I've just had a travel alert from my company about powdered items in hand luggage that I thought some people might find useful.
"Effective from Saturday 30 June 2018, powdered substances such as make-up, protein shakes and baby powder will have to be packed in containers measuring no more than 350ml; all such items will be subject to a secondary search and may be opened. If travellers need to take powdered items in larger amounts, these must be carried as checked baggage."
