- Detergents or cleaning agents preferably dishwashing agents, in particular machine dishwashing agents, are usually in solid form (for example as tablets) or in liquid form (or else as a flowing gel).
- Liquid cleaning agents in particular are enjoying increasing popularity with consumers.
- Pre-portioned forms of presentation are popular with consumers because they are easier to dose.
- pre-portioned flowing gels are often problematic because they tend to leak, for example when packaged in single-chamber or multi-chamber bags. At the same time, it is necessary for such gels to have good cleaning and rinsing performance.
- the object of the present invention is to provide a system that provides particularly suitable gel formulations comprising PVOH and / or its derivatives, as well as the provision of cleaning agents, preferably dishwashing detergents, in particular automatic dishwashing detergents, which can be produced easily and cost-effectively, a good Have storage stability and also have good cleaning and / or rinsing performance.
- cleaning agents preferably dishwashing detergents, in particular automatic dishwashing detergents, which can be produced easily and cost-effectively, a good Have storage stability and also have good cleaning and / or rinsing performance.
- At least one further active ingredient preferably selected from dyes, glass corrosion inhibitors, perfumes, pH adjusters and other processing auxiliaries; where at least one of the components according to a) or b) is liquid at 20° C., and with the proviso that for the mixture of the components (number n) according to a) and b) or a), b) and c) the following is applicable: and
- Polyvinyl alcohol can thicken various solvents, thereby forming gels.
- the PVOH is stabilized by non-covalent intermolecular interactions.
- the Hansen solubility parameters are based on a semi-empirical concept developed by Charles M. Hansen. Each substance can be analyzed using the three Hansen parameters, disperse/van der Waals forces (dD); Dipolar interactions (dP) and the ability to form hydrogen bonds (dH) can be characterized.
- Hansen parameters for specific substances can be determined by testing their solubility in reference solvents with known Hansen parameters. Based on such data it is then possible to determine the location of this substance in the Hansen space (Hansen Parameters Users Handbook, 2nd Edition, June 15, 2007)
- the Hansen parameters for the mixture of different substances result from the linear combination of the Hansen parameters of the components in the mixture according to Equation 1 below. PVOH is not taken into account in this equation. The sum of all substances adds up to 1 (equation 2).
- Equation 3 The appropriate section of the Hansen space (three-dimensional space spanned by dD, dP and dH), in which gelation and solubility are given, is fitted by a spherical function with radius r, for which Equation 3 applies.
- gels comprising PVOH and/or its derivatives in an amount, based in each case on the total weight of the gel, from 3 to 40% by weight, preferably from 4 to 20% by weight, in particular from 5 up to 18% by weight, have particularly advantageous properties if they also meet the following parameters.
- the gel shows unfavorable syneresis, i.e. leakage of solvent, on storage, while at r ⁇ 14.0 the gel becomes too soft and no longer has the desired properties in terms of strength and dimensional stability.
- Hansen parameters (dD, dP, dH) for the individual components can be determined experimentally by testing their solubility in reference solvents with known Hansen parameters.
- At least one of the components according to a) or b) is liquid at 20.degree.
- the mixture preferably has no separation of the mixture of the individual components at 80° C. in a period of 10 minutes, preferably 20 minutes, after the components have been mixed.
- a gel or a gel-like phase means a composition (or phase) which has an internally structuring network.
- This internal structuring (spatial) network is formed by the dispersion of a solid but distributed substance with long or highly branched particles and/or gelling agent, here polyvinyl alcohol and/or its derivatives, in at least one liquid (the at least one liquid is liquid at 20° C) formed.
- the washing or cleaning agent preferably dishwashing detergent, in particular machine dishwashing detergent, can have one, two, three, four or more gels or gel phases.
- the gels/gel phases can be the same or different. In the case of several gels or gel phases, these can preferably be distinguished spatially, optically or on the basis of their ingredients. If the gels/gel phases are different, they can have different dyes and different additions of active ingredients.
- the gel is dimensionally stable.
- the polyvinyl alcohol and/or its derivatives are brought into contact with glycerol. This gives a flowable mixture which can be brought into a desired shape.
