Stabilizing surfactants in an anhydrous emulsion
Hello all! I’d like to ask for some ideas on this cleanser I’m working on, which contains sodium cocoyl isethionate in a glycerin and oil emulsion.
The formula is basically
10% montanov 68mb
5% polyglyceryl-3 cocoate
5% sodium cocoyl isethionate
The formula comes together well, but white blobs of surfactant separate out very quickly. It stays together for about a minute when shaken vigorously. The emulsion is completely stable when made without the SCI.
I know SCI is generally solubilized into an amphoteric like CMPB, but I find that SCI is easily stabilized with standard emulsifiers in general. It’s just here that it won’t stay homogeneous.
Any tips on getting this stable? Thanks.
