n-Octanol Plasticizer

Updated: 2026-08-04

Overview

n-Octanol plasticizer is a versatile chemical additive derived from n-octanol (caprylic alcohol). It is widely used to improve the flexibility, durability, and processing characteristics of polymers such as PVC and rubber. Due to its low volatility and high compatibility with various materials, it is a preferred choice in industrial applications. Unlike phthalate-based plasticizers, n-octanol plasticizer offers a more environmentally friendly alternative with lower toxicity concerns. It is commonly utilized in products requiring long-term stability, such as cables, flooring, and automotive components.

Physical and Chemical Properties

n-Octanol plasticizer is a colorless to pale yellow liquid with a mild odor. It has a relatively high boiling point (195°C) and low melting point (-16°C), making it suitable for high-temperature processing. Its density of 0.83 g/cm³ ensures easy blending with polymer matrices. The compound is slightly soluble in water but miscible with most organic solvents, including alcohols, ethers, and ketones. This property enhances its effectiveness as a plasticizer in diverse formulations. Its low volatility contributes to the longevity of plasticized products, reducing the need for frequent replacements.

Main Applications

The primary use of n-octanol plasticizer is in the production of flexible PVC products, such as cables, hoses, and flooring. It imparts elasticity and resistance to cracking, extending the lifespan of these materials. In rubber manufacturing, it improves workability and reduces brittleness. Additionally, it is employed in coatings and adhesives to enhance adhesion and film formation. Its compatibility with other polymers makes it a versatile additive in automotive, construction, and consumer goods industries. Specialty applications include medical devices and food packaging, where non-toxicity is critical.

Safety and Storage

While n-octanol plasticizer is less toxic than phthalate alternatives, proper handling is essential. Avoid inhalation, skin contact, and ingestion by using gloves, goggles, and respirators in poorly ventilated areas. In case of exposure, rinse thoroughly with water and seek medical advice if symptoms persist. Store the plasticizer in a cool, dry place away from direct sunlight and ignition sources. Use corrosion-resistant containers to prevent contamination. Always follow local regulations for chemical storage and disposal to minimize environmental impact.

B2B Procurement Guide

When sourcing n-octanol plasticizer, prioritize suppliers with certifications such as ISO or REACH compliance. Request technical data sheets (TDS) to verify purity, CAS number, and test methods. Bulk purchases (drums or tankers) often offer cost savings but require proper storage facilities. Consider the plasticizer's compatibility with your polymer matrix and processing conditions. Sampling is recommended to evaluate performance before large-scale procurement. Prices vary based on quantity, purity, and supplier location, with average ranges between $2.50-$4.00 per kilogram.
