Salt in micellar water
Hi all,It is my understanding that micellar water contains low surfactant level as this is a leave on…however, why would a formula like this contain salt? Below is a formula currently in the market, it contains potassium chloride, sodium chloride….thanks in advanceIngredients: Water (Aqua), Hexylene Glycol,Glycerin, Chamomilla Recutita (Matricaria) FlowerExtract, Panthenol, Niacinamide, Sodium AscorbylPhosphate, Peg-6 Caprylic/Capric Glycerides, DmdmHydantoin, Cetrimonium Chloride, TetrasodiumEdta, Citric Acid, Potassium Chloride, SodiumChloride, Iodopropynyl Butylcarbamate -

Are you sure this formula contains micelles? I can’t say I’m 100% sure but I would guess that PEG-6 caprylic/capric glycerides and cetrimonium chloride won’t form micelles (besides that, there’s nothing else in it which would even remotely participate in micelles).
The salts might be in there because the formulator attributes some effect beyond galenic/cosmetic formulation and rheology? Or it’s there to adjust osmolarity in order to avoid a burning sensation when getting into eyes and mouth? -
Cetrimonium chloride will form micelles. http://www.ncbi.nlm.nih.gov/pubmed/20175982
Salt can help change the packing structure of the particles in the product which could help boost stability. It also might be an ingredient that is brought in with another ingredient in production. You could probably make the formula without the salt but I’m not sure.what is the viscosity of the product? They could also be adding salt to reduce viscosity or maybe for some claims purposes.
