If your New Year's resolution was to make more environmentally conscious beauty choices, you might want to rethink the items in your tooth-brushing regimen. Colgate has introduced its first ever recyclable toothpaste tube with its Colgate Smile For Good Toothpaste (£4). Most toothpaste tubes today are made from sheets of plastic laminate, sandwiched around a thin layer of aluminium, which is totally unrecyclable. However, the new Smile For Good from Colgate uses High Density Polyethylene (which is used for milk and other plastic bottles), and is widely recyclable.
