- Interpretation of results:
- other: No category (CLP Regulation EC no. 1272/2008)
- Conclusions:
- Ammonium stearate is non-irritant for skin (PII=0.62).
- Executive summary:
A skin irritation test was performed on ammonium stearate at a concentration of 100% on rabbits. Test material was applied in a single dose under occlusive conditions. The primary irritation index (P.I.I.) was determined to be 0.62. The substance was non-irritant for skin.
