Sulfamic Acid, CAS# 5329-14-6, is a water-soluble compound manufactured through treating urea with a mixture of sulfur trioxide and sulfuric acid, available as White Crystalline Powder. Sulfamic Acid is widely used as cleaning agent of processing equipment. It is widely accepted as safe and high efficient cleaning agent in many countries.
No significant side effects reported.
As Sulfamic Acid is widely known as safe, there is no limit on dosage of intake. However, we still recommend consumers to consult professionals before using large quantity of Sulfamic Acid for long period.
Special groups refer to newborns, children, pregnant and any other applicable vulnerable groups.
There is no evidence that Sulfamic Acid could have any negative effects on these vulnerable groups. It should be safe to use Sulfamic Acid in food for newborns and pregnant. However, we still recommend consumers to consult professionals before using large quantity of Sulfamic Acid for long period in food for newborns or pregnant.
Generally recognized as safe(GRAS) is a FDA designation that a specific substance or ingredient is generally considered safe by experts, and so is exempted from the usual Federal Food, Drug, and Cosmetic Act (FFDCA) food additive tolerance requirements. Sulfamic Acid is considered safe by FDA according to existing data and granted GRAS status.
