Document Type and Number:
WIPO Patent Application WO/2013/136030
Kind Code:
A3
Abstract:
The present invention relates to powder compositions of a complex between an acid or a corresponding anion and at least one metal or corresponding metal cation, said corresponding anion or acid being selected from the group containing 2- hydroxy-4-methylthio-butanoic acid (HMTBA), methionine, aspartic acid, alginic acids, pectinic acids and the corresponding anions, and said metal or metal cation being divalent or trivalent. The particle includes an amorphous fraction, the mass of which represents at least 50%, specifically at least 70% and more specifically at least 90% of the total mass of the particle, said particle being substantially free from non-complexed anion or acid and non complexed metal cation or metal.
