Sodium Laureth Sulfate (SLES) is commonly found at a 70% concentration. This specific concentration is often associated with a pH range of 6.5-8.5.
Understanding Sodium Laureth Sulfate (SLES)
Sodium Laureth Sulfate is a widely used chemical compound known for its effective cleaning properties. It functions primarily as a surfactant, meaning it reduces the surface tension of liquids, allowing for better wetting and emulsification of oils and dirt.
Key Characteristics and Properties
SLES is an anionic surfactant, highly valued in various product formulations due to its ability to create lather and effectively remove grease and grime. Its dual nature, possessing both hydrophilic (water-attracting) and hydrophobic (water-repelling) properties, makes it particularly beneficial in detergents and cleaning agents.
- Hydrophilic End: Attracted to water, helping to lift dirt and oils into the water.
- Hydrophobic End: Attracted to oils and greases, surrounding them and breaking them down.
This unique combination allows SLES to encapsulate dirt particles, preventing them from redepositing on surfaces and making them easier to rinse away.
Applications of Sodium Laureth Sulfate
Given its powerful cleaning and foaming capabilities, SLES is a staple ingredient in numerous consumer products.
- Detergents: It is a key component in many laundry detergents, dishwashing liquids, and all-purpose cleaners, where its surfactant properties ensure efficient cleaning.
- Personal Care Products: Frequently found in shampoos, body washes, and liquid hand soaps to create a rich lather and effectively cleanse the skin and hair.
Summary of SLES Properties
To provide a clear overview, here's a summary of key attributes related to Sodium Laureth Sulfate:
| Property | Detail |
|---|---|
| Common Concentration | 70% |
| Typical pH Range | 6.5 - 8.5 (at 70% concentration) |
| Primary Function | Surfactant (reducing surface tension, aiding in cleaning) |
| Key Properties | Hydrophilic and Hydrophobic (effective in lifting and removing dirt and oils) |
| Common Uses | Detergents, shampoos, body washes, dish soaps |
This specific concentration of 70% allows formulators to dilute it to appropriate levels for different applications, balancing cleaning efficacy with product stability and user experience.
