This document discusses sugar coating technology for tablet cores. Sugar coating is a multi-step process that involves coating the tablet core with sucrose syrup and evaporating the solvent to leave a sugar coating. The advantages of sugar coating include using widely accepted raw materials and not requiring complex equipment. The sugar coating process involves sealing the core, applying sub coatings using sucrose solution and calcium carbonate or talc, smoothing layers, coloring, polishing, and printing. Common faults are cracking, splitting, inversion causing stickiness.

2. SUGAR COATING
 Sugar coating is the process of coating
tablet core with sucrose syrup
 consequently evaporating the solvent
of syrup
 with the help of hot air .
 a multi-step process.
 use of labour is more, require a
fair degree of skill.

3. ADVANTAGES OF S.C
 Constituent raw materials are
widely accepted
 No regulatory problems.
 No complex equipment or services
are required.
 For high humidity climates

4. STEPS OF SUGAR COATING

5. STAGES IN SUGAR COATING
 Sugar coating is a multi step process.
1. SEALING core-
application of a water impermeable
polymer
-Shellac
-cellulose acetate phthalate
- polyvinyl acetate phthalate
2 SUB COATING
The actual sugar coating which
leads to 50-100% increase in weight.
By adding:
-calcium carbonate or talc in
combination with sucrose solution.

3. SMOOTHING
Remove rough layers formed in step 2
with the application of sucrose syrup.
4. COLORING
-Consists of multi-step application of
syrup containing the required
color(dye/pigment).
-for aesthetic purposes often titanium based
pigments are included.

5. POLISHING
effectively polished to give characteristic shine,
commonly using beeswax, carnauba wax
6. Printing –
indelible ink for characterisation.

8. SUGAR COATING FAULTS
 A common fault is cracking and
splitting of the sugar coat.
 Inversion and stickiness are caused
by the presence of inverted sugar .
 Are unfortunately brittle and are
prone to chipping if subjected to an
inappropriate mechanical stress.
