Glycerin
Also known as: glycerol, vegetable glycerin
A common humectant; some natural communities avoid it, while mainstream evidence of enamel 'coating' harm is limited.
01. What it is
What it is
A syrupy humectant that keeps toothpaste from drying out and adds mouthfeel.
02. Why it’s used
Why it’s used
Moisture retention, texture, and formula stability.
03. The concern
The concern
Internet lore claims glycerin coats teeth and blocks remineralization. That claim is popular in natural circles but not strongly established as a clinical consensus.
04. Our take
Our take
We mark glycerin as caution for transparency with our audience, not as a proven toxin. Glycerin-free pastes exist (e.g., some Wellnesse SKUs) if this is your non-negotiable. Do not confuse glycerin anxiety with ignoring whether a paste has a real remineralizing active.
