    Sodium Methyl Cocoyl Taurate CAS 12765-39-8

    Sodium Methyl Cocoyl Taurate (CAS 12765-39-8), commonly abbreviated as SMCT, is a premium amino acid-based anionic surfactant utilizing its taurine-derived structure to provide exceptional mildness and high-foaming capabilities in sulfate-free formulations. Chemically identified as the sodium salt of the coconut fatty acid amide of N-methyltaurine, this white paste or powder acts to create a dense, creamy lather that is stable even in the presence of sebum and hard water. As a gentle Amide surfactant derived from natural coconut oil and taurine (an amino acid type structure), it is extensively integrated into high-end facial cleansers, baby shampoos, and sensitive skin body washes to impart a soft, non-drying after-feel. We ensure bulk supply capabilities for this material, providing access to competitive factory pricing and customized specifications to meet specific active content forms (e.g., 35-40% Paste or 80%+ Powder/Granules). Full technical documentation, including MSDS, TDS, COA, is available to support compliance and safety protocols.

    Product Description

    Sodium Methyl Cocoyl Taurate is a high-performance mild surfactant. Unlike traditional surfactants, it maintains excellent foaming properties even in the presence of sebum and hard water.

    Key Features:

    1. Extreme Mildness: Low irritation to skin and eyes, making it suitable for sensitive skin and baby products.
    2. Rich Foam: Produces a stable, creamy, and elastic lather that feels luxurious during washing.
    3. Hard Water Tolerance: Does not form soap scum; maintains clarity and foaming power in hard water.
    4. Compatibility: Works well with other anionic, non-ionic, and amphoteric surfactants. It can help solubilize cationic polymers in shampoos (2-in-1 formulations).

    Physicochemical Properties

    The specifications below refer to the standard 35-40% Paste content commonly exported.

    ParameterSpecification (Standard)
    Appearance (25°C)White to off-white viscous paste
    Active Matter35.0% – 42.0% (Commonly ~38%)
    pH Value (10% Solution, 25°C)7.0 – 8.5
    Sodium Chloride (NaCl)4.0% – 7.0% (Standard Type)
    Free Fatty Acid≤ 2.0%
    Solid Content≥ 45.0%
    OdorCharacteristic, faint odor
    Color (Hazen/APHA)≤ 100
    StabilityStable at pH 5.0 – 9.0

    Note: Low-salt versions are also available upon request, but the standard paste typically contains the salt byproduct from synthesis.

    Applications

    1. Facial Cleansers:
      • The primary surfactant for cream-type facial cleansers (often combined with Sodium Cocoyl Glycinate). It provides the “squeaky clean” yet non-dry feeling.
    2. Sulfate-Free Shampoos:
      • Used as a primary or secondary surfactant to build viscosity and foam volume without sulfates.
    3. Body Washes:
      • For luxury, moisturizing body wash formulations.
    4. Baby Care Products:
      • Due to its low irritation profile.
    5. Shaving Creams:
      • Helps create a dense foam structure.

    For related mild anionic surfactants used in cleansing systems, see Sodium Lauroyl Isethionate and Sodium Lauroyl Sarcosinate.

    Storage Conditions

    • Temperature: Store in a cool, dry place between 10°C and 35°C.
    • Phase Change: As a paste, it may solidify or become thicker at lower temperatures. This is reversible; warm gently to restore consistency before use.
    • Packaging: Keep the drum tightly closed to prevent contamination and water loss.
    • Shelf Life: 24 months in original unopened packaging.

    Safety Precautions

    • Handling: Although it is a mild surfactant, direct contact with the concentrated paste in the eyes may cause irritation.
    • PPE: Wear safety goggles and gloves when handling bulk drums.
    • First Aid:
      • Eye Contact: Flush with plenty of water immediately.
      • Skin Contact: Rinse with water.
    • Biodegradability: The product is readily biodegradable and environmentally friendly.

    FAQ - Technical & Supply Chain

    • Q:

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

      A: 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.
    • Q:

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

      A: 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.
    • Q:

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

      A: 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.
    • Q:

      Is Sodium Methyl Cocoyl Taurate compatible with cationic conditioning agents?

      A: 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.
    • Q:

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

      A: 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.
