Abstract
The invention relates to cosmetic preparations in the form of gel emulsions on preparations of the O/W emulsion type having a hydrocolloid content. Said hydrocolloids are selected from the group of preparations based on (i) hydroxyethylcellulose, (ii) xanthan gum, (iii) carbomer. Said preparations further contain (iv) one or more lipids, (v) one or more non-ionic and/or anionic emulsifiers with HLB values between 8 and 16, the overall content of the emulsifiers not exceeding 1.5% by weight.
