Is Toothpaste a Liquid or a Solid?

Published in Science 1 min read

Toothpaste is a semi-solid substance.

While it has a thick, paste-like consistency, it exhibits properties of both liquids and solids.

Toothpaste can flow and take the shape of its container, similar to a liquid. However, it also holds its shape and doesn't spread out like a liquid.

This unique characteristic makes toothpaste a colloid, a mixture where tiny particles are dispersed evenly throughout a liquid.

In toothpaste, the solid particles are suspended in a liquid base, giving it its semi-solid texture.
