When we talk about the many benefits of body-safe silicone for sex toys, we have to talk about how folks can tell the difference between silicone and well, not silicone. There are clues if it’s a translucent material or we can do the flame test, but what if it passes all of that and you still worry? Readers come to me all the time with concerns about a chemical odor despite the material being silicone so hopefully this will lay some fears to rest.

PVC is notorious for having a bad odor right out of the package, due to the plastic softening agents used – phthalates, or not, it seems. Therefore many folks use this odor, or lack of it, to help them determine if something is, or is not, silicone. They believe that a silicone sex toy shouldn’t have any chemical odors and many folks become immediately suspicious of perfectly good silicone sex toys when they open their packaging only to be hit with a chemical scent.

It should also be noted that one way to tell the difference between a really-bad porous material like PVC and a semi-bad porous material like TPR is also odor – generally speaking, TPR/TPE doesn’t have a bad odor. But it could, for many of the reasons listed below. In my personal past experience, the stench of toxic chemicals or cover-up perfumes won’t “air out” in a day or so.  The last time I received a toxic, stinky PVC realistic dildo accidentally for review the smell never abated, never went away. I lasted a week and a half before I took it to the dumpster.

Silicone Does Retain Odors

Because silicone isn’t completely non-porous, it can hang on to odors. We’ve learned this about anal toys (and those odors linger because they’re oil-soluble), but chemical odors that are water-soluble should dissipate a lot easier with a quick wash and some airing out.  The mild soap and water wash (or baby wipes swab, followed up by a “rinse” with a damp cloth for toys not water-resistant) will remove any lingering chemicals – something you should do no matter what with a brand new sex toy – but the most important step is simply letting it air out, free from packaging.

Trapped!

Any of the odor-causing methods below will make the silicone sex toy stink if it still stinks when they package it up. Then, the odors are trapped in the airtight packaging and not releasing until you open it. Items packaged only in cardboard, that are never then shrink-wrapped in plastic, will probably have no-to-low odor because of the cardboard. But if the item is put in a plastic bag and then packaged, or the entire packaging is shrink-wrapped, a chemical odor upon unboxing isn’t something to be immediately concerned about.

The odors can also be trapped, so to speak, from inside the toy, too. Yes, that’s right, the smell is coming from inside the house. Er, toy. How? Why? Well, lubrication of interior parts is one reason, and you can read about that in the next section. Another, manufacturer-specific, reason is the squishy under-layer in Tenga Iroha vibrators. The initial line had a very strong chemical odor that took a long time to dissipate – it reminded me of latex paint. The material under the thin silicone skin was a polyurethane-based squishy foam emitting VOCs. More recent Iroha squishy lines seem to have fixed this. And let’s not forget Lelo’s cringe-worthy scented-on-purpose vibrators – the scent is under the silicone skin, and comes out through the silicone’s pores.

Common Reasons for Silicone Sex Toys Having a Chemical Smell

There are so many factors that can cause a lingering chemical odor. This is actually a lot more common than you may realize. There’s a difference in the curing style and manufacturing process of silicone sex toys between say, the hand-poured RTV platinum-cured silicone that Tantus uses for their dildos and the silicone that goes over vibrators – like HTV (high-temperature vulcanization vs room-temperature).  I’ve read that there can be more curing odors associated with peroxide-cure than platinum-cure, but I don’t know which companies may be using peroxide-cure HTV silicone.

  1. Mold release agent – Basically, PAM for silicone. It’s a lubricant that helps get the sex toy out of the mold. This should get washed off, but cheaper companies may not do a good job of that
  2. Cleaning chemicals – Or, they did get rid of the mold release agent, but didn’t let the product air dry to release the VOCs from the cleaning chemicals
  3. The plastic packaging – if the item is in a plastic molded tray or clamshell, that plastic could be releasing VOCs as well
  4. Glue or dye in the packaging – sometimes instead of a plastic tray, your sex toy is in a foam tray. Maybe it’s dyed a color to match the packaging. Maybe there are multiple layers glued together. Again we have VOCs!
  5. Chemicals released during cure – When talking to numerous vibrator manufacturers they confirmed that during silicone cure a chemical reaction occurs and a strong odor comes with it. It’ll go away with 24-48 hours to air out, and good companies let their products air out before packaging. A cheap company will want to crank production up as much as possible and won’t give their products time to air out.
  6. Lubricants – Not the kind you’ll be using, but the kind used during production. I can’t accurately speculate what any given company would use to lubricate moving parts, but it could be anything from an alcohol-based spray to white lithium grease. If there’s no hard plastic barrier between the greased vibrator guts and the silicone skin of a vibrator, you might be smelling that odor for quite some time. One sex toy that comes to mind is this cheap bendable silicone vibrator – I had one complaint of it smelling so bad that I had to investigate and when I cut it open I noticed a little bit of a machine-shop odor and could tell it was from the lubricant used inside. Since it’s bendable, there was nothing in between the guts and the silicone.

What are VOCs?

Some of you may be wondering – VOC stands for Volatile Organic Compound. When you smell a chemical odor? That’s a VOC. Paint, new shower curtains, sex toys, cleaning products – we can’t escape them. They’re trying to regulate them, but it’s going to be a tough battle. If your new sex toy has a chemical odor, try to let it air out in a non-living-space room *if possible* since many VOCs can cause headaches, or more.

The bottom line? Fear not! A chemical odor doesn’t indicate anything bad on its own. Much appreciation to Vibratex, L’amourose, Doxy and Funkit for answering my questions in my research for this article.

There's No Best Sex Toy

Cadillac of Vibrators. Top of the heap. One to rule them all. Everybody needs one! If you spend enough time on Reddit boards, Buzzfeed or other online mags that talk about sex/sexuality you will soon see posts talking about the “best” sex toy. They give readers no indication of qualifiers, and yet inevitably there will […]

Satisfyer 2 Review

This is my 3rd Satisfyer review in as many days and I feel like the Satisfyer 2’s theme song should be “I Can’t Get No (Satisfaction)”. Due to my love of the Womanizer PRO40, in large part because of the up and down intensity navigation buttons, you would think that I’d be recommending the Satisfyer […]

Satisfyer 1 Review

The cheapest in price, the Satisfyer 1 is battery-powered and simple. The silicone nozzle head is the one that is the most similar to the Satisfyer Pro 2 (and the Womanizer line) – it is large, fits securely over the plastic head guide, and appears to be more comfortable due to its fat shape and […]

Satisfyer Pro Penguin Review

The Satisfyer Pro Penguin is cute, I can’t deny it. It could be considered the most “femme” of all the Satisfyer designs, and it’s also the smallest. As I write the reviews on the Satisfyer models, and see others rate the Pro Penguin favorably, I wonder if I’m perhaps being too picky. And then I […]

Tiny Review: Tenga Iroha Yoru

This looks like a really strange sex toy. I know. As I was using the Iroha Yoru during testing I found myself wondering what I was thinking when I requested to review it. I guess I was thinking “Everybody will be picking the Kushi and Tori, I should write about the Other One, the world […]
