EDTA NA2

Benefits

• In Cosmetics & Personal Care:

  • Stabilizes products by preventing metal-catalyzed oxidation.

  • Extends shelf life of creams, shampoos, soaps, and lotions.

  • Enhances foaming and cleaning performance in shampoos and soaps.

  • Helps prevent rancidity and discoloration of oils in formulations.

• In Pharmaceuticals:

  • Used to preserve stability of medicines and injections.

• In Food Industry:

  • (When permitted as Calcium Disodium EDTA) prevents discoloration and flavor changes caused by metals.

• In Laboratories & Industry:

  • Acts as a reagent for analytical testing.

  • Prevents scale formation and metal contamination in water systems.

How to Use It (Detailed)

In Cosmetics & Personal Care

• Dosage/Concentration: Usually added at 0.05% – 0.2% of the total formulation (very small amounts are enough).

• Formulation Stage: Added during the water phase of formulations since it is highly water-soluble.

• Purpose:

  • Prevents discoloration and rancidity of creams, lotions, and oils.

  • Stabilizes vitamin C, essential oils, and botanical extracts by reducing oxidation.

  • Improves the foaming and cleansing ability of shampoos, face washes, and soaps.

• Examples:

  • Shampoos & conditioners → prevents hard water ions from affecting performance.

  • Creams & lotions → keeps color, texture, and scent stable.

  • Liquid soaps & cleansers → boosts effectiveness by softening water.

In Pharmaceuticals (Professional/Controlled use)

• Used in injectable solutions and eye drops as a stabilizer.

• Prevents oxidation of active drug ingredients.

• Always measured precisely in a lab or medical setting.

In Food Industry (only specific forms like Calcium Disodium EDTA are approved)

• Prevents color loss and rancidity in canned foods, dressings, and beverages.

• Usage is tightly regulated and always in trace amounts.

In Laboratories & Industrial Applications

• Used as a reagent to bind calcium and magnesium ions in water hardness testing.

• Helps prevent scale buildup in boilers and cooling systems.

• Used in textile and paper industries to stop metal contamination during processing.

In short:

• For cosmetics/skincare, dissolve in the water phase at 0.05% – 0.2%.

• For industrial/lab use, concentrations vary based on the application.

• For medical/food use, it must follow strict regulations — not DIY.

  Safety & Precautions

  • Safe for topical and cosmetic use in the low concentrations typically used (regulated by cosmetic safety guidelines).

  • Not meant for direct consumption in its raw form.

  • Overuse or ingestion may cause nausea, mineral depletion, or kidney strain.

  • Should be avoided during pregnancy and breastfeeding unless medically approved.

  • People with kidney conditions should not be exposed to high doses.

  • Always handle with care in raw form (powder) — use gloves and avoid inhalation.

  • Store in a cool, dry, sealed container away from moisture.
