What Is Sodium Methyl Myristoyl Taurate?
Sodium Methyl Myristoyl Taurate is a mild cleansing agent made by joining a fatty acid from coconut or palm oil with taurine, a naturally occurring amino acid often found in our own bodies. The finished ingredient is classed as a surfactant, meaning it helps water mix with oil and dirt so they can be rinsed away.
The idea of pairing fatty acids with taurine was explored in the mid-20th century when chemists searched for skin-friendlier alternatives to harsh soaps. Over time the process was refined to give us Sodium Methyl Myristoyl Taurate, which gained popularity as consumers asked for sulfate-free and low-irritation cleansers.
Manufacturing starts with myristic acid, a 14-carbon fatty acid usually sourced from coconut or palm. The acid is turned into an acyl chloride, reacted with methyl taurine then neutralized with sodium to form the final salt. This recipe produces a powder or paste that dissolves easily in water and keeps its mild character.
You will spot Sodium Methyl Myristoyl Taurate in face washes, body washes, shampoo, foaming cleansers, bubble baths and even some toothpaste. It is also added to gentle baby products and micellar waters where a creamy, cushiony lather is desired without stripping the skin.
Sodium Methyl Myristoyl Taurate’s Cosmetic Benefits/Uses
This ingredient earns its place on labels by improving how a product cleans and feels.
- Cleansing: Lifts away oil, makeup and daily grime so they can be rinsed off with water leaving skin and hair fresh
- Foaming: Creates a rich stable lather that makes washing more pleasant and helps spread the formula evenly

Who Can Use Sodium Methyl Myristoyl Taurate
This surfactant is considered gentle enough for nearly all skin types, including dry, oily, combination and sensitive complexions. It rinses away without leaving a film so it suits acne-prone skin as well. The main group that should steer clear are people who know they are allergic to taurates or to any other part of the finished formula, as an allergy could trigger redness or itching.
Sodium Methyl Myristoyl Taurate is usually made from coconut or palm oil and laboratory-made taurine, not from animal sources, so it is generally viewed as suitable for vegans and vegetarians. If a brand claims cruelty-free status it is still wise to double-check their certification.
Current safety data show no special risks for pregnant or breastfeeding women when the ingredient is used in rinse-off products at normal levels. This is not medical advice and anyone who is expecting or nursing should ask a doctor before starting any new skincare just to be safe.
The ingredient does not make skin more sensitive to sunlight and there are no known interactions with common actives like retinol or vitamin C. Its mild nature has even made it popular in baby cleansers and sensitive-scalp shampoos.
Potential Side Effects/Adverse Reactions
Reactions to Sodium Methyl Myristoyl Taurate differ from person to person. The points below list possible but uncommon effects. When the ingredient is used correctly most people will not notice any problems.
- Mild stinging if the raw ingredient gets into the eyes before being diluted in a finished product
- Temporary dryness or tightness when used at very high levels or in very hot water
- Redness or itching in people who have a specific allergy to taurates or other surfactants in the formula
- Rare cases of contact dermatitis if the skin barrier is already compromised
If you experience any of these issues stop using the product and seek advice from a healthcare professional or pharmacist.
Comedogenic Rating
Rating: 0 out of 5. Sodium Methyl Myristoyl Taurate is water soluble and used in rinse-off formulas so it does not stay on the skin or clog pores. Its molecules are too large to lodge inside follicles and any residue is easily washed away.
Because of this low rating it is generally considered suitable for people who are prone to acne or breakouts.
If a cleanser also contains heavy oils or waxes the overall product could still feel greasy but that would not be due to Sodium Methyl Myristoyl Taurate itself.
Summary
Sodium Methyl Myristoyl Taurate is a mild surfactant that lifts oil and dirt from the skin then rinses away while creating a cushiony foam that makes washing feel pleasant. Its gentle character limits dryness that harsher sulfates can cause.
The ingredient has gained popularity with the rise of sulfate-free shampoos, facial cleansers and baby washes although it is not as common as older surfactants because it costs more to make.
Safety assessments show a very low risk of irritation or pore clogging at typical use levels and its plant-based origin suits vegan routines. Still, patch test any new product containing this ingredient to be sure your skin agrees with the full formula.