- a gel/a gel phase is obtained which remains in the specified form, i.e. is dimensionally stable.
- the setting time is preferably 15 minutes or less, preferably 10 minutes or less, particularly preferably 5 minutes or less.
- the gel gives way under pressure, but does not deform as a result, but returns to its original state after the pressure is removed.
- the gel is preferably elastic, in particular linear-elastic.
- the gel is preferably a shaped body.
- a molded body is a single body that stabilizes itself in its imposed shape.
- This dimensionally stable body is formed from a molding compound (e.g. a composition) by deliberately bringing this molding compound into a predetermined shape, e.g. by pouring a liquid composition into a mold and then curing the liquid composition, e.g. as part of a sol-gel process.
- a molding compound e.g. a composition
- the setting time means the period of time during which the gel changes from a flowable to a non-flowable, dimensionally stable state at room temperature during production.
- Room temperature is understood to mean a temperature of 20°C. Where temperatures are mentioned herein, unless otherwise noted, they are to be understood as measured at a pressure of 1013 mbar.
- the gel is a solid gel phase. It is preferably cut-resistant. It can, for example, be cut with a knife after it has solidified without being destroyed further, except at the point where the cut was made.
- a phase within the meaning of the present invention is a spatial area in which physical parameters and the chemical composition are homogeneous.
- a phase differs from another phase by various characteristics, such as ingredients, physical properties, external appearance, etc. Different phases can preferably be distinguished visually.
- the at least one gel phase can be clearly distinguished from other phases (solid, preferably granular, liquid or gel-like) for the consumer.
- the washing or cleaning agent according to the invention preferably dishwashing detergent, in particular machine dishwashing detergent
- these can also be distinguished from one another with the naked eye because they differ from one another, for example in terms of color.
- an optical differentiation of the phases is possible, for example on the basis of a difference in color or transparency.
- Phases within the meaning of the present invention are therefore self-contained areas which the consumer can visually distinguish from one another with the naked eye.
- the individual phases can have different properties when used, such as the speed with which the phase dissolves in water and thus the speed and sequence of release of the ingredients contained in the respective phase.
- the gel is preferably translucent (translucent) or transparent, which results in a good optical impression.
- the transmittance of the gel phase (without dye) is preferably in a range between 100% and 20%, between 100% and 30%, in particular between 100% and 40%.
- the permeability was determined in % at 600 nm against water as a reference at 20 °C. For this purpose, the mass was poured into the 11 mm round cuvettes provided and, after a storage time of 12 h at room temperature, measured in a LICO 300 color measuring system according to Lange.
- the detergents or cleaning agents according to the invention preferably dishwashing detergents, in particular machine dishwashing detergents, contain polyvinyl alcohol and/or its derivatives in an amount of 3 to 40% by weight, in particular 4 to 30% by weight, particularly preferably in an amount of 5 to 18% by weight %, in each case based on the total weight of the gel.
- Polyvinyl alcohols are thermoplastics that are usually produced as a white to yellowish powder by the hydrolysis of polyvinyl acetate. Partially hydrolyzed polyvinyl alcohol which still has amounts of up to 30 mol % of non-hydrolyzed acetyl groups is to be understood as polyvinyl alcohol in the context of the invention.
- Polyvinyl alcohol (PVOH) is resistant to almost all anhydrous organic solvents. Polyvinyl alcohols with a molar mass of 30,000 to 60,000 g/mol are preferred.
- polyvinyl alcohols which are available as yellowish-white powders or granules with degrees of polymerization in the range from about 100 to 2500 (molecular weights from about 4000 to 100,000 g/mol) and degrees of hydrolysis from 80 to 99 mol%, preferably from 85 to 90 mol%, in particular from 87 to 89 mol%, for example 88 mol%, which accordingly still contain a residual content of acetyl groups.
- the gel comprises PVOH (polyvinyl alcohol).
- the gels or gel phases produced in this way have a particularly high melting point, are dimensionally stable (even at 40° C.) and do not change their shape, if at all, only insignificantly, even during storage. In particular, they are also not very reactive with regard to a direct negative interaction with components of a granular mixture, in particular an additional powder phase.
- PVOH can produce both water-containing and water-poor or water-free gel phases.
