    Hi
    I’m planning to do a W/O cream but I want to get some inputs before starting it because i hate wasting my materials. I work on my own cost. 
    Can anyone please help?

    Here is my planned formula so far. It needs to be in a thick consistency
    2% Glyceryl  Stearate
    2% Sorbitan Stearate
    4% Polyglyceryl-4 oleate
    2% Lanolin Alcohol

    10% Palm Oil
    4% Cocoa Butter
    6% Avocado Oil
    Thinking about shea butter but really do a lot of ppl are allergic to shea?
    1% C12-15 Alkyl Benzoate
    Thinking about 2% beeswax or thicken?

    50% Water
    6% Glycerin
    0.2% Tetrasodium EDTA

    4-6% Butylene Glycol

    1.5% Optiphen Plus
    1% Caprylyl glycol, ethylhexylglycerin

    Many Thanks

    will get testing by Cosmetic Test Labs.  Just called and I’m waiting for their quote now.

    Sandy, I will predict this will turn out as either an amorphous mess, or into a o/w emulsion. I don’t see this resulting in an inverse phase system.  Lanolin alcohol is a powerful emulsifier all by itself (see every Nivea Cream ever made), but will revert on cooling from w/o to o/w, depending on the oil load. Why can’t you use one of the many nifty alkyl-modified silicone w/o emulsifiers, e.g. Abil EM-90, DC5225-C? Is it because you can’t have any “unseemly” ingredients in your label listing?

    I’m not against silicone at all. I’m new to this and this would be my first experiments in w/o.

    Yes I prefer the blue tin Nivea w/o texture.

    Besides makingcosmectics.com where else can I get w/o emulsifiers? Thanks

    If I add epsom salt like 0.5% would it help? or more wax?

    If you want to prepare Si/w (Silicon in water) type then use PEG-10 dimethicone in combination with Sucrose distearate & if it is just simple w/o then use PEG-30 DIPOLYHYDROXYSTEARATE
    as a w/o emulsifier.

    You need to start out simpler. Try Dow Corning EL-7040 Hydro Elastomer Blend, add water and preservatives.
