A platinum nanocolloid solution comprising platinum nanocolloids and a polyacrylic acid salt, wherein the platinum nanocolloids have an average particle diameter of 1 to 5 nm and wherein 90% or more of the particle diameters thereof fall within the range of 0.1 to 10 nm; and a drink comprising the platinum nanocolloid solution. There is further provided a process for producing the platinum nanocolloid solution, comprising refluxing a solution containing a platinum salt, a polyacrylic acid salt, an alcohol and water, evaporating the alcohol and water from the solution so as to allow part thereof to remain, adding an alcohol and again evaporating the alcohol and water.
L'invention concerne une solution nanocolloïdale de platine comprenant des nanocolloïdes de platine et un sel d'acide polyacrylique, les nanocolloïdes de platine ayant un diamètre moyen des particules compris entre 1 et 5 nm, au moins 90 % des particules ayant un diamètre compris entre 0,1 et 10 nm ; ainsi qu'une boisson contenant cette solution nanocolloïdale de platine. L'invention concerne également un procédé destiné à la production de cette solution nanocolloïdale de platine, consistant à faire refluer une solution contenant un sel de platine, un sel d'acide polyacrylique, un alcool et de l'eau, à évaporer l'alcool et l'eau de la solution pour qu'il en reste une partie, à ajouter un alcool et à évaporer à nouveau l'alcool et l'eau.
