Abstract (en)
[origin: WO0061716A1] The invention relates to aqueous preparations in the form of two or more separated, aqueous phases in the idle state, whereby said phases are dispersible together. The preparations have at least one surface-active compound and at least one solved polymer compound and are provided with an accelerated phase separation in the idle state when said preparations contain at least one water-soluble, monovalent or multivalent alcohol with 2-9 C-atoms. In a preferred embodiment, 2-20 wt. % of an ether sulfate or ether sulfosuccinate are contained as a surface-active substance and 2-20 wt. % of ethyl alcohol or isopropyl alcohol are contained as an alcohol. The polymer compound is preferably chosen from polypropylene glycol with molecular weights of more than 1,000 D, hydroxyethylcellulose, xanthan gum, dextrane, sodium hyaluronate or cationic cellulose ethers.
