Description

4-Hexadecanol is a high-purity fatty alcohol, also known as cetyl alcohol, with the CAS registry number 19781-43-2. This compound serves as a versatile intermediate and functional additive, prized for its emollient, emulsifying, and thickening properties. It is an essential raw material for manufacturers in the personal care, cosmetics, pharmaceutical, and specialty chemical industries seeking reliable quality and consistent performance.

Application

• Cosmetics & Personal Care: A key emollient and opacifying agent in creams, lotions, ointments, and hair conditioners.
• Pharmaceuticals: Used as an emulsifier and stiffening agent in topical ointments, creams, and controlled-release formulations.
• Lubricants & Metalworking: Functions as a component in synthetic lubricants, greases, and metalworking fluid additives.
• Textile & Leather Processing: Acts as a softening agent, lubricant, and anti-static agent in fiber and leather treatment.
• Plastics & Polymers: Employed as a lubricant and release agent in polymer processing and as a raw material for plasticizer synthesis.
• Surfactant Synthesis: A fundamental building block for producing non-ionic surfactants like ethoxylates and sulfate esters.

Quality Control

Our 4-Hexadecanol is manufactured under a strict quality management system. Each batch is tested to ensure it meets high-purity standards, with specifications for identity, assay, and impurity profiles. A comprehensive Certificate of Analysis (COA) documenting purity, melting point, acid value, and hydroxyl value is provided with every shipment. We can supply grades compliant with relevant pharmacopeial (e.g., USP/NF, Ph. Eur.) or cosmetic standards upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent absorption of water vapor. Keep away from strong oxidizing agents.
