Tablet for fluoridating potable water
A tablet for use in fluoridating potable water supplies in small municipalities and single point well systems. The tablet preferably contains sodium fluorosilicate, hydrogenated cottonseed oil, and magnesium stearate. The tablet is fed into a dispersal system into the water supply. In systems that treat approximately 150,000 to 600,000 gallons of water per day, the tablet will provide a target fluoride concentration between 0.5 and 0.7 ppm (mg/L).
1. A tablet for use fluoridating municipal water sources, the tablet comprising:
88.0 percent by weight of sodium fluorosilicate;
11.5 percent by weight of binder; and
0.5 percent by weight of punch release agent.
2. The tablet of claim 1 wherein the binder is selected from the group consisting of: hydroxypropylcellulose and hydrogenated cottonseed oil.
3. The tablet of claim 1 wherein the punch release agent is selected from the group consisting of: magnesium stearate and calcium stearate.
4. The tablet of claim 1 wherein the binder is selected from the group consisting of: magnesium tearate, calcium tearate, starch, hydroxypropyl cellulose, and sodium alkylnaphthalenesulfonate.
5. The tablet of claim 1 wherein the punch release agent is selected from the group consisting of: hydrogenated vegetable oil, hydrogenated cottonseed oil, starch, hydroxypropyl cellulose, and sodium alkylnaphthalenesulfonate.
6. A tablet for treating municipal potable water sources, the tablet comprising:
sodium fluorosilicate in an amount of from about 80.0 wt. % to about 88.5 wt. %;
the sodium fluorosilicate acting as a water fluoridation chemical;
hydrogenated cottonseed oil in an amount from about 11.0 wt. % to 20 wt. %;
the hydrogenated cottonseed oil acting as a binder.
7. The tablet of claim 6 , further comprising:
a punch release agent in an amount from 0.1 wt. % to about 1.0 wt. %.
8. The tablet of claim 7 , wherein:
the punch release agent is magnesium stearate.
9. The tablet of claim 7 , wherein:
the punch release agent is calcium stearate.
10. A tablet to provide enhanced dental benefits to small municipalities by increasing fluoride ion concentration in a water supply, the tablet comprising:
sodium fluorosilicate;
a binder; and
a punch release aid.
11. The tablet of claim 10 , wherein the sodium fluorosilicate further comprises an anti-caking agent.
12. The tablet of claim 11 , wherein the anti-caking agent is sodium alkylnaphthalenesulfonate.
13. The tablet of claim 10 wherein the binder is selected from the group consisting of: hydroxypropylcellulose and hydrogenated cottonseed oil.
14. The tablet of claim 10 wherein the punch release agent is selected from the group consisting of: magnesium stearate and calcium stearate.
15. The tablet of claim 10 wherein the binder is selected from the group consisting of: magnesium stearate, calcium stearate, starch, hydroxypropyl cellulose, and sodium alkylnaphthalenesulfonate.
16. The tablet of claim 10 wherein the punch release agent is selected from the group consisting of: hydrogenated vegetable oil, hydrogenated cottonseed oil, starch, hydroxypropyl cellulose, and sodium alkylnaphthalenesulfonate.
