Prerequisites: Alchemist 4.

You can create alchemical items in powdered rather than liquid form if desired, though powdered acid, alchemist's fire, antitoxin, and the like follow the same rules as alchemical liquids.

In addition, you can infuse powders and liquids together into a variety of stable magical compounds, from chemicals to cosmetics, creating magical dusts, elixirs, glues, ointments, pigments, powders, salves, soaps, solvents, unguents, and similar substances (such as silversheen) as if you possessed the Craft Wondrous Items feat. Your caster level is equal to your alchemist level.
