EUDRAGIT® RS 30 D

Description

A functional sustained/extended release polymer for customized release profiles, used in combination with EUDRAGIT® RL

Aqueous dispersion

EUDRAGIT RS 30 D is a copolymer of ethyl acrylate, methyl methacrylate and a low content of methacrylic acid ester with quaternary ammonium groups. The ammonium groups are present as salts and make the polymers permeable.

Physical properties: It is a milky-white liquid of low viscosity with a faint characteristic odour.

Characteristics:

• Customized release profile by combination of RL and RS grades in different ratios
• Suitable for matrix structures

Chemical/ IUPAC name: Poly(ethyl acrylate-co-methyl methacrylate-co-trimethylammonioethyl methacrylate chloride) 1:2:0.1

INCI name: Acrylates / Ammonium Methacrylate Copolymer
