Silica Silylate substite for Hair Styling Powder

Posted by Anonymous on December 10, 2019 at 2:28 pm
Hello all,

I’m trying to replicate the Moisturizing Hair Styling powder formulation on ULProspector, containing:
- 2% VP/VA Copolymer
- 6% Water
- 12% Silica Silylate (Aerosil R812S)
- 80% Glycerin
- Preservative
I had some trouble sourcing Aerosil, and tried to substitute it with Silica Dimethyl Silylate.

Using a kitchen mixer (all I have available) I ended up with a goop, not a powder.

My question is… do you think a proper dissolver would get the correct consistency, or is the main problem that I’m using Silica Dimethyl Silylate instead of Silica Silylate?

Here’s a direct link to the formulation:

Thanks in advance!

VP/VA copolymer comes in several different grades - which one did you use?

you’ll get better and more consistent results using a more hydrophobic polymer, e.g. un-neutralised Amphomer

also, regarding your silica dimethyl silylate, what is the surface area per gram, and how does that compare to Aerosil R 812 S? (the value should be in the technical documents)
