Technical grade

A very common detergent / surfactant which is found in many personal care products including soaps, shampoos, lotions etc. It is also used in washing up liquids, providing detergency and excellent stable foam. Other uses include general cleaners and degreasers, vehicle washes , thickening agent for thick bleaches and dry foam carpet cleaners. It is an anionic surfactant, which means it carries a negative charge when dissolved in water, helping it to remove dirt and oils effectively.

Key Properties:

• Chemical Structure: SLES is derived from ethoxylated lauryl alcohol (usually from coconut or palm kernel oil) and sulfur trioxide (or sulfuric acid). It has a hydrophilic (water-attracting) sulfate group and a hydrophobic (oil-attracting) alkyl chain.
• Physical Form: It typically appears as a clear or pale yellow liquid.
• Molecular Formula: C₁₂H₂₅O(C₂H₄O)ₙSO₃Na (where "n" represents the number of ethylene oxide units, usually 1-3).

Common Uses:

1. Personal Care Products:
   • Shampoos: SLES helps to create a rich lather and cleanse the scalp.
   • Body washes and soaps: It effectively removes oils and dirt from the skin.
   • Facial cleansers: SLES works as a foaming agent to remove impurities.
2. Household Cleaning Products:
   • Dishwashing liquids: SLES aids in cutting through grease.
   • Laundry detergents: It helps break down oils and stains in fabrics.
3. Industrial Cleaning Products:
   • Found in formulations for heavy-duty cleaning solutions due to its strong detergent properties.
