Question from Patreon: How can I make a shower gel concentrate"
In the September Patreon Q&A, Sally asked: How can i make a shower gel concentrate" I want to be able I want to make a large batch using some sci which takes a long time to melt, then dilute and add a different fragrance when I want say 300 mls of product. Do I just melt and mix the different surfactants using little or no water"
This isn't directed at you, Sally, but I don't understand why people think melting SCI (sodium cocoyl isethionate) is so hard. It isn't. You just need to choose the right surfactant to help dissolve it. You can add some anionic surfactants like disodium laureth sulfosuccinate, sodium methyl cocoyl taurate, sodium cocoyl glutamate, or sodium lauroyl sarcosinate. You could add an amphoteric surfactant like cocamidopropyl betaine or cocamidopropyl hydroxysultaine. Or you could add some non-ionic surfactants like polysorbate 20 or 80, decyl glucoside, lauryl glucoside, or PEG-7 glyceryl cocoate.
My first choice is always cocamidopropyl betaine because it increases the mildness of the surfactant mix! (As a note, I'm calling it cocamidopropyl betaine instead of coco betaine because they are, in fact, two different products. It's a pain to type, but it's a good thing to be accurate!)
When melting SCI in a double boiler, you want to melt it only with the surfactant that can help it dissolve best. (I wrote a post on this a few weeks ago, so check it out here.)
As a note, if you're using the powder - I'm using this version from Windy ...
