Abstract
A nanocolloidal platinum dispersion comprising nanocolloidal platinum and a polyacrylic acid salt, the nanocolloidal platinum having an average particle size of 1-5 nm, 90% or more of the nanocolloidal platinum having a particle size in a range of 0.1-10 nm, its production method, and a drink containing such a nanocolloidal platinum dispersion.
Claims10
A nanocolloidal platinum dispersion comprising nanocolloidal platinum and a polyacrylic acid salt as a colloid-protecting agent, wherein said nanocolloidal platinum is capable of removing reactive oxygen species and has an average particle size of 1-3 nm, 90% or more of said nanocolloidal platinum having a particle size in a range of 0.1-10 nm, wherein a molar ratio (R value) of said colloid-protecting agent on a monomer basis to said nanocolloidal platinum is 100-150.
A nanocolloidal platinum-containing drink comprising a nanocolloidal platinum dispersion, which comprises nanocolloidal platinum and a polyacrylic acid salt as a colloid-protecting agent, wherein said nanocolloidal platinum is capable of removing reactive oxygen species and has an average particle size of 1-3 nm, 90% or more of said nanocolloidal platinum having a particle size in a range of 0.1-10 nm, wherein a molar ratio (R value) of said colloid-protecting agent on a monomer basis to said nanocolloidal platinum is 100-150.
