Tefal N1150410 Storage containers

Good

Skip until material and coatings are disclosed by brand.

Verdict · Buy with carePolypropylene or polystyrene food storage carries standard plastic leaching risks; Tefal's silent PFAS stance and unspecified resin type warrant cautious use pending material disclosure.

Tefal storage containers lack public PFAS disclosure or third-party verification. Plastic food containers may use PFAS-based treatments, but material type is unspecified. Recommend requesting material details from Tefal before purchase.

What Tefal N1150410 Storage containers is made of, ingredients and materials

These containers are molded from either polypropylene (PP) or polystyrene (PS); Tefal has not disclosed which. PP is thermoplastically stable to ~130°C and generally lower leaching risk; PS is more rigid but softer at lower heat and associated with styrene migration when stressed or heated. Without material confirmation from the brand, you cannot reliably predict temperature tolerance or migration behavior. Both are recyclable plastics but neither is inherently non-leaching under all use conditions.

🧴

Phthalate plasticizers

Polystyrene (if used) may contain phthalates to improve flexibility; PP is less likely but not ruled out without material confirmation. Migration increases with heat, acidic/fatty foods, and mechanical stress.

⚠️

Styrene monomer and oligomers (PS-specific)

If this container is polystyrene, residual styrene can migrate into food, especially when heated or under mechanical stress from stacking or washing. No published data on migration from this specific model exists.

✅

Base material not linked to PFAS

The main material recorded for this product is not one associated with PFAS.

BPA & bisphenols

No BPA or BPS use is documented in Tefal food storage containers. However, unconfirmed resin type means alternative plasticizers or cross-linking agents remain unverified.

Ink or label leachables

The full breakdown

The brand's record and disclosure

Tefal (Groupe SEB) has published no detailed material safety or PFAS disclosure for this product line. The brand maintains PFAS certifications for some cookware ranges but offers no equivalent transparency for food storage containers. No major recalls or contamination incidents are on public record for this specific model. Absence of disclosure is not absence of hazard; it reflects a gap in available safety information.

How it compares in its category

Food storage containers in this price range typically use PP or PS without detailed chemical disclosure. Glass or stainless steel alternatives eliminate plastic leaching but cost more and lack portability. Many competitors also do not specify resin type or disclose PFAS use in gaskets or inks. Tefal's silence on material specifics is common industry practice but limits comparative safety assessment.

If you buy it

Do not microwave or expose to heat above 60°C until material is confirmed by the brand. Hand wash; dishwasher exposure may accelerate polymer degradation. Replace containers if lids crack, discolor, or odor develops; these signal chemical breakdown. Store fatty or acidic foods (oils, tomato sauce, citrus) in glass or stainless steel instead, as these weaken plastic structure and increase leaching. Request material and coating specifications from Tefal customer service before long-term use with hot foods.
