Simplify Your Test Period Planning With Cosming

The Importance of Proper Test Planning in Cosmetic Product Development and Market Launch

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.
     

    ► Patch Test & Efficacy Testing

    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
