What plastic are toothbrushes made of?

Toothbrushes are primarily made from various types of plastics, most commonly polypropylene (PP) for the handle and nylon for the bristles. Polypropylene is durable, lightweight, and resistant to moisture, making it ideal for use in dental hygiene products. Some toothbrushes may also incorporate other materials, such as rubber or bioplastics, for enhanced grip or eco-friendliness.
