Definitions
- the invention relates to bleach-containing, paste-like detergents and cleaning agents and to a process for their production.
- Detergents used in the household are tailored to the needs occurring there; they are usually powdery or sufficiently liquid to be poured out and dosed easily. Since liquid detergents of this type are also said to be stable in storage within relatively wide temperature ranges, additions of organic solvents and / or hydrotropes are frequently added, but these do not themselves contribute to the washing or cleaning result and are therefore undesirable. A possibility for circumventing possible dosing problems with insufficiently liquid agents is proposed in the European patent application EP 253 151 A2.
- liquid, partly highly viscous detergents based on nonionic and anionic surfactants which contain polyethylene glycol as hydrotrope and which do not have to be dosed by the user in liquid form, but rather are packed in portions in bags made of water-soluble material, for example polyvinyl alcohol.
- the paste-like detergent described in European patent EP 295 525 B1 consists of a phase which is liquid in the temperature range below 10 ° C. and which is formed from nonionic surfactant, and a solid phase of a certain particle size dispersed therein, which consists of washing alkalis, sequestering agents and optionally anionic surfactants is formed.
- surfactants or their mixtures are used, the pour point (solidification point) of which must be below 5 ° C. in order to avoid solidification of the paste at low transport and storage temperatures.
- This detergent paste is intended for commercial laundries and is so fluid that it can be conveyed via a suction line using a conventional feed pump. It has been found, however, that such pastes cannot always ensure the homogeneity of their ingredients satisfactorily during their production and often tend to separate even during storage. The segregation affects not only the sepa- - 2 -
- Another paste-like detergent which, as a nonionic surfactant, comprises 40 to 70% by weight of ethoxylated fatty alcohol which is liquid at room temperature and has 10 to 20 carbon atoms and an average degree of ethoxylation of 1 to 8 and 20 to 50% by weight of ethoxylated and propoxylated fatty alcohol with 10 to 20 carbon atoms and an average degree of ethoxylation of 2 to 8 and an average degree of propoxylation of 1 to 6 and 1 to 10 wt .-% soap is described in international patent application WO 95/09229.
- This pasty detergent is so structurally viscous that it is not flowable at room temperature under the influence of gravity, but has a significantly lower viscosity when sheared and is then flowable under the influence of gravity.

- a liquid to pasty, bleach-containing detergent is known, each based on the detergent, (A) 20 to 35% by weight of a surfactant component of the composition (AI) 1 to 4% by weight. % anionic surfactants from the class of the sulfonates and the soaps, which are present as alkali salts, (A2) 16 to 34% by weight of nonionic surfactants with a pour point of at most 10 ° C., the alkoxylated linear alcohols or in 2- Methyl-branched alcohols with 10 to 18 carbon atoms or mixtures thereof, (B) 10 to 35% by weight of complexing or alkaline earth metal ion-binding builder salts, (C) 15 to 40% by weight sodium metasilicate, (D) 8 to 25% by weight of bleaching persalts, (E) up to 15% by weight of other detergent constituents and (F) less than 3% by weight of water, with the proviso that the sum of the components
- washing and cleaning agents described in the aforementioned publication are highly viscous and have thixotropic properties. Even if the status stability of the incorporated oxidizing agents is said to be sufficient, it has been found, however, that their cleaning action is unsatisfactory, particularly with regard to bleachable soiling.

- Enzymes stabilized against oxidative damage are preferably used, for example the proteases or amylases known under the trade names Durazym® or Purafect® OxP or Duramyl® or Purafect® OxAm.
- the usual foam regulators which can be used in the agents according to the invention include, for example, polysiloxane-silica mixtures, the fine-particle silica contained therein preferably being silanated.
- the polysiloxanes can be made from both consist of linear compounds as well as cross-linked polysiloxane resins and their mixtures.
- Further defoamers are paraffin hydrocarbons, in particular micro-paraffins and paraffin waxes, the melting point of which is above 40 ° C, saturated fatty acids or soaps with in particular 20 to 22 C atoms, for example sodium behenate, and alkali salts of phosphoric acid mono- and / or dialkyl esters, in which the alkyl chains each have 12 to 22 carbon atoms.
- Sodium monoalkyl phosphate and / or dialkyl phosphate with C 16 to C 18 alkyl groups is particularly preferably used.
- the proportion of foam regulators can preferably be 0.2% by weight to 2% by weight. In many cases, a suitable selection of the nonionic surfactants can reduce the tendency to foam, so that the use of defoaming active ingredients can be dispensed with entirely.
- the present invention further relates to a process for the preparation of the pasty detergent and cleaning agent according to the invention, in which the components of component (A), ie the nonionic surfactants and, if appropriate, the synthetic anionic surfactants and soap, are mixed to form a homogeneous premix are mixed and the components of components (B), (C) and optionally further components are incorporated into this premix.
- component (A) ie the nonionic surfactants and, if appropriate, the synthetic anionic surfactants and soap
- the washing and cleaning agent of the present invention thus produced is pasty and usually consists of a liquid phase and a finely divided solid phase dispersed therein.
- the liquid phase of such agents is essentially formed from the, in particular nonionic, surfactants contained in the agent according to the invention.
- An agent according to the invention preferably has a viscosity of 70,000 mPas to HO OOO mPas at 20 ° C., measured with a Brookfield rotary viscometer (spindle no. 7) at 5 revolutions per minute. Under otherwise identical conditions, the viscosity at 50 revolutions per minute is preferably 18,000 mPa s to 25,000 mPa s.
- the paste-like detergent and cleaning agent preferably has a viscosity at room temperature such that it is not flowable under the influence of gravity. It is then preferably particularly pseudoplastic that it is said to have a significantly lower viscosity when sheared and is flowable under the influence of gravity, it being particularly preferred to determine a viscosity in the range from 8 OOO mPas to 45 OOO mPas at 25 ° C. and a shear rate of 0.01 s ' 1 with a CS rheometer CVO from Bohlin with plate / plate measuring system, plate spacing 1 to 3 mm.
- an agent according to the invention preferably has a viscosity which is considerably lower, as a rule 100 to 2000 times lower, at a shear rate of 10 s -1 and otherwise identical measuring conditions, in particular in the range from 40 mPas to 60 mPas lies.
- the numerical values for viscosity refer to the reading after a measuring time of 3 minutes, in order to take into account any thixotropy effect of the paste.
- the reduction in viscosity in the case of shear is largely reversible, that is to say after the shear has ended, the agent returns to its original physical state without segregation occurring.
- viscosities mentioned do not relate to measurements directly after the paste has been produced, but rather to pastes which are stored, so to speak, in equilibrium, since the shear forces acting in the course of the production process lead to a lower paste viscosity, which leads to a lower viscosity only increased over time to the definitive final viscosity. Storage times of 1 month are usually completely sufficient for this.
- the agent according to the invention can be metered using conventional devices for metering pastes, such as are described, for example, in international patent application WO 95/29282, German patent application DE 196 05 906, German patent DE 44 30418 or European patent EP 0 295 525 and EP 0 356 707 have been described.
- a device which is particularly well suited for metering structurally viscous pasty detergents is known, for example, from international patent application WO 95/09263 and is preferably used for metering structurally viscous pastes according to the invention.
- the detergents and cleaners according to the invention can optionally also be filled pre-portioned into water-soluble films in particular. Films of this type are described, for example, in European patent application EP 253 151. Examples
- the paste-like detergents showed despite their content of oxidizing agents and Bleach activator has a very good storage stability.
- the active oxygen content after storage at 30 ° C. and 40% relative atmospheric humidity only decreased to 95% of the initial value within 8 weeks.
