Choosing body-safe materials: a plain-language guide

Non-porous is the standard to look for

Medical-grade silicone, borosilicate glass, stainless steel and ABS plastic are all non-porous. They can be cleaned properly and don't absorb fluids or bacteria.

Porous materials and their limits

Jelly, TPR, TPE, PVC and 'realistic' blends are porous to varying degrees. They can't be fully sanitised, they degrade faster, and some historically contained plasticisers people prefer to avoid.

If you use a porous product, a condom over it is a practical way to reduce the concern.

What 'medical grade' actually signals

It's not a regulated term in this category. It usually indicates platinum-cured silicone, which is more stable than tin-cured. Reputable brands will say which curing process they use.

Simple checks at home

Two pieces of pure silicone pressed together won't stick. A strong chemical smell straight out of the box is a warning sign. And a listing that describes material as 'silky' or 'body-safe rubber' without naming the polymer is telling you very little.
