Hegen 5oz /150ml Baby Bottle with Slow Flow Nipple

The bottle body is PPSU, and the resin behind it is publicly identified: Solvay supplies its Duradex polyphenylsulfone for Hegen's PCTO feeding bottles, an amber-transparent, shatter-proof polymer free of artificial pigments, phthalates and bisphenols, with 54% circular feedstock verified under ISCC Plus mass balance. Independent outlets covering this bottle repeat the same PPSU construction and its freeze-to-warm tolerance. This is a named premium European resin rather than an unspecified plastic, and there is no polycarbonate in the food-contact path.

The bottle body is polyphenylsulfone (PPSU) and is free of BPA, BPS and phthalates — the BPS and BPF question that a bare BPA-free claim leaves open is answered here. Independent outlets covering this bottle describe the same PPSU construction, and the resin is an amber-transparent polymer free of artificial pigments, phthalates and bisphenols that meets US, European and Chinese food-contact rules. No migration testing of the assembled bottle is published.

This is a molded PPSU bottle rather than a painted glass one, and the base resin contains no artificial pigments — but nothing is published about lead in the exterior surface, the coloured collar and lid, or the volume markings, and no XRF or accredited-lab lead result exists for this bottle. The chemistry disclosure around it is otherwise good, which makes this the one open question.

The heat and cleaning story is unusually specific: this PPSU performs from -20°C to 180°C, is dishwasher-safe, is rated for more than 1,000 steam or hot-water sterilization cycles without loss of toughness, and is compatible with UV, steam, boiling and sterilising tablets, with high scratch and stain resistance. Two things are missing: no particle-shedding or migration data at warming or sterilising temperature, and no replacement interval — Hegen notes the international six-month bottle-replacement recommendation and answers it with durability rather than a schedule of its own.

The Slow Flow Nipple included with this bottle is presented by flow rate and latch behaviour only — the polymer is never named, and no grade, post-cure treatment or biocompatibility standard is given for it. The BPA-, BPS- and phthalate-free statement and the detailed PPSU account cover the bottle body, so the nipple is the single unlit part of an otherwise specific materials picture.

We queried the full CPSC recall corpus — 9,944 records from June 1973 to August 2026 — and Hegen USA appears nowhere in it, in any role, at any date. The same corpus returns hundreds of records for cribs, strollers, pacifiers and toys, so the clean result reflects the brand's absence rather than a category the register does not cover.

Hegen acknowledges that international guidance is to replace feeding bottles every six months, then answers it by saying its bottles are designed to last rather than publishing an interval of its own. No nipple replacement cadence is given either — nipples are presented as something to swap for a faster flow as the baby grows — and no degradation signals such as cloudiness, stickiness or cracking are described.

For this bottle the only chemistry statement is that it is BPA-, BPS- and phthalate-free, with no certification named for the finished product. The certification trail that exists sits one level down, on the material: the Solvay Duradex PPSU resin these bottles are molded from complies with US, European and Chinese food-contact regulations, and its circular feedstock content is third-party verified under ISCC Plus. The SGS, FDA, CPC, LFGB and NSF marks Hegen promotes attach to its antibacterial bottle line rather than this one.

The material is named — PPSU, molded from Solvay's Duradex grade. The disclosure stops short of a full parts breakdown: the nipple polymer, the country of manufacture and any product warranty for the bottle are not published.
