About these limits

Caps are conservative interpretations of IFRA 51st Amendment Category 5A (face leave-on), 5B (body leave-on), and 9 (rinse-off). Volatile-load ceilings (1% face, 3% body, 5% rinse-off) reflect BST's stricter dark-skin protocol — irritation on melanin-rich skin heals as post-inflammatory hyperpigmentation, so we formulate well below industry maximums. Always confirm against current IFRA standards for commercial release.
