The brightest brand equity starts with the right materials.

Toothbrushes are something that most people use twice a day and hardly think about—until they disappoint. The truth is, not all toothbrushes are the same. Manual toothbrushes have been around for thousands of years, but innovation in the market continues.

Brands and manufacturers are constantly challenged by consumers and retailers alike to come up with the next innovation. Consumers want toothbrushes that are durable, affordable, ergonomic, and effective. Retailers clamor for product line extensions and attractive products that fly off the shelves. To meet all these demands, the key is to start with the most capable materials.

At Eastman, we leverage material expertise and extraordinary market insight to manufacture the specialty plastics that meet market demands for chemical resistance to mouthwashes and toothpastes that contain mint oils, as well as clarity, durability, flexibility, and processing ease. With the broadest range of resins in our portfolio, we offer product designers a regiment of polymers that work together and address precise processing needs. Specifically for the toothbrush market, our BPA-free solutions include:
