Best preservatives for eczema prone skin
I am formulating a hyaluronic acid serum for sensitive skin. What preservatives are safest to use? My eczema lotion from Cereve contains the basic ingredients in PE 9010 but its a OW emulsion and PE 9010 has low solubility in water.

phenoxy is ok - soluble enough water , well > use levels. Cerave hyaluronic acid serum uses it as PE 9010. Add something for fungi.
Can’t address eczema concerns.

I sadly don’t know enough about balancing these preservatives which I know is an issue, if you don’t know, don’t formulate. But I’m working on trying to get funding for school. Right now I have PE 9010, GDL and its a high glycerine formula. But only 30% vegetable glycerine. How much GDL do I need if I use 1% PE 9010? Is there anything else I can use for fungus that is safe for eczema?

Use some sodium benzoate and reduce pH.
