What Is Disodium Cocamido Mea-Sulfosuccinate?
Disodium Cocamido Mea-Sulfosuccinate is a mild surfactant made from coconut-derived fatty acids that have been reacted with monoethanolamine then linked to sulfosuccinic acid and finally neutralized with sodium. The result is a water-soluble salt that carries a negative charge, which helps it lift away dirt and oil. Cosmetic chemists began working with sulfosuccinate surfactants in the 1970s when consumers asked for cleansers that were gentler than traditional soaps. Today this ingredient is produced in large batches by combining purified coconut fatty acids with the other reactants under controlled heat and pH, followed by filtration and spray drying.
You will most often spot Disodium Cocamido Mea-Sulfosuccinate in shampoos, body washes, facial cleansers, bubble baths, baby washes, shaving creams and even some makeup removers. Its balance of mildness and lather makes it a versatile choice for daily-use formulas that need to clean without stripping the skin or hair.
Disodium Cocamido Mea-Sulfosuccinate’s Cosmetic Benefits/Uses
Formulators choose this ingredient because it performs several helpful jobs at once.
- Cleansing: Breaks up sebum, sweat and product buildup so they rinse away easily, leaving skin and hair feeling fresh
- Foaming: Creates a rich, dense lather that helps spread the product evenly and gives a satisfying sensory feel
- Skin conditioning: Deposits a light conditioning film that can reduce dryness and improve softness after rinsing
- Hydrotrope: Helps keep oils, fragrances and other hard-to-dissolve ingredients evenly mixed in water-based formulas, which improves product clarity and stability
Who Can Use Disodium Cocamido Mea-Sulfosuccinate

Comedogenic Rating
Rating: 1/5
Disodium Cocamido Mea-Sulfosuccinate is water soluble and rinses away easily, so it does not linger on skin to block pores. It is derived from lightweight coconut fatty acids that are modified to be highly cleansing rather than oily. For these reasons formulators consider it very low risk for clogging pores.
Suitable for acne-prone or breakout-prone skin.
Because it is almost always used in rinse-off products like cleansers and shampoos, any tiny residue left behind is unlikely to cause problems even on oily skin.
Summary
Disodium Cocamido Mea-Sulfosuccinate acts as a gentle multitasker. It lifts away dirt and oil (cleansing), whips up a creamy lather that helps spread the product (foaming), leaves a soft feel after rinsing (skin conditioning) and keeps tricky ingredients blended in watery formulas (hydrotrope). Its mild nature makes it a favorite in everyday shampoos, body washes, facial cleansers and baby products, especially for brands that want a plant-based surfactant.
The ingredient is widely used because it offers a good balance of gentleness and performance at an affordable cost. You will find it in many mid-range and mass-market products, though it is not as famous as sulfate surfactants that have been around longer.
Current research shows it is safe in typical rinse-off amounts with only rare reports of irritation or allergy. As with any new skincare or haircare product it is wise to do a small patch test first to be sure your skin agrees with the overall formula.
