Overview

EN ISO 10873:2026 sets out standardized requirements for denture adhesives used by wearers of removable dentures. Developed by CEN and ISO Technical Committee 106/SC 7 (Dentistry), this international standard provides a comprehensive framework for the classification, testing, and labeling of denture adhesives meant for direct consumer use. The standard excludes dental lining materials prescribed or applied by dental professionals. By harmonizing product requirements and test methods, EN ISO 10873:2026 aims to improve user safety, product effectiveness, and market consistency for denture adhesive products.

Key Topics

• Classification of Denture Adhesives
  The standard distinguishes denture adhesives into two types for consumer use:

  • Type 1: Glue type
    • Class 1: Powder form
    • Class 2: Cream form
    • Class 3: Sheet or tape form
  • Type 2: Liner type (non-aqueous, typically sheet material)

• Fundamental Requirements

  • Biocompatibility: Assess the effects of released substances on users.
  • Microbiological Safety: Products must undergo appropriate microbiological testing to ensure safety.
  • Stability: Denture adhesives must maintain their properties after stipulated aging procedures and not deteriorate under normal storage.

• Performance Criteria

  • For Type 1 adhesives: Washability and minimum adhesion strength (not less than 5 kPa).
  • For Type 2 adhesives: Minimum adhesion strength, effective peeling property (no residue after removal), and specified consistency.

• Test Methods and Sampling
  Standardized procedures define testing conditions, apparatus, and criteria for evaluation. Multiple tests are conducted to assess washability, adhesion, peeling, and consistency following detailed protocols.

• Packaging and Labelling
  Packaging must protect the product against contamination. Labels and instructions must include application, removal, ingredient listing, and safety cautions.

Applications

EN ISO 10873:2026 is essential for:

• Manufacturers of denture adhesives

  • Guarantees that denture adhesive products conform to recognized international safety and quality standards.
  • Provides a clear basis for product development, testing, and claims substantiation.

• Regulatory Authorities

  • Facilitates market surveillance and regulatory approvals by standardizing requirements for denture adhesives.
  • Supports harmonization of consumer health and safety regulations across regions.

• Retailers and Distributors

  • Enhances confidence in product claims and labeling.
  • Reduces liability by ensuring only compliant products are supplied to the market.

• Consumers

  • Ensures safer and more effective denture adhesives are available.
  • Provides transparency through standardized labeling, usage instructions, and cautionary advice.

Related Standards

EN ISO 10873:2026 references critical standards that support its implementation:

• ISO 1942: Dentistry - Vocabulary: Defines key terms and concepts within the dental field.
• ISO 3696: Water for analytical laboratory use - Specification and test methods: Ensures water quality used in testing adhesives.
• ISO 7823-2: Plastics - Poly(methyl methacrylate) sheets - Extruded sheets: Specifies material standards for test samples.
• ISO 10993-1, ISO 7405: Guidance on biocompatibility for dental materials.

By following EN ISO 10873:2026, stakeholders can ensure denture adhesive products meet internationally recognized criteria for safety, efficacy, and consumer use, supporting both regulatory compliance and market confidence.

Introduction
Denture adhesives are used for the improvement in retention stability of removable denture to soft
supporting tissues temporarily. This document is intended to determine the physical and chemical
properties of denture adhesives.
Specific qualitative and quantitative requirements for freedom from biological hazards are not included
in this document. It is recommended that, in assessing possible biological hazards, reference be made to
ISO 7405 and ISO 10993-1.
