TPR Silicone is a Myth

“TPR-Silicone”? Silicone blends? NOPE. Not possible.

For quite some time, we used to believe that there was some bizarre “10% rule” where a manufacturer only had to create a sex toy that contained 10% silicone in order to actually call it silicone for marketing. When I learned that there are no regulations, I learned that the “rule” was a myth and companies could be lying about the material. They could use any material, and claim it to be any material. There is nothing stopping them from out and out lying. And then the lies get spread further because the retailers usually have no option but to parrot the information given to them by the manufacturer.

When I first started reviewing in 2008, we (the consumers) thought that silicone blends and “TPR Silicone” was a thing. The manufacturers called it that, the retailers (of course) called it that. In fact, many retailers still do! A google search of that term shows that it’s still being used on many sites. I don’t know, can’t know, which retailer was the first to explain the various materials – Edenfantasys, for all its downfalls, did a service in providing their material safety rating scale which helped educate a number of people about jelly, cyberskin, etc. The material safety was ranked on a scale from 1 to 10. In order to give credit where credit is due, the material safety scale was created by Shanna Katz and someone who went by “Delilah Douglas” on EF.  Sadly though, they still list TPR Silicone as a material. Many new sites model after their material list, and the myth/misinformation perpetuates. Given the drastic decline of Edenfantasys, I highly doubt that there’s anyone there who would care enough to change their information.

How to Tell TPR from Silicone

Ever since I started burning sex toys, I’ve noticed certain traits. For one, jelly and TPR can be completely clear, crystal clear, but silicone can not be. Silicone can be clear, but it is a somewhat “cloudy” clear. TPR and jelly has also a certain feel that you’ll never get from silicone, and an elasticity you’ll not get from silicone. So if something is crystal clear and can stretch to fit around your ankle? That cock ring is not silicone.

Most often, when I find a sex toy still being advertised as “TPR Silicone” on a retail site, a look at the manufacturer’s site shows that they’re merely calling it TPR. It’s hard to say who is to blame for the inaccurate listings…..did the manufacturer wise up and the retail store hasn’t made changes to the listing? Or is the retail store trying to fool you? Information changes, so what we used to believe as fact is no longer, and when this old, incorrect information still persists, the myths persist.  Sites like this are not out to purposely misinform, but I hope that the information given will be changed as more is learned about these materials and the truth. Information changes, so what we used to believe as fact is no longer, and when this old, incorrect information still persists, the myths persist. 

The Confirmation – TPR Cannot be Blended

I have a few industry friends I can turn to for further investigation when I get one of my hunches, and this was no exception. I can’t name names nor say anything about my “informant” but they work with materials and and have worked for a few large sex toy manufacturing companies. They confirmed for me that it is not possible to blend TPR/TPE with silicone. They’re different materials, and simply cannot be “blended” to create one material type.  They said that one could, technically, layer the TPR and silicone, so that the silicone layer is what is seen by the consumer, but it’s a stretch and it’s very expensive to do so – therefore that negates the whole reason for it. This person reiterated what I’ve suspected, which is that “a lot came from [earlier in the industry] when silicone started to become popular and some were trying to pass it off by saying TPR/TPE silicone”.

Once Again I Lash Out at Screaming O for their “SEBS Silicone” Claims

I decided to dig deeper because of the material naming discrepancies that I still sometimes see; one culprit as mentioned above is Screaming O. I’ve burned their cock rings that they claim are made of a “material” called SEBS, which they claim stands for “silicone elastomer blend”. Not only can you not even blend silicone with a thermoplastic elastomer, but everywhere else in the chemistry world, SEBS stands for styrene-ethylene/butylene-styrene.  The Screaming O cock rings are extremely stretchy and soft. They’re probably over 80% plasticizers (likely mineral oil). When lit, they burn like Indiana Jones’ torch – hot, bright and resistant to extinguishing from a gust of air. The Screaming O rings were the only thing I’ve burned that I couldn’t extinguish by blowing out, I had to toss them under running water. Silicone doesn’t behave like that. And of course, after being burned, the Screaming O rings left no ash — the hallmark of silicone — just a look of melted plastic.  I can’t tell if the material Screaming O is using truly is this SEBS stuff or if they’re just using that acronym as a made-up term for their made-up material. I’d have to raise funds to get a ring sent to the lab like I did with the Hello Touch to find out for sure. I’m skeptical of their material, though, highly skeptical. Styrene is a chemical that many are side-eyeing pretty hard, and aren’t sure how toxic it could be.  If we’re gonna continue to get all technical and science-y, Screaming O (and other sex toy companies too, like Vibratex) use the term “Elastomer” as a material name, when it’s actually a material type. I’d be willing to bet that when most companies are describing their item as being made of Elastomer, it’s really TPE – thermoplastic elastomer. Wikipedia says it’s “also called” thermoplastic rubber (TPR) so I am not yet sure if there is a chemical difference between TPR and TPE, if they’re the same thing, etc. There are different types of TPEs, but I don’t know if all of those types could be used in the sex toy application. We’ve seen these mystery materials come in a variety of shore strengths, too. The softer they are, the more porous they are, and the more likely they are to break down. There’s a big different in how the TPR like these items behaves vs the TPR of say the Eroscillator. I’ve yet to hear that someone’s Eroscillator attachment melted or started to break down, or got “greasy”. Those attachments have much less softening content, though, too. I’ve tried to contact Eroscillator about the material, but they won’t respond.

The term TPR Silicone is very misleading and very incorrect; people hear “silicone” and think that it’s safe, and non-porous. I’d like to see retailers eradicate the language, and I can only hope that when they’re contacted, they will change the terminology.  If you see a site selling items listed as “TPR Silicone”, please consider contacting them to change the wording.

Disclaimer: I am explaining things in the best way I know how. I’m dealing here in many “facts” that I can’t promise are all 100% accurate – we lack the ability to be super scientific about this. I don’t have a chemist by my side, I don’t have a lab. I’m sharing with you what I think, what I’ve been told, what I am inferring from my own test results thus far, and what my reason and logic is filling in. The information here may change as we learn more–this post is evidence that as the years go by in the sex toy industry, things are changing and past truths are becoming myths.
