What Am I? 8

Below I’ve listed the key chemicals found in a common household product.  I’ve drawn the chemical structures of principal components where simple and appropriate; given the E number or CAS number (however tempting Sigma-Aldrich catalogue numbers would be) if no simple chemical structure exists for an additive; and given the chemical formulae or name if neither of the above make sense.  See if you can guess what this is!  If no one gets it within 24 hours, I will post a clue.

C15H31COOC30H61 , CAS  8009-03-8 ,  E903 , KMg9(AlSi3O10)(OH)2  [A clue: this is beeswax, white petrolatum, Canauba wax and mica]

  1. Not quite, body lotion/moisturizer tends to have water as a major component (aqua on the label to be posh). This one doesnt, and it is probably water resistant.

  2. Well generally I’m guessing it’s some kind of cosmetic thing, although does womens’ skin count as a ‘particular type of skin’? I definitely know waxes and mica are popular ingredients in make ups.

  3. Neat series. Found you through your mention in the Nature Chemistry Blogroll. TiO2 is white paint, and the aromatics look like anti-oxidants. I’m thinking sunscreen.

  4. Ok, rethinking…

    Titanium dioxide is white paint, and (it took me a while) but the tricyclic aromatic sugar looking thing seems to be carminic acid, a red coloring agent – provides a red, opaque layer to whatever you’re applying.

    Bismuth oxychloride gives a shimmer and vanillin makes it smell really, really good (my favorite smell), so I’m guessing this is something that the user wants to be seen in a good way (not like sunscreen)

    methyl paraben is a preservative, vitamin e is an antioxidant.

    New guess: lip gloss.
