  Solubility properties

  Posted by ssdc on April 6, 2017 at 4:03 am

  hie,
  I am working on solubilizing essential oil in water and i found that when I use different polyglceryl esters it gives different solubility properties. My question would be the solubility properties is affected by the Hydroxyl value of the esters or the fatty acid chain length or both?

  I am currently using a Polyglyceryl-3 esters (HV:900) and Polyglyceryl-4 esters (HV: 750) both with different fatty acids bonded. PG-3 esters gives better results (clear solution when sollubilise in water)

  I’d try to get a hold of some polysorbate-20, ethoxylated OHs, or some PEGs and play with those.

  The substances you exemplify are products of the chemical factory and are far from being natural.

  We are looking for something that is naturally derived

  I think you will be looking for a long time. A very long time.
