Assignee: M Battermann, D Goddinger, T Bösel, C Hartwich and N Fernandes

Cosmetic preparations, in particular hair conditioners, contain at least one imidazoline derivative including at least two long fat groups, and at least two ester oils. The following detailed description of the invention is merely exemplary in nature and is not intended to limit the invention or the application and uses of the invention. Furthermore, there is no intention to be bound by any theory presented in the preceding background of the invention or the following detailed description of the invention. Surprisingly, it has been found that cationic imidazolines of formula Ia, in particular those that have a residue R chain length of at least 20 carbon atoms, and particularly preferably 21 carbon atoms, in combination with at least two cosmetic ester oils, satisfy in outstanding fashion the objects discussed previously for hair care-providing compositions.

In a preferred embodiment, at least one further cationic compound is contained. This further cationic compound is selected from the cationic imidazolines of formula Ib having a residue R chain length from 8 to 18 carbon atoms, the esterquats, the cationic compounds of formula (Tkat2), or the amidoamines and/or the quaternized amidoamines or the cationic polymeric compounds. The obligatorily present ester oils are particularly preferably selected from the esters of carbonic acid with fatty alcohols, in particular selected from the symmetrical esters of carbonic acid with fatty alcohols and/or from the esters of fatty acids with fatty alcohols and/or an ester oil of the structural formula (D4-II). The embodiments preferred according to the present invention contain at least one physiologically acceptable cosmetic carrier and furthermore contain the following ingredients as presented in the respective embodiment. In no case, however, is a silicone contained.
