Surf Excel — plastic bottles for liquid soap

Hi,

I am a regular customer of your liquid soap. I have to buy a 1.05 l bottle every month. It creates too much of plastic waste. I don't want to switch to powder but i also don't want to add to the already too much plastic waste.
Please use recyclable bottles and it would be great if you can make bigger bottles like of 5 litres or something so comparatively the usage of plastic would reduce and i can still use liquid soap. :-)
