Basic Information
Product Name: Octadecyl Methacrylate
Molecular Formula: C22H42O2
Molecular Weight: 338.57 g/mol
CAS Number: 32360-05-7
Physical and Chemical Properties
Appearance: Colorless to light yellow oily liquid or waxy solid (may solidify at low temperatures); odorless or with a faint characteristic smell.
Physical Parameters:
Melting Point: 18-22°C
Boiling Point: 215°C (at 10 mmHg); decomposes at high temperatures under atmospheric pressure
Density: 0.86 g/cm³ (25°C)
Solubility: Insoluble in water; soluble in organic solvents (e.g., ethanol, ethyl ether, acetone, benzene).
Chemical Properties:
Contains a reactive methacrylate double bond, enabling polymerization (e.g., forming poly(octadecyl methacrylate), a hydrophobic polymer).
Reacts with initiators (e.g., peroxides) to undergo free-radical polymerization or copolymerization with other monomers (e.g., methyl methacrylate, styrene).
Primary Applications
(1) Cosmetics and Personal Care
Film-Forming Agent and Emollient:
Used in hairsprays, gels, and lotions to form flexible, water-resistant films on skin/hair.
Imparts softness and smoothness in creams, lipsticks, and mascaras; improves product texture and spreadability.
UV Filter Additive:
Copolymerized with UV-absorbing monomers to enhance the compatibility of sunscreen agents in oil-based formulations.
(2) Pharmaceuticals
Controlled-Release Coatings:
Forms hydrophobic polymer coatings for tablets/capsules to regulate drug release rates.
Dermatological Formulations:
Used in topical creams as an emollient or film former for wound dressings.
(3) Industrial and Polymer Materials
Plastic Additives:
Acts as a modifier in acrylic resins, PVC, and polyethylene to improve flexibility, impact resistance, and surface gloss.
Textile and Leather Industry:
Imparts water repellency and softness to fabrics/leather as a finishing agent.
Adhesives and Coatings:
Used in pressure-sensitive adhesives and architectural paints to enhance adhesion and weather resistance.
(4) Other Applications
Lubricants: As a component in synthetic lubricating oils and greases.
Agriculture: In formulations for slow-release fertilizers or pesticide carriers.
Safety and Handling
Toxicity: Low toxicity (oral LD50 in rats: >5 g/kg); may cause mild skin/eye irritation upon direct contact.
Hazard Notes: Combustible; avoid high heat and strong oxidizers.
Storage: Store in a cool, dry, well-ventilated area, sealed in airtight containers. Keep away from light and sources of ignition.
Regulatory Compliance:
Cosmetic applications must meet EU REACH, US FDA, and China NMPA standards.
Industrial grades follow ISO or regional quality specifications (e.g., ASTM).
