Definitions
- the present invention relates to detergents and cleaners, in particular to automatic dishwashing compositions containing glycerol esters for preventing the discoloration of plastic dishes, to dishwashing methods using these dishwashing detergents, and to the use of dishwashing agents for preventing the discoloration of plastic dishes.
- WO 2010/078979 discloses the use of porous polyamide particles and of synthetic phyllosilicates for reducing the discoloration of plastic dishes.
- the object of the present invention was therefore to provide alternative compounds which at least reduce the occurrence of discoloration on plastics in the course of automatic dishwashing as a result of colored food residues.
- the mono- and diesters of glycerol are, for example, as degradation products of dietary fats in fat digestion (lipolysis).
- Glycerol esters are used primarily as emulsifiers in the production of pastry and confectionery, chocolate products, margarine, baby food, cocoa powder, milk powder, mashed potatoes, rice and pasta. Surprisingly, it has been found that these compounds are effective inhibitors of plastic discoloration.
- a first subject of the present invention therefore detergents and cleaners containing glycerol esters, wherein the glycerol in the glycerol ester with one or two branched or unbranched, saturated or unsaturated C 5 . 2 i-fatty acids, preferably C 2-20 fatty acids, particularly preferred is esterified Ci -2O 6 fatty acids. If the ester bond is formed only with a C5.21 fatty acid, the ester bond is preferably formed here with a terminal hydroxyl group of the glycerol.
- the remaining hydroxy groups of the glycerol ester which are not C 5 . 2 i fatty acid are esterified, free.
- At least one further hydroxy group of the glycerol ester preferably exactly one hydroxyl group of the glycerol ester, with a C 2 . 6 - carboxylic acid esterified.
- 6- carboxylic acid preferably comprises further hydrophilic groups, in particular carboxy groups and / or hydroxyl groups, preferably up to two further carboxy groups - in addition to the carboxy group which forms the ester bond with the glycerol - and / or up to 5 hydroxy groups.
- 6- carboxylic acid is particularly preferably selected from acetic acid, propionic acid, lactic acid, oxalic acid, citric acid, isocitric acid, tartaric acid, tartronic acid, glycolic acid, malic acid and gluconic acid.
- the glycerol ester is a compound in which the glycerol is firstly branched or unbranched, saturated or unsaturated C 5 . 2 i-fatty acid, preferably Ci 2 - 20 fatty acid, more preferably Ci 6 - 2 o fatty acid, especially cis-fatty acid, and on the other hand with a hydrophilic modified C 2 described above. 6 carboxylic acid is esterified. Preferably, in this preferred embodiment, both ester bonds are terminal.
- Esters of glycerol which can be used according to the invention are commercially available, for example, under the trade name Grindsted (Danisco), in particular under the trade names Grindsted® Acetic, Grindsted® Citrem, Grindsted® Mono-Di and Grindsted® Lactem.
- the glycerol ester is preferably present in detergents and cleaners according to the invention in an amount of from 0.05 to 30% by weight, in particular from 0.1 to 10% by weight, particularly preferably from 0.5 to 5% by weight.
- the washing or cleaning agent according to the invention in a preferred embodiment is a machine dishwashing detergent.
- the washing and cleaning agent according to the invention in particular the machine dishwashing detergent according to the invention, preferably contains at least one further constituent, preferably at least two further constituents selected from the group consisting of builders, surfactants, polymers, bleaches, bleach activators, enzymes, glass corrosion inhibitors, corrosion inhibitors, disintegration auxiliaries, Perfumes and perfume carriers.

- Desintegration aids may preferably be used in amounts of from 0.5 to 10% by weight, preferably from 3 to 7% by weight and in particular from 4 to 6% by weight, based in each case on the total weight of the disintegration assistant-containing agent.
- perfume oils or perfumes within the scope of the present invention, individual fragrance compounds, e.g. the synthetic products of the ester, ether, aldehyde, ketone, alcohol and hydrocarbon type are used. Preferably, however, mixtures of different fragrances are used, which together produce an attractive fragrance.
- perfume oils may also contain natural fragrance mixtures such as are available from vegetable sources, e.g. Pine, Citrus, Jasmine, Patchouly, Rose or Ylang-Ylang oil.
- the preparation of automatic dishwashing agents according to the invention can take place in different ways.
- the agents may be in solid or liquid form as well as in a combination of solid and liquid forms. Powder, granules, extrudates, compacts, in particular tablets, are particularly suitable as firm supply forms.
- the liquid supply forms based on water and / or organic solvents may be thickened, in the form of gels.
- Inventive agents can be formulated in the form of single-phase or multi-phase products.
- automatic dishwashing detergents with one, two, three or four phases are preferred.
- Machine dishwashing detergent characterized in that it is in the form of a prefabricated dosing unit with two or more phases, are particularly preferred.
- the individual phases of multiphase agents may have the same or different states of aggregation.
- Machine dishwashing detergents which have at least two different solid phases and / or at least two liquid phases and / or at least one solid and at least one solid phase are preferred.
- Automatic dishwasher detergents according to the invention are preferably prefabricated to form metering units. These metering units preferably comprise the necessary for a cleaning cycle amount of washing or cleaning-active substances. Preferred metering units have a weight between 12 and 30 g, preferably between 14 and 26 g and in particular between 16 and 22 g.
- the automatic dishwasher detergents according to the invention in particular the prefabricated metering units, have a water-soluble coating, with particular preference.
- the subject matter of the present application is furthermore a method for cleaning dishes in a dishwashing machine, in which the agent according to the invention is metered into the interior of a dishwasher during the passage of a dishwashing program before the main wash cycle or during the main wash cycle.
- the metering or the entry of the agent according to the invention into the interior of the dishwasher can be done manually, but preferably the agent is metered into the interior of the dishwasher by means of the metering chamber.
- a typical frame formulation for a preferably usable automatic dishwashing detergent includes the following substances:
- Polycarboxylate 0, 1-10% by weight
- Nonionic surfactant 0.5-10% by weight Phosphonates 0.5-5% by weight
- Example 1 Inhibition of staining of plastic in automatic dishwashing using dishwasher tablets
- ballast dirt 15 g olive oil, 5 g vinegar essence, 80 g tomato ketchup, 3.7 g paprika spice, 3.7 g curry spice, 10 g salt.
- a commercial dishwashing tablet was used on the one hand, and the same commercial dishwashing tablet in combination with 2 grams of Grindsted Lactem P22 or in combination with 2 grams of Grindsted Acetem 70 on the other hand.
- the values L, a and b were measured before and after each cleaning with the aid of a colorimeter (Datacolor DC 600-3). The ⁇ value was subsequently determined from these values. The lower the determined ⁇ value, the lower the soiling of the boards. The results are shown in the following table.
- Example 2 Inhibition of staining of plastic in automatic dishwashing using dishwashing powder
- Polypropylene breakfast slices were subjected to automatic dishwashing (dishwasher Bosch SGS 57M22, program 70 ° C (time-reduced), water hardness 21 ° dH). fen.
- the following ballast dirt was used: 15 g olive oil, 5 g vinegar essence, 80 g tomato ketchup, 3.7 g paprika spice, 3.7 g curry spice, 10 g salt.
- a commercial dishwashing detergent powder was used as well as the same commercial dishwasher detergent powder in combination with 2 grams of Grindsted Lactem P22 or in combination with 2 grams of Grindsted Acetem 70.
- the values L, a and b were measured before and after each cleaning with the aid of a colorimeter (Datacolor DC 600-3). The ⁇ value was subsequently determined from these values. The lower the determined ⁇ value, the lower the soiling of the boards. The results are shown in the following table.
