    Product Description

    Decanoic Acid is a straight-chain fatty acid. While it is naturally found in milk and various plant oils, industrial production relies on the hydrolysis and fractionation of tropical oils.

    Key Features of our C10 Acid:

    1. High Purity: We strictly control the C8 (Caprylic) and C12 (Lauric) cuts to ensure the C10 content meets the stringent requirements for synthesizing downstream esters.
    2. Color Stability: Our product has a low APHA color value, making it excellent for cosmetic emollients and clear lubricants where color quality is paramount.
    3. Reactivity: It reacts readily with alcohols to form esters (Decanoates), which are widely used in flavors and fragrances.

    Applications

    1. Synthetic Lubricants & Greases:
      • Used to produce Polyol Esters (POEs) for aviation turbines and refrigeration compressor oils. C10 esters provide excellent thermal stability.
    2. Personal Care & Cosmetics:
      • A raw material for manufacturing esters used as emollients and emulsifiers.
    3. Flavors & Fragrances:
      • Ethyl Decanoate (formed from Decanoic Acid) is a key component in fruit flavors like grape and cognac.
    4. Agriculture:
      • Used in the formulation of eco-friendly herbicides and pesticides.
    5. Plasticizers:
      • Used in the synthesis of plasticizers for rubber and plastics.

    Storage Conditions (Critical)

    • Temperature Management: Decanoic Acid has a melting point near 31.5°C.
      • In Summer: It will likely be liquid.
      • In Winter: It will solidify into a hard white mass.
      • Heating: If melting is required, use a hot room or drum heating belt. Do not overheat (keep < 50°C) to prevent oxidation and darkening (yellowing).
    • Corrosion: It is a weak acid but can corrode carbon steel over time. We recommend storing in Stainless Steel (SS304/316) tanks or lined drums.
    • Ventilation: The product has a distinct, slightly rancid/sour fatty odor. Store in a well-ventilated area away from living quarters.

    Safety Precautions

    • Skin Irritation: Pure Decanoic Acid is a skin irritant. Direct contact can cause redness and burning. Always wear chemical-resistant gloves (Nitrile/Neoprene).
    • Eye Contact: Causes serious eye irritation. Safety goggles are mandatory during handling.
    • Inhalation: Inhalation of vapors or mist (if heated) can irritate the respiratory tract.
    • Leakage: If the liquid solidifies after a spill, scrape it up mechanically. If liquid, absorb with sand or earth.

    FAQ - Technical & Supply Chain

    • Q:

      How is CAS 334-48-5 utilized as a precursor in the production of industrial esters?

      A: Decanoic Acid (CAS 334-48-5) is typically applied in the esterification process with various alcohols to synthesize decyl esters, which serve as essential components in the formulation of high-stability synthetic lubricants and greases.
    • Q:

      Is this material intended for use in the manufacturing of industrial grease or metalworking fluids?

      A: Yes, this raw material is commonly used to produce metal soaps and greases due to its specific carbon chain length, which provides an optimal balance between oil solubility and structural thickening properties in industrial lubricant systems.
