W/O or O/W?
This is an ingredient list for a ‘revitalising cream’ it seems to be using a W/O emulsifier (Polyglyceryl-2 Dipolyhydroxystearate) as the primary emulsifier but I can’t really see a high HLB emulsifier to complement it. So would this be classed as a W/O emulsion?
Ingredients: Aqua (Water), Dicaprylyl Carbonate, Helianthus Annuus (Sunflower) Seed Oil, Octyldodecanol, Glycerin, Polyglyceryl-2 Dipolyhydroxystearate, Cetearyl Alcohol, Pentaerythrityl Distearate, Alcohol Denat. (SD Alcohol 40-

It’s not w/o. I can see surfactants and water phase stabilisers. There is no salt, and no oil phase stabilisers, which I would expect to see in w/o. My guess would be that it’s the surfactants that act like high HLB emulsifiers here.

OK, interesting. Thanks for the reply.

Surfactants are nothing more than high HLB emulsifiers
. Where to draw a line between surfactants and emulsifiers is an arbitrary choice and giving that line a precise HLB value is completely nonsensical.Apart from that subtlety, I fully agree with @ngarayeva001. -
another possibility is that the ingredients list is incomplete; the only way to be sure is to examine the product physically
-
Thanks. Physically it feels just like any other moisturiser (not too heavy, etc) which I guess would suggest it’s O/W
-
You can’t guess by the feel of it. There are w/o moisturizers that are gel like and have exceptionally light feel. Sisley Black Rose moisturiser or La Mer eye concentrate would be good examples. W/Os generally repel water although it’s hard to establish type of emulsion this way.

maybe Polyglyceryl-2 Dipolyhydroxystearate is used as a blender for Dicaprylyl Carbonate, Helianthus Annuus (Sunflower) Seed Oil, Octyldodecanol and other oil then trap in water gel.
is it Emma Hardie Midas Touch Revitalising Cream?
i’m curious too how they made it. -
@Pattsi yes it is!
