of amine oxides. From EP-A1 0447261 aqueous bleaching agent compositions are also tongues containing sodium hypochlorite and anionic surfactants known. However, the hypochlorite concentration of these agents is 0.1 to 8 and preferably 0.5 to 5% by weight of active chlorine.
- German Patent DE-C1 4333100 the applicant has already proposed stable and sufficiently viscous aqueous bleaching and cleaning agents based on hypochlorites, fatty alcohol ether sulfates and amine oxides, which contain amine oxide phosphonic acids as a mandatory component. Although these contribute significantly to the thickening of the agents, they cannot stabilize the active chlorine content.
- US Pat. No. 4,588,514 discloses alkaline hypochlorite bleaches which contain amine oxides and small amounts of alkyl ether sulfates and soaps to adjust the viscosity.
- the preparations have a high hypochlorite content of 7% by weight.
- the object of the invention was therefore to provide new aqueous bleaching agents and disinfectants which are characterized by a sufficiently high and stable viscosity at a low active chlorine content.
- an additional task was to develop thickeners for hypochlorite bleaches, which can take on further tasks in the formulations.
- the invention relates to bleaching and disinfecting agents containing - based on the agents -
- bleaching agents and disinfectants of the specified additives composition are not only stable to chlorine, but also have a sufficiently high and constant viscosity due to the addition of tetrahydromyrcenol.
- the invention includes the knowledge that the tetrahydromyrcenol not only has a thickening effect, but also acts as an active chlorine-stable fragrance, which can lead to a simplification of the formulation and thus to an economic advantage, since other, usually significantly more expensive perfumes do not have to be worked in additionally.
- Alkali metal hypochlorites are to be understood as meaning lithium, potassium and in particular sodium hypochlorite.
- the hypochlorites can preferably be used in amounts of 2 to 4% by weight, based on the.
- Alkyl ether sulfates are known anionic surfactants which are obtained by sulfation of nonionic surfactants of the alkylpolyglycol ether type and subsequent neutralization.
- the alkyl ether sulfates which are suitable for the purposes of the agents according to the invention follow the formula (I)
- R 1 represents an alkyl radical having 12 to 18 carbon atoms
- n represents numbers 2 to 5
- X represents sodium or potassium.
- Typical examples are the sodium salts of sulfates of the Ci2 / i4-coconut alcohol-2, - 2,3- and -3-EO adduct.
- the alkyl ether sulfates can have a conventional or narrow homolog distribution.
- the alkyl ether sulfates are preferably used in amounts of 2 to 4% by weight, based on the composition.
- Amine oxides are also known substances, which are occasionally attributed to the cationic, but usually the nonionic surfactants. They are prepared from tertiary fatty amines, which usually have either one long and two short or two long and one short alkyl radical, and are oxidized in the presence of hydrogen peroxide.
- the amine oxides which are suitable for the purposes of the invention follow the formula (II) R3
- R 2 represents a linear or branched alkyl radical having 12 to 18 carbon atoms and R 3 and R 4 independently of one another R 2 or an optionally hydroxyl-substituted alkyl radical having 1 to 4 carbon atoms.
- Amine oxides of the formula (II) are preferably used, in which R 2 and R 3 are C12 / 14 or C 2 / i8 cocoalkyl radicals and R 4 is a methyl or a hydroxyethyl radical.
- amine oxides of the formula (II) in which R 2 is a C12 / 14 or C12 / 18 cocoalkyl radical and R 3 and R 4 have the meaning of a methyl or hydroxyethyl radical.
- the amine oxides are preferably used in amounts of 1.5 to 3% by weight, based on the composition.
- Suitable alkali metal hydroxides are potassium hydroxide and in particular sodium hydroxide, which are preferably used in amounts of 1.5 to 2% by weight, based on the composition, and serve to bring the pH of the composition to an optimal value of 12.5 to set 14.
- Suitable electrolyte salts are the alkali and alkaline earth metal carbonates, chlorides, silicates, phosphates and phosphonates and mixtures thereof.
- Sodium or potassium carbonate or chloride are preferably used, which not only bring about the desired buffering of the preparation, but also additionally perform a sequestration of metal, in particular heavy metal, ions.
- An additional advantage is their low price and ease of incorporation.
- the electrolyte salts are preferably used in amounts of 1 to 2% by weight, based on the composition.
- Tetrahydromyrcenol follows the formula (IV).
- the terpene is obtained by hydrogenating myrcenol, which is a precursor to the production of geraniol and citronellol. (IV)
- the preferred amounts are 0.1 to 0.5% by weight, based on the
- the agents according to the invention may contain fatty acid salts of the formula (III) as further constituents,
- R 5 CO is an acyl radical having 12 to 22 carbon atoms and X is an alkali metal.
- Typical examples are the sodium and / or potassium salts of lauric acid, myristic acid, palmitic acid, palmoleic acid, stearic acid, isostearic acid, oleic acid, elaidic acid, petroselinic acid, linoleic acid, linolenic acid, elaeostearic acid, arachic acid, gadoleic acid, behenic acid and technical mixtures as they occur in the pressure splitting of technical fats and oils. Salts of technical coconut or tallow fatty acids are preferably used.
- the fatty acids which are neutralized in situ when they are introduced into the mixture can also be used instead of the salts.
- the fatty acid salts are preferably used in amounts of 0.5 to 2% by weight, based on the composition.
- the agents according to the invention have a viscosity above 500 mPas - measured at 20 ° C. in a Brookfield viscometer -, are stable in storage, resistant to chlorine consumption and are distinguished by excellent dispersibility for dye pigments.
- Another object of the invention relates to the use of tetrahydromyrcenol as a chlorine-stable fragrance and thickener in hypochlorite-containing bleaching and disinfecting agents.
- auxiliaries and additives which the preparations may further contain are further chlorine-stable surfactants or hydrotropes, such as alkyl sulfates, alkyl sulfonates, alkyl benzenesulfonates, xylene sulfonates, sarcosinates, taurides, isethionates, sulfosuccinates, betaines, sugar esters, fatty alcohol polyglycol ethers and alkyl oligoglycosides.
- the sum of these additional surfactants preferably makes up at most 10% by weight of the total amount of surfactants in the formulation.
- alkyl sulfates in amounts of 0.5 to 3% by weight is particularly preferred.
- the agents can contain further active chlorine-stable fragrances, optical brighteners, dyes and pigments in a total amount of 0.01 to 0.5% by weight, based on the agents.
- the fragrances known to be active chlorine-resistant include, for example, monocyclic and bicyclic monoterpene alcohols and their esters with acetic or propionic acid (for example isoborneal, dihydroterpene oil, isobornyl acetate, dihydroterpenyl acetate).
- the optical brighteners can be, for example, the potassium salt of 4,4'-bis (1, 2,3-triazolyl) - (2 -) - stilbin-2,2-sulfonic acid, which is sold under the Phorwite® BHC brand 766 is distributed.
- Possible color pigments include green chlorophthalocyanines (Pigmosol® Green, Hostaphine® Green) or yellow Solar Yellow® BG 300 (Sandoz).
- Polyacrylates, amine oxide phosphonic acids and lignin sulfonates and mixtures thereof can also be present as sequestering agents in amounts of 0.1 to 2 and preferably 0.5 to 1% by weight, based on the agent.
- the agents according to the invention are produced by stirring. If necessary, the product obtained can be decanted or filtered to remove foreign bodies and / or agglomerates.
