Sodium Lauryl Ether Sulfate (SLES 70%)

What is SLES 70%?
Sodium Lauryl Ether Sulfate (SLES 70%) is a sodium salt of the fatty alcohol ethoxysulphates, a type of anionic surfactant in the group of ethoxylated alkyl sulfates. It is a highly effective foaming agent, widely used in cleaning and hygiene products for its ability to generate significant amounts of foam and provide efficient cleaning.

• Density: 1.05 g/cm³
• Molar Mass: 384 g/mol
• pH of 1% aqueous solution: 7.25
• Boiling Point: 100°C
• Freezing Point: 8-12°C
• Flashpoint: Above 94°C
• Self-ignition: 310°C
• Water Solubility: Soluble in water, forming clear solutions (may turn yellow or brown).
• Stability: Stable with acids and alkalis.
• Foam Production: Excellent foaming capabilities, even in hard water.
• Compatibility: Compatible with other surfactants, such as anionic and amphoteric surfactants.

Applications:

SLES 70% is used across a wide range of industries, primarily for its detergent properties, including:

• Personal Care Products: Liquid soaps, facial cleansers, makeup removers, shaving creams, intimate hygiene products, shampoos, shower gels, and bath foams.
• Household Cleaning Products: Dishwashing liquids, floor cleaners, glass cleaners, laundry detergents, and stain removers.
• Industrial Applications: It is also used as a foaming agent, emulsifier, and degreaser in pharmaceuticals, printing, textile, and leather industries.
• Automotive: Car cleaning products and automotive cosmetics.

Safety Considerations:

• Non-toxic and non-carcinogenic: SLES is generally considered safe when used according to guidelines.
• Skin Irritation: Concentrated solutions may cause irritation for people with sensitive skin, so it is advisable to rinse off thoroughly after use.
• Inhalation Risks: Inhalation of concentrated vapors may irritate the respiratory system.
• Handling: Use appropriate personal protective equipment (PPE) such as gloves and goggles when handling concentrated forms of SLES.

Storage:

SLES 70% should be stored in a dry, well-ventilated area away from direct sunlight, moisture, and extreme temperatures (optimal storage temperature: 5-30°C). It is typically packaged in plastic drums (170-220L) or IBC totes and has a shelf life of one year from the date of manufacture.

Packaging and Transport:

SLES 70% is typically transported using standard methods, as it is not classified as hazardous. However, precautions should be taken to prevent contamination, and proper ventilation should be maintained during storage and transportation.
