Proper planning of testing procedures during cosmetic product development and market launch is critical for both time management and regulatory compliance.
At Cosming, we aim to support your product development process by sharing the average turnaround times for our laboratory analysis services. The durations listed below reflect standard timelines under laboratory conditions for each type of test.
► Microbiological Analysis
Duration: 5–7 business days
Microbiological safety is essential for protecting consumer health. Our core tests include:
Total Aerobic Microbial Count (TAMC)
Yeast and Mold Count (TYMC)
Detection of Pathogenic Microorganisms:
Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Candida albicans
► Water Microbiology Analysis
Duration: 3–5 business days
Microbiological quality control of water used in manufacturing, laboratory processes, and raw materials is conducted in accordance with legal regulations.
Our water microbiology tests include:
Total Colony Count (at 22 °C and 37 °C)
Escherichia coli Count
Coliform Bacteria Count
Fecal Enterococcus Count
► Physicochemical Analysis
Duration: 1–3 business days
Basic tests for formulation validation and quality control:
pH measurement
Viscosity
Density
Preliminary stability tests
► Claim Substantiation Tests
Duration: 7–10 business days
Scientific verification of marketing claims is crucial for labeling and promotion. Common examples include:
“Alcohol-Free”
“Gluten-Free”
“Vegan”
“Non-GMO”
► Chemical Composition Analysis
Duration: 3–5 business days
Evaluation of a product’s chemical stability and content accuracy:
Total acidity/alkalinity
Free alkalinity
Ingredient-specific assessments
► Active Ingredient Analysis (GC-MS, HPLC, UV-VIS)
Duration: 10–15 business days
Quantitative analysis of botanical extracts, vitamins, preservatives, and other actives using advanced instrumentation:
Plant extracts
Vitamins A, C, E, etc.
Phenolic compounds
Alcohol, parabens, and derivatives
► Antimicrobial Activity Test
Duration: 7–10 days
This test evaluates the product’s effectiveness against target microorganisms. Depending on the method, the following are measured:
Disk Diffusion Method:
Qualitative assessment based on inhibition zone diameters formed on microbial cultures.
Minimum Inhibitory Concentration (MIC):
Quantitative analysis of the lowest concentration that inhibits microbial growth.
These tests are especially relevant for preservatives, natural antimicrobial ingredients, and product safety claims.
Duration: Approximately 30 days
Dermatological safety and product efficacy are assessed through:
Dermatological compatibility studies
Practical efficacy testing with consumer panels or expert evaluations
► Stability & Shelf-Life Testing
Tests are conducted under controlled conditions with varying temperature, humidity, and light levels to evaluate product stability.
Accelerated Stability Testing: 12 weeks
Real-Time Stability Testing: Based on target shelf-life (e.g., 6–12 months)
► Challenge Test (Preservative Efficacy Test)
Duration: Approximately 40 days
This test assesses the effectiveness of preservatives against microbial contamination.
5-day preparation period
Sampling on days 0, 7, 14, and 28
Final 5-day incubation and result reporting
