Overview
1-Hexadecanol, commonly known as cetyl alcohol, is a long-chain fatty alcohol derived from natural sources like palm oil or synthesized from petroleum. It is widely used in personal care products, pharmaceuticals, and industrial applications due to its emollient and thickening properties. As a non-ionic surfactant, 1-hexadecanol is valued for its ability to stabilize emulsions and improve texture in formulations. It is a key ingredient in creams, lotions, and ointments, where it enhances viscosity and provides a smooth feel.
Physical and Chemical Properties
1-Hexadecanol is a white, waxy solid at room temperature with a mild, characteristic odor. It has a melting point of 49-52°C and a boiling point of 344°C. Its density is approximately 0.811 g/cm³, and it is insoluble in water but soluble in organic solvents like ethanol and ether. The compound is chemically stable under normal conditions but may degrade when exposed to strong oxidizing agents. Its low volatility and high melting point make it suitable for applications requiring stability at elevated temperatures.
Main Applications
In the cosmetics industry, 1-hexadecanol is used as an emollient and thickening agent in products like moisturizers, hair conditioners, and lipsticks. It helps improve texture and provides a smooth, creamy consistency. Pharmaceutical formulations utilize cetyl alcohol as an excipient in ointments and creams, where it acts as a stabilizer and emulsifier. Industrial applications include its use in lubricants, plasticizers, and surfactants for manufacturing processes.
Safety and Storage
1-Hexadecanol is generally regarded as safe for use in cosmetics and pharmaceuticals. However, prolonged exposure to dust may cause mild skin or eye irritation. Proper personal protective equipment (PPE) like gloves and goggles is recommended during handling. Storage should be in a cool, dry place away from direct sunlight and heat sources to prevent degradation. Containers should be tightly sealed to avoid contamination and moisture absorption.
B2B Procurement Guide
When procuring 1-hexadecanol, buyers should verify the purity grade (e.g., USP, NF, or technical grade) based on intended use. Pharmaceutical and cosmetic applications often require higher purity levels (≥98%). Reliable suppliers should provide certificates of analysis (CoA) and comply with industry standards like ISO or GMP. Bulk purchases may offer cost advantages, but storage capacity and shelf life should be considered. Prices vary depending on quantity and supplier, typically ranging from $5 to $15 per kg.
