ASTM D6940 Stability Testing of Adhesive Cosmetics: Eurolabs Laboratory Testing Service

The stability testing of adhesive cosmetics is a critical aspect of ensuring the safety, efficacy, and quality of these products. ASTM D6940 is a standard test method developed by the American Society for Testing and Materials (ASTM) that evaluates the stability of adhesives used in cosmetic applications.

Relevant Standards

  • ISO 2819:2013 - Adhesives for bonding materials to human skin - Part 1: General requirements

  • ASTM D6940-18 - Standard Test Method for Evaluating the Stability of Adhesive Cosmetics

  • EN 16610-40:2015 - Personal protective equipment against the risk of cuts by hand tools and hand-held chain saws - Requirements for materials and performance level

    • International and National Standards

    ASTM D6940 is a widely recognized standard in the cosmetic industry, with international and national standards referencing its requirements. The standard has been adopted by various countries and industries, ensuring consistency and comparability of test results.

    Standard Development Organizations

    The ASTM Committee on Adhesives (D-28) is responsible for developing and maintaining standards related to adhesives, including ASTM D6940. This committee ensures that the standard remains relevant and up-to-date with industry needs.

    Evolution of Standards

    Standards evolve over time as new technologies and methods emerge. The development process involves ongoing research, testing, and feedback from industry experts and stakeholders.

    Standard Numbers and Scope

  • ASTM D6940-18 - Standard Test Method for Evaluating the Stability of Adhesive Cosmetics

    • Scope: This standard covers the evaluation of the stability of adhesives used in cosmetic applications.

    Parameters tested:

    - pH value

    - Viscosity

    - Solids content

    - Moisture content

    Compliance Requirements

    Manufacturers must comply with relevant standards and regulations to ensure product safety and quality. Non-compliance can result in product recalls, fines, or even business closure.

    Standard Compliance for Different Industries

    Step-by-Step Explanation of the Test

    1. Sample preparation: Adhesive samples are prepared according to ASTM D6940 guidelines.

    2. Testing equipment: The test is conducted using specialized equipment, such as viscometers and pH meters.

    3. Temperature and humidity control: The testing environment is maintained at a controlled temperature (e.g., 23C 2C) and relative humidity (e.g., 50 10).

    Testing Parameters

  • Viscosity

  • pH value

  • Solids content

  • Moisture content

    • Data Analysis and Reporting

    Test results are analyzed and reported according to ASTM D6940 guidelines. Manufacturers must provide detailed documentation, including test protocols, data sheets, and certifications.

    Continuity and Calibration

    The testing process involves calibration and maintenance of equipment to ensure accuracy and reliability. Results are verified through internal quality control checks.

    Quality Control Procedures

  • In-house testing

  • Independent laboratory testing

  • Regular equipment calibration and maintenance

    • Regulatory Compliance

    Manufacturers must comply with relevant regulations, such as those set by the FDA (US), EU Cosmetics Regulation, and ISO 2819.

    Continuity and Certification

    Test results are certified according to ASTM D6940 guidelines. Manufacturers can demonstrate compliance through documentation, certificates of analysis, and periodic audits.
