# 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 a C9-11 fatty alcohol with 6 units of ethylene oxide (EO).
## Chemical Properties and Structure
The molecular structure of C9-11 Pareth 6 consists of:
– A hydrophobic tail (C9-11 alcohol)
– A hydrophilic head (6 EO units)
This amphiphilic nature gives the compound its excellent surfactant properties, allowing it to reduce surface tension between liquids or between a liquid and a solid.
## Key Characteristics
Some important properties of C9-11 Pareth 6 include:
– 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
## Industrial Applications
### 1. Cleaning Products
C9-11 Pareth 6 is commonly used in:
– Dishwashing liquids
– Hard surface cleaners
– Industrial degreasers
– Laundry detergents
### 2. Personal Care
In cosmetic formulations, it serves as:
– Emulsifier in creams and lotions
– Foam booster in shampoos
– Solubilizer for fragrances
### 3. Industrial Processes
Other applications include:
– Textile processing
– Metal working fluids
– Agricultural formulations
– Paint and coating additives
## Advantages Over Other Surfactants
Compared to similar surfactants, C9-11 Pareth 6 offers:
– Better mildness than higher EO content ethoxylates
– Improved solubility compared to lower EO content versions
– Excellent wetting and emulsifying properties
– Good compatibility with other formulation ingredients
## Safety and Environmental Considerations
While generally considered safe for most applications, proper handling is still important:
– Wear appropriate PPE when handling concentrated forms
– Avoid direct eye contact
– Store in well-ventilated areas
