The present invention relates to a liquid composition comprising A) an organic active ingredient which is sparingly water-soluble and sparingly oil-soluble, in dissolved form, B) an oil which is soluble in water at 20&#xb0; C. to at most 20 g/l, and C) an ionic liquid comprising a cation and an anion as described below. Also provided is a process for the preparation of the liquid composition, where the active ingredient, the oil and the ionic liquid are brought into contact; and also the use of the ionic liquid for increasing the solubility of the active ingredient in an oil.

Composition comprising active ingredient, oil and ionic liquid

Composite elements have the following layer structure:

Composite elements

The invention relates to composite elements comprising the following laminar structure: (i) 2 to 20 mm metal; (ii) 10 to 100 mm polyisocyanate polyaddition products having a density ranging from 350 to 1050 kg/mthat can be obtained by reacting (a) isocyanates with (b) compounds, which are reactive to isocyanates, in the presence of (f) expanding agents, and; (iii) 2 to 20 mm metal.

Composite elements containing polyisocyanate polyaddition products

The invention relates to composite elements comprising the following layered structure: (i) 2 to 20 mm metal, (ii) 10 to 300 mm plastic, (iii) 2 to 20 mm metal, whereby (i) and/or (iii) optionally comprise a closable opening.

The present invention relates to a process for the preparation of CFC-free, flexible polyurethane (molded) foams by reacting

Preparation of CFC-free, highly resilient, flexible polyurethane foams,

In a process for producing foams based on polyisocyanate polyaddition products by reacting isocyanates with compounds which are reactive toward isocyanates and have a molecular weight of from 400 to 8000 in the presence of blowing agents, catalysts and, if desired, chain extenders and/or crosslinkers having a molecular weight of &lt;400, auxiliaries and/or additives, use is made of isocyanates having isocyanurate and/or biuret structures, at least one compound which is reactive toward isocyanates, has a molecular weight of from 400 to 8000 and contains at least 50% primary hydroxyl groups, as catalysts at least one tertiary amine and at least one metal salt plus from 0.5 to 5.3% by weight of water, based on the weight of the compounds which are reactive toward isocyanates and have a molecular weight of from 400 to 8000, and the reaction is carried out at &gt;40.degree. C.
