Sodium Lauryl Ether Sulfate (SLES 70%)
Product Description
Sodium Lauryl Ether Sulfate (SLES) is a widely used anionic surfactant commonly found in personal care, household cleaning, and industrial cleaning products.
SLES 70% is normally supplied as a viscous clear to pale yellow gel or paste containing approximately 70% active surfactant matter.
It is well known for its excellent foaming, cleansing performance, compatibility with other surfactants, and relatively mild cleansing action compared with Sodium Lauryl Sulfate (SLS).
Key Benefits
Excellent foaming performance
Strong cleansing and degreasing ability
Produces rich and stable foam
Good compatibility with other surfactants
Easier to formulate than many strong anionic surfactants
Can be thickened using sodium chloride (salt)
More mild than SLS in many formulations
Cost-effective primary surfactant
Suitable for personal care and household cleaning products
Common Applications
SLES 70% is commonly used in:
Shampoo
Body wash
Shower gel
Hand wash
Facial cleansers
Liquid soap
Dishwashing liquid
Car wash shampoo
Laundry liquid
Household cleaners
General-purpose cleaning products
Typical Usage Rate
Product Type
Typical SLES 70% Usage Rate
Shampoo
10–35%
Body Wash / Shower Gel
8–25%
Hand Wash
5–20%
Facial Cleanser
3–15%
Dishwashing Liquid
15–40%
Car Wash Shampoo
5–20%
Laundry Liquid
5–25%
Note: The exact percentage depends on the desired cleansing strength, foam level, mildness, viscosity, and total surfactant system.
Active Matter Calculation
SLES 70% contains approximately 70% active surfactant.
For example:
10% SLES 70% × 0.70 = approximately 7% active surfactant matter
This calculation is useful when designing formulas based on the total active surfactant concentration.
Main Functions
1. High Foam Production
SLES produces rich, dense, and stable foam, making it suitable for shampoos, body washes, hand washes, and cleaning products.
2. Excellent Cleansing
It effectively helps remove:
Oil
Dirt
Grease
Sebum
Product buildup
General surface contamination
3. Milder Than SLS
Because SLES is ethoxylated, it is generally considered less harsh than Sodium Lauryl Sulfate (SLS), although irritation can still occur at high concentrations.
4. Easy Thickening
SLES-based formulations can often be thickened using sodium chloride (NaCl), especially when combined with amphoteric surfactants such as Cocamidopropyl Betaine.
5. Cost Effective
SLES provides strong cleansing and foaming performance at a relatively economical cost, making it suitable for both personal-care and large-volume cleaning formulations.
6. Good Compatibility
SLES works well with ingredients such as:
Cocamidopropyl Betaine (CAPB)
Nonionic surfactants
Amphoteric surfactants
Foam boosters
Thickeners
Conditioning ingredients
Fragrances
Preservatives
Common Shampoo Surfactant System
A simple shampoo formulation may contain:
Ingredient
Function
SLES 70%
Primary cleanser and foaming agent
Cocamidopropyl Betaine
Improves mildness and foam stability
Sodium Chloride
Viscosity / thickness adjustment
Preservative
Protects against microbial growth
Fragrance
Provides scent
Water
Main carrier / solvent
Recommended pH
A commonly used finished-product pH range is approximately:
pH 5.5–7.5
The final pH should always be selected according to the complete formulation and intended application.
Important Considerations
Although SLES is generally milder than SLS, excessive concentrations or poorly balanced formulations may cause:
Skin dryness
Scalp irritation
Eye irritation
Increased sensitivity in some users
Using SLES together with milder amphoteric surfactants such as CAPB can help improve the mildness of the finished product.
Storage
Store SLES 70%:
In a cool, dry place
In a tightly closed container
Away from direct sunlight
Away from excessive heat
According to the supplier's recommended storage conditions
