AVAILABILITY

AVAILABILITY

Charcoal toothpaste: Abrasive and can ruin enamel, but magnetic towards dirt and oil

Non-Fluoride Toothpaste: Good for those with allergies, fluoride has properties that help clean teeth better

Alternatives

Cheap, $1-7 typically for 1 tube toothpaste made out of these materials

Cost

High, Sold in Pharmacies, Grocery Stores, Convenience Stores, etc.

Availability

Tin: Yes, Fluoride: Yes, Carbon: Yes, Hydrogen: Yes, Oxygen: Yes, Silicon: Yes, Zinc:Yes

Abundance and Cost Effectivenes:

Tin: Around $7-9 per pound, little is used in toothpaste

Fluoride: 13th in Terrestrial Abundance and 24th in Universal Abundance

Silicon: Makes up roughly 25% of the surfaces crust by weight

Zinc: 23rd most abundant element in earth’s crust

Found in

Nature?

HOW IT'S MADE

-Stannous Fluoride (SnF2) is made by evaporating SnO in 40% Hydrofluoric Acid (HF)

-Glycerin is harvested from animal fats and vegetable oils

-Propylene Glycol starts out as Propylene Oxide, if being prepared for something edible. It is heated “in the presence of ion exchange resin or a small amount of sulfuric acid or alkali” resulting in a product with 20% Propylene Glycol.

-Peg-6 is in the PEG family, the 6 representing it’s molecular weight, PEG is a mixture of compounds that have been bonded together.

HOW IT'S

MADE

Toothpaste is generally safe for the environment, factory creation of it doesn’t burn greenhouse gases or expel toxic gases. Though materials that are allowed in toothpaste are listed as being unsafe for aquatic life.
