Hypoallergenic Claim Boundary
At a glance
Hypoallergenic sounds like a technical guarantee, but in the U.S. it does not have a fixed FDA definition. The directory treats it as a label-interpretation and substantiation question, not as a safety signal by itself.
- Directory role: Allergen-reduction label and consumer-expectation boundary.
- Evidence grade: A/C.
- Claim risk: High.
- Reviewed source title: "Hypoallergenic" — The Claim with a Famous History of Having No Definition.
What evidence can support
- A statement that hypoallergenic has no fixed U.S. FDA definition for cosmetics.
- A comparison between label language and concrete exclusion lists such as fragrance, essential oils, or specific preservatives.
- A source-linked caution that product-level allergen risk cannot be inferred from the word alone.
What evidence cannot support
- A claim that hypoallergenic products are allergen-free.
- A claim that the label guarantees suitability for sensitive skin, baby routines, pregnancy routines, or warmed use.
- A claim that warming a hypoallergenic-labeled product reduces allergen or irritation risk.

Claim boundary

Needs evidence: Any sensitive-user, allergy-reduction, infant-care, pregnancy, or warmed-use suitability statement.
Needs testing: Formula exclusions, allergen profile, patch or tolerance testing, panel definition, and use condition.
Not established: That a hypoallergenic-labeled lotion or oil is suitable for every sensitive user or high-caution routine.
Avoid: Do not imply allergen-free, irritation-free, universal sensitive-skin suitability, infant-care suitability, pregnancy suitability, or warmer compatibility.
