Homemade bath bombs - where to buy ingredients in London?

[Caitni]

I've a hankering to make bath bombs as Christmas presents for friends and family and they sound quite straightfoward to make and would be lovely (this could be because I'm pregnant so currently addicted to baths ).

Is there somewhere in central London where I could buy the key ingredients (citric acid, dried lavender/camomile, baking soda, lavender and almond oils, a mould plus, and ideally also the plastic/gift bags & ribbons)? Or does anyone have a website they could recommend?

Thanks

Between Boots, the Body Shop, and the supermarket you should be able to get most of the ingredients.

It's pretty easy to get them on Ebay though. I always use magnesium sulfate in my bath bombs and both a 20kg bag from Ebay! Much better than the small tins of Andrews salts.
