Anhydrous Gel; Improving Feel

I'm developing an anydrous gel as a delivery system for natural plant oils. I'm using HEC and diisopropyl adipate with castor oil or mct oil to form the gel. I find the gel to be sticky and I'd like to get better absorption and a smoother feel; closer to the feel of an oil massage. Can anyone suggest ways to achieve this please? The product is to be marketed as natural.

Thanks,

  • Isn’t HEC a water soluble polymer?

    It depends on the degree of substitution of ethyl. "When the degree of substitution of ethyl is between 0.7 and 1.7, Ethyl Cellulose is soluble in water; while it is higher than 1 .5, it is soluble in organic solvents."


  • What about Xanthan?

    Thanks for your input Catherine. I should have mentioned, its a transparent gel and so xanthan won't work.


  • I would think Castor oil is too thick & sticky, MCT much better but there are other alternatives like Olive & Shea Esters. Lexfeel natural will give a good sensorial. Are you using a humectant?

    I have actually tried MCT oil as well. It works quite well, although still with some tackiness. Lexfeel looks interesting and I've requested a sample. I don't have a humectant in the formula at present, do you have any suggestions?
  • Either Glycerin or Propanediol. Just add it to the water and mix, it will add to the moisturisation. Hope this helps.
