I believe Edenfantasys goes the conservative route and won't list a product as phthalate free unless it is a material that is completely phthalate free (100% silicone, glass, etc.) or if the company says it is phthalate free on the packaging. Going with a TPE, TPR, or TPR Silicone instead of jelly is a good idea because the material is more likely to be safer (hence the higher safety rating) but there is a chance there are still phthalates. Personally, I wouldn't worry about it since it is not a penetrative toy and the exposure time is pretty limited. Penetrative toys are easy to protect yourself against with a condom, but for stretchy cock rings the option isn't really there. Good question!
