[Problem] A preparation of forming bubbles of carbon dioxide gas which is put into a micro-bubble generator is realized, unlike a conventional tablet, as a tablet which can retain an ability to neutralize and remove completely chlorine contained in tap water from start of dissolution of the tablet inside the micro-bubble generator to the completion of dissolution thereof, thereby providing a method for producing micro-bubbles of carbon dioxide gas by using the tablet and a device thereof. [Solution] There is provided a method for producing carbon dioxide gas/micro-bubbles mixed water in which a carbonated bathing agent is a tablet which is 7 mm or more both in tablet diameter and tablet thickness, 15 kg or more in tablet hardness, 10 wt % or less in tablet friability and from 5.5 to 9.0 in pH immediately after dissolution of the tablet in hot water and the carbonated bathing agent contains at least one of the following body rendering agents and contains at least one of the following chlorine neutralizing compounds.

A dental product in the form of a solid includes a mineral source. The mineral source includes a source or sources of calcium ions, phosphate ions or both calcium ions and phosphate ions. The dental product also includes a salt of carbonic acid, an acidifying agent and xylitol. The acidifying agent includes at least citric acid and malic acid, wherein the citric acid and malic acid are present in a weight ratio of from 4:1 to 1:1.

The invention provides a powder oral hygiene composition comprising xylitol, a source of carbon dioxide, an acid and an absorbent, wherein the composition has a water surface area greater than 160 m.sup.2/g.
