First Generation

HISTORY

MDBS

Second Generation

DMDBS

Third Generation

Poor 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

OLD TECHNOLOGY VS. NEW CHEMISTRY

ACETAL-SORBITOLS

OLD TECHNOLOGY

� Clarity

� Tc

� Mechanical Properties

X Sugar based

X Yellowness

X Plate Out
