WHAT DOES IT DO?

 

Phosphoric acid can be used to adjust pH. In our fluoride mouthwash products it is used in conjunction with sodium or disodium phosphate to help maintain the pH, or acidity of the product. When phosphoric acid is combined with fluoride and disodium phosphate it forms an acidulated phosphate fluoride solution as outlined in the FDA’s Anticaries monograph. This solution promotes remineralization and helps prevent enamel dissolution.

 

HOW IS IT MADE?

 

Our Stewardship Model guides us to select ingredients which have been processed in a manner that supports our philosophy of human and environmental health.

 

Phosphoric acid is produced from phosphate rock reacted with sulfuric acid. The phosphoric acid is then purified for use in our products.

 

WHAT ARE THE ALTERNATIVES?

 

For anticaries mouthwash products, with acidulated phosphate fluoride solution, sodium phosphate or disodium phosphate, and phosphoric acid are required in conjunction with Sodium Fluoride per the Anticaries Drug Products for Over-the-Counter Human Use, Final Monograph.1 Tom’s offers both fluoride and fluoride free mouthwash options.

 

IS THIS THE RIGHT OPTION FOR ME?

 

Phosphoric Acid is Generally Recognized as Safe (GRAS) by the FDA to be used as a food substance for human consumption.2
