September, 2002 To Clariant:
Recently I was looking for information on Tri(laureth-4)-phosphate [C12H25(OC2H4)3O]3PO a phosphoric ester based on an ethoxilated lauryl (=C12) alcohol This is the chemical & the formula is correct;
the CAS Nr I gave previously was for phosphoric acid, dodecyl ester CAS Nr 12751-23-4
NOT the same chemical
If tri(laureth-4)-phosphate has no CAS Nr would that mean it is unregulated or not approved for use?
If your company is not the manufacturer, do you know who is? *
In 1989 CECA Company manufactured inipol EAP 22 & used this ingredient plus 2-butoxyethanol * CAS Nr 111-76-2C6H14O2/CH3(CH2)2CH2OCH2CH2OH 10-12% of product by weight
plus Oleic acid - primary ingredient CH3(CH2)7CH=CH(CH2)7COOH (Today's CAS Nr = 112-80-1 ...does it match?)
plus Urea NH2-CO-NH2 (Today's CAS Nr = 57-13-6...does it match?)
Is it possible to have the help of an expert chemist and a toxicologist to know the effect on workers? ... when not heated?
.... when heated to 100 degrees C or 194 degrees F? (MSDS Didn't say anything about heating; later reports do)
How would the above listed ingredients react with each other? The tri(laureth-4) phosphate, you say is not a stand-alone chemical... so possibly it will have reacted with 2-butoxyethanol? There is such a chemical as Tributoxyethylphosphate (TBEP) The fact that today's inipol EAP 22 uses a simplistic instead of complex phosphate, could be an indication of problems... overkill, mind you, that may have put workers at even greater risk than first thought. Do you have a recommendation? Sincerely, Margaret - Valdez, Alaska
PS Exxon cautioned that product could be absorbed through skin; * not to breathe vapors... also to keep product out of sewers and watercourses by diking or impounding & keep out of extensive land areas.
Inipol EAP 22 is said to be 100% soluble in water at 77 degrees F (Maybe so; maybe not?)
Doesn't sound like inipol EAP 22 should be used, does it? |
