Application of ATMP•Na4 in daily chemicals

ATMP·Na₄ is a highly effective chelating agent, scale inhibitor, and stabilizer widely used in daily chemical products due to its excellent metal ion sequestration, anti-scaling, and compatibility properties. Below are its key applications and benefits:

1. Main Applications in Daily Chemicals(1) Detergents & Cleaning ProductsRole:

• Water Softening: Strongly chelates Ca²⁺, Mg²⁺, Fe³⁺ in hard water, preventing soap scum (calcium stearate) and improving cleaning efficiency.

• Anti-redeposition: Helps keep dirt and stains suspended in water, preventing re-deposition on fabrics or surfaces.

• Phosphate Substitute: Used in low-phosphate or phosphate-free detergents to comply with environmental regulations.

Products:

• Laundry detergents (powder/liquid)

• Dishwashing liquids

• Household cleaners (floor, bathroom, kitchen)

Dosage:

• 0.5%–5% (by weight), adjusted based on water hardness.

(2) Personal Care & CosmeticsRole:

• Stabilizer: Prevents metal ions (Fe³⁺, Cu²⁺) from catalyzing oxidation in shampoos, creams, and lotions.

• Preservative Booster: Enhances the effectiveness of preservatives like parabens.

• pH Buffer: Maintains product stability in alkaline formulations (e.g., hair relaxers).

Products:

• Shampoos & conditioners

• Liquid soaps & shower gels

• Toothpaste (stabilizes peroxide in whitening formulas)

Dosage:

• 0.1%–2% (typically used at low concentrations).

(3) Industrial & Institutional (I&I) CleanersRole:

• Descaling Agent: Removes limescale in dishwasher detergents and industrial cleaners.

• Corrosion Inhibitor: Protects metal surfaces (e.g., in machine dishwashing).

Products:

• Automatic dishwasher detergents

• CIP (Clean-in-Place) cleaners for food processing

• Metal surface treatment solutions

Dosage:

• 1%–10%, depending on scaling potential.

2. Advantages Over Alternatives

3. Recommended Formulations(A) Laundry Detergent (Liquid)

• ATMP·Na₄: 2%

• LAS (Surfactant): 15%

• Nonionic surfactant: 5%

• Sodium citrate: 3%

• Enzymes & Fragrance: q.s.

(B) Descaling Cleaner

• ATMP·Na₄: 8%

• Citric acid: 10%

• Nonionic surfactant: 2%

• Water: Balance

4. Key Considerations

• pH Range: Works best at pH 6–11 (stable in alkaline conditions).

• Compatibility:

• Compatible with anionic/nonionic surfactants, but avoid direct mixing with cationic surfactants.

• Do not mix with strong oxidizers (e.g., hypochlorite) without testing.

• Regulatory Compliance:

• Some regions restrict phosphorus content (e.g., EU Detergent Regulation).

• Consider P-free alternatives (e.g., GLDA, IDS) for eco-friendly formulations.

5. Storage & Handling

• Shelf Life: 24 months in sealed containers at <30°C.

• Packaging: 25 kg HDPE drums or IBC totes (liquid), 25 kg bags (powder).

Conclusion

ATMP·Na₄ is a versatile ingredient in detergents, personal care, and industrial cleaners, offering superior scale inhibition, metal ion control, and stability. While highly effective, formulators should assess phosphorus regulations and explore eco-friendly alternatives where needed.
