According to The Register, Greenpeace has issued a warning on the use of certain sex toys:

Greenpeace Netherlands has issued a statement warning sex toy lovers
not to shove the "Spectra Gel Anal Plug" or the "Crystal Jelly Double
Dong" where the sun don’t shine, according to an eye-watering report on
Expatica.

The reason behind the shock advisory is not the possible risk of
ending up in hospital with a dildo stuck firmly up your jacksie and
having to endure the humiliating laughter of medical staff who avail
themselves of the opportunity of grabbing a few X-rays for later
dissemination on the internet, but rather that sex toys apparently
contain "extremely high concentrations of phthalate plasticisers which
allegedly pose a risk to human health and the environment".

Phtalates are indeed banned in the EU for certain uses:

Back in September 2004, the EU Competitiveness Council did indeed vote
for a permanent ban on DEHP, DBP and BBP for use in all PVC toys,
extending a temporary order imposed in 1999. Furthermore, it banned
DINP, DIDP, and di-n-octyl phthalate (DNOP) "from toys and child care
items that children can put in the mouth".

I’m reasonably certain that using such sex toys either on or in the company of children would result in charges under much more serious laws than those banning certain chemicals.
