How to Read This Safety Conclusion

The key point for formulators is the match between the named ingredient, the cited NOAEL, and the SCCS conclusion. A NOAEL is a study point of departure, not a standalone permission to use at any level. The SCCS conclusion and any concentration or product-type conditions remain the controlling context for cosmetic use.

The source also matters because SCCS opinions can be ingredient-specific. The internal ingredient page for should be treated as the substance hub, while SCCS/1514/13 is the opinion-level page for the committee record.

Practical Formulation Takeaway

For a formula review, start with the identity check: confirm the INCI name, CAS number, and opinion reference align with the material in the formula. Then compare the intended product type against the SCCS concentration or condition language above. If the formulation uses a different exposure route, product category, or concentration basis, the SCCS conclusion should not be stretched beyond what SCCS/1514/13 actually assessed.

Review Notes

The conservative reading is to keep tied to this exact opinion. The opinion number, date, NOAEL table, and condition language all travel together. If a later formula review uses a different CAS identity, product type, or concentration basis, the source should be checked again rather than reusing this summary as a blanket answer.

This page is therefore an indexable safety summary, not a replacement for the committee text. It gives search readers the core SCCS facts for Opinion on Parabens - Updated request for a scientific opinion on propylparaben and butylparaben and keeps the source handle visible for audit.
