Are These Silicones Safe and Non-Toxic?

What Does ‘Non-Toxic’ Mean for Silicone Rubbers?

Non-toxic silicone rubbers, like Pure Mould and I–Gum, are certified and manufactured to be safe for general handling. These formulations do not emit strong odours and are free from solvents, making them pleasant and suitable for use in home or studio environments. While they are non-toxic, always review product guidance to understand any specific limitations or handling recommendations.

Using Silicone Rubber Safely

Silicone rubbers for mould making are generally easy to use, with simple 1:1 mixing ratios and little to no odour. Although products such as I–Gum are described as safe to handle even without gloves, it is still wise to keep good ventilation and to follow all provided instructions. Avoid direct ingestion or prolonged skin contact, as with any crafting material.

• Prepare a clean, dust-free workspace
• Use gloves if you have sensitive skin
• Follow the recommended mixing and curing instructions

When This Matters

Choosing a certified non-toxic silicone is most important for those working in small indoor spaces, for hobby use, or if you are sensitive to chemical odours. It is also essential if your finished moulds will be handled frequently or by children.
