Ingredient review
Dioctyldodecyl Lauroyl Glutamate
INCI: Dioctyldodecyl Lauroyl Glutamate
A lightweight, non-greasy emollient derived from amino acids that helps soften skin without clogging pores.
In plain English
This ingredient is a type of oil-like substance made from a fatty alcohol (dioctyldodecyl) and an amino acid (glutamic acid) combined with lauric acid from coconut or palm oil. It spreads easily on the skin, feels silky and non-greasy, and helps keep the skin barrier healthy by reducing water loss. Because it's based on an amino acid, it's very gentle and unlikely to cause irritation or breakouts.

Quick decision guide
Easy yes for most routines
Dioctyldodecyl 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 Dioctyldodecyl 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
Dioctyldodecyl Lauroyl Glutamate is a diester of dioctyldodecanol and lauroyl glutamic acid. It is a semi-synthetic emollient that mimics the skin's natural lipids, providing a smooth, velvety feel.
How it works
It sits on the surface of the skin, forming a thin, breathable film that locks in moisture and fills in rough patches. This reduces transepidermal water loss (the water that evaporates from your skin) and makes the skin feel softer and more supple. It also helps other ingredients spread evenly.
Pros
Ultra-gentle for sensitive skin
Derived from amino acids, it has a very low irritation score and is well-tolerated even by those with eczema or rosacea.
Non-comedogenic and lightweight
Unlike heavier oils, it won't clog pores or feel greasy, making it suitable for oily and acne-prone skin types.
Cons and cautions
Not a standalone hydrator
It works best as part of a moisturizing formula with humectants like glycerin or hyaluronic acid to draw water into the skin.
Potential palm oil sourcing
Lauric acid is often sourced from palm or coconut oil; look for sustainably sourced versions if this is a concern.
Best for
- People with dry or dehydrated skin
- Those with sensitive or reactive skin
- Anyone looking for a lightweight moisturizer
Use caution if
- Individuals with a known allergy to any component (rare)
Usage tips
Safety summary
Considered very safe for topical use. The Cosmetic Ingredient Review (CIR) panel has evaluated similar amino-acid esters and found them safe in current usage concentrations. Rare allergic reactions are possible but extremely uncommon.
Research notes
While not extensively studied in clinical trials on its own, amino-acid-based emollients are well-established in dermatology for their gentle skin conditioning and barrier-supporting properties. Safety data from the CIR and industry use support its low-risk profile.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics worldwide, including by the FDA (as a cosmetic ingredient) and under EU CosIng. No concentration restrictions are typical.
- Common uses
- Moisturizers, Serums, Sunscreens, Makeup, Lip products
- Environmental note
- The lauric acid component may be derived from palm oil. Look for brands that use RSPO-certified sustainable palm oil or coconut-derived alternatives.
Good to know
- It is often used in 'skin-identical' formulas because its structure resembles natural skin lipids.
- It can help reduce the greasy feel of sunscreens.
