Good icy white toner?

[Blossom89]

Hello all, I'm looking for a really good toner for my client who's wanting her hair as white as possible, I'm in the process of converting from wella to rusk. Any advice on these colours would be extremely helpful thanks x

wella KP 10/16 with pastel devloper (2 parts developer with one part colour) is great for people who are level 10 to make them white, as is wella colortouch 10/6. colortouch is the gentler/better lasting option, but its slightly less forgiving,it has to be a true level 10 for 10/6 to work, whereas 10/16 will tone better strong golden level 10. though it will fade faster unless violet shampoo is used

I used to use rusk at work and never found a good icy toner, we usually use 10/16 and pastel to achieve a clean creamy toner
