Definitions
- the present application describes surfactant-containing automatic dishwashing detergents, automatic dishwashing processes using these dishwashing detergents, and the use of these dishwashing detergents in automatic dishwashing processes in which portions of a machine cleaning agent from a storage container located in the interior of the dishwasher pass into the interior of the dishwasher over several successive cleaning cycles be dosed.
- One of the major objectives of the machine cleaners manufacturers is to improve the cleaning and rinse performance of these compositions, with more emphasis being placed recently on the cleaning and rinse performance in low temperature or reduced water consumption cleaning cycles.
- Typical types of dishwashing detergent in addition to the traditional liquid dishwashing detergents, include, in particular, the automatic dishwashing detergents marketed predominantly in solid form, which are obtainable, for example, as powders or as tablets.
- automatic dishwashing detergents marketed predominantly in solid form, which are obtainable, for example, as powders or as tablets.
- these known clothing and supply forms are subject to new changes. For some time now, the main focus has been on the simplified dosing of automatic dishwashing detergents.
- devices for the multiple dosing of detergents and cleaning agents have recently come into the field of vision of product developers.
- these devices it is possible to distinguish between dispensing containers integrated in the dishwasher or textile washing machine on the one hand and independent devices which are independent of the dishwasher or textile washing machine on the other hand.
- these devices which contain the multiple of the amount of detergent necessary for carrying out a cleaning process, portions of washing or cleaning agents are metered into the interior of the cleaning machine in an automatic or semi-automatic manner in the course of several successive cleaning processes. For the consumer eliminates the need for repeated manual dosing of detergents and cleaners.
- a washing or cleaning agent contained in a device provided for multiple dosing is repeatedly heated in the course of several washing or cleaning processes to temperatures well above the temperatures customary for transport and storage, with temperature-sensitive active substances in particular being affected.
- the group of these temperature-sensitive washing and cleaning-active substances primarily include the washing and cleaning-active enzymes.
- German patent application DE 2 038 103 (Henkel) teaches the stabilization of enzyme-containing dishwashing detergents by saccharides, while in European patent EP 646 170 B1 (Procter & Gamble) propylene glycol is disclosed for enzyme stabilization in liquid detergents.
- This application was now based on the object to provide a machine dishwashing detergent, which is stabilized against phase separation / loss of activity with multiple temperature fluctuations (10 to 75 0 C) and stored in a dishwasher located inside a storage device without significant loss of activity, compared to conventional automatic dishwashing however characterized by an improved performance profile.
- a first subject of the present application is therefore a detergent combination for automatic dosing in automatic dishwashing comprising
- a detergent preparation B containing b1) at least one nonionic surfactant and b2) at least one cleaning-active enzyme
- a rinse aid composition C containing d) at least one nonionic surfactant containing d) at least one nonionic surfactant.
- the present application describes and claims a detergent combination for automatic dosing in automatic dishwashing.
- the detergent combinations according to the invention for the automatic dosing and for the storage in a metering device in the interior of the automatic dishwasher are provided and necessarily include more than the amount necessary for performing a cleaning cycle amount of the detergent.
- An object of the claim is therefore in other words one
- Detergent combination for automatic dosing in automatic dishwashing comprising
- a detergent preparation B containing b1) at least one nonionic surfactant and b2) at least one cleaning-active enzyme
- a rinse aid composition C comprising c1) at least one nonionic surfactant, wherein the detergent combination comprises the amounts of the cleaning agents B and C which are sufficient for carrying out a machine dishwashing process at least twice, preferably at least four times and in particular at least eight times.
- At least one of the detergent preparations B and C is liquid.
- suitable solvents for these liquid detergent formulations are the organic solvents known to the person skilled in the art, in particular the monohydric or polyhydric alcohols.
- a preferred object of the invention is a detergent combination for automatic dosing in automated dishwashing
- liquid detergent preparation B containing b1) at least one nonionic surfactant and b2) at least one cleaning-active enzyme
- liquid rinse aid composition C comprising c1) at least one nonionic surfactant, wherein the detergent combination comprises sufficient amounts of the cleansers B and C for carrying out a machine dishwashing process at least twice, preferably at least four times and in particular at least eight times.
- Both detergent formulation B and detergent formulation C contain nonionic surfactant.
- Each of detergent formulations B and C may contain one, two or more nonionic surfactant (s).
- the nonionic surfactants in detergent formulations B and C may be identical or different chemical Have structures.
- the detergent formulations B and C have different compositions from each other, so are not identical.
- the weight fraction of the nonionic surfactant in the total weight of the detergent composition B between 0.1 and 30 wt .-%, preferably between 1, 0 and 25 wt .-%, especially preferably between 2.0 and 20% by weight and in particular between 5.0 and 15% by weight.
- Such detergent combinations according to the invention have particularly advantageous cleaning and rinsing effects, in which at least 20 wt .-%, preferably between 20 and 80 wt .-%, particularly preferably between 30 and 75 wt .-% and in particular between 40 and 70 Wt .-% of the total amount of surfactant of the detergent combination in the detergent composition B is included.
- Detergent combinations in which at least 20 wt .-%, preferably between 20 and 80 wt .-%, more preferably between 30 and 75 wt .-% and in particular between 40 and 70 wt .-% of the total amount of the detergent combination in the detergent composition B included can be found in the following Table 1:
- An essential constituent of the washing or cleaning agent preparations B and C according to the invention are the nonionic surfactants, nonionic surfactants of the general formula R 1 -CH (OH) CH 2 O- (AO) w - (AO) x - (A "O) y - (A "'O) z -R 2 , in the
- R 1 is a linear or branched, saturated or mono- or polyunsaturated C 6 - 24 represents alkyl or alkenyl;

- CH 2 -CH (CH 2 -CH 3 ), w, x, y and z are values between 0.5 and 120, where x, y and / or z can also be 0, are preferred.
- these surfactants have proven to be superior to other known nonionic surfactants of the prior art.
- hydroxy mixed ethers are used both in the detergent formulation B and in the detergent preparation C, in addition to the rinse aid result, it is additionally possible to improve the formation of deposits on surfaces such as glass, plastic or stainless steel. This improvement is detectable over a machine dishwashing detergent containing the same amount of hydroxy mixed ether alone in one of the two detergent formulations B or C.
