Ingredient review
Lysine Cocoate
INCI: Lysine Cocoate
A mild, amino-acid-based surfactant that cleanses without stripping the skin's natural moisture barrier.
In plain English
Lysine Cocoate is a gentle cleansing ingredient made from lysine (an amino acid found in proteins) and fatty acids from coconut oil. It helps remove dirt, oil, and makeup without leaving your skin feeling tight or dry. Unlike harsher soaps, it works with your skin's natural pH and is less likely to cause irritation.

Quick decision guide
Useful, but context matters
Lysine Cocoate 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 Lysine Cocoate.
- 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
Lysine Cocoate is a surfactant created by combining the amino acid lysine with coconut oil fatty acids. It belongs to the family of amino-acid-based cleansers, known for their mildness and compatibility with sensitive skin.
How it works
In a cosmetic product, Lysine Cocoate reduces the surface tension of water, allowing it to mix with oil and dirt so they can be rinsed away. Its molecular structure is similar to natural skin components, which helps it clean gently without disrupting the skin's protective barrier.
Pros
Ultra-gentle on skin
Lysine Cocoate cleanses effectively without stripping natural oils, making it ideal for daily use on sensitive or dry skin.
pH-friendly
It works well at a pH close to skin's natural level (around 5.5), reducing the risk of irritation or disruption of the skin barrier.
Cons and cautions
Lower foam volume
Compared to sulfates like SLS, Lysine Cocoate produces less foam, which some users may perceive as less effective even though it cleans just as well.
Higher cost
Amino-acid-based surfactants are more expensive to produce, which can increase the price of products containing them.
Best for
- People with dry or sensitive skin
- Those looking for a sulfate-free cleanser
- Anyone seeking a gentle daily face wash
Use caution if
- Individuals with known allergies to coconut-derived ingredients (rare)
Usage tips
Safety summary
Lysine Cocoate is considered safe for use in cosmetics. It has low irritation and sensitization potential, making it suitable for sensitive skin. No significant safety concerns have been reported in standard cosmetic use.
Research notes
Amino-acid surfactants like Lysine Cocoate are well-studied for their mildness and skin compatibility. Research indicates they cause less barrier disruption and irritation compared to traditional anionic surfactants. However, specific studies on Lysine Cocoate alone are limited, with most evidence extrapolated from similar amino-acid surfactants.
Common label clues
- Typical concentration
- 1-10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Facial cleansers, Body washes, Shampoos, Micellar waters
- Environmental note
- Derived from renewable plant sources (coconut oil and lysine from fermentation). It is biodegradable and has a lower environmental impact compared to petroleum-based surfactants.
Good to know
- Lysine Cocoate is often listed alongside other amino-acid surfactants in 'sulfate-free' formulas.
- It is considered biodegradable and more environmentally friendly than some traditional surfactants.
