Definitions
- the present invention relates to non-aqueous dishwashing detergents based on non-surfactant, water-soluble liquids which, in addition to builders, optionally contain bleaching agents, bleach activators, enzymes and other ingredients of automatic dishwashing detergents.
- the agents also contain large amounts of nonionic surfactants.
- glycerin is neither mentioned nor suggested in this document. Although the use of bleaching agents and bleach activators should be possible according to the disclosure of this document, the compositions disclosed in the examples are free from these substances.
- European patent application EP 611 206 (Colgate-Palmolive Company) also describes non-aqueous liquid dishwasher detergents containing protease and amylase, which contain 5 to 25% by weight of a polymeric swelling or gelling agent (for example polypropylene glycols), 0.1 to 10 wt .-% hydroxypropyl cellulose polymer and optionally contain polyacrylate polymer.
- a polymeric swelling or gelling agent for example polypropylene glycols
- the agents disclosed in this document also contain large amounts of nonionic surfactants.
- the use of glycerin is also not mentioned or suggested in this document.
- Viscoelastic, thixotropic dishwashing detergents with 0.001 to 5% by weight of surfactant as well as enzymes and an enzyme stabilization system made of boric acid and polyhydroxy compounds are described in international patent application WO93 / 21299 (Procter & Gamble).
- the agents disclosed here also contain 0.1 to 10% by weight of one or more thickeners.
- improved products should be provided within the scope of the present invention which combine high performance with high storage and transport stability.
- the incorporation of bleaching agents and bleach activators should be possible without any problems and good cleaning performance should also be achieved without the use of high amounts of surfactants.
- a high level of performance should preferably also be achieved with amounts of surfactant below 1% by weight or without the use of surfactants.
- liquid dishwashing detergents which are based on a liquid matrix of glycerol and polyethylene glycols which are liquid at room temperature meet the stated profile of requirements.
- the liquid matrix can optionally be supplemented by diols, 1,2-propanediol being particularly suitable.
- the invention relates to liquid, non-aqueous detergent compositions for automatic dishwashing, which, in addition to other detergent ingredients which can be used optionally, a) 20 to 50% by weight of one or more water-soluble builders, b) 1 to 25% by weight glycerol, c) 5 up to 40% by weight of a polyethylene glycol which is liquid at room temperature and d) 0 to 20% by weight of 1,2-propanediol and e) ⁇ 2% by weight of free water.
- free water denotes the water content of the agents, which is not bound in the form of water of hydration and / or constitutional water, ie is present in the agents as a component of the liquid matrix.
- this is 2% by weight or less, preferably less than 1 , 5% by weight, particularly preferably less than 1% by weight and in particular even less than 0.5% by weight, in each case based on the composition.
- detergent compositions characterized by a corresponding content of free water are preferred essentially only in chemically and / or physically bound form or as a constituent of the raw materials or compounds present as a solid, but not as a liquid, solution or dispersion in the compositions according to the invention.
- the compositions according to the invention overall have a water content of no more than 15% by weight, so this water is not is in liquid free form, but is chemically and / or physically bound, and it is particularly preferred that the content of water not bound to carbonates and / or silicates in the compositions according to the invention is not more than 10% by weight and in particular is not more than 7% by weight.
- Water-containing liquids can be used in the preparation of the compositions according to the invention, provided that the content of free water is kept below the limit value mentioned by the addition of an “internal drying agent”, for example a hydratable substance in non-hydrated form.
- Water-soluble builders are used in the compositions according to the invention primarily for binding calcium and magnesium.
- Conventional builders which in the context of the invention are preferably present in amounts of 22.5 to 45% by weight, preferably 25 to 40% by weight and in particular 27.5 to 35% by weight, in each case based on the detergent composition, are present are the low molecular weight polycarboxylic acids and their salts, the homopolymeric and copolymeric polycarboxylic acids and their salts, the carbonates, phosphates and sodium and potassium silicates.
- Low molecular weight polycarboxylic acids for the purposes of the present invention are substances which carry two or more carboxyl functions and have molecular weights below 2000.
- the following acids and their salts fall into this group in particular: tartaric acid, succinic acid, malonic acid. acid, adipic acid, maleic acid, fumaric acid, oxalic acid and in particular citric acid.
