Medical Grade Silicone

What is Medical Grade Silicone?

Medical grade silicone refers to silicone that meets strict regulatory standards for use in medical devices and implants. It must pass rigorous biocompatibility testing and meet requirements for purity, chemical stability, and absence of harmful additives. The most commonly referenced standards are ISO 10993 biocompatibility testing and USP Class VI certification.

In the context of sex toys, medical grade silicone is used in premium sex toys where the highest level of material purity and body safety is a priority. It is the benchmark that other silicone formulations are compared against, and products made from it can legitimately claim the highest hygiene and safety credentials.

The feel of medical grade silicone is very smooth, velvety, and non-tacky. It is available in a range of firmness levels and has a distinctly premium quality compared to lower-grade silicone blends.

Key Characteristics

• Texture: Very smooth, velvety, and non-tacky
• Flexibility: Variable; from soft and flexible to semi-firm depending on formulation
• Durability: Exceptional; highly resistant to degradation, heat, and chemical exposure
• Weight: Lightweight to moderate
• Temperature Response: Moderate; can be used for mild temperature play

Is Medical Grade Silicone Body-Safe?

Body-Safe

Medical grade silicone is considered the gold standard for body-safe sex toy materials.

Non-Porous: Medical grade silicone is completely non-porous. It cannot absorb bacteria, fluids, or odours, making it the most hygienic flexible material available.

Biocompatible: Medical grade silicone has been tested for biocompatibility and is the same material trusted for long-term implantation inside the human body. Its safety credentials are the most thoroughly validated of any sex toy material.

Chemically Inert: It does not react with body chemistry, lubricants, or cleaning agents. It contains no phthalates, BPA, latex, or other additives of concern.

Platinum-Cure Process: Medical grade silicone is typically cured using a platinum catalyst, which results in a purer, more stable final product compared to peroxide-cured silicone.

Lubricant Compatibility: Compatible with water-based lubricants. Silicone-based lubricants should be avoided as they can affect the surface over time.

Overall, medical grade silicone is the safest flexible material available for sex toys, with no significant safety caveats when used as directed.

Cleaning and Maintenance

Medical grade silicone is straightforward to clean and can be fully sterilised.

• Wash with warm water and mild, unscented soap after every use
• Non-vibrating products can be boiled for up to 10 minutes to fully sterilise
• Can be cleaned in a dishwasher on the top rack without detergent if no electronics are present
• Use water-based lubricants only
• Store in a clean, soft pouch away from other products

Pros and Cons

Pros:

• Highest safety and purity standard available for flexible sex toys
• Completely non-porous and biocompatible
• Can be fully sterilised by boiling
• Free from all chemicals of concern
• Exceptionally durable and long-lasting
• Hypoallergenic

Cons:

• Higher price point than standard silicone
• Not compatible with silicone-based lubricants
• Some brands use the term loosely without genuine medical grade certification

How Medical Grade Silicone Is Used in Sex Toys And Accessories

Medical grade silicone is most commonly found in:

• Premium vibrators and dildos from brands that prioritise material purity
• High-end plugs and insertable accessories where body safety is the primary concern
• Wearable sex toys designed for extended body contact
• Medical and therapeutic intimate devices where regulatory compliance is required

Premium brands use medical grade silicone as a key differentiator in their product positioning. When a brand genuinely uses certified medical grade silicone, it is a meaningful quality signal that goes beyond standard body-safe silicone claims.

Summary of Medical Grade Silicone

Medical grade silicone is the highest standard of body-safe flexible material in the sex toy market. Its biocompatibility testing, complete non-porosity, and freedom from all chemical additives of concern make it the safest flexible option available. It can be fully sterilised by boiling and is compatible with water-based lubricants. The main considerations are its higher price point and the importance of verifying that a brand genuinely uses certified medical grade material rather than using the term as a marketing label. For anyone who wants the very best in material safety, medical grade silicone is the definitive choice.
