Ingredient review
Sodium Cocoyl Barley Amino Acids
INCI: Sodium Cocoyl Barley Amino Acids
A gentle, plant-based surfactant that cleanses without stripping the skin’s natural moisture barrier.
In plain English
This ingredient is a mild soap-like molecule made from coconut oil and proteins from barley. It helps lift dirt and oil from your skin so they can be rinsed away with water, but it’s much gentler than traditional harsh soaps. Because it’s derived from natural sources and has a low irritation potential, it’s often used in “gentle” or “sensitive skin” cleansers.

Quick decision guide
Easy yes for most routines
Sodium Cocoyl Barley Amino Acids 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 Sodium Cocoyl Barley Amino Acids.
- 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
Sodium Cocoyl Barley Amino Acids is a surfactant created by combining fatty acids from coconut oil with amino acids from barley protein. It belongs to the class of acyl amino acid surfactants, known for their mildness and compatibility with skin.
How it works
In a cleanser, this molecule has a water-loving head and an oil-loving tail. The tail grabs onto sebum, dirt, and makeup, while the head allows the whole complex to be rinsed away with water. Unlike sulfates, it does not disrupt the skin’s lipid barrier as aggressively, leaving skin feeling clean but not tight or dry.
Pros
Ultra-gentle cleansing
This surfactant cleans effectively without stripping the skin’s natural oils, making it ideal for daily use on sensitive or dry skin.
Plant-based and eco-friendly
Made from coconut oil and barley amino acids, it is biodegradable and has a lower environmental impact compared to petroleum-based surfactants.
Cons and cautions
Lower foam volume
It produces a creamy, low foam rather than big bubbles, which some users may mistake for less cleansing power.
Higher formulation cost
Products using this ingredient are often priced higher due to the cost of sourcing natural amino acids.
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 very rich, high-foam lather may find this too mild
Usage tips
Safety summary
Sodium Cocoyl Barley Amino Acids is considered safe for use in cosmetics. It has low irritation and comedogenic potential, and no significant safety concerns have been reported in standard concentrations.
Research notes
Acyl amino acid surfactants, including this one, are well-documented in cosmetic science as mild alternatives to sulfates. Studies show they cause less protein denaturation and lipid barrier disruption, though specific research on barley amino acid variants is limited.
Common label clues
- Typical concentration
- 1–15% in rinse-off products; lower in leave-on formulas
- Regulatory status
- Approved for cosmetic use globally; no known restrictions in the EU, US, or Japan.
- Common uses
- Facial cleansers, Body washes, Shampoos, Micellar waters
- Environmental note
- Biodegradable and derived from renewable agricultural sources, making it a more sustainable choice than many synthetic surfactants.
Good to know
- It is often combined with other mild surfactants to boost foam without increasing irritation.
- Barley amino acids also provide a slight moisturizing effect on the skin.
