# 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 ethylene oxide (EO) units, is a nonionic surfactant widely used in various industrial and consumer applications. This chemical compound belongs to the family of alcohol ethoxylates, which are known for their excellent surface-active properties.
## Chemical Structure and Properties
The molecular structure of C9-11 Pareth 6 consists of:
– A C9-11 hydrocarbon chain (9 to 11 carbon atoms)
– A polyoxyethylene chain containing 6 ethylene oxide units
– A terminal hydroxyl group
This balanced structure gives the compound its unique properties:
– HLB value: Approximately 12-13 (moderate hydrophilicity)
– Appearance: Clear to slightly hazy liquid
– Solubility: Soluble in water and many organic solvents
– Biodegradability: Readily biodegradable under aerobic conditions
## Manufacturing Process
The production of C9-11 Pareth 6 involves the ethoxylation of C9-11 fatty alcohols with ethylene oxide in the presence of a catalyst. The reaction is carefully controlled to achieve the desired degree of ethoxylation (6 EO units per molecule).
