Carbomer substitute?? (MaxxThix PC-10)
Help! I (like everyone else) am trying to formulate a clear gel hand sanitizer and have no access to the carbomer 940 that we typically use. I’ve received a sample of a replacement called MaxxThix PC-10 (30% 2-propenoic acid, 2-methyl-, polymer with ethyl 2 propenoate and 70% water)
I’m neutralizing with 99% TEA. Formula is supposed to thicken at pH 9 but I’ve added loads more TEA than the vendor recommends and can’t get my formula to thicken. Any suggestions? I’m going to try swapping out some water for glycerin.
67% of 93% pure IPA
2% nonionic surfactant
3.1% MaxxThix (as recommended by vendor)
