What is Tritan Plastic?

A copolyester developed by Eastman Chemical Company, a specialty materials company founded in 1920 and listed on the NYSE.

A copolyester is a polymer built from more than one type of building block. This particular mix was engineered for three things at once: optical clarity, impact resistance and chemical safety.

It's used in medical devices, laboratory equipment and commercial food service, applications where those three aren't preferences. They're the specification.

Our grade is covered by Eastman FCN No. 1041 and complies with EU Regulation 10/2011.

Originally developed for:

  • High end water bottles
  • Water purifiers
  • Laboratory equipment
  • Medical devices
 

What Tritan gives you

90% Light Transmission

90% Light Transmission

Clarity with no tint. Most clear plastics carry a blue or green cast where the wall thickens. Tritan stays neutral, so a pale rosé reads as pale rosé.

Thin as glass

Thin as glass

Most plastic glasses are thick because the material has to be. Tritan can be moulded thin and still hold its shape, so we can give the glass a rim as fine as glass and a ripple that actually catches the light.

Hundreds of dishwasher cycles

Hundreds of dishwasher cycles

It doesn't cloud like acrylic or yellow like polycarbonate. The glass you unpack and the glass you own years from now is the same glass.

Not all unbreakable materials are created equal.

Is it safe to drink from?

Tritan is free from BPA, BPS and other bisphenols, and has been tested for hormonal activity. Third-party laboratories commissioned by Eastman found no estrogenic or androgenic activity in Tritan or its migration extracts.

The question has been argued. A 2011 study reported estrogenic activity in some Tritan samples; its authors had a commercial interest in a competing material, and Eastman disputes the finding and points to its commissioned third-party testing. We think the balance of evidence is clear, and we would rather you saw the whole picture than a tidy version of it.

  • BPA (bisphenol A)
  • BPS and other bisphenols
  • Lead
  • Cadmium
  • Phthalates

  • Independent laboratory test report, August 2026. Tritan wine glass tested under Commission Regulation (EU) No 10/2011 for overall migration and specific migration (TMCD, phthalates, heavy metals), three consecutive migrations at 70°C for 2 hours.

    Passed

    EU overall and specific migration limits

  • Third-party laboratories commissioned by Eastman tested Tritan copolyesters, their monomers and migration extracts, including a dishwasher simulation (10 days at 70°C), and found no estrogenic or androgenic activity (Eastman, 2012; Osimitz et al., 2012). Manufacturer-funded research.

    None

    Estrogenic or androgenic activity found in Tritan

  • United States (FDA FCN No. 1041), European Union (Regulation (EU) No 10/2011), China (GB 4806.7-2023) and Japan (Positive List), per Eastman's regulatory information sheet for TX1001, March 2026.

    Food-contact markets covered

  • Tritan was introduced by Eastman in 2007 as a BPA-free alternative to polycarbonate.

    2007

    In food-contact use since

  • Commission Regulation (EU) 2024/3190 entered into force on 20 January 2025 and restricts BPA and other hazardous bisphenols in food-contact materials. The main transition period ended on 20 July 2026. Tritan is made without BPA or any other bisphenol.

    2025

    EU bisphenol ban in force

  • Tritan is made without BPA, BPS or any other bisphenol, which is why the EU ban changed nothing for it.

Surface durability governs microplastic shedding

The honest part first: all plastics can shed micro-scale particles.

But shedding isn't random. Shedding is driven by three things: a scratched surface, heat and UV, and wet cycles that break the polymer down. Tritan was built to resist all three. It keeps its surface, it is stable at dishwasher temperatures, and it doesn’t degrade in the wash the way softer plastics do. That is why a Tritan glass is still clear in year four, and it is the same reason it sheds so little.

How you use it matters as much as what it’s made of. Time and heat are what drive migration, and a wine glass sees little of either: a cold drink, an hour, then the dishwasher. That is a very different life from a water bottle refilled for days or a food container in the microwave. In independent laboratory testing, our glass passed the EU overall and specific migration limits.

To keep shedding low, don't leave the glass in high heat for hours at a time.

Isn't more plastic in the world a bad thing?

First off, producing anything takes a toll on the planet. A new product is a new product, whatever it is made of, and we don’t pretend otherwise.

What matters is what happens after it is made. The plastic doing the damage is the plastic designed to be used once. A Djuce glass is designed to be used for years, and to replace the disposable cups that get bought for an afternoon by the pool, on the boat or at the picnic and thrown away the same evening. In those places the alternative was never glass, because glass can’t go there.

Against a glass glass, kept and not broken, the two come out roughly even over a lifetime. That is not where we make a difference. The difference is every cup that doesn’t get bought because a Djuce glass went instead.

One year, one household: items manufactured

Assumes a household that breaks one glass a year, and hosts six outdoor occasions using four cups each. Against glass the difference is small. Against the cups that come out when glass stays home, it isn't.
