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
A semi-synthetic surfactant made by combining lauryl alcohol (from coconut or palm oil) with ethylene oxide and citric acid. It belongs to the family of citrate esters, known for their mildness.
How it works
It works by reducing the surface tension between water and oil, allowing dirt and excess sebum to be rinsed away. Its citrate group helps maintain a gentle pH, making it less irritating than traditional sulfates.
Pros
Very gentle on skin
Unlike harsh sulfates, this surfactant cleans effectively without causing tightness or irritation, making it ideal for daily use on sensitive skin.
pH-friendly
Its citrate backbone helps keep the product's pH close to skin's natural level, reducing the risk of disrupting the acid mantle.
Cons and cautions
Potential trace impurities
As an ethoxylated ingredient, it may contain trace amounts of 1,4-dioxane if not properly purified during manufacturing. Reputable brands ensure purification.
Sustainability concerns
The lauryl alcohol source is often palm oil, which can be linked to deforestation unless certified sustainable.
Best for
- People with sensitive or dry skin
- Those looking for a sulfate-free cleanser
Use caution if
- Individuals with known allergies to ethoxylated ingredients (rare)
Usage tips
Safety summary
Disodium Laureth-7 Citrate is considered safe for use in cosmetics at typical concentrations. The main concern is trace 1,4-dioxane from ethoxylation, but reputable manufacturers purify to safe levels. It is non-irritating and non-comedogenic for most people.
Research notes
Studies on citrate-based surfactants show they are significantly milder than traditional sulfates and less damaging to skin barrier function. The Cosmetic Ingredient Review (CIR) panel has reviewed similar ethoxylated surfactants and found them safe when formulated properly.
Common label clues
- Typical concentration
- 1–10% in rinse-off products; lower in leave-on formulas
- Regulatory status
- Approved for use in cosmetics globally, including by the EU CosIng database and the US FDA (as part of generally recognized safe surfactant categories).
- Common uses
- Cleansers, Shampoos, Body washes, Facial washes
- Environmental note
- Biodegradable, but sourcing of palm-derived lauryl alcohol may have environmental impact. Look for RSPO-certified palm oil in the ingredient supply chain.
Good to know
- Disodium Laureth-7 Citrate is considered biodegradable and is often used in eco-friendly formulations.
- It is not a sulfate, so it won't produce the same lather as SLS, but it still cleans effectively.
