Sodium Lauryl Ether Sulfate (SLES)

Sodium Lauryl Ether Sulfate (SLES) is a surfactant derived from ethoxylated lauryl alcohol that effectively reduces surface tension between substances, facilitating cleaning and emulsification processes. It typically appears as a clear to slightly hazy viscous liquid supplied in industrial concentrations ranging from 27% to 30%. This grade of SLES combines strong foaming ability with mild skin-irritation profiles, making it suitable for both industrial cleaners and personal care product manufacturing. Finstar supplies SLES with typical use concentrations between 5% and 15% in formulations, depending on the application, and recommends avoiding storage temperatures below 10C to prevent gel formation. It is compatible with water and alcohol-based solvents but should not be mixed with strong oxidizing agents or cationic surfactants, which may impair its efficacy and stability. Buyers should handle the material with care, considering its anionic surfactant nature and appropriate personal protective equipment.

In detergent formulation, Sodium Lauryl Ether Sulfate solves challenges related to effective dirt removal and foam stability, critical for user satisfaction and cleaning power. Its balanced foaming and wetting properties ensure thorough soil removal from textiles and surfaces without excessive skin irritation, essential for both consumer products and industrial cleaning agents. Additionally, its emulsifying capability enhances formulation homogeneity, improving shelf life and performance consistency in both liquid and solid products. Using SLES helps manufacturers optimize ingredient interactions, ensuring end products meet required cleaning standards efficiently and reliably.
