Hello and good morning!
I currently have polysorbate 80 but I am looking into buying Peg 40 hydrogenated castor oil. I need an emulsifier in an oil to water facial cleanser. (20:80 oil to “water.” “Water” being rose water/aloe Vera/witch hazel.) I have read Peg 40 hydrogenated castor oil is preferred over polysorbates in the cosmetic making community.
Do you think this is true based on how I plan to you use it? Can you advise the recommended usage rate? Also, Would vegetable glycerin aid the emulsifier in this situation?
I was looking into calculating HLB here:
And I can understand the calculating HLB of an oil phase but calculating HLB of a surfactant is confusing me.
Thank you so much for your time and help! Cami
