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.

- 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.
