Choose from 5 options:
Highest indicative risk is low risk – chemical identity
Guide to completing the ‘Chemical identity’ section of the pre-introduction report for ‘highest indicative risk is low risk and the other types do not apply’ in AICIS Business Services.
Do you know the CAS name or IUPAC name of the the industrial chemical?
Select Yes if you know the CAS name or IUPAC name of your chemical, and then provide that name.
Select No if you do not know the CAS or IUPAC name, but you know the INCI name. You will then be prompted to enter the INCI name for the chemical.
Do you know the Chemical Abstracts Service (CAS) registry number for the industrial chemical?
Select Yes if you know the CAS registry number for your chemical. You must enter a valid CAS number, either with or without the hyphens, otherwise the following error message will appear “CAS registry number must be a valid CAS Number. E.g. 12-34-0 or 12340”.
Select No if you do not know the CAS registry number.
What is the name (or synonym) you use to refer to the industrial chemical?
Enter the names that you use to refer to the chemical.
Is the industrial chemical a UVCB substance (a substance of Unknown or Variable composition, Complex reaction products or Biological materials)?
Select ‘Yes’ if your chemical is a UVCB substance. You (or the person who knows this information), must describe the UVCB substance by including at least one of the following:
- the manufacturing process for the UVCB substance
- raw material sources of the UVCB substance
- carbon number ranges for the UVCB substance
- physical property ranges for the UVCB substance
- biological sources of the UVCB substance
UVCB description is mandatory for introductions in human health exposure band 4, or environment exposure band 3 or 4. If this does not apply to your introduction, you can enter “not applicable”.
Is the industrial chemical a high molecular weight polymer (HMWP)?
See our definition for high molecular weight polymer.
Select 'no' if is not a HMWP.
If you select 'yes', and your introduction is in human health exposure band 4, you must tell us the information in the following 3 questions.
If you select 'yes', and your introduction is in human health exposure band 1, 2 or 3, then type 'not applicable' as your answer for each question.
What is the number average molecular weight (NAMW)? The NAMW is the arithmetic mean of the molecular weight of all molecules in a polymer.
What is the weight average molecular weight (WAMW)? The WAMW is the arithmetic mean of the molecular of all molecules in a polymer that has been weighted according to the weight fractions of the molecules in the polymer.
What is the polydispersity index? The polydispersity index is WAMW/NAMW.
