  • Emulsifying Lipids in Water Serum: Need Expert Insights

    Posted by DIYLexa on December 4, 2023 at 2:55 am

    How can I effectively mix 1-5% lipids (like squalane or castor oil) into a serum with high molecular weight hyaluronic acid, glycerin, and propanediol, ensuring it’s stable and emulsified? I wish for the emulsion to be clear, if possible, but it’s not a must.

    Note: I’m using Zinc PCA, which often disrupts emulsions above 0.3% concentration. However, I’m open to removing it if necessary. The serum works well but adding 2-3% squalane improves its feel and absorption, yet it doesn’t blend well. Any suggestions?

    Maybe you can use a solubilizer with a suitable polymer like sepimax zen if the percentage is low. If not just use a normal emulsifier if it’s really 5%.

      What kind of emulsifier would you recommend I use here? Preferably something thats easy to use. I’m also afraid it will break because of Zinc PCA (electrolyte)
