Your favorite "natural" emulsifier for a low viscosity day cream?

I am leaning toward trying sucrose stearate, especially since it is cold process (not essential), but I am curious to hear what else the Forum would recommend, and for what reason?  I will probably be using about 8% oil content.  Thank you.

    Sucrose Stearate will not give you any viscosity build ... your emulsion will be water-thin.  If you are looking to formula a cream, you'll need a companion emulsifier or thickeners to build viscosity.  SS is a good emulsifier.

    A little confused with the terms 'low viscosity' and 'cream' in the same sentence....

    But I make a delightful facial cream with Montanov 202 and GSC.

    I always add a twist of Aristoflex and a sprig of Carbomer, but maybe that won't fit your 'natural' definition.

  • I find that potassium cetyl phosphate is reliable and versatile, though the process can be less straightforward.

    I am looking to make something fairly watery:  a light, daytime, low viscosity facial emulsion that can easily be used in a pump container.  Maybe "cream" is an oxymoron.

    Does anyone know of any negatives (downsides) to using sucrose stearate (other than price and difficulty to find)?  And how would this compare to using GSC as sole emulsifier?  Thank you.

    Sucrose Stearate is a good choice if you are looking for a water-thin emulsion.  But, it may or may not be sufficient solo to form a stable emulstion.  You have to play with it and if it does not work solo, pair it up with another emulsifier.
