INCI and CAS#
I have a scenario I would like your opinion on:
A MSDS lists Hydrolyzed Collagen with CAS #68410-45-7, however when you enter the CAS# on the EU Cosing Database, it shows up as Hydrolyzed Gelatin. While this is the correct INCI name for the particular CAS#, I was informed that the CAS# can also be cross listed with INCI Name Hydrolyzed Collagen. I’m not very familiar with CAS#s and how it relates to INCI naming conventions, so I would love to hear your two cents on this.
Another question I have is, how do you list these types of ingredients that fit into one category (protein hydrolysates, like Hydrolyzed Collagen has a general CAS # of 9015-54-7, but the EU database lists it as Collagen Amino Acids as the INCI name) on your label so you can be globally compliant?
Thank you for your help!

if in doubt, ask your supplier; most reputable manufacturers have enough regulatory support in place to answer questions like this
also CosIng is by no means a complete or comprehensive source - it’s good if you want to find out if something’s on a banned or restricted list, but there are lots of ingredients on there that don’t have their CAS/EINECS numbers listed on there (as I’ve found out from compiling many safety assessments!)

I’ll add that gelatin actually is collagen, and hydrolyzed collagen actually is a mixture of (collagen) amino acids, so the C.A.S.# likely is the same for all three critters, so to speak.
