VIVAPUR® MCG 811 P

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
