I looked over what you posted and you have a mixture of abrasives and
surfactants and a bluish coloring agent.

Blue tint is often added to plastics to make them look less yellow but
does not improve brightness. Laundry detergents often contain bluing.

The polydimethylsiloxane might improve scratch resistance. It is also
water repellent.

Thanks for looking over the chemistry of the "blue magic" ingredients of
the lens restorer and protective seal.

I, for one, do not believe in "magic" elixers, so, I suspect they all have
essentially the same ingredients so looking at the Blue Magic is probably
almost as good as looking at any other.

While I had never heard of these ingredients below, and while they're in
minute quantities (hence, they may not be meaningful), I did look them up
so I write a summary for the rest of the team to benefit from.

CI 77007 seems to be a deep blue pigment

Pluronic F seems to have a bunch of numbers after the F, as shown here
https://worldaccount.basf.com/wa/NAF...Brand/pluronic
where the "Pluronic" is a registered name indicated by "(R)".
[quote=BASF]
The Pluronic® types are block copolymers based on ethylene oxide
and propylene oxide. They can function as antifoaming agents,
wetting agents, dispersants, thickeners, and emulsifiers."

Argilla seems to be my old friend Bentonite, of which I have plenty that a
well driller gave me years ago for poison oak.
https://en.wikipedia.org/wiki/Bentone_34
"CAS No. 1340-68-7(Bentone)" with synonyms of
arcilla blanca; argilla alba as described here

The Argilla (aka Bentone) is used to thicken greases:

Neodol seems to be an ALCOHOL ETHOXYLATE surfactant/emulsifier whose
precise mix of chemicals depends on the number after the word.
http://s08.static-shell.com/content/...eodol-25-5.pdf
Like the "Pluronic F" stuff, there are a billion mixes made by Shell.
http://www.surfachem.com/neodol-91-6
where it's described as a short-chain (C9-C11) alcohol with 6 moles of
ethylene oxide.

So those 4 mystery ingredients (admittedly in small quantities) are
1. blue pigment (CI 77007)
2. surfactants/emulsifiers (Pluronic F & Neodol)
3. thickening agent (Argilla)
