Ingredient review
Dioctyldodeceth-2 Lauroyl Glutamate
INCI: DIOCTYLDODECETH-2 LAUROYL GLUTAMATE
A mild, amino-acid-based surfactant that cleanses without stripping the skin barrier, ideal for sensitive skin.
In plain English
This ingredient is a gentle cleanser made by combining fatty alcohols (dioctyldodeceth-2) with lauroyl glutamate, an amino acid derivative. It helps remove dirt and oil without leaving skin feeling tight or dry. Think of it as a kinder alternative to harsh soaps—it respects your skin’s natural moisture barrier while still getting the job done.

Quick decision guide
Easy yes for most routines
Dioctyldodeceth-2 Lauroyl Glutamate 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 Dioctyldodeceth-2 Lauroyl Glutamate.
- 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
A semi-synthetic surfactant created by esterifying dioctyldodeceth-2 (a fatty alcohol ethoxylate) with lauroyl glutamic acid (an amino acid derivative). It belongs to the family of glutamate-based surfactants, which are prized for their mildness and biodegradability.
How it works
In a formula, it reduces the surface tension between water and oil, allowing them to mix so that dirt and sebum can be rinsed away. Its large molecular structure and amino acid backbone make it less penetrating and less irritating than traditional sulfate surfactants. It also helps stabilize emulsions, keeping oil and water phases blended in creams and lotions.
Pros
Ultra-mild cleansing
Its amino acid structure makes it one of the gentlest surfactants available, reducing the risk of irritation and barrier damage even with daily use.
Skin-friendly pH
It typically works at a pH close to skin’s natural 5.5, helping maintain a healthy acid mantle and microbiome.
Cons and cautions
Lower foam volume
It produces a creamy, low-lather foam rather than big bubbles, which may feel less satisfying to those accustomed to sulfate-based cleansers.
Higher formulation cost
Products containing this ingredient are often pricier due to the more complex synthesis and raw material costs.
Best for
- People with dry, sensitive, or eczema-prone skin who need a non-stripping cleanser
- Anyone looking to switch to milder, amino-acid-based cleansing products
Use caution if
- Those who prefer high-foaming, bubbly cleansers may find it too low-lather
Usage tips
Safety summary
Dioctyldodeceth-2 Lauroyl Glutamate is considered safe for use in cosmetics at typical concentrations. It has a low irritation and comedogenic risk, making it suitable for sensitive skin. No significant safety concerns have been reported in regulatory or dermatological literature.
Research notes
Amino-acid-based surfactants like this one are well-documented in cosmetic science for their mildness and skin compatibility. While specific studies on this exact compound are limited, the broader class of glutamate surfactants has been shown to cause less protein denaturation and cell damage than sulfates. Evidence supports its safety and efficacy as a gentle cleanser.
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 ingredients). No specific restrictions at typical use levels.
- Common uses
- Facial cleansers, Makeup removers, Shampoos, Body washes
- Environmental note
- This ingredient is biodegradable and has a lower environmental impact than many conventional surfactants, making it a more eco-friendly choice in rinse-off products.
Good to know
- Often listed alongside other mild surfactants like cocamidopropyl betaine to boost foam without increasing irritation.
- It is considered biodegradable and less harmful to aquatic life compared to many traditional surfactants.
