A fine white powder especially formulated for general laboratory use from effective synthetic detergents, care- fully buffered and blended without use of harsh alkalies or ingredients which affect sensitive skin. Useful for cleaning glassware, porcelain or metal ware. Particularly efficient in removing dried blood, organic residues, and wax pencil marks, and for making soak solution to facilitate freeing frozen ground glass joints, stopcock plugs and glass stoppers.

Contains a surface active (wetting) agent, to facilitate rinsing, which is stable in acids or alkalies, and a sequestering agent which disperses the metal ions in tap water such as calcium, magnesium, etc., without precipita- tion; both additives combine effectively to emulsify organic residues, oils and greases,. lUlllllllllllllllllllllllllK 3298. etc., and disperse finely divided deposits such as activated charcoal, organic or inorganic pigments, and various catalysts used in organic synthesis. Packed in convenient rectangular canisters containing 3 Ibs., and in 25 Ib. and 100 Ib. fiber drums.
