Abstract
An anhydrous suspension including a) particles of bioactive glass having a mean particle size less than or equal to 20 μm; and an ester and/or amide with a molecular weight less than or equal to 100,000, and/or an alcohol. A gel obtainable by contacting the anhydrous suspension with water is also disclosed. Applications of the suspension and gel are also disclosed.
Claims21
An anhydrous suspension comprising
- a) particles of bioactive glass wherein the mean particle size of the particles is less than or equal to 20 μm, preferably 10 μm and most preferably 5 μm;
- and
- b) an ester and/or amide with a molecular weight or molecular weights of less than or equal to 100000, preferably 30000, more preferably 10000, even more preferably 3000 and most preferably 1000, and/or an alcohol.
A method for preparing a gel comprising the steps of
- a) wet-milling bioactive glass in a non-aqueous liquid to obtain an anhydrous suspension;
- and
- b) gelling the obtained anhydrous suspension by adding water to the suspension;
- wherein
- i) said obtained anhydrous suspension comprises particles of bioactive glass wherein the mean particle size of the particles is less than or equal to 20 μm, preferably 10 μm and most preferably 5 μm;
- and
- ii) said non-aqueous liquid comprises an ester and/or amide with a molecular weight or molecular weights of less than or equal to 100000, preferably 30000, more preferably 10000, even more preferably 3000 and most preferably 1000, and/or an alcohol.
