Sodium Laureth Sulfate (CAS 68585‑34‑2) supplied by Global Optimals is a 70 % paste grade with impurity levels not exceeding 1.5 %. The surfactant is produced by ethoxylating lauryl alcohol followed by sulfation, which creates a molecule that combines a hydrophobic 12‑carbon tail with a highly hydrophilic sulfate head. This amphiphilic architecture lowers the surface tension of water and promotes micelle formation at concentrations as low as 0.1 % wt, enabling gentle removal of oils and soils without harsh irritation. Because of its strong ability to generate stable foam, SLES is a workhorse in shampoo, shower‑gel, liquid‑soap and laundry‑detergent formulations, where it provides abundant, long‑lasting bubbles and helps distribute other actives evenly across hair fibers or textile strands. When blended with cationic conditioners (e.g., quaternary ammonium compounds) it forms compatible complexes that preserve softness while preventing precipitation. Pairing SLES with non‑ionic surfactants such as cocamidopropyl betaine yields a synergistic boost in foam volume and emulsion stability, a feature prized in hair‑mask, cream and lotion applications. The high purity supplied by established manufacturers (KCC, Kukdo, Evonik, BASF) eliminates phosphate residues and keeps residual salt content low (≤1.5 %), a critical factor for products aimed at sensitive skin. Recommended storage conditions are a dry, cool environment (15‑25 °C) in sealed containers protected from moisture and direct sunlight. Shelf life under proper storage is 24 months. Formulators should monitor the overall foam index and ionic strength when SLES is combined with other surfactants to avoid excessive foaming in automated dosing lines. Practical handling guidelines include adding SLES to the water phase at 40‑60 °C to ensure complete dissolution, then cooling the blend before incorporating temperature‑sensitive actives. Transport should use closed plastic or metal drums marked according to GOST R 51178‑96, preventing contamination and meeting international quality expectations.

SLES paste should be stored at ambient temperature, ideally between +5 °C and +25 °C, in a dry, well‑ventilated area protected from direct sunlight and heat sources. When packaging integrity is maintained, the typical shelf life is up to 24 months. During transport and storage, avoid mechanical damage and contact with strong oxidizers. The product is supplied in sealed metal drums or robust plastic containers; ensure closures remain tight to prevent moisture ingress and contamination, which could alter pH and performance.
