Kollicoat Smartseal 30 D

Kollicoat® Smartseal 30 D is the first water based polymer dispersion for taste masking and moisture barrier applications. It was developed to simplify and accelerate aqueous film coating operations and opens new doors for formulating tablet, pellet and particle coatings.Bitter and moisture-sensitive active ingredients can pose quite a challenge to formulators – but not anymore. Either of the two desired effects, concealing unpleasant tastes and creating a moisture barrier, can be achieved with one functional film-forming polymer.

Kollicoat® Smartseal 30 D is highly impermeable to water vapor, helping preserve the potency of sensitive active ingredients. What’s more, the polymer is highly stable in saliva and specifically soluble in gastric juice. This ensures effective protection from unpleasant tastes in the patient’s mouth and rapid release and onset of action of active ingredients in the stomach. An aqueous polymer dispersion, Kollicoat® Smartseal 30 D is easy to handle, and convenient to apply. And since it can be used in highly concentrated coating suspensions and at high spray rates, you benefit from reduced process times – and significant cost savings.

Molecular Weight The weight average molecular weight determined with size exclusion chromatography (SEC) – light scattering is approx. 200 000 dalton.
Chemical Nature Kollicoat® Smartseal 30 D is an aqueous dispersion of a co-polymer comprising methyl methacrylate (MMA) and diethyla- minoethyl methacrylate (DEAEMA). It also contains macrogol cetostearylether and sodium lauryl sulfate as stabilizers.
Chemical name: Methyl methacrylate and diethylaminoethyl methacrylate copolymer dispersion
Physical Form 30% Dispersion
Description Kollicoat® Smartseal 30 D is an aqueaous polymer dispersion with a solids con- centration of approx. 30%. It contains methyl methacrylate and diethylaminoethyl methacrylate copolymer stabilized with approx. 0.6% macrogol cetostearyl ether and 0.8% sodium lauryl sulfate. It comes as a milky white to yellowish liquid with a faint characteristic odor.
