  Zinc or titanium oxide in a lip product

  Posted by Ifa on March 3, 2021 at 3:51 pm

  Hi, I am thinking of incorporating zinc or titanium oxide in a W/O lip cream I am formulating (with Olivem 900 AKA sorbitan olivate). What are your thoughts on it? What would be a good percentage to incorporate them at?

  How can I incorporate zinc oxide in my W/O emulsion?

  In the heated water/oil phase or cool down phase? 

  Or must it be pre-mixed in a medium like PG/glycerine?

  It’s extremely tricky. You would need emulsion to be stable and zinc oxide must be coated and you need additional ingredients that help with dispercing pigments (polyhydroxystearic acid, disteardimonium hectorite etc). Depending on the coating, pigment goes to either water or oil phase. The question is, what benefit are you expecting from zinc oxide?

  If you want SPF then go with the coated ones.

  And what are you trying to achieve with the W/O emulsion? I can’t think of a commercial W/O product with a physical sunscreen.
