There are a few ingredients you will need to buy in order to complete your course. The course booklet details everything you need and also has a list of suppliers.
Below are links to some of the ingredients on Amazon, however please note you can source ingredients in many places if you have the time to hunt around.
Check your course booklet to work out the total amount of each ingredient you need to complete the course. If you have a friend who is completing the course, we would suggest buying together to minimise any wastage.

Bicarbonate of Soda
This is one of the key ingredients in bubble bars. Even if you decide to never make a bubble again, you can use it for cleaning or cooking! You will need food grade quality. Don’t forget to work out the total you need for the whole course – check your course book as there are different size recipes.
If you are doing the course with a friend – buy. in bulk together as it usually works out cheaper
Castor oil can be bought from many places. All will be food grade so you just need to work out which recipes you are using and how much to buy.
We have included a link to The Soapery’s Castor Oil as it is is fantastic value for money. If you want to purchase in smaller quantities you can do so, directly from their website. Other brands will be fine and you can get Castor Oil in many places.
SLSA is a key ingredient in bubble bars. There were European shortages in 2021 – but it should now be widely available. Don’t forget to check how much you need and only buy this amount.
It is the most expensive of the ingredients – but you can use it to make bath bombs as well. We use cosmetic wholesalers and are currently buying ours from Soaposh. You can also try other wholesalers such as The Soap Kitchen.
Cocamidopropyl Betaine is also available from wholesalers – so if you are buying SLSA from somewhere like Soaposh or The Soap Kitchen, then you might find it is cheaper to buy this from them too. If not, it is available on Amazon.
Cream of Tartar
Cream of Tartar can be bought in supermarkets, or at food wholesalers, but unless they sell it in large quantities, it is not always cost efficient. Don’t forget to calculate how much need as this comes in different sizes.
Moulds and cutters
Before you buy anything specifically for making bubble bars – have a think about what you might already have. You will need to choose one type of mould or cutter, so there is no need to buy lots. The course covers using moulds, cookie cutters, moon dough cookie press or an ice cream scoop. Think about what you want to create, then see if you have anything you can use at home. We have included a selection, but have not tried all of these.
ou can either buy individually or as a set. One small set will easily cover the whole course – if you are on a tight budget, just try and buy one colour. It must be water based (so it will be liquid).
Remember, you should never use food dye in bubble bars as the formulation is intended for baking and may cause stains in your bath or on the skin.
Essential oils & fragrance oils
There are several places you can get essential oils – but it is probably the one ingredient where you can achieve good economies of scale. To start off, it is probably better for you to choose one oil then buy 100ml of it to cover the whole course. We love essential oils like lemongrass or lavender – as both of these work really well in both soaps and bath bombs.
Alternatively you can buy sets of smaller amounts – which will give you a variety to work with.
