Hydroxycitronellal should not be used such that the level in consumer products exceeds 1%. This is equivalent to 5% in a fragrance compound used at 20% inthe consumer product.This recommendation is based on a no-effect level of 10% in diethyl phthalate y pand on a no-effect level of 2.5% in ethanol/diethyl phthalate in standard Human Repeated Insult Patch Tests (R.A. Ford and A.M. Api, Fd. Chem. Toxic. Vol. 26, p. 921-926, 1988). The RIFM Expert Panel reviewed these data in September 1999 and concluded that no further actions were requiredSeptember 1999 and concluded that no further actions were required.

QRA
• Determination of benchmarks (no expected sensitization induction level, p ,or NESIL);
• Application of sensitization assessmentApplication of sensitization assessment factors (SAF)
• Calculation of consumer exposure• Calculation of consumer exposure (CEL) through product use.
