Solubilizers / Surfactants for 95% Tocopherols In Aqueous Serum Formulations

Posted by MarkBroussard on November 3, 2014 at 10:48 pm

I am tinkering with a CE Ferulic Serum. I have been using Laureth-23 (3g) in 1,3-Propanediol (20g) with a touch of Glycerine (1.5g) to solubilize 95% Tocopherols (1g). But, I am looking for alternatives to Laureth-23 (which works wonderfully) for a PEG-free formulation.

Any recommendations?

Maybe a polysorbate? 20 or 80

Hey Perry,

I tried Polysorbate 80 … no cigar. I also tried Polyglyceryl-10 Laurate … no cigar.

I have seen a couple of other LOI where one did use Polysorbate 80 and another used Alkyl Esters, but my efforts with these two have not worked. Sometimes, you either know the “trick” to incorporating an ingredient and sometimes you don’t.

See my other post on Alkly Benzoate Formula Challenge … if you have any ideas?
