Thymol[2]

Updated: 2026-09-12

Overview

Thymol is a naturally occurring phenolic compound derived from the essential oils of thyme (Thymus vulgaris) and other plants. It is a monoterpene with a distinct aromatic odor and is widely recognized for its antimicrobial and antifungal properties. Thymol is commonly used in the food, pharmaceutical, and cosmetic industries due to its ability to act as a preservative and flavoring agent. As a B2B chemical, thymol is valued for its versatility and efficacy. It is often sourced in bulk for industrial applications, where its purity and stability are critical. The compound’s natural origin also makes it a preferred choice for eco-friendly and sustainable product formulations.

Physical and Chemical Properties

Thymol is a white crystalline solid with a melting point of 49-51 °C and a boiling point of 232-233 °C. It has a density of 0.96 g/cm³ and is slightly soluble in water but highly soluble in organic solvents like ethanol and ether. Its molecular formula is C10H14O, and it has a molecular weight of 150.22 g/mol. The compound exhibits strong antimicrobial and antifungal properties, making it effective in inhibiting the growth of bacteria and fungi. Its aromatic nature also contributes to its use as a fragrance in various products. Thymol is stable under normal storage conditions but should be protected from light and oxidizing agents to maintain its efficacy.

Main Applications

Thymol is extensively used in the food industry as a preservative and flavoring agent, particularly in meat and dairy products. Its antimicrobial properties help extend shelf life and prevent spoilage. In the pharmaceutical industry, thymol is incorporated into antiseptics, mouthwashes, and throat lozenges for its germicidal effects. In cosmetics, thymol is used as a fragrance component and preservative in products like soaps, lotions, and perfumes. It is also employed in agricultural applications as a pesticide and fungicide. The compound’s versatility and natural origin make it a popular choice across multiple industries.

Safety and Storage

Thymol should be handled with care as it may cause skin and eye irritation upon contact. Proper personal protective equipment (PPE), such as gloves and goggles, is recommended when working with the compound. In case of exposure, rinse thoroughly with water and seek medical advice if necessary. Storage conditions for thymol include keeping it in a cool, dry place away from direct sunlight and oxidizing agents. The compound should be stored in airtight containers to prevent degradation. Proper labeling and segregation from incompatible materials are essential to ensure safety and maintain product integrity.

B2B Procurement Guide

When procuring thymol for industrial use, it is crucial to verify the purity and CAS number (89-83-8) to ensure quality. Suppliers should provide certificates of analysis (CoA) to confirm the product’s specifications. Bulk purchasing is often cost-effective, but buyers should consider storage capacity and shelf life to avoid waste. Procurement professionals should also evaluate suppliers based on reliability, consistency, and compliance with industry standards. Establishing long-term partnerships with reputable suppliers can ensure a steady supply of high-quality thymol. Additionally, buyers should stay informed about market trends and price fluctuations to make informed purchasing decisions.
