Description
VIVAPUR® MCG is a synergistic, co-processed composite consisting of microcrystalline cellulose (MCC) and sodium carboxymethylcellulose (Na-CMC). It is a unique suspending and emulsifying agent, which facilitates a wide range of liquid dosage forms. Due to its extraordinary stabilizing mechanism, VIVAPUR® MCG can be used with a broad variety of active pharmaceutical ingredients (APIs), offering the opportunity for new applications and line extensions for existing products.
VIVAPUR® MCG is a free flowing powder. After activation, MCG builds an opaque-white dispersion which masks insoluble particles, giving the suspension a homogenous appearance. The dispersed VIVAPUR® MCG is distinguished by an odorless and tasteless, smooth but not slimy mouth feel, and handles flavors well. Upon agitation, MCG dispersions show a time-dependent decrease in viscosity and become liquid. A complete, also time-dependent, regeneration of the viscosity takes place during a subsequent rest period. This thixotropic behavior allows:
- Outstanding sprayability of nasal sprays
- Effortless dosing through drenches and dispensers
- Accurate dosage of oral suspensions
- Hassle-free handling of activated gel
- Ideal pumpability
- Smooth and pleasant swallowing without problems
- Excellent content uniformity
VIVAPUR® MCG is used as a suspending agent, emulsifier, and thickener for:
- Oral suspensions
- Veterinary drenches
- Nasal sprays
- Reconstitutable powders
- Gels, creams, and lotions
Benefits:
- Easy handling of dry powder
- Heat stability
- Compatibility with a wide range of ingredients
- Stable over a wide pH range
- Safe for us in animal health products, pediatric suspensions, and nutraceuticals
