# Ethoxylated C9-11 Alcohol with 6 EO Units: A Versatile Surfactant
Keyword: C9-11 Pareth 6
## Introduction to C9-11 Pareth 6
C9-11 Pareth 6, chemically 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 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 alcohol chain (containing 9 to 11 carbon atoms) attached to a polyoxyethylene chain with an average of 6 ethylene oxide units. This balanced structure gives the compound several valuable characteristics:
– Hydrophilic-lipophilic balance (HLB) of approximately 12-13
– Good solubility in water
– Excellent wetting and emulsifying properties
– Low foam generation compared to higher EO content ethoxylates
– 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 typically occurs under controlled temperature and pressure conditions to ensure the desired degree of ethoxylation (6 EO units on average).
## Key Applications
