I make my own hair formulations using surfactants, etc., (I'm no expert, but I'm learning through an online course, which i need this resolved for) but my daughters like to use this one that is, basically, a soap (INCI potassium cocoate/glycerin). It has a ph of 5.5 and it's really quite lovely and has that typical yellowy-translucency. No need to even condition after it, it's super nice.So a couple of questions on this topic:
I cannot reproduce this formulation as the website says they use "Magnesium Chloride" as their thickener, but I cannot find it for sale in Canada?? Is this the same magnesium chloride that is digestible/edible? When i do a search, i find only supplements.
The only other ingredients after aqua, the potassium cocoate/glycerin and magnesium chloride, are 6 plant extracts, ACV (guessing at this point it would only be a touch of it) and scent. Which leads me to preservation:
Since this is obviously a soap, BUT CONTAINS WATER + GLYCERIN, should it not contain a broad spectrum preservative? They're stating they use "pinus banksiana (pine) extract" as their preservative, and their products have a shelf life of 2 years?? How is this possible? And would the pinus bring down the pH that much to a 5.5??
It's a mystery I'm trying to resolve, as i work through my course to reproduce a product on the market so i can graduate!
Thank you for any thoughts and assistance!
