# Ethoxylated C9-11 Alcohol with 6 EO Units: Properties and Applications
## 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 alcohol chain (a mixture of 9 to 11 carbon atoms) ethoxylated with an average of 6 ethylene oxide units. This structure gives the compound its unique amphiphilic nature:
The hydrophilic-lipophilic balance (HLB) of C9-11 Pareth 6 typically ranges between 12 and 13, making it suitable for various emulsification applications. It appears as a clear to slightly hazy liquid with mild characteristic odor, and is soluble in water, alcohols, and many organic solvents.
Key Physical Properties:
- Appearance: Clear to slightly hazy liquid
- Color: Colorless to pale yellow
- Odor: Mild characteristic
- Solubility: Water-soluble, forms clear solutions
- pH (1% solution): 5.0-7.0
- Cloud point (1% in water): ~50-60°C
## Industrial Applications
C9-11 Pareth 6 finds extensive use across multiple industries due to its excellent wetting, emulsifying, and detergent properties:
1. Household and Industrial Cleaning
This surfactant is commonly used in liquid detergents, all-purpose cleaners, and hard surface cleaners. Its ability to reduce surface tension makes it effective in removing grease and oil from various surfaces.
2. Personal Care Products
In cosmetics and personal care formulations, C9-11 Pareth 6 serves as an emulsifier, solubilizer, and mild cleansing agent. It’s found in shampoos, shower gels, and facial cleansers.
3. Textile Processing
The textile industry utilizes this compound as a wetting agent and detergent in various processing stages, including scouring, dyeing, and finishing.
4. Agricultural Formulations
As an adjuvant in pesticide formulations, C9-11 Pareth 6 helps improve the spreading and penetration of active ingredients on plant surfaces.
## Advantages Over Other Surfactants
C9-11 Pareth 6 offers several benefits compared to other surfactants in its class:
- Excellent wetting properties at low concentrations
- Good compatibility with other surfactants and formulation ingredients
- Relatively low foam generation compared to higher EO content ethoxylates
- Biodegradable under aerobic conditions
- Mild to skin at recommended use levels
