# Ethoxylated C9-11 Alcohol with 6 EO Units: Properties and Applications

## 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 characteristic properties:

– Hydrophilic-lipophilic balance (HLB) of approximately 12-13
– Clear to slightly hazy liquid appearance at room temperature
– Mild characteristic odor
– Soluble in water and most organic solvents
– Good wetting and emulsifying properties

## Manufacturing Process

The production of C9-11 Pareth 6 involves the following steps:

– Selection of C9-11 fatty alcohol feedstock
– Purification of the alcohol mixture
