Product Advantage
Superior Emulsification Efficiency: With an HLB value of 17.5-18 (optimized for oil-in-water systems), it achieves uniform emulsification in 5-10 minutes (30% faster than general emulsifiers). Our product has a purity of ≥99.5% (tested by HPLC), ensuring consistent performance without impurities affecting end products.
Broad Solubility & Compatibility: It dissolves easily in water, ethanol, and carbon tetrachloride, and is compatible with 90% of common surfactants (e.g., sodium lauryl sulfate) and raw materials in pharma/cosmetics. This reduces formulation difficulties and avoids compatibility issues.
Stable Storage & Safety: Non-toxic (meets FDA 21 CFR 172.838 standards) and non-flammable, it maintains stability for 2 years under normal storage (20-25℃, dry environment). No degradation or performance loss occurs, reducing inventory waste for customers.
Multi-Functional Performance: Beyond emulsification, it provides thickening (increases solution viscosity by 20-30% at 0.5% dosage) and antistatic effects (reduces textile surface resistance to ≤10⁸Ω). One product replaces multiple additives, cutting production costs.
Industrial-Grade Customization: We offer dosage adjustment guidance (0.1-2% recommended) based on customer scenarios (pharma/cosmetics/textiles). Our production capacity reaches 500 tons/month, ensuring on-time delivery with a 98% order fulfillment rate.

Product Uses
Pharmaceutical Industry: Used as an emulsifier (for oral emulsions like cod liver oil emulsion) and solubilizer (for fat-soluble drugs such as vitamin E), and as an ointment base. It improves drug solubility and stability, ensuring uniform drug release.
Cosmetics Industry: Applied in creams (e.g., moisturizing face cream) and lotions. It emulsifies oil-phase ingredients (e.g., mineral oil) into water-phase, creating a smooth texture and enhancing product spreadability.
Food Industry: Acts as an emulsifier in dairy products (e.g., milk shakes) and baked goods (e.g., bread). It prevents oil-water separation, extends food shelf life by 3-5 days, and improves texture.
Textile Industry: Used as a softener and antistatic agent for cotton/polyester fabrics. It forms a protective film on fabric surfaces, reducing static and making fabrics softer to the touch.
For general emulsification:
1. Dissolve Emulsifier SG-50 (0.1-2% of total formulation) in water at 50-60℃ under stirring (300-500 rpm).
2. Add oil-phase ingredients slowly to the aqueous solution, continuing to stir for 5-10 minutes until uniform.
3. Cool to room temperature for use. Adjust dosage based on system viscosity; test small batches first for special formulations.
FAQ
Q1: What is the recommended dosage of Emulsifier SG-50?
A1: The general dosage is 0.1-2% of the total formulation. For pharmaceuticals (e.g., ointments), use 0.5-1%; for cosmetics (e.g., creams), use 0.3-0.8%. Adjust based on specific product requirements.
Q2: Is Emulsifier SG-50 safe for food contact?
A2: Yes. It meets FDA 21 CFR 172.838 and EU EC No. 1333/2008 standards, making it safe for food-grade applications like dairy products and baked goods.
Q3: How to store Emulsifier SG-50 properly?
A3: Store in a dry, cool place (20-25℃) away from direct sunlight and moisture. Seal the package after opening to avoid absorption of water, which may affect solubility.
Q4: Can it be used in water-in-oil (W/O) emulsions?
A4: No. Its HLB value (17.5-18) is suitable for oil-in-water (O/W) emulsions. For W/O systems, we recommend our Emulsifier SG-10 (lower HLB) for better performance.
