    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.

    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:

      How does Sodium Methyl Cocoyl Taurate CAS 12765-39-8 compare to traditional sulfates like SLS?

      A: Unlike Sodium Lauryl Sulfate (SLS), Sodium Methyl Cocoyl Taurate (CAS 12765-39-8) is an amino acid-type surfactant that is significantly milder on the skin and eyes, non-stripping, and biodegradable, making it the preferred choice for "sulfate-free" and sensitive skin applications.
    • Q:

      Is this surfactant compatible with cationic conditioning agents?

      A: Yes, despite being anionic, its amide structure makes it compatible with many cationic polymers and amphoteric surfactants, allowing for the formulation of conditioning shampoos (2-in-1 products) without precipitation.
