Analytical & Product Testing

Dedicated to Product Performance, Quality, and Compliance

Analytical testing is the backbone of the successful development of topical and non-sterile liquid products. From early method development through commercial release, every decision relies on the accuracy and reliability of the analytical data generated.

CPL provides a fully integrated suite of analytical development services, microbiological testing, method validation, and GMP-compliant raw material and product testing, designed explicitly for semi-solids, such as creams, ointments, gels, and lotions, as well as liquids, including nasal sprays, solutions, and suspensions. Our in-house capabilities eliminate the delays, inconsistencies, and re-testing cycles that often occur with external labs, accelerating development and strengthening your regulatory confidence.

CPL's Solution

Increasing Complexity, Higher Standards, and Zero Room for Error

Industry Challenge

Complex rheology and microstructure require precise analytical control.

Specialized analytical expertise for semi-solids & liquids.

CPL uses purpose-built methods and equipment designed specifically for rheology, microstructure, viscosity, and particle-size characterization in topical and liquid products.

Industry Challenge

Semi-solid characterization requires tools and expertise not common in traditional labs.

Dedicated semi-solid and topical product testing capabilities.

CPL’s analytical team develops and executes methods tailored to ointments, creams, gels, lotions, and other complex matrices.

Industry Challenge

Non-sterile liquid formulations require robust performance testing and container-closure verification.

Comprehensive analytical coverage for liquids and sprays.

CPL performs dose uniformity, pump performance, spray testing, stability, microbial assessments, and full container-closure system evaluation.

Industry Challenge

Regulators expect rigorous method validation, USP compliance, and thorough documentation.

ICH- and USP-aligned analytical method development & validation.

CPL delivers validated methods, comprehensive documentation packages, and stability-indicating profiles that support clinical manufacturing and commercial scale-up.

Industry Challenge

Critical Quality Attributes must remain consistent from bench through commercial GMP manufacturing.

Analytical methods built for manufacturability and lifecycle control.

Methods are developed with scalability, repeatability, and long-term GMP execution in mind, reducing variability across the full product lifecycle.

Industry Challenge

Fragmented analytical services increase the risk of downstream failures.

Unified, in-house analytical and testing ecosystem.

CPL eliminates external variability with a fully integrated system that encompasses method development, method validation, release testing, stability, IVRT/IVPT, and QC, all under one roof and with shared expertise.
