Frequently Asked Questions
What is the full form of SLES in chemicals?
SLES stands for Sodium Lauryl Ether Sulphate, also known as Sodium laureth sulfate, LES 70. Its CAS number is 68585-34-2. Supreme Petro Chemicals supplies SLES Liquid / Paste to manufacturers from Chennai.
What is SLES and what is it used for?
SLES stands for Sodium Lauryl Ether Sulphate, also written Sodium Laureth Sulfate in US spelling. It is an anionic surfactant used as the primary foaming and cleansing base in detergents and personal-care formulations such as shampoos and liquid soaps.
What is the CAS number of Sodium Lauryl Ether Sulphate?
Our product listing carries CAS 68585-34-2. The technical data sheet carries the dual reference 9004-82-4 / 68585-34-2, both of which are used for this surfactant.
What does "SLES 70, 2 mole" mean?
SLES 70 (also written LES 70) is the nominal 70% active trade grade. The specification we carry against it is Active Matter (MW 384) 68.0 % mass minimum. "2 mole" is the average degree of ethoxylation — 2 moles of ethylene oxide per mole. The grade we stock is Technical Grade (LES 70, 2 mole).
What is the specification of SLES 70?
Against the manufacturer's Certificate of Analysis, the grade we carry runs Active Matter (MW 384) 68.0 % mass min, pH 6.5 – 8.5 in 1% aqueous solution, colour 25 APHA max on a 20% aqueous solution, and 1,4-Dioxane 30 ppm max on 100% active matter. Sulphate as Na2SO4 is 1.5 % mass max, unsulphated matter (NDOM) 3.0 % mass max, iron as Fe 5 ppm max and heavy metals as Pb 15 ppm max.
Do you supply SLES in both liquid and paste form?
Yes. We supply both, and each form carries its own safety data sheet on our site — SLES Liquid and SLES Paste. The specification we carry describes a high viscous, colourless material. Store it in closed containers away from heat and keep it from freezing, since freezing causes phase separation.
Do you supply SLES 70 in Chennai, and what packaging is available?
Yes. We supply SLES in drums from our Redhills warehouse in Chennai, with dispatch across South India. The HSN code is 3402 11 90. Order sizes depend on packaging and current stock — call or WhatsApp +91 86087 80096 for a quote.
