PleasureSkin is a registered name for a variation of thermoplastic elastomer made to mimic real skin, so essentialy it is some sort of rubber (just more realistic than other types). Some PleasureSkin products may contain phthlates but some don't, no idea if this does though.
What I do know is that realistic materials like PleasureSkin are very porous, so they cannot be sterilised, should only be used with waterbased lubricants and it's safer to use with a condom on. Also, they do require some maintenance: applying cornstarch after use and cleaning so that the material doesn't become sticky.
Hope this helps. You can also contact customer services, they're very helpful
