Definitions
- the present invention relates to improving the solubility of detergents and cleaning agents containing surfactants.
- Detergents and cleaning agents exist in the market in a variety of configurations, both for washing textiles in household and industrial washing, and for cleaning soiled surfaces from objects such as dishes, furniture, carpets or rooms such as kitchens or sanitary rooms to complete Industrial plants.
- the washing and cleaning performance of these agents is largely based on the use of surface-active substances, i.e. surfactants.
- alkylene carbonates as nitrogen-free amphiphile in cleaning agents containing anionic surfactants and cleaning agents for hard surfaces which contain 0.5 to 5% by weight of C 6.14 alkylene carbonate (s) is described in international patent application WO98 / 00418 (Colgate). According to this document, the use of the alkylene carbonates together with the anionic surfactant leads to analphotrophic mixtures which can provide a higher surfactant concentration at the solid-liquid interface.
- the present invention was based on the object of improving the solubility and the rate of dissolution of detergents and cleaning agents containing surfactants, in particular the solubility profile of detergents and cleaning agents which contain nonionic surfactants should be improved.
- the invention therefore relates to the use of 1,3-dioxolan-2-ones in detergents and cleaning agents for improving the solubility of surfactants.
- the 1,3-dioxolan-2-ones to be used according to the invention are usually used in washing and cleaning agents in amounts of 0.5 to 20% by weight, preferably 1.5 to 15% by weight and in particular 2 5 to 10 wt .-%, each based on the detergent and cleaning agent used.
- the ratio of surfactant to 1,3-dioxolan-2-one is between 20: 1 and 1: 5, preferably between 10: 1 and 1: 2 and in particular between 5: 1 and 1: 1.
- 1,3-dioxolan-2-ones to be used according to the invention are cyclic esters of carbonic acid and can be described by the following structure:
- R represents a substituted or unsubstituted alkyl, alkenyl or alkylaryl radical.
- R radicals are methyl, ethyl, n-propyl, iso-propyl and hydroxymethyl and hydroxyethyl radicals.
- Ethylene carbonate is a colorless crystalline compound that melts at 39 ° C and boils at 238 ° C.
- the ethylene carbonate which is readily soluble in water, alcohols and organic solvents, can be produced from ethylene oxide and liquid CO 2 using large-scale syntheses.
- Propylene carbonate is a water-bright, easily movable liquid with a density of 1.2057 "3 , the melting point is -49 ° C, the boiling point is 242 ° C.
- Propylene carbonate is also commercially available at 200 ° C due to the reaction of propylene oxide and CO 2 and 80 bar.
- Glycerol carbonate is accessible by transesterification of ethylene carbonate or dimethyl carbonate with glycerol, with by-products of ethylene glycol or methanol.
- Another synthetic route starts from glycidol (2,3-epoxy-1-propanol), which is under pressure is reacted in the presence of catalysts with CO 2 to glycerol.
- glycerol is a clear, mobile liquid with a density of 1.398 like "3, boiling at 125-130 ° C (0.15 mbar).

- 1,3-dioxolane-2-one extends to detergents and cleaning agents containing surfactants.
- the applicant assumes that the property of the cyclic carbonic acid esters to decompose in an alkaline medium into the diol (or polyol) and carbon dioxide in question has a positive effect on the dissolution and dissolution rate of surfactants.
- Anionic and nonionic as well as cationic and amphoteric surfactants are usually used as surfactants in washing and cleaning agents.

Color transfer inhibitors and corrosion inhibitors.
- the 1,3-dioxolan-2-ones can be used in all detergents and cleaning agents containing surfactants, regardless of their physical state or their further composition.
- Both liquid detergents such as hand dishwashing detergents, glass cleaners, floor detergents and industrial cleaners and liquid detergents for washing textiles can thus benefit from the teaching according to the invention. It does not matter whether these agents have been formulated on a water basis or are to be manufactured as anhydrous agents, for example non-aqueous liquid detergents.
- Solid agents can be in powder or granule form or further compressed, for example extruded or tableted.
- the use according to the invention is particularly advantageous in the case of the highly concentrated and more highly compressed products with high bulk densities.
- solid washing and cleaning agents are hand washing agents, conventional washing powders for use in household washing machines, so-called compact washing agents, machine dishwashing detergents, scouring and cleaning powders or conventional washing and cleaning agents in the form of compact washing and cleaning agent bodies or tablets.
- the 1,3-dioxolan-2-ones have a disintegration-promoting effect on the molded article itself. In molded articles, they therefore not only act as solubility improvers and accelerators for the surfactants, but also as disintegration aids for the molded article itself.
- Another object of the invention is a process for the preparation of detergent-containing detergents and cleaning agents which improve solubility, in which 1,3-dioxolan-2-one is used in amounts of 0.5 to 20% by weight, preferably 1.5 to 15% % By weight and in particular from 2.5 to 10% by weight. each based on the detergent and cleaning agent, inko ⁇ oriert in the agent. by introducing the 1,3-dioxolan-2-one (s) into the compositions via a mixture with at least one surfactant.
