Raw Material Analysis

Active ingredients, inactive ingredients and processing aids all fall under the general category of Raw Materials.  The assurance of product quality begins with the concept of Supply Chain Quality Management.  This includes qualification of raw material vendors, validation of the test results that vendors report on their raw material Certificates of Analysis, and a program of ongoing quality testing, monitoring the identity, strength, quality and purity of raw materials.  Supply Chain Quality Management ensures a more efficient use of production resources and can eliminate batch rejections due to poor raw material quality. Manufacturers of pharmaceutical and other therapeutic products are required to monitor the quality of the raw materials that are used in their products. Though not currently required of manufacturers of cosmetic and personal care products, many understand that monitoring the quality of raw materials used in their products makes good business sense and as a result, conduct raw material testing with the hope of reducing production delays, downtime, batch reworking, rejections and missed shipping dates.

CPT is a qualified and experienced testing lab that ensures raw material analyses are conducted in strict accordance with compendial, client or in-house methodologies, and in full compliance with all applicable regulations.   Additionally, CPT is ISO/IEC 17025:2005 accredited, with many of the most common raw material tests included within our Scope of Accreditation.

Which Raw Materials Does CPT Test?

CPT has a long history of conducting testing on raw materials of all types, including but not limited to pharmaceutical and dietary supplement active ingredients, preservatives, botanical ingredients, inactive ingredients, processing aids, solvents, polymeric resins and more.  CPT always recommends to its clients that wherever possible, official compendial methods be employed in the testing of raw materials.  Where this is not possible, validated methods or those published in peer-reviewed literature are a suitable alternative.

Our Raw Materials Testing Capabilities

CPT maintains state-of-the-art Analytical, Microbiological, Clinical, Photobiology, and In-Vitro Toxicology testing laboratories, all of which are at your disposal in the determining of the quality and safety of the raw materials you utilize in your products.

Using our specialized departments and well-respected lab facility, we have the capability of testing a wide range of raw materials with respect to their physical, chemical, and microbiological attributes, and whether or not they may promote irritation, or exhibit characteristics for allergenicity, photo-toxicity or photo-allergenicity.  Our in-house experts are ever ready to offer guidance and to address any questions or concerns you may have regarding the testing of your raw materials.

Testing Techniques Employed by CPT

Physical Testing – Examples of which are Specific Gravity, Flash Point, Particle Size, Refractive Index and Optical Rotation.

Wet Chemistry Testing – Examples of which are titrations, and extraction and/or reaction processes leading to spectroscopic or gravimetric analysis.

Instrumental Analysis – Analysis employing modern instrumentation such as HPLC, UPLC, GC, UV/Vis Spectrophotometry, ICP-MS, AA/Graphite Furnace, FTIR, and DSC.

Classical Microbiological Testing – Examples of which include Microbial Content using USP <61> and <62> and other standards, LAL Endotoxin, Ames Mutagenicity and Sterility.

Human Repeat Insult Patch Testing (HRIPT) –  Examples of which include Topical Irritation, Allergenicity, Phototoxicity and Photoallergy testing.

In Vitro Toxicology Testing – Non-animal testing employing US and international methodologies for determining irritation and other undesirable potentials.

Commonly Requested USP Raw Material Tests

Residual Solvents <467>
This testing is conducted to confirm that if present, residual solvents do not exceed acceptable levels in raw materials.

Elemental Impurities <233>
This testing is conducted to confirm that if present, elemental impurities do not exceed acceptable levels in raw materials.

Assays and Related Compounds/Impurities (Monograph-specific)

This testing is conducted to confirm that active ingredient and preservative raw materials are of the proper strength/potency, and that related compounds /impurities do not exceed acceptable levels.

Our Departments

Based on the individual needs of our clients, we offer a wide range of support across various departments. Since initial product testing can be fairly complex in terms of a high-quality, safe and trusted product, our clients typically explore the benefits of numerous departments and areas of expertise, including:

  • Clinical —Efficacy trials can be performed for safety, consumer in-use, and to support claims, such as ‘dermatologist-tested’ and ‘ophthalmologist-tested.’
  • In-Vitro Safety — Our in-vitro safety department assists clients when they are looking to perform non-animal or animal-free toxicology testing.
  • Microbiology — Microbial contamination and preservative testing is key to cosmetic products.
  • Photobiology —From SPF and Water Resistant claims to PhotoAllergy and Phototoxicity studies, CPT is the world leader in sunscreen testing.
  • Analytical — From raw materials, batch release, and stability shelf-life testing to “free-of” and low-level detection claims, our analytical department ensures that all requirements are met based on industry standards.