- low-viscosity melts result at 80-90 °C or 110-120 °C, which are particularly easy to process.
- the gel phase can be filled into the water-soluble coating quickly and precisely , without sticking or the amount being dosed imprecisely. Furthermore, these gel phases adhere particularly well to the water-soluble coating, in particular if this is also made from PVOH. This is also a visual advantage. Due to the rapid solidification of the at least one gel phase with PVOH, the further processing of the gel phases can take place particularly quickly. Furthermore, the good solubility of the gel phases produced is particularly favorable for the overall solubility of the washing or cleaning agent. In addition, gel phases with such short setting times are advantageous in the event that a solid, preferably granular phase dosed thereon, comprising granular mixtures, in particular powder, does not sink into the gel that is not yet completely solidified or is too soft. This leads to visually unappealing washing or cleaning agent portions.
- polyvinyl alcohols which are available as white-yellowish powders or granules with degrees of polymerization in the range from about 100 to 2500 (molar masses from about 4000 to 100,000 g/mol) and degrees of hydrolysis from 80 to 99 mol%, preferably from 85 to 90 mol %, in particular from 87 to 89 mol%, for example 88 mol%, which accordingly still contain a residual content of acetyl groups.
- PVOH powders with the properties mentioned above, which are suitable for use in the at least one gel phase, are marketed, for example, by Kuraray under the name Mowiol® or Poval®.
- Exceval® AQ4104 from Kuraray, for example, is also suitable.
- Particularly suitable are Mowiol C30, the Poval® qualities, in particular the qualities 3-83, 3-88, 6-88, 4-85, and particularly preferably 4-88, very particularly preferably Poval 4-88 S2 and Mowiol® 4- 88 by Kuraray.
- preferred derivatives of PVOH are copolymers of polyvinyl alcohol with other monomers, in particular copolymers with anionic monomers.
- anionic Monomers are preferably suitable vinylacetic acid, alkyl acrylates, maleic acid and their derivatives, in particular monoalkyl maleates (especially monomethyl maleate), dialkyl maleates (especially dimethyl maleate), maleic anhydride, fumaric acid and their derivatives, especially monoalkyl fumarate (especially monomethyl fumarate), dialkyl fumarate (especially dimethyl fumarate), fumaric anhydride, itaconic acid and derivatives thereof, in particular monomethyl itaconate, dialkyl itaconate, dimethyl itaconate, itaconic anhydride, citraconic acid (methylmaleic acid) and derivatives thereof, monoalkyl citraconic acid (especially methyl citraconic acid), dialkyl citraconic acid (dimethyl citraconic acid), citraconic acid anhydride, mesaconic acid (methyl fuma
- Particularly preferred derivatives of PVOH are those selected from copolymers of polyvinyl alcohol with a monomer selected in particular from the group of monoalkyl maleates (especially monomethyl maleate), dialkyl maleates (especially dimethyl maleate), maleic anhydride, and combinations thereof, and the alkali metal salts or esters of the above mentioned monomers.
- the values given for the polyvinyl alcohols themselves apply to the suitable molar masses.
- the gel comprises a polyvinyl alcohol and/or derivatives thereof, preferably polyvinyl alcohol, the degree of hydrolysis of which is preferably 70 to 100 mol %, in particular 80 to 90 mol %, particularly preferably 81 to 89 mol %. % and especially 82 to 88 mol%.
- the water solubility of polyvinyl alcohol can be changed by post-treatment with aldehydes (acetalization) or ketones (ketalization). These are also to be understood as derivatives of polyvinyl alcohol.
- Polyvinyl alcohols which are acetalized or ketalized with the aldehyde or keto groups of saccharides or polysaccharides or mixtures thereof have proven to be particularly preferred and particularly advantageous due to their extremely good solubility in cold water.
- the reaction products of polyvinyl alcohol and starch can be used extremely advantageously.
- the water solubility can be changed by complexing with Ni or Cu salts or by treatment with dichromates, boric acid, borax and thus adjusted to desired values.
- At least one further active ingredient preferably selected from dyes, perfumes, pH adjusters and other processing auxiliaries, can be used.
