Re: Oil and water. Is alchohol technically an emulsifier? What is the
difference between a "solubilizer" and an emulsifier if any?

Clarification of Question by c12719-ga on 23 Aug 2005 09:21 PDT

The word "solubilizer" isn't found in most chemical dictionaries. In
the case of Astrazeneca vs Mutual Pharmaceuticals the definition was
found to be that a "solubilizer" "...encompasses three types of
chemicals: surfactants, co-solvents, and complexation agents." I'm
familiar with these three terms. By this definition, it would seem
that "emulsifier" would be considered a "solubilizer" too, would it
not? My question is wheather the two terms are synonymous and if
alcohol could then be considered a "solubilizer". I'd like a chemist
to answer. Can water be considered to be truly "dissolved" in oil
under any circumstances?

Definitions from dictionary.com:

solubilizer - An agent that increases the solubility of a substance

emulsifier - To make an emulsion

emulsion - A suspension of small globules of one liquid in a second
liquid with which the first will not mix: an emulsion of oil in
vinegar



So there is quite a difference between the two. A solubilizer will
increase the solubility of a substance while an emulsifier is
something that makes an emulsion.

Hope this helps.

water cannot be considered to be truly "dissolved" in oil
under any circumstances.
