Definitions

  • the invention relates to new aqueous bleaches and disinfectants containing alkali metal hypochlorites, Surfactants, electrolyte salts and tetrahydromyrcenol in defined proportions.
  • 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 thickening components.
  • EP-A 0156438 reports on the use of alkylarylsulfonates as thickeners in aqueous bleaches which contain certain stilbene dyes as optical brighteners.
  • ES-A 8801389 Henkel Ibérica
  • aqueous hypochlorite solutions which, as surfactant components, contain predominantly alkyl ether sulfates and also small amounts of amine oxides.
  • Aqueous bleaching agent compositions containing sodium hypochlorite and anionic surfactants are also known from EP-A1 0447261.
  • the hypochlorite concentration of these agents is 0.1 to 8 and preferably 0.5 to 5% by weight of active chlorine.
  • European patent application EP-A-622451 describes perfumed hypochlorite bleaching agents, tetrahydromyrcenol being mentioned as a bleach-stable perfume. It is not disclosed that this increases the viscosity of agents which contain alkyl ether sulfates or their mixtures with amine oxides.
  • the European patent application EP-A-129980 describes hypochlorite-containing bleaching agents with quaternary alkoxysilanes and amine oxides, the viscosity of which can be increased by adding secondary and tertiary alcohols. This document also contains no indication that tetrahydromyrcenol could increase the viscosity of agents with other surfactant compositions.
  • the object of the invention was thus to provide new aqueous bleaching and disinfecting agents which, with a low active chlorine content, are characterized by a sufficiently high and stable viscosity. Finally, an additional task was to develop thickening agents for hypochlorite bleaching agents, which can take on additional tasks in the formulations.
  • 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 agent - be used.
  • Alkyl ether sulfates are known anionic surfactants which are obtained by sulfating nonionic surfactants of the alkyl polyglycol ether type and subsequent neutralization.
  • the alkyl ether sulfates in the context of the agents according to the invention follow the formula (I), R 1 O- (CH 2 CH 2 O) n SO 3 X in which R 1 is an alkyl radical having 12 to 18 carbon atoms, n is numbers 2 to 5 and X is sodium or potassium.
  • Typical examples are the sodium salts of sulfates of the C 12/14 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 agent.
  • Amine oxides are also known substances that are occasionally classified as cationic, but usually classified as 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 they are oxidized in the presence of hydrogen peroxide.
  • the amine oxides which are suitable for the purposes of the invention follow the formula (II), in which 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 represent R 2 or an optionally hydroxy-substituted alkyl radical having 1 to 4 carbon atoms.
  • amine oxides of the formula (II) in which R 2 and R 3 are C 12/14 or C 12/18 coconut alkyl radicals and R 4 is a methyl or a hydroxyethyl radical.
  • R 2 and R 3 are C 12/14 or C 12/18 coconut alkyl radicals and R 4 is a methyl or a hydroxyethyl radical.
  • amine oxides of the formula (II) in which R 2 represents a C 12/14 or C 12/18 coconut alkyl radical and R 3 and R 4 represent a methyl or hydroxyethyl radical.
  • the amine oxides are preferably used in amounts of 1.5 to 3% by weight, based on the agent.
  • potassium hydroxide and especially sodium hydroxide come into consideration, which are preferably used in amounts of 1.5 to 2% by weight, based on the agent, and serve to adjust the pH of the agents to an optimal value of 12.5 to 14.
  • Suitable electrolyte salts are the alkali and alkaline earth carbonates, chlorides, Silicates, phosphates and phosphonates and their mixtures.
  • An additional advantage is its low price and light weight Incorporability.
  • the electrolyte salts are preferably used in amounts of 1 to 2% by weight on the means - used.
  • Tetrahydromyrcenol follows the formula (IV).
  • the terpene is obtained by hydrogenating myrcenol, which is a precursor to the production of geraniol and citronellol.
  • the preferred amounts used are 0.1 to 0.5% by weight, based on the agent.
  • the agents according to the invention can contain fatty acid salts of the formula (III) as further constituents, R 5 CO-OX in which R 5 CO is an acyl radical having 12 to 22 carbon atoms and X is an alkali metal.
  • 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, petroselic acid, linoleic acid, linolenic acid, eleostearic acid, arachidic acid, gadoleic acid, behenic acid and erucic acid, as well as their technical mixtures the pressure splitting of technical fats and oils arise.
  • Salts of technical coconut or tallow fatty acids are preferably used. Since the formulations according to the invention are made strongly alkaline, the fatty acids which are neutralized in situ when they are added to 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 agent.
  • the agents according to the invention have a viscosity above 500 mPas - measured at 20 ° C in a Brookfield viscometer - are storage-stable, against the consumption of chlorine stable and are characterized by excellent dispersibility for dye pigments the end.
  • the invention also relates to the use of tetrahydromyrcenol As a chlorine-stable fragrance and thickener in hypochlorite-containing bleaches and disinfectants.
  • Auxiliaries and additives that the preparations can also contain include, for example other chlorine-stable surfactants or hydrotropes such as alkyl sulfates, alkyl sulfonates, alkylbenzenesulfonates, Xylene sulfonates, sarcosinates, taurides, isethionates, sulfosuccinates, betaines, sugar esters, Fatty alcohol polyglycol ethers and alkyl oligoglycosides.
  • the sum of these makes up additional surfactants from a maximum of 10 wt .-% 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 other active chlorine-stable fragrances, optical brighteners, dyes and Pigments in total amounts of 0.01 to 0.5 wt .-% - based on the agent - contain.
  • active chlorine include, for example, monocyclic and bicyclic ones Monoterpene alcohols and their esters with acetic or propionic acid (e.g. isoborneal, dihydroterpene oil, Isobornyl acetate, dihydroterpenyl acetate).
  • the optical brighteners can be, for example act the potash salt of 4,4'-bis- (1,2,3-triazolyl) - (2 -) - stilbine-2,2-sulfonic acid, which is sold under the trademark Phorwite® BHC 766 is sold.
  • Color pigments include green chlorophthalocyanines (Pigmosol® Green, Hostaphine® Green) or yellow Solar Yellow® BG 300 (Sandoz) are possible.
  • Sequestering agents can also be polyacrylates, amine oxide phosphonic acids and lignosulfonates and their mixtures in amounts of 0.1 to 2 and preferably 0.5 to 1 wt .-% - based on the Means - be included.
  • the agents according to the invention are produced by stirring. Possibly the product obtained can be used to separate foreign bodies and / or agglomerates decanted or filtered.
  • the viscosity was determined at 20 ° C. using a Brookfield viscometer (model RVT, spindle # 1 or # 2, 200 rpm). To determine the chlorine stability, the test mixtures were stored in a colorless plastic bottle under the influence of daylight and the active chlorine content was determined.
  • the formulations 1 to 7 are according to the invention, the formulations V1 to V3 are used for comparison.
