# 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 an average of 6 ethylene oxide (EO) units.
## Chemical Properties and Structure
The molecular structure of C9-11 Pareth 6 consists of a hydrocarbon chain (C9-11) attached to a polyoxyethylene chain containing approximately 6 ethylene oxide units. This combination gives the molecule both hydrophobic (water-repelling) and hydrophilic (water-attracting) properties, making it an effective surfactant.
Key properties include:
– Molecular weight: Approximately 400-450 g/mol
– Appearance: Clear to slightly hazy liquid
– Solubility: Soluble in water and most organic solvents
– HLB value: Around 12-13 (moderate hydrophilicity)
## Industrial Applications

### Cleaning Products
C9-11 Pareth 6 is extensively used in:
– Dishwashing liquids
– Laundry detergents
– Hard surface cleaners
– Industrial degreasers
Its excellent wetting and emulsifying properties make it particularly effective in removing oily soils and greases.
### Personal Care Formulations
In cosmetic and personal care products, this surfactant serves as:
– Mild cleansing agent in shampoos and body washes
– Emulsifier in lotions and creams
– Foam booster in bubble baths
## Advantages Over Other Surfactants
Compared to similar ethoxylated alcohols, C9-11 Pareth 6 offers several benefits:
– Better balance between cleaning power and mildness
– Improved solubility in cold water formulations
– Lower irritation potential than higher EO variants
– Excellent compatibility with other surfactants
## Environmental and Safety Considerations
While generally considered safe for use in consumer products, proper handling is still essential:
– Biodegradability: Readily biodegradable under aerobic conditions
– Aquatic toxicity: Moderate; should be prevented from entering waterways in concentrated form
– Skin irritation: Low potential when properly formulated
– Eye irritation: Can cause mild irritation in concentrated forms
## Formulation Guidelines
When incorporating C9-11 Pareth 6 into products, consider:
– Typical use concentration: 1-15% depending on application
– pH stability: Stable in wide pH range (2-12)
– Temperature stability: Stable up to 50°C for prolonged periods
– Compatibility: Works well with anionic, nonionic, and amphoteric surfactants
## Future Outlook
As formulators seek more sustainable yet effective surfactants, C9-11 Pareth 6 continues to gain popularity due to its balanced performance profile. Ongoing research focuses on optimizing its production from renewable feedstocks and improving its environmental footprint without compromising functionality.
