For the purpose of stabilizing thiamine in various dry preparations and in order to find out the relationship between properties and stability of various thiamine salts, scores of thiamine salt preparations, with different solubility in water and acidity, were manufactured. The solubility of such solutions, preparations and stability of simple aqueous solution of each amine salt were examined and it was found that in a solution, its pH was the chief factor in the hydrolysis and oxidative decomposition of the thiamine salt. Acid salts were stable and neutral salts were generally unstable.
