Am making a shampoo and have trialled a few different ways for slightly different results. I am wondering if you guys could help me with the order of process. My ingredients are as follows.
Sodium Lauroamphoacetate 10%
Decyl Glucoside 10%
Cocamidopropyl Betaine 10%
Sodium Cocoyl Glutamate 5%
Xanthan Gum 1%
Shea Butter 1% (I realise people wont like this)
Citric Acid 0.3%
Now I was told to put the surfactants in the water before adding the xanthan gum so it can hydrate all the parts of water. I was also told to add the Sodium Cocoyl Glutamate last out of everything (maybe to prevent bubbles? not sure). I have also seen people put the citric acid in at different times also. I originally just thought it goes in last to adjust the pH then, but have seen it go in beforehand sometimes. I have tried a few different ways but was wondering if you guys could point me in the correct procedure. Cheers.
Another thing, perhaps I should use a new thread for but for those that have used Cocamide MEA flakes, I'm thinking of getting some. Will that work sufficiently enough at say 3% to thicken a shampoo without having to use gums or anything. Have never worked with it and thought I'd ask before buying.
