What Is Sodium Methyl Lauroyl Taurate?
Sodium Methyl Lauroyl Taurate is a mild, plant-derived surfactant created by combining lauric acid, a fatty acid most commonly obtained from coconut or palm kernel oil, with taurine, an amino acid already present in the human body. The resulting molecule, sodium 2-[methyl(1-oxododecyl)amino]ethanesulphonate, carries both water-loving and oil-loving parts, which makes it especially good at mixing oil, dirt and water so they can be rinsed away.
This ingredient was developed in the mid-20th century when formulators were searching for gentler alternatives to traditional sulfates. Because it is less irritating and better tolerated by sensitive skin, it quickly gained popularity in personal care labs around the world. Today it is made through a straightforward process: lauric acid is first reacted with methyl taurine to form lauroyl methyl taurate, which is then neutralized with sodium to create the final powdered or liquid form used in cosmetics.
You will find Sodium Methyl Lauroyl Taurate in a wide range of rinse-off and leave-on products such as facial cleansers, body washes, shampoos, bubble baths, micellar waters, cream or gel masks and even some sulfate-free toothpastes. Its ability to build rich yet gentle foam also makes it a favorite in kids’ washes and products marketed for reactive or mature skin.
Sodium Methyl Lauroyl Taurate’s Cosmetic Benefits/Uses
In formulations, Sodium Methyl Lauroyl Taurate serves more than one purpose, adding both performance and sensory appeal.
- Cleansing: Lifts away oil, sweat and environmental grime without stripping the skin’s natural moisture barrier, which helps leave skin feeling soft instead of tight
- Foaming: Produces a dense, creamy lather that improves spreadability and user experience, allowing the product to glide over skin or hair while aiding in even distribution of active ingredients
Who Can Use Sodium Methyl Lauroyl Taurate
This surfactant is gentle enough for most skin types, including sensitive, dry, oily and combination skin. Because it cleans without stripping the skin’s natural oils, it is often chosen for reactive or mature skin as well. There are no specific skin types that must avoid it, though anyone with a known allergy to coconut-derived ingredients should stay cautious.
Sodium Methyl Lauroyl Taurate is usually made from plant oils and a lab-synthesized form of taurine that does not come from animals, so products using it are typically suitable for vegans and vegetarians. Always check the full ingredient list to be sure the rest of the formula aligns with your preferences.
The ingredient is considered low risk for women who are pregnant or breastfeeding. Still, this is not medical advice and anyone who is expecting or nursing should review any skincare product with a healthcare professional to be safe.
It does not make skin more sensitive to sunlight, so it is not classed as photosensitizing. There are no known interactions with common actives such as retinoids, vitamin C or exfoliating acids, making it easy to slot into most routines.
Potential Side Effects/Adverse Reactions
Reactions to topical Sodium Methyl Lauroyl Taurate vary from person to person. The points below outline potential side effects, yet they are uncommon for the average user when the ingredient is used at normal levels in a well-formulated product.
- Mild redness or stinging, especially if applied to broken or freshly shaved skin
- Temporary eye irritation if the product accidentally gets into the eyes before rinsing

If any of these effects occur stop using the product and consult a healthcare professional for guidance.
Comedogenic Rating
Rating: 1 (out of 5)
Sodium Methyl Lauroyl Taurate is water soluble and designed to lift oils away from the skin then rinse off cleanly, so it has little chance to stay behind and block pores. Formulators also use it at low to moderate levels, further lowering any clogging risk. Because of these factors it earns a rating of 1, which is considered very low.
Suitable for acne-prone or breakout-prone skin.
No additional concerns are noted for this ingredient regarding pore clogging when it appears alongside commonly used emulsifiers or thickeners.
Summary
Sodium Methyl Lauroyl Taurate is mainly valued for two things: effective yet mild cleansing and lush foam creation. Its dual water-loving and oil-loving structure attaches to dirt and oil, suspends them in water and lets them wash away without stripping the skin or hair.
Thanks to these benefits it shows up in a growing number of sulfate-free cleansers, shampoos, body washes and kids’ products. While it is not as ubiquitous as traditional sulfates it is quickly gaining ground among brands that focus on gentleness and a pleasant sensory feel.
Overall safety is considered high, with irritation and pore clogging risks ranked low for most users. As with any new skincare ingredient it is smart to patch test a product containing Sodium Methyl Lauroyl Taurate before making it part of your daily routine, especially if your skin is sensitive.
