preparation example Construction

[0129] In a specific embodiment, the method of preparing the stabilized aqueous silicate composition of the present invention involves stabilization with a minimum of two selected osmolytes. This production method includes, for example, the following steps.

[0130] First, the alkali silicate or silica powder is completely solubilized in a strong alkali hydroxide. Alternatively, solubilized alkali silicates can also be used. A concentrated silicon solution is thus obtained in which the silicon concentration is greater than, for example, 3M Si. Preferably, the pH is increased with the addition of alkaline hydroxide until the pH is greater than 12.5. Next, this strongly basic silicate is diluted in a solution containing a sugar alcohol (eg, glycerol), urea, or a mixture of the two. A clear solution was obtained. Then, a second N-methylated osmolyte is added. At this point, other optional osmolytes may be added. Preferably, a silicon concentration of 0.02M to 1.6M is obtain...

Abstract

The present invention relates to dissolved silicate compositions in which the dissolved silicate is stabilized by at least two selected osmolytes and is therefore bioavailable. The composition and its dilutions are stable over a long period of time and are used in a wide field of applications for the benefit of living organisms such as plants, animals and humans.

Description

technical field [0001] The present invention relates to the field of aqueous solutions comprising silicon in bioavailable form. More specifically, the present invention relates to compositions of osmolyte-stabilized alkali metal silicates, for example, suitable for use in plant fertilizer items or pharmaceutical, cosmetic or nutraceutical formulations, and methods, for example, for the preparation of osmolyte Stabilized alkali metal silicates. Background technique [0002] Silicon (Si) is not found in elemental (metal) form in nature, although it is the second most abundant element in the earth's crust after aluminum (Al). In fact, it has a very strong attraction for oxygen and forms a tetrahedral structure attached to four oxygens in the stable and most dominant form in water as Si(OH) monosilicate 4 . This weak acid exhibits four acid functional groups and exhibits the lowest pKa value of 9.8. This shows that at pH 9.8, 50% of the monosilicic acid is present in the und...
