Definitions
- the present invention belongs to the area of detergents and refers to a new blend of surfactants, rinse aid compositions comprising them and their use as rinse aid surfactants.
- Standard commercial rinse aids are mixtures of non-ionic surfactants, solubility promoters, organic acids solvents, polymers and dyes, water and optionally preservatives and fragrances.
- the aim of the surfactants in these compositions consists in influencing the interfacial tension of the water in such a way that it can run off from the ware in the thinnest possible, coherent film so that no water drops, streaks or films are left behind during the subsequent drying process (so-called wetting effect).
- wetting effect A distinction is generally made here between two types of deposits: firstly, the so-called “spotting” is investigated, which arises as a result of drying water drops, and secondly "filming" is evaluated, i.e.
- combination products have increasingly been used; these combine the different functions, such as cleaning, clear rinsing, water softening and optionally metal protection, in particular silver protection, or a glass protection function in one, preferably solid, supply form.
- Such compositions are referred to as multifunctional compositions.
- so-called three-in-one products which combine cleaner, rinse aid and water softener in the form of a solid compact ("tab") are found on the market.
- tab solid compact
- Drying performance is to be understood here as meaning to what extent the cleaned ware still has water, preferably water drops, on the surface after passing through the dishwashing process.
- dishwashing detergents or additives in such compositions, which shorten the high energy-expenditure drying step, or make it possible to dry at a lower temperature, while providing the same or even better results in shorter times.
- Ways are therefore sought to improve the drying performance of cleaners for hard surfaces, particular with regard to plastic and metal ware, and more particular of dishwashing detergents for automatic dishwashing, where, here, in particular those solutions are sought in which the performance in the clear-rinse cycle is increased in order to shorten time and to save energy.
- Object of the present invention is a liquid rinse aid composition, comprising a surfactant blend comprising or consisting of

Description
- The present invention belongs to the area of detergents and refers to a new blend of surfactants, rinse aid compositions comprising them and their use as rinse aid surfactants.
- Nowadays, higher demands are placed on machine-washed dishes than on manually washed dishes. For example, even dishes completely cleaned of food residues are not assessed as perfect if, after machine dishwashing, they still have whitish spots based on water hardness or other mineral salts which, due to a lack of wetting agent, originate from dried water drops. In order to obtain brilliantly clear and spot-free dishes, rinse aids are therefore used. The addition of liquid or solid rinse aid ensures that the water runs off from the ware as completely as possible, meaning that the wide variety of surfaces are residue-free and shiny at the end of the wash programme. Standard commercial rinse aids are mixtures of non-ionic surfactants, solubility promoters, organic acids solvents, polymers and dyes, water and optionally preservatives and fragrances. The aim of the surfactants in these compositions consists in influencing the interfacial tension of the water in such a way that it can run off from the ware in the thinnest possible, coherent film so that no water drops, streaks or films are left behind during the subsequent drying process (so-called wetting effect). A distinction is generally made here between two types of deposits: firstly, the so-called "spotting" is investigated, which arises as a result of drying water drops, and secondly "filming" is evaluated, i.e. layers which are formed by the drying of thin water films containing food rests or increased salt concentration in rest water. For the evaluation, test persons are currently used who visually evaluate the parameters of "spotting" and "filming" on cleaned objects, e.g. plates, glasses, knives etc. Modern dishwashing detergents therefore comprise rinse aids in order to improve the run-off of water from the surfaces of the ware. However, there are rinse aids which do not dry equally as well on all substrates, such as e.g. plastic and metal. In order to get round this effect, complex rinse aids are formulated which have e.g. silicone compounds and/or fluorinated compounds, as are described in
US 5,880,089 orUS 2005/0143280 A1 . However, these compounds are biodegradable with difficulty, if at all, and some are even hazardous to the environment. - More recently, moreover, combination products have increasingly been used; these combine the different functions, such as cleaning, clear rinsing, water softening and optionally metal protection, in particular silver protection, or a glass protection function in one, preferably solid, supply form. Such compositions are referred to as multifunctional compositions. Thus, for example so-called three-in-one products which combine cleaner, rinse aid and water softener in the form of a solid compact ("tab") are found on the market. As a result of the increased use of such multifunctional compositions, however, the drying performance has become worse compared to using a classic rinse aid. Drying performance is to be understood here as meaning to what extent the cleaned ware still has water, preferably water drops, on the surface after passing through the dishwashing process. The water remaining on the surface then has to either be removed mechanically (e.g. by wiping dry) or the ware has to be left to dry in the air. The user thus has to wait until the water has evaporated. In this connection, however, residues (e.g. lime and/or surfactant residues or other residues which were dissolved or dispersed in the water) remain on the surface and lead to unaesthetic spots or streaks. This is true to a particular extent on shiny or transparent surface, such as e.g. glass or metal. For improved drying in a dishwasher, an extension or intensification of the drying phase would also in principle be conceivable, e.g. as a result of increasing the temperature in the drying step. However, not all ware withstands higher temperatures, and plastic articles in particular may be sensitive. An extension of the drying phase is in most cases perceived as a disadvantage by users.
