Non-MG: Castrol Super Clean - ingredients

[Carol <car@texas.net>]

I've received several helpful replies from listers here (Thank you all), so
I post this to "all":

I e-mailed Castrol from their website as to ingredients in Super Clean

They offered to send the list of ingredients" via fax or mail, and sent
this in the meantime:

     Butoxyethanol (5 - 10%)
     Sodium xylenesulfonate (1 - 5%)
     Nonylphenol ethoxylate (1 - 5%)
     Sodium hydroxide (1 - 5%)
     Dye/fragrance (0.1 - 1%)
     Water (balance)

For all you chemists out there....

Which are the offensive chemical compounds? Sodium xyle...te?? 

Just curious....
