What Ashland Chill 2.0 Insulated Stainless is made of, ingredients and materials
The Ashland Chill 2.0 uses food-grade stainless steel as the inner container, which is chemically inert and does not leach metals or BPA into liquids at any temperature. The insulation layer and plastic cap are the only polymer components exposed to contents or handling. Stainless steel construction eliminates the primary leaching pathways found in aluminum, ceramic-coated, or plastic-lined bottles.
What’s concerning
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
Bacterial growth in plastic cap seals
Silicone gaskets and plastic cap threads can harbor mold or bacteria if not dried thoroughly after washing. This is a hygiene issue, not a chemical toxicity issue, but relevant to long-term use.
What’s reassuring
Bare uncoated material
Recorded as a bare, uncoated material with no surface coating or treatment.
Plastic cap polymer breakdown over time
No published data on leaching from Contigo's polypropylene or thermoplastic cap materials at typical beverage temperatures. Standard plastics used in caps are not known to degrade under normal conditions, though mechanical stress (drops, cracks) could theoretically expose new surfaces.
Insulation layer integrity
Double-wall construction typically uses polyurethane or polystyrene foam insulation sealed between steel walls. No hazard is documented if the seal remains intact; damage exposing insulation to beverages is rare in normal use but would not create acute toxicity risks.
Lead
Food-grade stainless steel (typically 18/8 or 18/10 alloy) is not a source of lead or cadmium leaching. Contigo's stainless interior does not carry the risks associated with ceramic glazes or painted coatings.

The brand's record and disclosure
Contigo maintains a general commitment to consumer safety but has published no detailed PFAS or hazardous substance transparency reports. The company does not voluntarily disclose material composition beyond marketing specs. No major recalls or documented safety incidents specific to this model are on public record. The silent stance on PFAS reflects industry-wide caution rather than confirmed concern for this product line.
How it compares in its category
Stainless steel water bottles show lower concern in the insulated bottle category compared to aluminum cores or plastic-lined variants. Contigo's design is typical of mainstream double-wall insulated bottles; it does not use experimental coatings or proprietary polymer layers. Comparable models from brands like Hydro Flask and S'well offer similar material safety profiles at higher price points.
If you buy it
Hand wash the cap and lid gasket regularly to prevent bacterial biofilm in hard-to-reach seams. Do not use in dishwashers if you wish to maximize seal longevity. Replace the plastic cap/lid assembly if cracks develop, as this can expose insulation materials. Stainless steel itself requires no special maintenance and will not degrade from hot or cold beverages.
