Features Of Croda Span 65 Sorbitan Tristearate Nonionic Surfactant

  1. Highly effective oil-in-water (O/W) emulsifier with excellent stability in high-oil-load systems.

  2. Low HLB value (approximately 2.1) makes it ideal for formulating water-in-oil (W/O) emulsions and reverse emulsions.

  3. Thermally stable and compatible with a broad range of oils, waxes, and polar actives.

  4. Nonionic nature ensures low sensitivity to electrolytes and pH variations across typical formulation ranges.

  5. Derived from renewable sorbitol and stearic acid, supporting sustainable ingredient sourcing initiatives.

Typical Applications Of Croda Span 65 Sorbitan Tristearate Nonionic Surfactant

  1. Food-grade emulsions including margarines, shortenings, and bakery fillings.

  2. Pharmaceutical ointments and topical suspensions requiring robust W/O structure.

  3. Cosmetic creams and lotions where low-irritancy and high-spreadability are critical.

  4. Industrial metalworking fluids and lubricant emulsions demanding shear and thermal resistance.

  5. Agrochemical formulations such as suspension concentrates (SC) and emulsifiable concentrates (EC).
