Abstract
The invention relates to an ultrafine bubble (UFB) generator and a method for generating UFB. The invention also provides an ultrafine bubble-containing liquid and a production method of the liquid. An ultrafine bubble generator is prepared by combining (A) a sophorolipid containing acidic sophorolipid and lactonic sophorolipid in a ratio (mass ratio) of 78:22 to 100:0, (B) a free fatty acid or salt thereof, and (C) a gas generation component.
Claims6
An ultrafine bubble generator comprising a combination of the following (A), (B), and (C):
- (A) a sophorolipid containing acidic sophorolipid and lactonic sophorolipid in a ratio (mass ratio) of 78:22 to 100:0,
- (B) a free fatty acid or salt thereof, and
- (C) a gas generation component,
- wherein ultrafine bubbles are generated by adding (A), (B), and (C) to water to allow (A), (B), and (C) to coexist in the water under atmospheric pressure conditions without introducing gas from outside, and
- the ultrafine bubbles have an average number particle size of 50 nm or more and less than 1000 nm as measured with a dynamic light scattering spectrophotometer.
