If it were any of those, I imagine the stopper would be hazy, unless the refractive index of the matrix were very close to the aggregate. Curiosity abounds, the mind boggles.
Might be a silicone (polydimethylsiloxane) based grease, with various silicone oxides and/or polymers as thickeners. Now I wanna take one apart.

Similarly Faber Castell's Super True Gel refills are stopped by a composite follower. A transparent one, then a white one. Parker's gel refills' follower sometimes leaks and it is messy.
