Ingredient review
Phytosteryl/Behenyl/Octyldodecyl Lauroyl Glutamate
INCI: PHYTOSTERYL/BEHENYL/OCTYLDODECYL LAUROYL GLUTAMATE
A gentle, multi-chain ester that helps moisturize and support the skin barrier without feeling greasy.
In plain English
This ingredient is a blend of fatty alcohols (from plants and synthetic sources) attached to an amino acid derivative. It acts like a skin-friendly oil that softens the skin and helps other ingredients spread evenly. Because it mimics natural skin lipids, it can help strengthen the skin's outer barrier without clogging pores or causing irritation.

Quick decision guide
Useful, but context matters
Phytosteryl/Behenyl/Octyldodecyl 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 Phytosteryl/Behenyl/Octyldodecyl 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 ester made by combining lauroyl glutamate (an amino acid-based compound) with three different fatty alcohols: phytosterol (from plants), behenyl alcohol (from rapeseed or synthetic), and octyldodecanol (a branched-chain alcohol). The result is a waxy, non-greasy emollient.
How it works
When applied to the skin, it forms a thin, breathable film that reduces water loss (transepidermal water loss, or TEWL) and helps keep the skin hydrated. Its structure is similar to the skin's natural lipids, so it integrates into the outer layer, improving barrier function and leaving a smooth, soft feel.
Pros
Non-greasy moisture
Unlike heavy oils, this ester provides a soft, silky feel on the skin while still delivering deep hydration.
Barrier-friendly
Its structure mimics natural skin lipids, helping to reinforce the skin's protective barrier and reduce moisture loss.
Cons and cautions
May feel heavy for oily skin
In high concentrations, it can feel too rich for people with very oily or acne-prone skin, potentially leading to congestion.
Semi-synthetic origin
While effective, it is not a purely natural ingredient, which may be a consideration for those seeking 100% natural formulations.
Best for
- People with dry or dehydrated skin looking for a non-greasy moisturizer
- Those with compromised skin barriers (e.g., from over-exfoliation or harsh weather)
Use caution if
- Individuals with extremely oily skin who prefer lightweight, gel-based products
Usage tips
Safety summary
This ingredient has a strong safety profile with very low irritation and comedogenic potential. It is well-tolerated by most skin types, including sensitive skin. No significant safety concerns have been reported in cosmetic use.
Research notes
While specific studies on this exact ester are limited, the individual components (phytosterols, behenyl alcohol, and lauroyl glutamate) are well-studied and recognized as safe and effective emollients and barrier-repair agents. The combination is designed to optimize skin feel and compatibility.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics globally, including by the EU CosIng database and the US FDA (as a cosmetic ingredient). No known restrictions.
- Common uses
- Moisturizers, Anti-aging creams, Barrier repair products, Lip balms
- Environmental note
- The phytosterol portion is typically derived from plant oils (e.g., soybean or rapeseed), making it a renewable resource. The synthetic alcohols are produced via industrial processes, but overall the ingredient is considered low-impact.
Good to know
- This ingredient is often used in 'skin barrier repair' products because of its lipid-mimicking properties.
- It is considered very safe and is commonly used in leave-on products like creams and lotions.
