Overview
Hexylresorcinol is an organic compound derived from resorcinol, featuring a hexyl group attached to the benzene ring. It is widely recognized for its antiseptic and anesthetic properties, making it a key ingredient in medical and personal care products. Its efficacy against bacteria and fungi has led to its use in throat lozenges, skin treatments, and oral hygiene solutions. First synthesized in the early 20th century, hexylresorcinol has since become a staple in pharmaceutical formulations. Its dual functionality as both an antimicrobial and local anesthetic agent distinguishes it from similar compounds. The compound is typically synthesized through alkylation of resorcinol, ensuring high purity for industrial and medical applications.
Physical and Chemical Properties
Hexylresorcinol appears as a white to pale yellow crystalline powder with a faint phenolic odor. It has a melting point range of 62-67°C and a boiling point of 333-335°C. The compound is soluble in organic solvents like ethanol, ether, and chloroform but exhibits limited solubility in water. Its molecular structure includes a hydroxyl group at positions 1 and 3 on the benzene ring, contributing to its antiseptic properties. The hexyl side chain enhances lipid solubility, improving its penetration into microbial cell membranes. These properties make hexylresorcinol effective against a broad spectrum of pathogens, including Gram-positive bacteria and fungi.
Main Applications
Hexylresorcinol is primarily used in the pharmaceutical and personal care industries. In throat lozenges, it acts as a local anesthetic and antiseptic, providing relief from sore throats and infections. It is also incorporated into skin antiseptics and wound cleansers due to its ability to reduce microbial load. In oral care, hexylresorcinol is found in mouthwashes and toothpaste for its plaque-inhibiting effects. Beyond healthcare, it serves as a preservative in cosmetics and a deworming agent in veterinary medicine. Its versatility and safety profile make it a preferred choice for formulations requiring dual antiseptic and anesthetic action.
Safety and Storage
Hexylresorcinol should be handled with care to avoid skin and eye irritation. Prolonged exposure may cause sensitization, necessitating the use of protective gloves and goggles. Storage conditions should prioritize cool, dry environments away from direct sunlight to prevent degradation. In industrial settings, proper ventilation is essential to minimize inhalation risks. The compound is stable under recommended storage conditions but may decompose if exposed to excessive heat or moisture. Disposal should comply with local regulations to prevent environmental contamination.
B2B Procurement Guide
When procuring hexylresorcinol, prioritize suppliers with certified manufacturing practices (e.g., GMP, ISO). Verify the CAS number (136-77-6) and request certificates of analysis to confirm purity (typically 98-99%). Bulk purchases may qualify for discounts, but ensure the supplier can meet consistent quality standards. Consider logistical factors such as packaging (sealed, moisture-proof containers) and lead times. For international shipments, confirm compliance with regional regulatory requirements. Establish long-term relationships with reliable suppliers to secure stable pricing and availability.
