FprEN ISO 11609 - Dentistry – Dentifrices: Requirements and Test Methods

Dentistry - Dentifrices - Requirements, test methods and marking (ISO/FDIS 11609:2025)

What It Covers:
FprEN ISO 11609 defines physical and chemical property requirements, test protocols, and packaging/marking guidelines for dentifrices, notably toothpaste products. This standard is pivotal for companies manufacturing oral hygiene products intended for daily consumer use with a toothbrush.

Key Requirements and Specifications:

• Total fluoride content limits to prevent overexposure
• Restriction on heavy metals (max 20 mg/kg) for user safety
• Required pH range (below 10.5) to protect oral tissues
• Limitation on dentifrice abrasivity—ensuring safety for enamel and dentine
• Exclusion of readily fermentable carbohydrates to support oral health
• Test methods for pH, abrasivity, stability, and microbiological contamination
• Detailed marking and labelling: ingredient list (INCI), batch tracking, expiry, safety warnings
• Packaging standards to minimize contamination and maintain integrity over shelf life

Who Should Comply:

• Oral care product manufacturers
• Brand owners and private labelers
• Regulatory affairs and quality management
• Dental product procurement for clinics and retailers

Practical Implications: Meeting FprEN ISO 11609 helps manufacturers achieve regulatory approval, build market trust, and minimize product recalls related to composition or labeling. Dental professionals and distributors rely on compliance to guarantee predictable, safe performance.

Notable Changes (from previous iterations):

• Updated and more stringent fluoride control
• Expanded test protocols (e.g., for abrasivity using ADA-validated methods)
• Harmonized packaging and marking for global market access

Key highlights:

• Aligns with global dental health guidelines
• Supports product claims for safety and efficacy
• Reduces liability risk for manufacturers and suppliers
