Cinoll’s Quality Control system follows GMP and ISO standards. We strictly control all product’s quality to provide safe manufacturing.
Quality System
ISO 22716 GMP-Certified Quality Management
At Cinoll, quality is not a department — it is embedded in every stage of our operation. Our factory operates under ISO 22716 Good Manufacturing Practice (GMP) certification, the internationally recognised standard for cosmetics manufacturing. Every process, from raw material intake to finished product release, is governed by a comprehensive set of Standard Operating Procedures covering 30 documented quality management programmes.
Our quality management system ensures full traceability for every batch, structured change control, rigorous deviation handling, and a continuous improvement cycle through internal audits and corrective and preventive action protocols.
- Document and Record Control — All production records, test results, and batch documentation are systematically maintained and traceable
- Batch Traceability — Every production batch is assigned a unique identifier, enabling full forward and backward traceability
- Change Management — Formulation, process, and supplier changes follow a structured review and approval workflow
- Deviation and CAPA — Non-conformances are investigated, root causes identified, and corrective actions implemented and verified
- Internal Audit Programme — Regular internal audits ensure ongoing compliance with GMP requirements
- Supplier Qualification — All raw material and packaging suppliers are evaluated and approved before use

Formula Development Testing
Testing During Formula Development
Before any formula is approved for production, it undergoes a rigorous testing programme in our in-house laboratory. Using toothpaste as an example, every new formulation must pass the following core tests before it is released for client sampling or mass production.
Stability Testing
Accelerated (40°C / 75% RH) and real-time stability studies to confirm the formula remains physically and chemically stable throughout its intended shelf life.
Preservative Challenge Test
Challenge testing to verify that the preservative system effectively inhibits microbial growth under simulated use conditions, in compliance with ISO 11930.
Microbial Testing
Total aerobic microbial count, total yeast and mould count, and absence testing for specified pathogens including Staphylococcus aureus and Pseudomonas aeruginosa.
Heavy Metal Testing
Analysis for lead, arsenic, mercury, and cadmium to ensure compliance with international cosmetics safety limits across all major markets.
pH Testing
Precise pH measurement to confirm the formula falls within the target range for safety, efficacy, and compatibility with packaging materials.
Viscosity Testing
Rotational viscometry to verify texture and flow consistency, ensuring the product performs correctly during filling and meets consumer expectations.
Mass Production Documentation
Complete Documentation for Every Production Batch
After every mass production run, Cinoll provides a full set of quality and safety documentation. These documents give your regulatory team, responsible person, and customers confidence in the safety, consistency, and traceability of every batch we produce.
Certificate of Analysis (COA)
Batch-specific test results confirming the finished product meets all agreed specifications, including appearance, pH, viscosity, and microbial limits.
Material Safety Data Sheet (MSDS)
Comprehensive safety information covering ingredient hazards, handling precautions, storage requirements, and emergency response guidance.
Stability Testing Report
Accelerated and real-time stability data demonstrating the product's physical and chemical integrity throughout its declared shelf life.
Preservative Challenge Test Report
Evidence that the preservative system meets ISO 11930 criteria, confirming the product is protected against microbial contamination during use.
Microbial Testing Report
Total aerobic count, yeast and mould count, and pathogen absence results for the finished batch, tested in our in-house laboratory.
Heavy Metal Testing Report
Analytical results for lead, arsenic, mercury, and cadmium, confirming compliance with the limits set by the EU, US, and other major regulatory frameworks.
In-House Laboratory
Our In-House Testing Laboratory
Cinoll operates a fully equipped in-house laboratory within the factory, staffed by a team of experienced chemists and quality specialists. Having testing capabilities on-site means we can respond quickly to client requests, conduct routine quality checks without delay, and provide fast turnaround on sample testing during the development phase.
Our laboratory team brings deep expertise in cosmetics chemistry and applies meticulous attention to detail at every stage of testing. Whether you need a quick pH check on a new sample or a full stability programme for a new product launch, our team is ready to support you.
- Rapid in-process quality checks during production
- Sample testing for clients at any stage of development
- Stability programme management from formulation to launch
- Microbiology testing in a dedicated clean environment
- Instrument calibration and maintenance records kept in compliance with ISO 22716
- All test data archived and traceable to batch records

Third-Party Testing
Independent Third-Party Testing for Complete Assurance
In addition to our comprehensive in-house testing programme, Cinoll works with accredited independent laboratories to conduct third-party testing on our oral care formulations. This provides an additional, unbiased layer of verification that gives our clients and their regulatory teams complete confidence in the safety and performance of every product we manufacture.
RDA Testing (ISO 11609)
Relative Dentin Abrasivity testing conducted by independent labs to confirm toothpaste formulations are gentle on enamel and safe for daily use. Results are benchmarked against international safety limits.
Enamel Abrasivity Testing
Complementary to RDA, enamel abrasivity testing evaluates the effect of abrasive ingredients on enamel surfaces, ensuring whitening and cleaning formulations remain within safe parameters.
Fluoride Content and Stability
Independent quantification of total and soluble fluoride content, along with fluoride ion loss stability testing, to verify that fluoride-containing products deliver consistent efficacy throughout shelf life.
Whitening Efficacy Testing
In vitro colour stability and stain-removal studies using spectrophotometry to objectively measure the whitening performance of toothpaste formulations against standardised benchmarks.
Sensitivity Relief Testing
Dentinal tubule occlusion testing to evaluate the effectiveness of sensitivity-relief ingredients in blocking exposed tubules and reducing sensitivity, supporting product claims.
Heavy Metal and Contaminant Screening
Third-party elemental analysis for lead, arsenic, mercury, cadmium, and other regulated contaminants, providing independent confirmation of compliance with EU, US FDA, and international limits.
