Abstract
The current invention relates to a composition comprising a biobased mesoporous silica with a specific surface area, calculated from nitrogen sorption isotherms at liquid nitrogen temperature (77K) by the Brunauer, Emmett and Teller (BET) theory, of at least 300 m2/g, wherein said mesoporous silica is impregnated with a compound. In addition, the invention relates to an oral dosage form, the use of said composition and a method for producing said composition.
Claims18
A composition comprising a silica extract derived from bamboo, wherein said composition is characterized by a dissolution of silicium (Si) of at least 3 wt. % relative to the silicium in the composition, in FaSSIF after 8 hours at 37° C. as measured by ICP-OES.
A method for the production of a soluble silica composition, the method comprising:
- providing a milling composition, said composition comprising a silica extract derived from bamboo in an amount of at least 30 wt. % relative to the composition;
- and
- ball milling said milling composition, thereby obtaining a soluble silica composition.
A method for the production of a soluble silica composition, the method comprising the steps of:
- providing an insoluble composition, said composition comprising a silica extract derived from bamboo in an amount of at least 30 wt. % relative to the composition;
- and
- measuring the specific surface area calculated from nitrogen sorption isotherms at liquid nitrogen temperature (77K) by the Brunauer, Emmett and Teller (BET) theory of said insoluble composition;
- when the specific surface area of the insoluble composition is above 650 m2/g, a calcium salt is added to the insoluble composition in an amount of at least 10 wt. % relative to the weight of the silica extract;
- thereby obtaining the soluble silica composition;
- and
- when the specific surface area of the insoluble composition is below 650 m2/g, said insoluble composition is ball milled thereby obtaining the soluble silica composition.