- The state of the art proposes quite a number of non-ionic surfactants as suitable additives for rinse aids in order to improve performance and reduce cycle time. For example:
- Fatty acid alkanol amide polyglycol ethers (
EP 2204439 A1 , COGNIS); - Polyol akyl ethers (
EP 1607468 B1 , HENKEL); - Fatty alcohol polyglycol ethers with defined chain length and degree of alkoxylation (
EP 1727884 B1 , HENKEL); (US 5,273,677 ); or - Acrylic acid polyglycol ethers (
WO 2004 013269 A1 , HENKEL). - However, none of these examples fulfil the needs as explained above.
- As a matter of fact, the measures as described above lead to an increased energy consumption of the machine. However, it is desired to avoid the latter since energy consumption is becoming an ever more important selling criterion for dishwashing detergents. For some time, consumers have already been paying more and more attention to the energy consumption of domestic appliances. There are even already standards, inter alia for energy consumption and drying performance, thus e.g. the standard OEVN/OENORM EN 50242 edition 2003-11-01, valid for Austria, or the contextually similar standard for Germany, DIN EN 50242. Here in particular the edition 2005-06 "Electric dishwashers for household use-measurement methods for use properties" (IEC 60436:2004, modified); German version EN 50242:2004).
- There is therefore an increased need for technical solutions for making dishwashing processes more effective and in particular more energy-saving. Such solutions may also be the use of dishwashing detergents, or additives in such compositions, which shorten the high energy-expenditure drying step, or make it possible to dry at a lower temperature, while providing the same or even better results in shorter times.
- Ways are therefore sought to improve the drying performance of cleaners for hard surfaces, particular with regard to plastic and metal ware, and more particular of dishwashing detergents for automatic dishwashing, where, here, in particular those solutions are sought in which the performance in the clear-rinse cycle is increased in order to shorten time and to save energy.

The fatty acid amide derivative known under the CTFA name of Cocamidopropyl Betaine is particularly preferred. Ampholytic surfactants are also suitable emulsifiers. Ampholytic surfactants are surface-active compounds which, in addition to a C8/18 alkyl or acyl group, contain at least one free amino group and at least one -COOH- or -SO3H- group in the molecule and which are capable of forming inner salts. Examples of suitable ampholytic surfactants are N-alkyl glycines, N-alkyl propionic acids, N-alkylaminobutyric acids, N-alkyliminodipropionic acids, N-hydroxyethyl-N-alkylamidopropyl glycines, N-alkyl taurines, N-alkyl sarcosines, 2-alkylaminopropionic acids and alkylaminoacetic acids containing around 8 to 18 carbon atoms in the alkyl group. Particularly preferred ampholytic surfactants are N-cocoalkylaminopropionate, cocoacylaminoethyl aminopropionate and C12/18 acyl sarcosine.
- As a further component, the rinse-aid compositions comprise a hydrotrope (component d). Hydrotropes are agents which act as solubility promoter for a second, more sparingly soluble substance.
- The preferred hydrotropes are selected from the group of cumene sulfonates, xylene sulfonates, propylene glycols and their mixtures, and here preferably 1,2-monopropylene glycol, preference being given to cumene- and xylene sulfonates.
- Cumene- and xylene sulfonates are to be regarded as particularly preferred component (d), here in particular the sodium salts of cumene- or xylene sulfonate. Particular preference is given to cumene sulfonate, sodium salt.
- As another optional component (e), the rinse aids according to the invention may comprise an organic acid and here usually organic hydroxycarboxylic acids which are preferably selected from the group mandelic acid, lactic acid, hydroxysuccinic acid, citric acid, tartaric acid and their mixtures, with particular preference being given to citric acid.
- The rinse aid compositions of the present invention may further comprise non-ionic surfactants different from components (a) and (b), cumene sulfonate and/or citric acid.
