Ingredients starting with P
Every ingredient carries a PureScore from 0–100 — lower means more concern. Informational, not medical advice. How PureScore works
- PFOSPersistent bioaccumulative toxin; carcinogen; thyroid and immune system disruptor.2Avoid
- PFOACarcinogen; immune system toxin; developmental toxin; persists indefinitely in environment.2Avoid
- Partially Hydrogenated OilContains trans fats; strongly linked to cardiovascular disease.5Avoid
- PTFEContains PFAS; may release toxic particles at high temperatures; persistent in environment.15Avoid
- Peanut OilRefined oil; high omega-6; industrial refining matches soybean and corn oil concern tier20Avoid
- Potassium BromateFlour oxidizer; possible carcinogen; banned in EU, UK, Canada and beyond.20Avoid
- PropylparabenStronger endocrine disruption than methylparaben; sperm count reduction in animal studies.25Poor

- PetrolatumMay be contaminated with polycyclic aromatic hydrocarbons (PAHs); not biocompatible.35Poor
- Propyl GallateAntioxidant preservative often paired with BHA/BHT; possible endocrine activity; limited safety data.35Poor
- Polysorbate 60Synthetic emulsifier; similar gut microbiome disruption concerns as polysorbate 8038Poor
- Propylene GlycolSynthetic humectant/solvent; food-grade is GRAS but petroleum-derived.45Fair
