Sodium Lauryl Sulfate 92% Min (SLS 92% / K12 Needles & Powder) Bag 20kg / 25kg

MONSA® SLS-92 (Needle) – Premium Sodium Lauryl Sulfate for Personal Care, Pharmaceuticals & Textiles

MONSA® SLS-92 (Needle) is a high-purity anionic surfactant based on Sodium Lauryl Sulfate (INCI Name, CAS No.: 151-21-3), commercially known as K12 or SDS. Manufactured via continuous SO₃ falling-film sulfation of selected narrow-cut natural fatty alcohols followed by precision caustic neutralization, it is supplied as free-flowing needle-shaped solid granules. Compared to conventional fine powder grades, the needle physical form drastically reduces workplace dust inhalation and prevents caking during batch transfer. Featuring superior emulsification, rapid flash-foaming, robust surface wetting, and excellent biodegradability, MONSA® SLS-92 is a multi-sector raw material for oral care, personal hygiene, pharmaceutical tableting, and textile dyeing.

Core Specifications Overview – MONSA® SLS-92 (Needle)

Technological Advantages of the Needle Physical Form

• Substantially Reduced Dust Generation: Fine powdered SLS tends to aerosolize during hopper feeding, causing respiratory irritation and requiring extensive dust collection systems. The mechanically stable needle structure virtually eliminates airborne dust, ensuring worker safety and cleaner processing suites.
• Fast Dissolution without Agglomeration: With an optimized surface-area-to-mass ratio, the needle habit dissolves rapidly in ambient or lukewarm water without forming sticky lumps or unhydrated gel masses commonly associated with coarse pellets.
• High Flash-Foaming and Cleansing Dynamics: MONSA® SLS-92 quickly generates rich, elastic, high-volume lather even in hard water conditions, emulsifying hydrophobic soils and oils with high efficiency.
• Ecological Biodegradability: Derived from natural linear fatty alcohols, the surfactant undergoes rapid environmental biodegradation, meeting stringent regulatory compliance criteria for wastewater effluent.

Detailed Industrial Applications Across Market Sectors

Engineered for high chemical consistency and high active concentration, MONSA® SLS-92 (Needle) serves as a functional ingredient across diverse markets:

• 1. Personal Care & Oral Hygiene:
  • Hair Shampoos & Body Washes: Primary surfactant delivering deep scalp and skin cleansing, removing excess sebum, and building a dense, creamy foam blanket that rinses cleanly.
  • Toothpastes & Oral Care: Facilitates paste spreadability throughout the oral cavity, assists in plaque and particulate removal, and provides a pleasant foaming sensation during brushing.
• 2. Pharmaceuticals & Laboratory Applications:
  • Tablet and Capsule Lubricant: Acts as an effective processing aid in dry direct compression and capsule filling, preventing powder adhesion to tooling punch faces and die walls while maintaining uniform tablet hardness.
  • Solubilizing & Wetting Agent: Enhances the dissolution kinetics and gastrointestinal bioavailability of poorly soluble active pharmaceutical ingredients (APIs).
  • Laboratory Detergent: Widely used in biochemical laboratories for membrane protein denaturation, cell lysis, and cleaning analytical glassware.
• 3. Textile Dyeing & Processing:
  • Wetting Agent: Rapidly depresses the surface tension of processing liquors, promoting instantaneous liquor penetration into tightly woven textile fibers to guarantee level dyeing and color uniformity.

Technical Handling Guidelines, Dissolution & Warehouse Storage

• Dissolution Practice: When preparing stock solutions, introduce MONSA® SLS-92 needle granules gradually into warm water (40°C – 50°C) under moderate mechanical agitation. Avoid high-shear blending to minimize excessive aeration and foam buildup.
• Formulation Dosing: Utilize within the recommended range of 0.2% to 25%, depending on targeted foaming performance, viscosity response, and formulation mildness requirements.
• Warehouse Storage Protocol: Store in the original sealed bags in a cool, clean, dry warehouse below 35°C. Elevate pallets on clean racking at least 20 cm above floors to prevent ambient moisture absorption and particle caking.
