Factory supply 1-Hexadecanol Cas36653-82-4 with favorable price

Details:

1-Hexadecanol, also known as cetyl alcohol or *n*-hexadecan-1-ol, is a long-chain fatty alcohol with the following characteristics:

Chemical Structure

Formula: C??H??O

Structure: A straight-chain, 16-carbon aliphatic alcohol with a hydroxyl (-OH) group at the terminal (1st) carbon.

Molecular Weight: 242.44 g/mol.

Physical Properties

Appearance: White, waxy solid or flakes with a mild characteristic odor.

Melting Point: ~49–50°C.

Boiling Point: ~344°C.

• Solubility:

  • Insoluble in water.

  • Soluble in ethanol, ether, chloroform, and other organic solvents.

• Hydrophilic-Lipophilic Balance (HLB): ~15.5 (acts as a non-ionic surfactant).

Applications

1. Cosmetics & Personal Care:

   • Emollient: Softens skin and hair in creams, lotions, and conditioners.

   • Thickener/Stabilizer: Creates viscosity and stabilizes emulsions (e.g., prevents separation in lotions).

   • Opacifying Agent: Gives products a pearlescent or opaque appearance.

2. Pharmaceuticals:

   • Used in ointments, suppositories, and topical formulations as a stiffening agent.

3. Industrial Uses:

   • Lubricants: Acts as a lubricant in metalworking or textile processing.

   • Surfactant Production: Raw material for synthesizing detergents or emulsifiers.

   • Biodegradable Polymers: Precursor for eco-friendly plastics.

Synthesis

Natural Sources: Derived via hydrogenation of fatty acids (e.g., palmitic acid from palm or coconut oil).

Synthetic Routes: Produced through the Ziegler process (ethylene growth followed by oxidation/hydrolysis).

Safety & Regulation

Toxicity: Low toxicity; generally recognized as safe (GRAS) for topical use.

Skin Irritation: May cause mild irritation in sensitive individuals.

Regulatory Status: Approved by the FDA, EU Cosmetics Regulation, and other agencies for use in cosmetics and pharmaceuticals.

Biodegradability: Readily biodegradable under environmental conditions.

Key Advantages

Non-greasy texture enhancer.

Enhances shelf life of formulations by stabilizing emulsions.

Biocompatible and derived from renewable sources (when plant-based).

Cetyl alcohol is a versatile ingredient critical to the texture and stability of many consumer and industrial products.
