Products

Kollidon® VA 64 is a white or slightly yellowish, free-flowing powder with a faint characteristic odor and practically no taste. It readily dissolves in all hydrophilic solvents. Solutions of more than 10 % concentration can be prepared in water, ethanol, isopropanol, methylene chloride, glycerol and propylene glycol. It is less soluble in ether, cyclic, aliphatic and alicyclic hydrocarbons.

Kollicoat® MAE 100-55 is a white redispersible powder with a faint characteristic odor. The product contains 0.7% sodium lauryl sulfate (USP) and 2.3% Polysorbate 80 (Ph. Eur.) as emulsifying agents. The fatty acids used in the manufacture of Polysorbate 80 are of vegetable origin. Kollicoat® MAE 100-55 is a weakly acidic copolymer that dissolves at a pH above 5.5. Kollicoat® MAE 100-55 dissolves in methanol and ethanol to yield clear to slightly cloudy solutions. It is also soluble in dilute alkaline solutions.

Kollidon® SR is a mixture of 80% of polyvinyl acetate and 19% povidone (Kollidon® 30) in a physical mixture. Approximately 0.8% of sodium lauryl sulfate and about 0.2% of silica are used as stabilizers. It is supplied as slightly yellowish, free-flowing powder. Kollidon® SR Polymer is insoluble in water and very soluble in N-methylpyrrolidone.

Soluplus® is a polymeric solubilizer with an amphiphilic chemical structure, which was particularly developed for solid solutions. Due to its bifunctional character, it is able to act as a matrix polymer for solid solutions on the one hand, and, on the other hand, it is capable of solubilizing poorly soluble drugs in aqueous media. Furthermore, Soluplus® can increase the bioavailability of poorly soluble drugs.

Kollitab™ DC 87 L is an almost white, odorless, and free-flowing powder. It is a coprocessed excipient based on lactose monohydrate (87%), crospovidone (9%), Kollicoat® IR (3%) and sodium stearyl fumarate (1%).
