Prevent chemically modified plant extract chemical

[Mike Dewhirst]

AICIS will not accept chemicals which are plant extracts unless it has a proper botanical name and the chemical has not been modified.

The example they give is for an INCI name where there is no CAS name and no IUPAC name ...

Example:
OK - Helianthus Annuus Leaf/Stem Extract
Not OK - Sunflower extract

We are not going to try and detect this.

However, they also say ...

"The plant extract cannot be chemically modified. For example, the chemical cannot be hydrolysed, acetylated or hydrogenated."

Obviously, such chemicals can be introduced. They just need a CAS name or IUPAC name.

This ticket does two things:

1. Refuses to consider proper botanical names because that requires a properly qualified human scientist - which the software is not. Or at at least, not yet!

2. Makes it an error if
   • Biological chemical is True
   • There is no entry in CAS name
   • There is no entry in IUPAC name
   • One of the above three example words (eg., hydrogenated) appears in INCI name

We can add other named processes to those three examples if necessary.