- In particular such composition may encompass
- (a) 5 to 15 % b.w. surfactant of formula (I);
- (b) 1 to 5 % b.w. surfactant of formula (II);
- (c) 0 or 1 to 5 % b.w. co-surfactants;
- (d) 0 or 1 to 15 % b.w. hydrotropes;
- (e) 0 or 1 to 5 % b.w. organic acids,
- The compositions of the present invention can also comprise polymers, although it may be preferred for the compositions to be free from polymers, in particular free from polymers which comprise poly(meth)acrylic acid monomers.
- The compositions are prepared by mixing the different components, optionally with the input of energy by stirring and/or heating of the mixtures. Preferably, after introducing the water as initial charge, the remaining components are added in any order with stirring and then the mixture is further stirred until clear.
- Besides the essential components a) to c) and water, further ingredients that are customary per se may also be present in the rinse aids according to the invention. These are preferably selected from the group of alcohols and here preferably the short-chain alcohols ethanol, propanol, isopropanol, butanol, isobutanol. Moreover, the compositions can also comprise further additives, such as e.g. alkylpyrrolidones, polymers, e.g. polycarboxylates or preservatives, e.g. isothiazolinones.
- The compositions can, however, also comprise perfumes, dyes, UV protection, e.g. benzophenones, pH regulators and further customary additives, e.g. those for preventing glass or metal corrosion and for protecting metals against tarnishing. The pH of the compositions can be in the range from pH 3 to 10, preferably from pH 3.5 to 8 and particularly preferably from 4 to 7 or 4 to 6. It is generally the case that acidic compositions (pH<7) may be preferred.
- However, preference is given to those aqueous compositions which comprise only the components (a) to (e). Furthermore, it may be advantageous to dispense with the presence of hydrocarbons and in particular terpenes. In one preferred embodiment of the invention, the compositions are therefore free from terpenes and/or hydrocarbons.
- The present application further provides the use of compounds of the general formula (I) according to claim for producing aqueous rinse aids, or for producing dishwashing detergents. Particular preference is moreover given to the use of compounds of the general formula (I) according to the above description for improving the drying performance of rinse aids for dishwashing, or of dishwashing detergents.
- Another object of the present invention relates to a surfactant blend consisting of
- (a) a first non-ionic surfactant of formula (I)
R1O(EO)n1(PO)p(EO)n2 (I)
in which- R1 stands for a linear alkyl radical having 9 or 11 carbon atoms;
- n1 stands for 0 or an integer of from 6 to 10;
- n2 stands for 0 or an integer of from 6 to 10;
- p stands for 0 or an integer of from 4 to 6;
- (b) a second non-ionic surfactant of formula (II)
R2O(EO)m1(PO)q(EO)m2 (II)
in which- R2 stands for a linear alkyl radical having 10 carbon atoms;
- m1 stands for 0 or an integer of from 6 to 10;
- m2 stands for 0 or an integer of from 6 to 10;
- q stands for 0 or an integer of from 4 to 6;
- Preferably the components (a) and (b) are present in said blend in a ratio by weight of from 1:5 to 5:1, and preferably 2:1 to 3:1.
- The surfactant blends according to formulae (I) and (II) can be incorporated into customary rinse aids and in particular dishwashing detergents on their own or in combination with the components (c) to (e). The dishwashing detergents may be solid, or in pressed form, e.g. as a tablet, or be liquid or gel-like. The compounds of the formula (I) are present in ready-formulated dishwashing detergents preferably in amounts of from 1 to 45 percent by weight, in particular in amounts of from 4 to 30 percent by weight and particularly preferably in amounts of from 15 to 30 percent by weight.
- Such ready-formulated, thus standard commercial dishwashing detergents comprise e.g. builder materials, surfactants, bleaches, bleach activators, enzymes, enzyme stabilizers, corrosion inhibitors, film inhibitors, complexing agents, inorganic salts, graying inhibitors, foam inhibitors, silicone oils, soil release compounds, colour transfer inhibitors, salts of polyphosphonic acids, optical brighteners, fluorescent agents, disinfectants, fragrances, dyes, antistatics, ironing auxiliaries, phobicization and impregnation agents, swelling and nonslip agents, UV absorbers, pH regulators, or a mixture thereof.
