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 household 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) attached to a polyoxyethylene chain containing about 6 ethylene oxide units. This combination gives the molecule both hydrophobic and hydrophilic properties, making it an effective surfactant.

Key properties include:

• HLB value typically between 12-14

• Good emulsifying and wetting capabilities

• Low foam generation

• Excellent compatibility with other surfactants

## Industrial Applications

### Cleaning Products

C9-11 Pareth 6 is commonly found in various cleaning formulations due to its excellent degreasing properties and moderate foaming characteristics. It’s particularly useful in:

• Industrial and institutional cleaners

• Hard surface cleaners

• Degreasers

• Laundry detergents

### Personal Care Formulations

In cosmetic and personal care products, this surfactant serves as:

• A mild cleansing agent in shampoos and body washes

• An emulsifier in creams and lotions

• A solubilizer for fragrances and essential oils

## Advantages Over Other Surfactants

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

• Better biodegradability than higher EO variants

• Lower irritation potential than sulfated surfactants

• More stable performance across a wide pH range

• Excellent cold water solubility

## Safety and Environmental Considerations

While generally considered safe for most applications, proper handling procedures should be followed:

• Avoid prolonged skin contact

• Use appropriate personal protective equipment when handling concentrated forms

• Follow local regulations for disposal

The compound is readily biodegradable under aerobic conditions, making it an environmentally preferable choice compared to some other surfactants.

## Conclusion

Ethoxylated C9-11 Alcohol with 6 EO Units represents an important class of nonionic surfactants that balance performance with environmental considerations. Its versatility across multiple industries ensures continued demand for this effective surface-active agent.
