LITERATURE
INDUIIN INDULIN (pine wood lignin) stabilizes emulsions by sequestering Ca and Mg Ions which would otherwise precipitate emulsifiers. Foams are stabilized by INDULIN's action in decreasing the in terfacial tension between air and liquid or solid medium. INDULIN is now used in asphalt emul sions and oil well drilling muds, firefighting foams and air entrainment for cement. Where can our technical ad visers put INDULIN to work for you? Send for Bulletins 101 and 1 0 8 .
