Every formulation undergoes rigorous, multi-stage testing in our certified laboratories to guarantee purity, stability, performance, and regulatory compliance.
Core Testing Pillars
The Multi-Point Testing Framework
GC-MS Analysis: Gas Chromatography–Mass Spectrometry (GC-MS) is used to verify the purity and authenticity of incoming raw materials (essential oils, fragrance components) against industry standards and our internal benchmarks.
Identity Check: Confirms the chemical fingerprint of the material matches the required composition, protecting against adulteration.
Heavy Metal/Residue Screening: Targeted testing for contaminants in natural extracts.
Accelerated Shelf-Life: Samples are placed in stability chambers under extreme conditions (high heat, cold, and UV light) to simulate aging and predict the product’s performance and shelf life over 12–36 months.
Packaging Compatibility: Testing the finished fragrance oil against the final chosen packaging components (glass, plastic, metal pumps) to ensure no leakage, cracking, or material degradation occurs.
Color & Clarity: Monitoring for changes in product color, clarity, and consistency over the testing period.
Olfactory Evaluation: Trained perfumers and technicians perform blind sensory evaluations to ensure batch-to-batch consistency and fidelity to the final approved scent standard.
Functional Testing: For products like sprays and diffusers, testing includes pump spray patterns, dosage accuracy, and reed throw performance.
Microbial Challenge Testing (Optional): Testing the product’s ability to resist microbial growth, ensuring safety and integrity over its expected use life.
Compliance & Documentation Support
Documentation: All test results are compiled into a comprehensive Technical File/Product Information File (PIF).
Key Outputs: We provide the Certificate of Analysis (COA), Stability Reports, and Safety Data Sheets (SDS) necessary for your regulatory submissions in the EU (CPNP) and the US (FDA/MoCRA).

F.A.Q.
In-House Testing Protocols FAQ Article
A: Our primary purpose is Risk Mitigation and Quality Assurance. Testing guarantees two things for our B2B clients:
Safety & Compliance: We confirm the product is safe for consumer use and meets all relevant regulatory requirements (IFRA, REACH, FDA).
Stability & Performance: We ensure the product will maintain its scent, color, and functional integrity throughout its promised shelf life, protecting your brand’s reputation.
A: Accelerated shelf-life testing is used to predict how long a product will last without physical or chemical changes. Samples are placed in controlled Stability Chambers and exposed to extreme conditions:
High Heat: (e.g., $45^\circ \text{C}$) to simulate warehousing in hot climates.
Cold Cycle: (e.g., $4^\circ \text{C}$) to test resistance to temperature drops.
UV Light: To test color fading.
We compare these samples to a control sample to determine an accurate expiration date (typically 24–36 months).
A: The Gas Chromatography–Mass Spectrometry (GC-MS) machine separates the chemical components of a fragrance oil and identifies them based on their mass. This allows us to:
Verify Identity: Confirm the supplier’s Certificate of Analysis (COA).
Detect Adulteration: Identify any unexpected, cheap fillers or residual solvents that could compromise safety or performance.
A: Fragrance oils contain complex solvents and alcohol that can aggressively interact with plastic, rubber, or certain metal components. Incompatibility can lead to:
Product Failure: Pumps seizing up or dissolving plastic internal parts.
Leakage: Oils degrading the seal of the bottle neck.
Aesthetics: Plastic containers clouding or cracking. We test the finished formula with the final packaging components over time to prevent these costly failures.
A: Yes. We manage the entire in-house QC process, but if your product requires specialized testing (e.g., dermatological testing, specific biodegradability testing, or official clinical claim substantiation), we will coordinate and facilitate that testing with certified, trusted third-party laboratories. This testing is typically billed separately.
A: Yes. Our testing framework is designed specifically to generate the data required by major global regulatory bodies:
EU CPNP: Our stability, allergen, and safety data directly feeds into the mandatory Product Information File (PIF) required for the European Union.
US FDA/MoCRA: Our purity and safety screening confirms the absence of prohibited substances and ensures all ingredients are vetted for safety, aligning with the new U.S. cosmetics regulations.
