Things to Consider
As seen, your shampoo bar may come out differently if you use the same surfactants that come in a different form i.e noodle or pearl. Indeed, if you use a different batch of the same ingredient, you might get odd results or even find you have to alter how you process your product. This goes for any other ingredient in your shampoo bar. In this case it is a good idea to make a small test batch. Sometimes difficulties with formulas could be a result of something that seems very minor, but has a big effect.
You may find that you want to adjust the levels of wet ingredients (waters and vinegar) so that you have more time to play with your mixture. In fact we encourage you to play around so that you get the mix that is right for you.
