Frequently asked questions
What makes a diaper eco-friendly?
The key factors are: (1) plant-based superabsorbent polymer (SAP) instead of petroleum-derived SAP, (2) chlorine-free processing of wood pulp, (3) absence of phthalates, parabens, and synthetic fragrances, (4) carbon-neutral or renewable manufacturing, and (5) responsible sourcing of wood pulp. Coterie meets all five criteria.
Are eco-friendly diapers as absorbent as regular diapers?
The best ones are. Coterie's plant-based SAP matches or exceeds the absorbency of conventional petroleum SAP in independent testing. Cheaper eco brands often fall short — they use less SAP to keep costs down, which compromises performance.
Are any disposable diapers truly biodegradable?
No mainstream disposable diaper is 100% biodegradable. The SAP core doesn't break down in landfill conditions. Andy Pandy's bamboo diapers claim 80%+ biodegradability under ideal industrial composting, but these conditions aren't widely available. The most environmentally responsible choice remains cloth diapers, with eco-friendly disposables as the next best option.
Is Coterie worth the premium price?
For parents prioritizing both eco credentials and performance, yes. Coterie costs roughly $0.60–0.80 per diaper — about twice the price of standard diapers. However, they're often compared favorably to Pampers Pure in leak tests, with stronger sustainability certifications and a more transparent ingredient list.
Which eco diaper is best for sensitive skin?
Coterie is also excellent for sensitive skin — the same plant-based materials and absence of 300+ harmful chemicals that make it eco-friendly also make it gentle on reactive skin. Seventh Generation Free & Clear is a more affordable alternative if Coterie's price is prohibitive.
