TPE and TPR: the subjects you were taught the wrong way

Behind the pretty packaging of your sex toy often lies a piece of information that no one tells you clearly: the material it is made from. Thermoplastic elastomer (TPE) and thermoplastic rubber (TPR) currently account for a large share of the materials used in the pleasure industry—notably because they allow for ultra-soft textures at affordable prices. But here is what is often omitted: these materials are porous. In concrete terms, this means that bacteria can lodge deep inside them, even after cleaning. A study published in The Journal of Sexual Medicine confirmed that porous toys harbor more microorganisms than their medical-grade silicone counterparts. This is not a reason to panic—it is a reason to be informed.

Because an informed purchase is the best kind of foreplay there is.

Why your toy's material really deserves your attention

Choosing a toy with full knowledge is not perfectionism—it's bodily common sense. The skin and genital mucous membranes are among the most sensitive and absorbent areas of the human body. A porous material used regularly without proper precautions can cause irritation, vaginal flora imbalances, or allergic reactions, especially if your toy contains plasticizers like phthalates, which are still present in some low-end TPE products. Using a condom on these toys is a simple and effective way to create a protective barrier. And if you share your toys with a partner, it is absolutely essential. Knowing what your toy is made of also allows you to maintain it properly, know which lubricants are compatible—oil-based lubricants degrade TPE—and extend the life of your toy. In other words: less spending, more pleasure, the perfect combination.

Frequently asked questions about TPE and TPR

Is TPE dangerous for your health?

Not systematically, but you need to be vigilant. TPE is porous, which makes complete sterilization impossible. Some low-end products also contain phthalates, substances that can potentially disrupt the body. To limit any risk, opt for brands that are transparent about their composition, use a condom, and replace your toy as soon as it shows signs of wear.

How do you properly clean a TPR toy?

Warm water and mild soap are the basics—but they aren't enough to eliminate 100% of the bacteria lodged in the pores. Avoid boiling water and harsh disinfectants, as they damage the material. Dry your toy carefully before storing it, away from heat and light. And above all, never store it with other toys without protection: certain materials react with each other.

My TPE toy smells weird—is that serious?

A strong chemical odor upon opening can indicate the presence of volatile plasticizers, notably phthalates. Air your toy out for a few hours before any use. If the odor persists after several days or if the surface becomes sticky or tacky, it is a sign that the material is degrading. At this stage, it is better to get rid of it—and switch to medical-grade silicone for your next one.
