Ingredient review
Sodium Lauroyl Ethylenediamine Triacetate
INCI: Sodium Lauroyl Ethylenediamine Triacetate
A gentle chelating agent that helps preserve formula integrity and boost antioxidant performance without the irritation of stronger alternatives.
In plain English
This ingredient acts like a magnet for tiny metal particles (like iron or copper) that can sneak into your skincare from water or packaging. By grabbing and holding onto these metals, it stops them from breaking down other ingredients or causing unwanted reactions. Think of it as a bodyguard for your product—keeping it fresh and effective longer. It's similar to EDTA but considered milder and more biodegradable.

Quick decision guide
Useful, but context matters
Sodium Lauroyl Ethylenediamine Triacetate is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Sodium Lauroyl Ethylenediamine Triacetate.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
Sodium Lauroyl Ethylenediamine Triacetate is a synthetic chelating agent derived from ethylenediamine and lauric acid. It is designed to bind metal ions in cosmetic formulations, preventing them from catalyzing degradation or discoloration.
How it works
In a cosmetic product, this ingredient latches onto metal ions (like calcium, magnesium, iron, or copper) that are present in water or raw materials. By forming stable complexes with these metals, it neutralizes their ability to trigger oxidation, rancidity, or color changes. This helps preserve the product's texture, scent, and efficacy over time.
Pros
Gentle on skin
Compared to traditional EDTA, this ingredient is less likely to cause irritation or dryness, making it suitable for sensitive skin formulas.
Boosts formula stability
By binding metals, it helps preserve the effectiveness of active ingredients like antioxidants, so your products work better for longer.
Cons and cautions
Limited research
There are fewer independent studies on this specific chelator compared to EDTA, so long-term safety data is less robust.
May not suit all formulas
In very hard water or high-metal environments, it may require higher concentrations to be effective, which could affect product feel.
Best for
- Anyone using products with sensitive antioxidants like vitamin C or retinol
- People with hard water who want better lather and rinse-off from cleansers
Use caution if
- Those with known allergies to ethylenediamine derivatives (rare)
Usage tips
Safety summary
Sodium Lauroyl Ethylenediamine Triacetate is considered safe for use in cosmetics at typical concentrations. It is less irritating than some other chelating agents and is generally well-tolerated. Rare allergic reactions are possible in individuals sensitive to ethylenediamine derivatives.
Research notes
Research supports its effectiveness as a chelating agent in cosmetic formulations, with some studies indicating better biodegradability than EDTA. However, long-term skin safety data is less extensive than for more established chelators.
Common label clues
- Typical concentration
- 0.05% to 0.5%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. Generally recognized as safe when used within typical concentrations.
- Common uses
- Cleansers, Toners, Serums, Moisturizers
- Environmental note
- This ingredient is considered more biodegradable than traditional EDTA, which can persist in the environment. However, its full environmental impact is still being studied.
Good to know
- It is often used as a replacement for EDTA in 'clean' or 'green' beauty formulations due to its better biodegradability.
- On ingredient labels, it may appear near the end of the list because it is used in very small amounts.
