What Is Diammonium Lauramido-Mea Sulfosuccinate?
Diammonium Lauramido-Mea Sulfosuccinate is a gentle, water-soluble surfactant made from lauric acid, a fatty acid usually sourced from coconut or sustainable palm oil. Chemically it is the diammonium salt of a sulfonated succinic acid ester, created by linking lauric acid to monoethanolamine, attaching a succinate group then neutralizing the molecule with ammonia. This process yields a large, softly charged molecule that cleanses without stripping skin or hair.
The ingredient gained popularity in the late 1970s when formulators began searching for alternatives to harsher sulfates. Because it provides rich lather yet remains mild, it soon found a place in sulfate-free and baby care products. Today it is produced in modern reactors where temperature, pH and pressure are carefully controlled to limit by-products and ensure batch-to-batch consistency.
You will most often see Diammonium Lauramido-Mea Sulfosuccinate in shampoos, facial cleansers, body washes, bubble baths, micellar waters and other rinse-off products that aim for a creamy foam without irritation.
Diammonium Lauramido-Mea Sulfosuccinate’s Cosmetic Benefits/Uses
This versatile ingredient supports a formula in more than one way:
- Cleansing – Acts as a mild surfactant that loosens oil, sweat and product buildup so they can be rinsed away while helping the formula create a dense, cushiony lather that feels pleasant on skin and hair
- Hydrotrope – Improves the solubility of fragrances, essential oils and other surfactants which keeps the final product clear, stable and free of sediment even at lower water levels
Who Can Use Diammonium Lauramido-Mea Sulfosuccinate
Thanks to its mild nature, this surfactant suits nearly all skin and hair types including sensitive, dry, oily and combination skin. It cleanses without leaving a tight or squeaky feel so even those prone to irritation often tolerate it well. There are no known concerns for acne-prone skin or conditions such as eczema when the ingredient is part of a balanced formula.
Diammonium Lauramido-Mea Sulfosuccinate is typically sourced from coconut or palm oil and neutralized with synthetic ammonia, which makes it suitable for vegans and vegetarians. No animal-derived raw materials are needed to produce the ingredient or its common preservatives.
Current safety data shows no reproductive or developmental risks, so products containing this surfactant are generally considered safe for pregnant or breastfeeding individuals. This is not medical advice and anyone who is expecting or nursing should consult a doctor before starting a new personal care routine to be sure it fits their specific needs.
The molecule does not absorb UV light or make skin more reactive to the sun, so it is not linked to photosensitivity. It is also free of known allergens like gluten soy or nuts, though the final product’s full ingredient list should always be checked if you have specific allergies.
Potential Side Effects/Adverse Reactions
Reactions to topical Diammonium Lauramido-Mea Sulfosuccinate can vary from person to person. The points below outline potential side effects yet most users will not experience them when the ingredient is properly formulated.
- Mild eye stinging if a high-foaming shampoo or wash accidentally gets into the eyes
- Temporary skin dryness when used in very high concentrations or left on the skin without rinsing
- Contact irritation in the rare event of individual sensitivity to coconut or palm-derived fatty acids
- Scalp or skin redness when combined with other strong surfactants that raise overall cleansing power
If you notice burning itching or persistent redness after using a product containing this ingredient discontinue use and seek medical advice if symptoms do not improve.
Comedogenic Rating
Rating: 0 / 5
Diammonium Lauramido-Mea Sulfosuccinate is a large, highly water-soluble surfactant that stays on the surface of skin or hair and is designed to rinse away quickly. It has no oily or waxy residue and does not penetrate follicles, so it earns the lowest possible score for pore clogging potential.
Suitable for individuals who are prone to acne or breakouts.
Because the ingredient is almost always used in wash-off products, contact time with skin is brief which further lowers any risk of congestion.
Summary
Diammonium Lauramido-Mea Sulfosuccinate acts as a mild cleanser and hydrotrope. Its amphiphilic structure grabs onto dirt and oil then lifts them into water so they rinse away easily, while its hydrotropic action keeps other ingredients evenly dissolved for a clear stable formula. The result is rich foam without the harshness associated with traditional sulfates.
The ingredient is popular in sulfate-free shampoos, gentle face washes and baby products because it balances effective cleansing with low irritation. It is less common in leave-on items where foaming is not needed.
Current data shows it is low risk for sensitization, toxicity or pore blockage, making it safe for most users and skin types. As with any new cosmetic, it is still wise to perform a small patch test when trying a product that contains this surfactant to be sure it agrees with your skin.
