- the coating agent is preferably a water-soluble organic polymer, preferably a polymer from the group consisting of polyvinyl alcohol, polyvinylpyrrolidone and cellulose ethers.
- the fracture hardness of the coated detergent tablets is preferably above 60 N, preferably above 80 N, particularly preferably above 100 N and in particular above 110 N.
- the shaped bodies preferably have a cavity in the form of a depression or a through hole, wherein those shaped bodies which are coated on the outer surfaces but not within the cavity are particularly preferred.
- the cavity of the shaped bodies according to the invention is preferably filled.
- Inventive detergent tablets are characterized in that the shaped body comprises a coated surface and a water-soluble or water-dispersible film, wherein the coating and the water-soluble or water-dispersible film are at least partially fused together.
- compositions according to the invention or the compositions prepared by the process according to the invention described above contain washing and cleaning substances, preferably washing and cleaning substances from the group of builders, surfactants, polymers, bleaches, bleach activators, enzymes, glass corrosion inhibitors, corrosion inhibitors, disintegration aids , Fragrances and perfume carriers.
- the agents are therefore usually water-soluble or water-dispersible.
- the detergents and cleaners can contain further ingredients which further improve the performance and / or aesthetic properties of these compositions.
- Preferred agents contain one or more of the group of electrolytes, pH adjusters, fluorescers, hydrotopes, foam inhibitors, silicone oils, anti redeposition agents, optical brighteners, grayness inhibitors, anti-shrinkage agents, anti-crease agents, color transfer inhibitors, antimicrobial agents, germicides, fungicides, antioxidants, antistatic agents, ironing aids , Phobic and impregnating agents, swelling and anti-slip agents and UV absorbers.
