SLS Powder (Needles)

Sodium Lauryl Sulfate (Needle Form)

Sodium Lauryl Sulfate (SLS) is a potent anionic surfactant known for its exceptional cleaning and high-foaming properties. Ruvon supplies SLS in **Needle Form**, which is superior to fine powder as it is non-dusting, free-flowing, and easier to handle in production environments. It is the gold standard for oral care and pharmaceutical applications.

Form White Needles

Product Overview

Sodium Lauryl Sulfate (SLS), often referred to as K12, is an anionic surfactant derived from coconut or palm kernel oil. It functions as a detergent, wetting agent, and emulsifier. While SLES is preferred for liquids, SLS is preferred for powders, tablets, and applications requiring a "drier" foam.

  • High Purity: With >92% active matter, it is significantly more concentrated than liquid surfactants (which are usually 28-70%).
  • Hard Water Tolerance: Excellent foaming capabilities even in hard water conditions.
  • Pharmaceutical Grade: Suitable for use as an excipient in tablets (lubricant/wetting agent).

Particle Engineering: Why Needles?

The Advantage Over Powder

Traditional SLS comes in a fine powder which creates significant dust clouds during handling, posing a respiratory hazard to factory workers. Our **Needle Form** technology solves this:

  • Low Dust: The larger particle size prevents airborne dust, improving worker safety.
  • Better Solubility: Needles disperse more easily in water without clumping (forming "fish eyes") compared to fine powder.
  • Free Flowing: Needles flow smoothly through hoppers and automated dosing systems without bridging or blocking.

Industrial Applications

Oral Care (Toothpaste)

The primary foaming agent in 90% of toothpastes worldwide. Provides the "clean" feeling.

Pharmaceuticals

Used in tablet manufacturing as a lubricant and wetting agent to aid dissolution.

Powder Detergents

High-foaming active ingredient for premium laundry powders.

Solid Shampoos & Bars

Used in "Syndet" bars and solid shampoo bars where liquid content must be low.

Carpet Cleaners

Forms dry, brittle foam that encapsulates dirt, which can then be vacuumed away.

Emulsion Polymerization

Emulsifier for PVC, latex, and rubber manufacturing processes.

Packaging Options

20 KG / 25 KG Bags

Multi-ply paper bags with PE inner liner to protect against moisture.

Palletized Shipping

Shrink-wrapped pallets ensuring stability during transport.

Safety & Handling Protocols

Safety First

While Needle form reduces dust, SLS is a strong surfactant.

  • Inhalation: Avoid breathing dust. Even with needles, wear a dust mask during hopper charging.
  • Skin/Eye Contact: Can cause irritation. Rinse immediately with water if contact occurs.
  • Fire Safety: Combustible solid. Keep away from open flames.
