What is Sodium Methyl Cocoyl Taurate CAS 12765-39-8?

Sodium Methyl Cocoyl Taurate CAS 12765-39-8 is an amino acid-type anionic surfactant produced from coconut fatty acid amide of N-methyltaurine. It is commonly supplied as a white to off-white viscous paste and is used in sulfate-free shampoos, facial cleansers, body washes, baby care, and other mild cleansing products.

How does Sodium Methyl Cocoyl Taurate compare with SLS or SLES?

It is generally much milder and lower-irritating than SLS and SLES while still producing rich, stable foam. This makes it suitable for sensitive-skin, baby-care, and sulfate-free formulations where strong petroleum-based sulfates are being replaced.

Does Sodium Methyl Cocoyl Taurate still foam in hard water or oily conditions?

Yes. It keeps its lather in the presence of calcium, magnesium, and sebum, and it does not form the traditional soap scum associated with ordinary soap. This helps maintain cleansing performance in hard-water areas and in shampoo or facial-cleanser use.

Is Sodium Methyl Cocoyl Taurate compatible with cationic conditioning agents?

Yes, despite being an anionic surfactant, its amide structure allows useful compatibility with many cationic polymers and amphoterics. It can therefore be used in 2-in-1 conditioning shampoos and mild rinse-off systems when the formulation is balanced correctly.

What are typical specifications for the 35-42% active cosmetic paste grade?

The standard paste grade is normally white to off-white and viscous, with active matter around 35.0-42.0%, pH 7.0-8.5 on a 10% solution, sodium chloride about 4.0-7.0%, free fatty acid not more than 2.0%, and solid content not less than 45.0%. It is generally stable in pH 5.0-9.0 systems; low-salt versions may also be available.

Product Description

Sodium Methyl Cocoyl Taurate, CAS 12765-39-8, also called SMCT, is an amino acid-type anionic surfactant made from the coconut fatty acid amide of N-methyltaurine.

Synonyms: SMCT; Sodium N-cocoyl-N-methyltaurate; Sodium methyl cocoyl tauride; Sodium N-methyl-N-cocoyl taurate; Amides coco N-methyl-N-(2-sulfoethyl) sodium salts.

CAS: 12765-39-8.

It is supplied as a white to off-white viscous paste.

It has an active matter of 35.0–42.0% for the standard cosmetic paste grade.

It is much milder and lower-irritating than SLS or SLES while producing rich, stable foam.

It keeps its lather in hard water and oily conditions and does not form soap scum.

Its amide structure allows compatibility with many cationic polymers and amphoterics.

It is used as the primary surfactant in sulfate-free shampoos and facial cleansers.

It builds viscosity and foam volume without sulfates.

It is used in body washes for a mild, moisturizing cleanse.

It is suitable for baby care products because of its low irritation.

It helps create a dense foam structure in shaving creams.

It is compatible with other anionic, non-ionic and amphoteric surfactants.

Confirm appearance, active matter, pH, sodium chloride, free fatty acid, solid content, odor and color.

Store in a cool, dry place between 10°C and 35°C; the paste may thicken or solidify at lower temperatures.

Confirm packaging with the requested quantity and destination requirements.
