I did a it of googling and I don't think you can buy it in the USA. You can apparently order through the likes of amazon or Westons Health and the cream is shipped from the UK.

The ingredients on the lotion are:

Aqua
Petrolatum
Isopropyl Palmitate
Paraffinum Liquidum
Glyceryl Stearate
Ceteth-20
Hypoallergenic Anhydrous Lanolin (Medilan)
Phenoxyethanol
Methylparaben
Hydroxyethylcellulose
Carbomer
Propylparaben
Sodium Hydroxide
BHT

Not sure about the cream or other emollient products but the website is www.e45.com so you could have a look and take the info to your local pharmacist to see if they know of anything similar. It is widely recommended by dermatologists, doctors and physiotherapists.
