Flavour or fragrance blend introductions

[Mike Dewhirst]

The current software (prior to the April 2024 rules) categorises such blends as Reported if maximum concentration of a blend is <= 1% at any annual volume, no end use in vapes and there are no hazards in Health band C or Environment band D and either the blend ingredient(s) is(are) permitted on the IFRA Transparancy list or the identification and concentrations are included in the pre-introduction report.

The new - additional - rule restricts the total volume to 1,000kg if maximum concentration is up to 1% but only 10kg if the maximum concentration is higher (ie., probably not known)

Additionally, it cannot be known to be PBT, carcinogenic, mutagenic or reprotoxic nor endocrine disruptor.

This ticket needs to cope with an unknown maximum concentration by raising an error if volume exceeds 10kg.

The probability is that the hazards are Health band C and Environment band D anyway but if otherwise, that also needs accounting for.

The Rules make abundantly clear that AICIS is interested in both the maximum concentration of the chemical in the blend and the blend concentration at end use - therefore the maximum concentration of the chemical at end use same as for every other introduction!

This is the change made ...

+   if (max_conc <= 1.0 and vol <= 1000) or (vol <= 10) and (not vape):
-   # if (max_conc <= 1.0 and max_prop <= 1.0 and (not vape):

We are leaving the hazard bands as C and D for health and environment respectively because that is what PBT, ECD carc, muta or repro each deliver. They are not going to contain toxic metals (which are the other C and D items) and we don't want them emitting greenhouse gases or destroying the ozone layer either.
