Is syneresis a desirable effect in some cosmetics applications? I have been told yes but I am looking for some examples but I can't seem to find it. Instead I though it was an undesirable effect

    Maybe in a 2 phase liquid products but these these are pretty rare otherwise it has been seen as a flaw only in general.

    Thanks @milliachemist, but for example which product of 2 phase liquid do you have in mind?

    Actually it's more like 2 separated phases e.g. a hair product I have seen where there is an oil phase and a aqueous phase and the emulsifier being omitted to give this typical look in a clear container. 
  • Bi-phase makeup removers are fairly popular.

    I second @milliachemists assertion that syneresis is generally viewed as a negative formula attribute. There are far more formula types that are designed to perform as a uniform systems rather than 2 separate systems.
