Ethoxylated C9-11 Alcohol with 6 EO Units

# Ethoxylated C9-11 Alcohol with 6 EO Units: A Versatile Surfactant

## Introduction to C9-11 Pareth 6

C9-11 Pareth 6, also known as Ethoxylated C9-11 Alcohol with 6 EO Units, is a nonionic surfactant widely used in various industrial and consumer applications. This chemical compound is created through the ethoxylation of C9-11 fatty alcohols with approximately 6 ethylene oxide (EO) units.

## Chemical Structure and Properties

The molecular structure of C9-11 Pareth 6 consists of a hydrocarbon chain (C9-11) with an ethoxylate chain containing an average of 6 ethylene oxide units. This structure gives the compound its amphiphilic nature, making it an effective surfactant.

Key properties include:

• Hydrophilic-Lipophilic Balance (HLB) value typically between 11-13

• Clear to slightly hazy liquid appearance

• Mild odor

• Good solubility in water and many organic solvents

## Manufacturing Process

The production of C9-11 Pareth 6 involves the controlled reaction of C9-11 fatty alcohols with ethylene oxide in the presence of a catalyst. The process requires careful monitoring to achieve the desired degree of ethoxylation (6 EO units).
