In plain English

This ingredient is a type of ester made from lauric acid (from coconut or palm oil) and glutamic acid (an amino acid), combined with branched-chain alcohols. It feels silky and lightweight on the skin, providing moisture and a smooth finish without heavy oiliness. It's often used in products for sensitive or acne-prone skin because it's very gentle and unlikely to cause breakouts.

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 Bis-Hexyldecyl/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.

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 created by reacting lauric acid with glutamic acid and long-chain alcohols (hexyldecyl and octyldodecyl). It belongs to the family of amino-acid-based emollients, known for their mildness and skin compatibility.

How it works

It sits on the skin's surface, forming a thin, breathable film that helps reduce water loss (trans-epidermal water loss, or TEWL) while imparting a soft, velvety feel. Its molecular structure allows it to spread easily and absorb quickly, making it an excellent texture enhancer in formulations.

Pros

Lightweight feel

Unlike heavier oils, this ester absorbs quickly without leaving a greasy residue, making it ideal for daytime moisturizers and serums.

Gentle for sensitive skin

Derived from amino acids, it has a low irritation potential and is often used in formulations for reactive or easily irritated skin.

Cons and cautions

Sustainability concerns

The lauric acid may come from palm oil, which has environmental and ethical issues unless certified sustainable.

Limited research

While safe based on similar ingredients, there are fewer peer-reviewed studies specifically on this ester compared to more common emollients.

Best for

People with dry or dehydrated skin looking for a lightweight moisturizer
Those with sensitive or acne-prone skin who want a non-comedogenic emollient

Use caution if

Individuals with a known allergy to any component (very rare)

Usage tips

Look for products that list it in the middle to end of the ingredient list for a lightweight feel.

Pair with humectants like glycerin or hyaluronic acid for enhanced hydration.

Safety summary

Bis-Hexyldecyl/Octyldodecyl Lauroyl Glutamate is considered safe for use in cosmetics at typical concentrations. It has a low irritation and comedogenic risk, making it suitable for most skin types, including sensitive and acne-prone skin. No significant safety concerns have been reported in regulatory reviews.

Research notes

While specific studies on this exact ester are limited, the ingredient class of amino-acid-based emollients is well-documented for mildness and skin compatibility. Safety assessments by bodies like the Cosmetic Ingredient Review (CIR) have found similar esters to be safe. More research would strengthen the evidence base.

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 part of generally recognized safe ingredients). No concentration restrictions are typical.
Common uses: Moisturizers, Serums, Sunscreens, Makeup, Cleansers
Environmental note: The sourcing of lauric acid may involve palm oil; look for RSPO-certified or sustainably sourced versions to minimize environmental impact.

Good to know

This ingredient is often used as a replacement for silicones in 'silicone-free' formulations.
It is biodegradable and considered environmentally friendly compared to some synthetic alternatives.
