For sunscreen entering the EU and UK, what are the differences in SPF testing standards (ISO 24444) between CPNP and SCPN?
CPNP and SCPN are notification portals, not testing standards. Both require SPF testing per EU regulations. Note that the current ISO 24444 is being replaced; the new version uses a 5 cm application rate, significantly altering SPF values. Verify if lab reports cite the current or the 2025/26 implementation version.
1Not portals but standards
CPNP (EU) and SCPN (UK) are notification tools, not testing methods. Both rely on current EU regulations. Always verify the specific version of the standard used.
2ISO 24444 revision
Current ISO 24444 is being replaced. The new version uses a 5 cm application rate, making SPF values incomparable. Lock the standard version in the contract.
3Labeling constraints
SPF claims require UVA protection values (min 1/3 of SPF). Labeling languages must follow local rules. UK requires a separate UK Responsible Person post-Brexit.
Follow-up questions
- Q:Who is responsible for SPF testing?
- A:Must be commissioned by the Responsible Person to a qualified lab, with results stored in the PIF.
- Q:Can UK and EU SPF data be shared?
- A:Lab data is universal, but compliance is split: separate CPNP and SCPN notifications, plus different local Responsible Persons.
