Cholesteryl/Behenyl/Octyldodecyl Lauroyl Glutamate

INCI: CHOLESTERYL/BEHENYL/OCTYLDODECYL LAUROYL GLUTAMATE

A gentle, multi-chain ester that helps soften skin and improve product texture without clogging pores.

beautyskincareemollient

In plain English

This ingredient is a blend of fatty chains (from cholesterol, behenyl alcohol, and octyldodecanol) attached to an amino-acid derivative (lauroyl glutamate). In simple terms, it acts like a skin-friendly oil that spreads easily, helps other ingredients mix together, and leaves skin feeling smooth and soft. It is very similar to the natural fats found in your skin's outer layer, so it tends to be well-tolerated even by sensitive skin.

Quick decision guide

Useful, but context matters

Cholesteryl/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.

  1. Step 1Start with the score, then check the irritation and clogging risk before judging Cholesteryl/Behenyl/Octyldodecyl Lauroyl Glutamate.
  2. Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
  3. 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

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

moderate

There 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 surfactant) with three different fatty alcohols: cholesterol (a natural skin lipid), behenyl alcohol (a long-chain fatty alcohol from plants), and octyldodecanol (a branched-chain emollient). The result is a multi-functional ingredient that mimics the skin's own lipid barrier.

How it works

When applied to the skin, this ingredient sits on the surface and fills in gaps between skin cells, helping to reinforce the skin barrier. It also reduces water loss (transepidermal water loss, or TEWL) by forming a thin, breathable film. In formulas, it helps oil and water phases blend together, creating a stable, creamy texture.

Pros

Barrier-friendly

Because it contains cholesterol and long-chain fatty alcohols, it closely mimics the skin's natural lipids, helping to repair and maintain a healthy moisture barrier.

Texture enhancer

It gives creams and lotions a smooth, velvety feel without leaving a heavy or sticky residue, making it a favorite in luxury formulations.

Cons and cautions

Potential heaviness for oily skin

In high concentrations, the blend of fatty chains may feel too rich for those with very oily or acne-prone skin, potentially contributing to congestion.

Limited direct research

Most safety and efficacy data come from studies on similar esters or individual components, not the exact blend itself.

Best for

  • People with dry or dehydrated skin looking for barrier support
  • Anyone who prefers rich, creamy moisturizers without a greasy finish

Use caution if

  • Those with extremely oily skin who avoid any lipid-rich ingredients

Usage tips

Look for this ingredient in the middle to end of the ingredient list; it is effective at low concentrations.
Pair with humectants like glycerin or hyaluronic acid for balanced hydration.
Use in your night routine if you have dry skin, as it provides longer-lasting moisture.

Safety summary

This ingredient is considered safe for cosmetic use at typical concentrations. It has a low irritation and comedogenic risk, making it suitable for most skin types, including sensitive skin. No significant safety concerns have been reported in regulatory reviews.

Research notes

While direct studies on this exact blend are limited, the individual components (cholesterol, behenyl alcohol, octyldodecanol, and lauroyl glutamate) have been extensively studied and are well-tolerated. The combination is designed to mimic skin lipids, and similar ester blends have shown barrier-repair benefits in clinical settings.

Common label clues

Typical concentration
0.5–5%
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.
Common uses
Moisturizers, Anti-aging creams, Lip products, Hair conditioners
Environmental note
The fatty alcohols are typically derived from plant sources (palm or coconut), so sustainability depends on sourcing practices. The ingredient is not known to be bioaccumulative or toxic to aquatic life.

Good to know

  • This ingredient is often used as a replacement for silicones in 'silky' textures.
  • It is compatible with both water-in-oil and oil-in-water emulsions.
