The invention relates to a cosmetic, optically transparent, stable preparation containing: a) between 0.05 and 1 wt. % of an ectoine or ectoine derivative of general formula (I), in which R<1> represents hydrogen or an alkyl group comprising between 1 and 4 carbon atoms, R<2> represents H, -COOH, -COO-alkyl with between 1 and 4 carbon atoms or -CONH-R<5>, where R<5> stands for H, an alkyl group with between 1 and 4 carbon atoms, an amino acid, a dipeptide or a tripeptide, R<3> and R<4> are identical or different and represent H or an OH group and n represents a number from 1 3; b) between 4 and 15 wt. % of an oil component; c) between 30 and 50 wt. % of one or more co-surfactants; d) optionally between 0.1 and 1 wt. % of a physiologically compatible organic acid; e) optionally up to 10 wt. % care agents and/or vitamins; f) between 0.5 and 1 wt. % preservatives; in addition to g) between 20 and 60 wt. % demineralised water. |
