  • Well, that’s overdue, but to be honest a lot of dry cleaning solvents are either toxic (Chloroform, Triclor) or greenhouse gasses (1,1,1 Tricloroethane, Freons), and most if not all come from petroleum sources. Unfortunately, we need them, or replacements anyway, for things as varied as whiteout correction fluid, industrial degreasers, and household cleaners. Finding cheap ways to make substitutes (like limonene, lactates, acetals) from natural sustainable sources is a huge challenge.

  • There seems to be some disagreement, but TiO2 (a very white pigment powder) is generally considered safe and has been used in everything from wall paint to toothpaste for decades. A few studies have suggested possible genetic toxicity, but it may be only from the extremely small nano-particle form. Another study suggested lung problems much like asbestos, but that might be from breathing high level aerosol concentrations. All in all, there’s no clear consensus, which seems like a pretty good sign for such a commonly used material, but the jury is still out.
