Cellactose® 80
Premium co-processed Excipient
75 % alpha-lactose monohydrate and 25 % powdered cellulose.
Co-processed excipients (CPEs) play a key role in modern pharmaceutical manufacturing by offering significantly improved functionality compared to conventional excipients. Through the physical combination of established substances – multifunctional particle systems are created with enhanced flowability, compactibility, and reduced sensitivity to lubricants. This leads to improved tablet uniformity and mechanical strength while reducing the need for additional formulation steps. Especially in direct compression, CPEs enable more efficient and robust tablet production, even with high drug loads or poorly compressible APIs. Since they are composed of pharmacopoeial-approved components, regulatory requirements are minimal, further increasing their appeal.
Cellactose® 80 is a co-processed excipient of 75 % alpha-lactose monohydrate and 25 % powdered cellulose, designed for direct compression. It offers excellent flowability, compactibility, and high adherence capacity, ensuring uniform content in low-dose formulations and enhanced tablet hardness in high-dose applications.
Benefits
- Excellent compactibility and flowability
- Perfectly suited for poorly compressible APIs (e. g. herbal extracts)
- High adherence capacity to API
- Ideal tablet surface for easy and economical coating
- High adherence capacity may prevent segregation and improves content uniformity
