Ingredient review
Cocamidopropyl Dimethylammonium C8-16 Isoalkylsuccinyl Lactoglobulin Sulfonate
INCI: COCAMIDOPROPYL DIMETHYLAMMONIUM C8-16 ISOALKYLSUCCINYL LACTOGLOBULIN SULFONATE
A gentle conditioning surfactant that cleanses without stripping, but its complex structure means limited independent safety data.
In plain English
This ingredient is a hybrid molecule that combines a mild cleansing agent from coconut oil with a modified milk protein. It helps remove dirt and oil while leaving hair and skin feeling soft and smooth, rather than tight or dry. Think of it as a gentle soap that also moisturizes.

Quick decision guide
Useful, but context matters
Cocamidopropyl Dimethylammonium C8-16 Isoalkylsuccinyl Lactoglobulin Sulfonate can be useful, but watch for some irritation potential.
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 Cocamidopropyl Dimethylammonium C8-16 Isoalkylsuccinyl Lactoglobulin Sulfonate.
- 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
moderateCan bother some users, especially with frequent use, damaged skin, or strong companion ingredients.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A semi-synthetic surfactant and conditioning agent created by chemically linking a coconut-derived cleansing molecule (cocamidopropyl dimethylamine) with a modified milk protein (lactoglobulin sulfonate) and a fatty acid chain. It is designed to be milder than traditional sulfates.
How it works
The molecule has a water-loving head and an oil-loving tail, allowing it to surround and lift away dirt and excess oil. The protein portion helps the molecule deposit onto hair or skin, reducing irritation and leaving a smooth, conditioned feel.
Pros
Gentle on skin
Unlike harsh sulfates, this ingredient cleanses without stripping the skin's natural moisture barrier, making it suitable for daily use on sensitive or dry skin.
Improves hair feel
The protein component helps condition hair during washing, reducing frizz and leaving strands softer and more manageable without extra products.
Cons and cautions
Limited research
Because this is a specialized, complex molecule, there are fewer peer-reviewed studies on its long-term effects compared to more common surfactants.
Potential allergen
People with coconut or milk protein allergies may react to this ingredient, though such reactions are rare in rinse-off products.
Best for
- People with dry or sensitive skin looking for a gentle cleanser
- Anyone wanting a shampoo that cleans without leaving hair brittle
Use caution if
- Individuals with known allergies to coconut-derived ingredients or milk proteins
Usage tips
Safety summary
Generally considered safe for use in rinse-off cosmetics at typical concentrations. The ingredient is designed to be mild, but individuals with coconut or milk protein allergies should exercise caution. The Cosmetic Ingredient Review (CIR) has not published a specific monograph for this exact compound, but related cocamidopropyl derivatives are deemed safe with use restrictions.
Research notes
Available evidence is mostly from manufacturer safety data and general surfactant research. No large-scale human studies exist specifically for this ingredient. Its mildness is inferred from its chemical structure and similarity to other gentle surfactants.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and other major markets. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Shampoos, Conditioners, Body washes, Facial cleansers
- Environmental note
- Derived from renewable coconut oil and milk byproducts, but the chemical modification process may have moderate environmental impact. Biodegradability data is limited.
Good to know
- This ingredient is often found in 'sulfate-free' or 'gentle' cleansers.
- Its long INCI name reflects its complex structure, but in practice it functions similarly to milder surfactants.
