Just thought I'd share my findings.
Homebase sell a 9.5% Ammonia the appears to be free of any other substance other than water. I've seen some posts from people that think it may contain some surfacant or soap etc as it does foam a tiny bit when shaken.
In the smallest of the small print it says users can contact challs.com for ingredient lists and advice. Well I emailed them and got the data sheet. I can confirm it is nothing but ammonia and water; so safe for cycling.
