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 hydrophobic tail (C9-11 alkyl chain)
– A hydrophilic head (6 ethylene oxide units)

This balanced structure gives the compound its excellent surfactant properties:

– HLB value typically between 11-13
– Good solubility in water
– Effective wetting and emulsifying capabilities
– Mild to skin compared to harsher surfactants

## Key Applications

### 1. Cleaning Products

C9-11 Pareth 6 is commonly found in:

– Dishwashing liquids
– Hard surface cleaners
– Laundry detergents
– Industrial cleaners

### 2. Personal Care Formulations

Due to its mild nature, it’s used in:

– Shampoos
– Body washes
– Facial cleansers
– Shaving products

### 3. Industrial Applications

– Textile processing
– Agricultural formulations
– Paint and coating additives
– Metal working fluids

## Advantages Over Other Surfactants

Compared to similar ethoxylated alcohols, C9-11 Pareth 6 offers:

– Better foam characteristics than lower EO variants
– Improved solubility compared to higher molecular weight surfactants
– Excellent compatibility with other formulation ingredients
– Biodegradability under appropriate conditions

## Safety and Environmental Considerations

While generally considered safe for many applications, proper handling is still essential:

– Use appropriate personal protective equipment when handling concentrated forms
