Ingredient review
Phytosteryl/Octyldodecyl Lauroyl Glutamate
INCI: PHYTOSTERYL/OCTYLDODECYL LAUROYL GLUTAMATE
A gentle, plant-derived emollient that helps soften skin and improve the feel of formulations without clogging pores.
In plain English
This ingredient is a fancy ester made from plant sterols (like from soy or pine), a fatty alcohol, and an amino acid. In plain terms, it's a skin-friendly oil-like substance that helps moisturize and smooth the skin's surface. It also helps blend oil and water in a formula, making creams feel richer and more spreadable.

Quick decision guide
Useful, but context matters
Phytosteryl/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/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 combining phytosterols (plant-derived compounds similar to cholesterol), octyldodecanol (a branched fatty alcohol), and lauroyl glutamate (a fatty acid linked to the amino acid glutamic acid). It is produced through chemical esterification.
How it works
It sits on the skin's surface, forming a thin, non-greasy film that reduces water loss (trans-epidermal water loss, or TEWL) and makes the skin feel soft and smooth. As an emulsifier, it helps stabilize mixtures of oil and water, improving product texture and spreadability.
Pros
Gentle on skin
With low irritation and comedogenic ratings, it's unlikely to cause breakouts or stinging, making it suitable for sensitive and acne-prone skin types.
Improves product feel
It helps creams and lotions spread smoothly and feel silky without leaving a heavy or greasy residue, enhancing the user experience.
Cons and cautions
Limited direct research
Most safety and efficacy data come from studies on similar esters or individual components, not this exact compound, so its benefits are inferred.
Not a primary humectant
It works mainly as an emollient and does not actively draw water into the skin like glycerin or hyaluronic acid, so it's best used in combination with humectants.
Best for
- People with dry or dehydrated skin looking for a lightweight emollient
- Those with sensitive or acne-prone skin who want a non-comedogenic moisturizer
Use caution if
- Individuals with a known allergy to any of its components (rare)
Usage tips
Safety summary
Considered safe for use in cosmetics at typical concentrations. The Cosmetic Ingredient Review (CIR) panel has evaluated similar esters and found them safe. Irritation and sensitization potential is very low.
Research notes
Direct studies on this specific ester are scarce, but the individual components (phytosterols, fatty alcohols, amino acid derivatives) have a strong safety profile and well-documented emollient benefits. Most evidence is extrapolated from related ingredients.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. It is not classified as a drug ingredient.
- Common uses
- Moisturizers, Anti-aging creams, Serums, Lip products
- Environmental note
- The plant sterols are typically sourced from sustainable crops like soy or pine, but the esterification process involves chemical synthesis, so it's not fully natural.
Good to know
- Phytosterols are structurally similar to cholesterol, a natural part of the skin's barrier, which may help reinforce the skin's protective layer.
- This ingredient is often used in 'natural' or 'plant-based' formulations because the sterols are derived from plants.
