The invention relates to a method for producing phosphoric acid triesters of formula (I). According to said method, phosphoric acid or a phosphoric acid derivative selected from orthophosphoric acid, tetraphosphoric decaoxide and polyphosphoric acid is reacted with alkoxylated alcohols of formulae (II) R&#x2014;(OA)&#x2014;OH, (III) R&#x2014;(OA)&#x2014;OH, and (IV) R&#x2014;(OA)&#x2014;OH, in the molar ratio phosphoric acid or phosphoric acid derivative to alkoxylated alcohol of 1:2.5 to 1:3.3, at between 200 and 240&#xb0; C. 

Method for producing alkoxylated phosphoric acid triesters

Phosphoric esters comprise The phosphoric esters of the invention are very useful in the manufacture of cosmetic, pharmaceutical and dermatological compositions.

The invention relates to a method for producing phosphoric acid triesters of formula (I). According to said method, phosphoric acid or a phosphoric acid derivative selected from orthophosphoric acid, tetraphosphoric decaoxide and polyphosphoric acid is reacted with alkoxylated alcohols of formulae (II) R&#x2014;(OA)-OH, (III) R&#x2014;(OA)-OH, and (IV) R&#x2014;(OA)-OH, in the molar ratio phosphoric acid or phosphoric acid derivative to alkoxylated alcohol of 1:2.5 to 1:3.3, at between 200 and 240&#xb0; C. 

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

Cosmetic formulations of quaternary ammonium compounds incorporating polyhydric alcohols

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:

Cosmetic formulations of quaternary ammonium compounds free of short-chain alcohols

The invention provides compositions comprising The compositions have low setting points, good solubility and dispersibility in aqueous media and a low flash point.

Cosmetic formulations of having high aqueous solubility and low flash points

The invention relates to spin finishes comprising compounds of the formula ##STR1## in which R.sub.1 is a straight-chain or branched alkyl radical of the empirical formula C.sub.n H.sub.2n+1 or a straight-chain or branched alkenyl radical of the empirical formula C.sub.n H.sub.2n-1 where n is in each case 1 to 9 and R.sub.2 is a straight-chain or branched alkyl radical of the empirical formula C.sub.n H.sub.2n+1 where n is 2 to 16, and also to their use as spooling oils for synthetic fibers.
