  • Patent number: 8262927
    Abstract: The invention provides a process for working up glycol-containing aircraft deicers, by (1) removing the suspended impurities from the used aircraft deicer, (2) treating the product thus obtained in such a way that the thickeners present therein are no longer capable of gel formation, (3) before or after step (2) establishing a pH of >7, (4) and then fractionally distilling off the glycols.

  • Patent number: 7074395
    Abstract: Cosmetic, dermatological and pharmaceutical compositions containing quaternary ammonium compounds, particularly for hair-treatment, require low setting points, good solubility and dispersibility in aqueous media and a low flash point. It has now been found that such compositions can be formulated with quaternary ammonium compounds and polyhydric alcohols. The invention provides compositions comprising a) at least one quaternary ammonium compound, b) at least one branched alcohol having 8 to 36 carbon atoms or a mixture of at least one branched alcohol and at least one unbranched alcohol having 8 to 36 carbon atoms, and c) at least one polyhydric alcohol having 2 to 6 carbon atoms. The resulting compositions have a low setting point or melting point, good solubility and dispersibility in aqueous media and a low flash point.

  • Patent number: 6919074
    Abstract: Cosmetic, dermatological and pharmaceutical compositions containing quaternary ammonium compounds, particularly for hair-treatment, require low setting points, good solubility and dispersibility in aqueous media and a low flash point. It has now been found that such compositions can be formulated with quaternary ammonium compounds essentially free of short-chain alcohols such as isopropanol. The novel composition comprises: a) at least one quaternary ammonium compound and b) at least one branched alcohol having 8 to 36 carbon atoms or a mixture of at least one branched alcohol and at least one unbranched alcohol having 8 to 36 carbon atoms.

  • Patent number: 6881399
    Abstract: The invention provides compositions comprising a) at least one quaternary ammonium compound, and b) at least one polyhydric alcohol having 5 to 12 carbon atoms. The compositions have low setting points, good solubility and dispersibility in aqueous media and a low flash point.

  • Patent number: 5492650
    Abstract: The invention relates to the use of a microbicidal agent containing polymeric quaternary ammonium borate, obtained by simultaneous reaction of amines of the formula I or II ##STR1## in which R.sup.1 to R.sup.7 and A are as defined in the description, with 1 to 20 mol of ethylene oxide or propylene oxide and 0.6 to 1.5 mol of boric acid, boric acid esters or salts of boric acid, in each case per mole of nitrogen equivalent, as a preservative and/or disinfectant for industrial products and industrial plants.
