Sodium Benzoate is White granule or crystalline powder, no savor or a bit benzoic savor. soluble in 2 part of water and in 90 parts of alcohol (95 per cent).Used in medicine, tobacco, plating, printing and dyeing,and as antiseptic, anti-animalcule and antifreezing agent in food.
Sodium benzoate is used as a treatment for urea cycle disorders due to its ability to bind amino acids.[7][8] This leads to excretion of these amino acids and a decrease in ammonia levels. Recent research shows that sodium benzoate may be beneficial as an add-on therapy (1 gram/day) in schizophrenia.Total Positive and Negative Syndrome Scale scores dropped by 21% compared to placebo.
Sodium benzoate is used to treat hyperammonemia.
Sodium benzoate has been shown to halt the progression of Parkinson's in mice.
