Abstract:
An object of the present invention is to provide an ultrafine bubble generating agent capable of easily generating ultrafine bubbles in a liquid without requiring an ultrafine-bubble generator, a method for producing an ultrafine bubble-containing liquid, an ultrafine bubble-containing liquid produced by the same production method, and the like. The method for producing an ultrafine bubble-containing liquid of the present invention comprises melting ice having a CO2-content rate of 3 wt % or more (preferably a CO2 hydrate).
