Sunscreen cosmetic products must meet both consumer expectations and a complex European regulatory framework. Formulating an SPF product involves multiple layers of validation: efficacy, stability, compatibility, labelling, notification — all backed by comprehensive, verifiable regulatory documentation.
At regulatory.cosmeticsinMind, we help brands develop safe, EU-compliant products, from technical formulation to regulatory strategy.
UV filters: authorisations and limitations
Only filters listed in Annex VI of Regulation (EC) No 1223/2009 may be used — and their use must comply with specific rules: maximum concentrations, product category restrictions, or application conditions (e.g., not for use on mucous membranes or pH limitations).
When encapsulated or nanometric filters are used, their status must be clearly declared on the label and supported by additional safety data according to the SCCS (Scientific Committee on Consumer Safety).
Efficacy validation and claims: not just SPF
While SPF measures UVB protection, EU legislation also requires testing to support UVA and water-resistance claims (e.g. ISO 24444 and ISO 24442 protocols). Claims like “broad spectrum” or “effective after swimming” must be backed by solid evidence.
This information must be included in the Product Information File (PIF), which should also detail the full formulation, manufacturing process, toxicological profiles and a safety assessment signed by a qualified assessor.
CPNP notification and traceability
Notification via the EU CPNP portal is mandatory before market placement. It must include product composition, category, final labelling, responsible party details and any nano materials present.
In addition, end-to-end documentary and technical traceability must be ensured — from batch control to storage and transport — under GMP (ISO 22716) guidelines.
Functional ingredients and chemical compatibility
UV filters may degrade or become unstable when combined with certain actives (e.g. acids, antioxidants, high-pH emulsifiers). Using encapsulation systems, SPF boosters (like ethylhexyl triazone) or photostabilizers (e.g. bis-ethylhexyloxyphenol methoxyphenyl triazine) can enhance performance without compromising stability.
Any formulation changes must be updated in the PIF and may require new efficacy or stability testing.
GMP manufacturing and quality control
ISO 22716 outlines documented manufacturing protocols, including microbiological control, process validation, deviation handling and batch traceability. It’s not optional — GMP reinforces legal compliance and protects your brand during audits.
