Ingredient review
Brassicyl Aminolaurate Esylate
INCI: BRASSICYL AMINOLAURATE ESYLATE
A mild, plant-derived surfactant that effectively cleanses while respecting the skin barrier — ideal for sensitive or dry skin.
In plain English
Brassicyl Aminolaurate Esylate is a gentle cleansing ingredient made from rapeseed (canola) oil and amino acids. Unlike harsh soaps that can strip your skin of its natural oils, this surfactant lifts away dirt, oil, and makeup without leaving your face feeling tight or dry. It's often used in sulfate-free cleansers and is well-tolerated by sensitive skin.

Quick decision guide
Easy yes for most routines
Brassicyl Aminolaurate Esylate 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 Brassicyl Aminolaurate Esylate.
- 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 surfactant created by reacting fatty acids from rapeseed oil with amino acids (specifically lauric acid and aminolaurate), then converting to an esylate salt. It belongs to the class of amino-acid-based surfactants known for their mildness.
How it works
In a cleanser, it reduces the surface tension between water and oil, allowing impurities to be rinsed away. Its large molecular structure and gentle ionic charge mean it interacts minimally with skin proteins, so it cleans without disrupting the skin's moisture barrier or causing irritation.
Pros
Skin barrier friendly
Its mild cleansing action helps preserve natural oils and ceramides, reducing the risk of dryness and irritation after washing.
Plant-based and biodegradable
Made from rapeseed oil, it offers a renewable alternative to harsher petrochemical surfactants and breaks down more easily in the environment.
Cons and cautions
Low foam profile
Produces a creamy, low-lather texture that may not satisfy users who associate rich foam with effective cleansing.
Limited heavy-duty cleansing
Struggles to dissolve long-wear or waterproof makeup on its own, often requiring a double-cleansing step or combination with other surfactants.
Best for
- People with dry, sensitive, or eczema-prone skin
- Anyone looking for a sulfate-free, gentle daily cleanser
Use caution if
- Those who prefer a high-foam, squeaky-clean feel may find it too mild
Usage tips
Safety summary
Brassicyl Aminolaurate Esylate is considered safe for use in cosmetics at typical concentrations. It has a low irritation and comedogenic risk, making it suitable for sensitive skin. No significant safety concerns have been reported in regulatory reviews.
Research notes
Amino-acid-based surfactants like this one are well-studied for their mildness and skin compatibility. While specific studies on Brassicyl Aminolaurate Esylate are limited, the broader class is supported by dermatological research showing reduced irritation compared to traditional sulfates.
Common label clues
- Typical concentration
- 1–15% in rinse-off cleansers
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. No known restrictions.
- Common uses
- Facial cleansers, Body washes, Shampoos, Micellar waters
- Environmental note
- Derived from rapeseed oil, a renewable resource. Biodegradability data is favorable, but always check individual product formulations for full environmental impact.
Good to know
- Often listed near the top of ingredient lists in sulfate-free cleansers.
- Can be combined with other mild surfactants to adjust foam and cleansing power.
