What Ozark Trail 32 oz Tritan Plastic Chug is made of, ingredients and materials
This bottle is molded from Tritan, a BPA-free copolyester plastic developed by Eastman Chemical as a replacement for polycarbonate. Tritan does not contain bisphenol A (BPA) or bisphenol S (BPS) by design, and it has no intentional coatings or liners that could degrade. The material is rigid, durable, and inherently resistant to hydrolysis, meaning it does not readily break down or leach compounds when exposed to water or typical use temperatures.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Microplastics
While Tritan is heat-resistant to roughly 100°C, repeated or sustained boiling may eventually cause micro-scale degradation or shedding. Risk remains low under typical drinking-bottle use (cold to warm water) but increases if bottle is repurposed for hot-beverage storage.
Source, EPA ↗Durability and degradation over years
Long-term exposure to sunlight, freezing, and acidic beverages (citrus, sports drinks) may cause the plastic to become brittle, cloudy, or weakened after 2-3 years of intensive use. This is not a toxicity hazard but a material failure hazard that may prompt premature replacement.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
BPA & bisphenols
Tritan copolyester is formulated without BPA or BPS. No independent testing on public record has detected these compounds leaching from Ozark Trail Tritan bottles under normal use conditions.
Source, FDA ↗Phthalates
Tritan is a rigid copolyester and does not require phthalate plasticizers. No reported or documented phthalate content in this material class or brand.
Source, ATSDR ↗Manufacturing residues or volatile organic compounds
No public record of off-gassing complaints, odors, or VOC issues specific to this bottle. Tritan formulations typically have low volatile organic compound profiles compared to some polyethylene or polypropylene alternatives.
The full breakdown
The brand's record and disclosure
Ozark Trail, Walmart's house brand, has not published formal material safety data sheets or toxicological certifications for this specific bottle. The brand has not faced major recalls or public safety controversies tied to this water bottle model. Ozark Trail does not disclose PFAS testing or manufacturing practices, but the use of Tritan as a base material is itself a marker of PFAS avoidance, as Tritan does not require PFAS for water or stain resistance.
How it compares in its category
This product sits in the mid-market reusable plastic water bottle category, competing with brands like Contigo, CamelBak, and Hydro Flask. Compared to older polycarbonate bottles or untested generic plastics, Tritan-based bottles carry lower chemical risk. Compared to glass or stainless steel alternatives, plastic always carries residual leaching risk under extreme conditions (prolonged boiling, freezing, or acidic contents), though risk is negligible under normal household use.
If you buy it
Do not fill with boiling water or store in direct sunlight for weeks, as sustained heat can accelerate any trace leaching. Hand wash or use a gentle dishwasher cycle; abrasive scrubbing or high heat cycles are unnecessary and may degrade the plastic over time. Replace the bottle if the plastic becomes visibly cloudy, cracked, or stained after years of use, as these may indicate micro-fracturing. Rinse thoroughly before first use to remove any residual manufacturing compounds.
