What does phthalate-free mean on a sex toy?

Phthalates are chemicals that were commonly added to soft plastics, including older jelly and PVC toys, to make them flexible. Many people prefer to avoid them for toys that touch intimate skin. A phthalate-free label is a good sign, but it does not mean a toy is nonporous. Check the actual material too, since TPE can be phthalate-free and still slightly porous.
