fredmartens: Thanks for reading the fine print! I didn't even notice it on the package.
squeakr: If all else fails, I might try the Biotherm product.
Shareholder: Yes, the product I have is in a white opaque plastic packet.
Scotsflyer: It was the Hilton Glasgow on William Street.
Update on internet searches: I've searched for 2 hours using all the key words you good FTers have suggested. The lack of branding of this product is frustrating, to say the least. I'll definitely march up to the front desk and inquire about it on my next trip to the UK. Maybe I can even buy a case off of them! Otherwise, I may just ask all of you to hoard the packets and send them my way -- for a fee!
If any other FTers have more information, please share. Much thanks for the info already provided.
