First Generation

History

MDBS

Second Generation

DMDBS

Third Generation

Mediocre thermal stability &

limited clarity

Improved organoleptics,

but still acetal sorbitol

DBN

Fourth Generation

Improved haze, higher thermal

stability but poor organoleptics

Sugar based technology,

high loading & plate-out

New Chemistry RiKACLEAR PC1

RiKACLEAR® PC1

� Non acetal-sorbitol

� Low haze and excellent stiffness

� No plate-out

� Reliable and compatible clarifier

� Superior and robust long-term clarifier

� Efficient low dosing clarifier

� Food contact applications
