What Is Disodium Laureth-12 Sulfosuccinate?
Disodium Laureth-12 Sulfosuccinate is a mild surfactant made by linking lauryl alcohol derived from coconut or palm oil with ethylene oxide to create a “laureth-12” chain, then attaching it to a sulfosuccinate group and neutralizing it with sodium. The finished ingredient is a water-soluble powder or liquid that carries a negative charge, which helps it lift away dirt and oil. It appeared in the late 1970s as chemists searched for gentler alternatives to traditional sulfates, and it quickly found a place in personal care because it cleans well without stripping skin or hair. You will most often spot it in face and body cleansers, sulfate-free shampoos, bubble baths, baby washes, makeup removers, exfoliating scrubs, bath bombs, dog grooming products and even some sheet mask essences where a bit of light cleansing action is helpful.
Disodium Laureth-12 Sulfosuccinate’s Cosmetic Benefits/Uses
This ingredient offers several helpful roles inside a formula
- Cleansing: Reduces the surface tension of water so oils, sweat and product buildup rinse away easily leaving skin and hair feeling fresh
- Foam Boosting: Creates a rich, stable lather that makes products more pleasant to use and helps spread the cleanser evenly
- Hydrotrope: Improves the solubility of otherwise hard-to-dissolve ingredients which keeps the formula clear and prevents separation
Who Can Use Disodium Laureth-12 Sulfosuccinate
This gentle cleanser is generally suitable for all skin types including dry, normal, oily and combination because it removes grime without the tight, squeaky feel that harsher surfactants often leave behind. Those with sensitive or eczema-prone skin usually tolerate it well since its larger molecular size keeps it from penetrating deeply, yet anyone with a known sulfosuccinate allergy should steer clear.
The ingredient is synthesized from plant-derived fatty alcohols and petrochemical ethylene oxide then neutralized with mineral salts, so it contains no animal material and is therefore appropriate for vegans and vegetarians.
No studies have shown any link between topical use and harm during pregnancy or breastfeeding. That said this is not medical advice and women who are pregnant or nursing should run any skincare product past a qualified health professional to be safe.
Disodium Laureth-12 Sulfosuccinate does not make skin more sensitive to sunlight and there are no special daytime precautions beyond normal sunscreen use.

Rating: 1 / 5
Disodium Laureth-12 Sulfosuccinate is highly water soluble and has a relatively large molecular size, so it tends to sit on the surface and rinse away without clogging pores. Its primary role is to lift off oil rather than add any, which keeps the likelihood of blocked pores very low. Because of this it is generally suitable for people who are prone to acne or breakouts.
Only leave-on products containing heavy emollients alongside this surfactant could potentially raise the risk of congestion, but in most rinse-off cleansers the ingredient poses minimal concern.
Summary
Disodium Laureth-12 Sulfosuccinate works as a gentle cleanser, foam booster and hydrotrope. It lowers water’s surface tension so oil and grime can wash away, builds a creamy lather that feels satisfying while you cleanse and helps dissolve other ingredients to keep formulas stable and clear.
This surfactant shows up often in sulfate-free shampoos, face washes and baby products because formulators appreciate its balance of cleaning power and mildness, though it still sits in the shadow of more widely known ingredients like SLS and cocamidopropyl betaine.
Overall safety data are reassuring with low rates of irritation or sensitization, and the ingredient is considered safe for regular use in rinse-off cosmetics. As with any new product it is smart to perform a quick patch test first to make sure your skin plays nicely with the full formula.
