5. HISTORY
DBS Poor thermal stability &
limited clarity
First Generation
MDBS Improved haze, higher thermal
stability but poor organoleptics
Second Generation
DMDBS Improved organoleptics,
but still acetal sorbitol
Third Generation
New Chemistry
DBN Sugar based technology,
RiKACLEAR PC1
high loading & plate-out
Fourth Generation

6. OLD TECHNOLOGY VS. NEW CHEMISTRY
ACETAL-SORBITOLS
Clarity X Sugar based
Tc X Yellowness
Mechanical Properties X Inferior Organoleptics
X Plate Out
OLD TECHNOLOGY
