General Description:
1-Hydroxyethylidene-1,1-diphosphonic acid (HEDP) is an organic phosphonic acid that acts as a chelating agent. In its 50% solution form, it appears as a clear, colorless to pale yellow liquid. HEDP is known for its ability to bind to metal ions, preventing the formation of insoluble metal salts. This property makes it valuable in various industrial and cosmetic applications.
Uses in the Cosmetic Industry:
- Chelating Agent: HEDP is used in cosmetic formulations to bind and sequester metal ions, which can improve the stability and efficacy of the product. It helps to prevent the degradation of active ingredients and maintain the product's appearance and performance.
- Water Softening: In personal care products such as shampoos and conditioners, HEDP can act as a water softener, enhancing the cleansing properties of the formulations by preventing the formation of insoluble salts that can reduce lather and leave residues on hair and skin.
- pH Stabilizer: HEDP can help to stabilize the pH of cosmetic products, ensuring they remain within a desirable pH range throughout their shelf life.
- Preservative Booster: By binding to metal ions that could otherwise catalyze the degradation of preservatives, HEDP can enhance the effectiveness and longevity of preservative systems in cosmetic formulations.
Hazards and Safety Concerns
While HEDP is effective in its applications, there are certain safety and health concerns associated with its use:
- Skin and Eye Irritation: HEDP can cause irritation to the skin and eyes upon contact. It is essential to use products containing HEDP according to instructions and to avoid direct contact with concentrated forms of the chemical.
- Inhalation Risk: Inhalation of HEDP in aerosol form can cause respiratory tract irritation. Proper ventilation and protective equipment should be used when handling concentrated HEDP solutions.
- Environmental Impact: HEDP is persistent in the environment and can contribute to water pollution. It is crucial to ensure proper disposal and treatment of wastewater containing HEDP to minimize its environmental impact.
- Toxicity: While generally considered safe in the concentrations used in cosmetic products, high doses of HEDP can be toxic if ingested. Products containing HEDP should be kept out of reach of children and clearly labeled to avoid accidental ingestion.

THE STORY OF HEDP 50%
HEDP 50%: The High-Performance Chelating Agent for Formula Stabilitya
HEDP (1-Hydroxyethylidene-1,1-Diphosphonic Acid) is a powerful chelating and scale-control agent used to stabilize cosmetic, personal-care, and home-care formulations.
It prevents metal ion contamination, discoloration, oxidation, and ingredient degradation, making it essential for surfactant-heavy, high-mineral, or long-shelf-life products.
A Diphosphonic Acid Designed for Superior Metal Binding & Stability
HEDP is a diphosphonic acid derivative, synthesized for high chelation strength.
Its molecular structure allows it to:
• Bind iron, calcium, magnesium, copper & heavy metals
• Prevent scale formation in water-based systems
• Protect sensitive ingredients from oxidation
• Maintain clarity and color even in hard-water environments
TRCkem provides 50% active aqueous solution, ideal for both cosmetics and personal-care applications.
Stabilize. Protect. Preserve.
HEDP 50% offers multiple formulation advantages:
✅ Prevents metal-induced oxidation (keeps color & fragrance stable)
✅ Enhances preservative effectiveness
✅ Controls scale formation in water-based products
✅ Improves foam performance in shampoos & cleansers
✅ Maintains stability in high-mineral or hard-water regions
Used in: shampoos, face washes, body washes, serums, cleansers, liquid detergents, and bath products.
High-Efficiency Chelator — Use at Low Levels for Maximum Performance
• Typical use level: 0.05–0.5% (up to 1% in heavy-duty systems)
• Add to water phase during the early mixing stage
• Works effectively across wide pH range (2–12)
• Compatible with surfactants, preservatives, fragrances & active ingredients
• Avoid direct skin contact in raw form—use gloves and protective handling
• Store tightly sealed, away from heat and moisture
• Biodegradable and globally approved for personal-care applications
