Method for producing oil-in-water emulsions from self-emulsifying gel concentrates

A method for producing oil-in-water dispersions from self-emulsifying gel concentrates, comprising the following steps:

• (a) providing an emulsifier concentrate (A) comprising at least:
• (A.1) 0 to 80% by weight of one more polyols (P);
• (A.2) 0.01 to 99% by weight of water (W);
• and
• (A.3) 1 to 80% by weight of an ionic surfactant (I) and/or a non-ionic surfactant (N);
• each with respect to the emulsifier concentrate (A);
• (b) bringing an oil phase (O) into contact with the emulsifier concentrate (A) in an essentially exclusively laminar flow field in order to obtain a self-emulsifying O/W gel concentrate (G) with an oil content of more than 5% by weight;
• and
• (c) bringing the O/W gel concentrate (G) into contact with water;
• wherein the oil-in-water dispersion is an emulsion and the oil phase (O) is the disperse phase.
