I have an organic chemistry project in which I have to get 200 compounds with molecular formulas and structural formulas (line diagrams) I have had some trouble with a couple diagrams/molecular formulas, and need some help.

Does anyone know:
PEG/PPG-18/18 Dimethicone?
PEG-150 Distearate?
Polyquaternium-7?
Cocamidopropyl Hydroxysultaine?
Yellow 5?
if at all possible I would like both molecular formulas and structural formulas.  Thanks.

Dear Phallpdx,

Most of time a good start point is the “NIST Chemistry WebBook” you may find under:

http://webbook.nist.gov/chemistry/

It contains also a Lot of other chemistry & physical Information of the Compounds!
The same for Chemistry-Business Names can be found by “ChemExper Chemical Directory”:

http://www.chemexper.com/

In the “ChemExper Chemical Directory”, if the structural formulas are missing, you got at least company names and addresses, where you have the possibility to ask for.

I hope it may be of help to you!

Good Luck!

I would not have posted this question if I could have found it on any of the sites above, does anyone have any further ideas?

Dear Phallpdx,

SORRY!, if I don’t agree with you!  --
And the evidence is given very easy, as I tested it before I answered you!:

A.)   You are NOT able to find a nicer, more coloured structure formula for YELLOW 5 as on “ChemExper.com”. It tells you also some alternate business names for like: Acid Yellow-23, or Tetrazine.
B.)   Also the “NIST Chemistry WebBook” is telling you the exact structure formula for your PEG.
C.)   For others “ChemExper.com” gives you the molecular formula AND the IUPAC name, and with a little knowledge you are able to draw the corresponding structure formula by yourself.
D.)   For the remaining products you are at least able to find Companies with e-mail addresses which sell/produce it or homolges of it.  (Maybe you have to use a little different “language” as in your replay to get a usable answer.) 

So you may realise, that to think about answers may be of some advantages anyway.
(I never told you, that you will find ALL answers at these places, - lonely!)


Good Luck, anyway!