- Typical formulations of such compositions for machine dishwashing comprise pentasodium triphosphate (s. sodium phosphates) in amounts of 0, or 1 to 50 percent by weight. Sodium citrate in amounts of from 30 to 45 percent by weight, sodium polycarboxylate in amounts of from 5 to 8 percent by weight, sodium metasilicate in amounts of from 10 to 60 percent by weight, 0 sodium hydrogen carbonate in amounts of from 10 to 25 percent by weight, sodium disilicate in amounts of from 10 to 30 percent by weight, sodium perborate in amounts of from 5 to 10 percent by weight, bleach activators in amounts of from 2 to 4 percent by weight, enzymes, preferably protease and amylase, in amounts of from 1 to 6 percent by weight, low-foam non-ionic surfactants in amounts of from 1 to 20 percent by weight, silver/glass protection and fragrances in amounts up to 5 percent by weight. Suitable surfactants are anionic, non-ionic, cationic and/or amphoteric surfactants, where non-ionic surfactants and here low-foam non-ionic surfactants may be particularly preferred. The latter are preferably selected from the class of fatty alcohol alkoxylate, preferably the fatty alcohol ethoxylates, where end-group-capped derivatives may also be suitable.
- The surfactant blends of formulae (I) and (II) show, alone or preferably in combination with hydrotropes (d) in rinse aids or in dishwashing detergents during automatic dishwashing, an improved drying behaviour on porcelain, glass, metal and plastic (e.g. in the case of Tupperware, SAN (=styreneacrylonitrile), melamine, polypropylene, polyethylene). The improved drying performance on plastic and metal substrates is particularly well pronounced. The improved drying behaviour is moreover more pronounced when using low-temperature programmes or saving or eco programmes with a reduced maximum temperature in the clear-rinse cycle and/or in the drying step. In one preferred embodiment, the compounds of the formula (I) are used rinse aids or dishwashing detergents as additives which serve to improve the drying performance and/or the cleaning performance. The surfactant blends can be used here either in aqueous compositions, preferably in aqueous rinse aids, or else in solid compositions. In general, the surfactant blends are suitable for producing rinse aids or dishwashing detergents.
- The present application therefore further provides a method for rinsing a hard surface in an automatic dishwashing machine, wherein said surfaces are brought into contact with the rinse aid composition or the surfactant blend of the invention. More particularly, the present invention encompasses a method for automatic dishwashing, where the ware passes through at least one cleaning cycle using a detergent and water, at least one clear-rinse cycle using a rinse aid and water, and a final drying cycle, where the temperature in the drying cycle does not exceed 50 °C, where a surfactant blend as per the above description is used. By using surfactant blend in a rinse aid composition as defined above, cleaning performance is improved and the drying temperatures can be reduced from the 70 to 60 °C otherwise customary in such processes to 55 °C or even lower, e.g. down to 45 or 50 °C.
- Another object of the present invention is related to use of the surfactant blend as defined above for making liquid rinsing aids. As explained above, the use of the surfactant blends of the present invention in dishwashing detergents and/or in rinse aids thus permits both a notable improve in performance and a saving of energy compared with current dishwashing processes and compositions since, on account of the improved drying behaviour, a shorter drying time or preferably a lower drying temperature, preferably less than 60 degrees centigrade and in particular from 40 to 59 °C, very particularly preferably from 45 to 55 °C, can be used. The washing process according to the above description is suitable for meeting the requirements placed on drying performance and energy consumption according to the German standard DIN EN 50242.
- Finally, another object of the present invention is related to the use of the liquid rinse aids for making solid dishwashing agents, such as for example powders, tablets, granules and extrudates.
- The following Table 1 shows the exceptional performance of the compositions comprising the surfactant mixture according to the invention on plastic and metal wares. All the formulations have exactly the same frame formulation with the non-ionic surfactant active amount (w/w) being 14%. They differ only in non-ionic surfactant types.
- The test method is defined by wfk institute. Rinse aid performance is tested with an automatic dish washing machine of Miele G 1222 SC type over 3 rinse cycles, using Universal 55 °C programme with prewash. Water hardness is 8-10 °d. The test compositions were placed in the dish washer with 50 g soil. 20 g automatic dishwasher cleaner was dosed at the beginning of washing process and 5 mL of rinse aid is dosed at the beginning of the rinse cycle.
- Substrates tested:
- Porcelain plate
- 3 different types of glass: potassic crystal glass, crystalline glass, soda lime glass
- Stainless steel knives
- Plastic bowls made of polypropylene
- A visual assessment described in Tenside Surf. Det. 28 (1991) 5 is used to determine the performance of all the dishware. The results are shown in Table 1 and represent median values over 3 trials for plastic and steel respectively.
