The materials that touch your most sensitive skin deserve more scrutiny than almost anything else you own. Yet intimate products have historically been one of the least regulated categories out there, and labels like "body-safe," "premium" or "skin-like" can mean almost anything. Here's what you need to know to choose well.
What is silicone, exactly?
Silicone is a flexible, rubber-like material built on silicon and oxygen. It's prized across healthcare, from tubing to prosthetics, because it's stable, durable, heat-resistant and doesn't readily react with the body. In intimate products, silicone is widely considered the gold standard material.
What does "medical-grade" add?
"Medical-grade" refers to silicone produced to a higher purity standard, the kind of material suitable for applications that come into contact with the human body. In practice, for you, it means:
- Non-porous. No microscopic pores for bacteria to hide in, so it can be properly cleaned.
- Phthalate-free and latex-free. No plasticizers that are under scrutiny for health effects, and no latex for those with allergies.
- Odorless and stable. It doesn't leach, "sweat" oily residue, or smell like a chemical factory.
- Durable. It keeps its shape and texture through years of use and cleaning.
Every Erotx product is made with medical-grade silicone. It costs more than the alternatives, and we think it's non-negotiable.
The materials we avoid, and why
| Material | Porous? | Common concerns | Can be fully cleaned? |
|---|---|---|---|
| Medical-grade silicone | No | Not compatible with some silicone lubes | Yes |
| "Jelly" / PVC | Yes | May contain phthalates; can degrade and leach | No |
| TPE / TPR | Often | Softer but can harbor bacteria; shorter lifespan | Partially |
| Rubber / latex | Often | Allergy risk; breaks down with oils | Partially |
Porous materials aren't automatically dangerous, but because they can trap bacteria below the surface, they're best used with a condom and replaced more often. Silicone simply removes that worry.
"Silicone blend" is a red flag
If a label says "silicone blend," "silicone-like," "sil-a-gel" or similar, treat it with caution. These terms are sometimes used to describe products that contain only a small amount of silicone mixed with cheaper, porous materials. Real silicone is simply called silicone, and reputable brands are clear about it.
How to spot a quality silicone toy
- Smell: quality silicone has no noticeable odor. A strong chemical smell is a warning sign.
- Feel: it should feel smooth and velvety, never oily, sticky or greasy.
- Transparency: the brand should state the material plainly on the packaging and listing.
- Stretch test: on a non-electronic piece, gently stretching thin silicone shouldn't leave white stress marks, which can indicate fillers.
Softness and safety shouldn't be a trade-off. Good silicone gives you both.
Why Erotx silicone feels so soft
Silicone can be formulated firmer or softer. We tune ours for an ultra-soft, gentle, velvety finish: smooth enough to glide comfortably over skin, with or without lubricant. It's a big part of why our pieces feel premium in the hand and gentle on the body.
Caring for silicone
Medical-grade silicone is low-maintenance, but not maintenance-free. Wash it with warm water and mild, unscented soap, dry it fully, and store it in its own pouch. Our full routine is in How to Clean Your Silicone Toys. And if you use lube, start with water-based; our lube guide explains why.
