SG-40
Jienuo
Core functions include emulsification, stabilization, solubilization, and wetting . Widely used in cosmetics (creams, shampoos), pharmaceuticals (ointment bases, enhancing drug bioavailability), food (stabilizing margarine/creams), and textiles (softeners) . It's stable in electrolytes and soluble in water/alcohols .
Product Advantage
Superb Emulsifying Performance: With an HLB value of 16.5 - 17.5, it efficiently emulsifies oil - in - water systems. In tests, it reduces the particle size of emulsified droplets to below 5μm, ensuring long - term emulsion stability for over 6 months.
Excellent Compatibility: Compatible with various ionic and non - ionic surfactants. When compounded with anionic surfactants, it enhances foaming and cleaning capabilities by 30% as per lab data.
High Purity and Stability: Manufactured with advanced purification tech, impurity content is less than 0.5%. Stable in electrolyte solutions and maintains performance over a wide pH (5.0 - 9.0) and temperature (-5℃ to 120℃) range.
Good Solubilization Ability: Can solubilize hydrophobic substances like essential oils. For example, it increases the water solubility of lavender essential oil by 80 times compared to no surfactant.
Low Toxicity and Safety: Tested to have an LD50 (oral, rat) > 5000 mg/kg, meeting safety standards for cosmetics, pharmaceuticals, and food applications.

Product Uses
Cosmetics Industry: Used in creams, lotions, and shampoos as an emulsifier and stabilizer. It helps create smooth textures and prevents phase separation, improving product shelf - life.
Pharmaceuticals Field: Serves as an ointment base component and enhances drug bioavailability by solubilizing poorly water - soluble drugs, aiding in better absorption.
Food Sector: Stabilizes margarine and dairy creams, preventing fat crystallization and ensuring a consistent, creamy texture.
Textile Industry: Acts as a softener and antistatic agent for fabrics, reducing static electricity and making textiles feel smoother.
Add Emulsifier SG - 40 to the oil or water phase (based on formulation) during product manufacturing. Stir well at a temperature of 50 - 80℃ to ensure uniform dispersion.
