Salicylic Acid: What the SCCS Concluded About Safety in Cosmetics
Salicylic Acid safety summary from SCCS/1601/18: SCCS conclusion, NOAEL, maximum concentration or conditions, and source-linked context.
Salicylic Acid is covered by SCCS/1601/18, an SCCS-family cosmetic safety opinion dated 2018-12-21. The opinion conclusion for this opinion is direct enough for a substance-specific summary: The SCCS considers salicylic acid (CAS 69-72-7) safe when used as preservative at a concentration of 0.5 % in cosmetic products considering its current restrictions in place.
Core Opinion Facts
- Opinion: SCCS/1601/18
- Opinion date: 2018-12-21
- Primary substance: Salicylic Acid
- CAS: 69-72-7
NOAEL Values Cited in the Opinion
The no-observed-adverse-effect data below is shown only from the SCCS source fields for this opinion. It is not a calculated margin-of-safety output.
| Endpoint | Value | Unit | Study context |
|---|---|---|---|
| NOAEL | 75 | mg/kg/day | Not specified |
Maximum Concentration or Conditions
Conditions from the Opinion
The SCCS considers salicylic acid (CAS 69-72-7) safe when used as preservative at a concentration of 0.5 % in cosmetic products considering its current restrictions in place.; Based on the data provided and available literature, the SCCS considers salicylic acid (CAS 69-72-7) safe when used for purposes other than preservative at a concentration up to 3.0 % for the cosmetic rinse-off hair products and up to 2.0 %.
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 Salicylic Acid 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 Salicylic Acid should be treated as the substance hub, while SCCS/1601/18 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/1601/18 actually assessed.
Review Notes
The conservative reading is to keep Salicylic Acid 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 Salicylic Acid and keeps the source handle visible for audit.
