Span series refer to Sorbitan Fatty Acid Esters, a widely used non‑ionic surfactant including six main types: Span 20, Span 40, Span 60, Span 65, Span 80 and Span 85, each with different hydrophilic‑lipophilic balance (HLB) values, chemical structures and applicable scenarios. Span 20 (CAS 1338‑39‑2, HLB 8.6, amber oily liquid) is the most hydrophilic grade with excellent wetting and solubilizing effects, commonly used in cosmetics, body care products and food flavor emulsification; Span 40 (CAS 26266‑57‑9, HLB 6.7, pale yellow waxy solid) features balanced lipophilicity and hydrophilicity, suitable for creams, ointments and baked food emulsifiers; Span 60 (CAS 1338‑41‑6, HLB 4.7, off‑white waxy solid) is a general‑purpose water‑in‑oil emulsifier with stable thickening performance, widely applied in cosmetic skincare, food margarine and coatings; Span 65 (CAS 26658‑19‑5, HLB 2.1, light yellow waxy solid) has strong lipophilicity and high‑temperature resistance, mainly used in high‑fat food, industrial lubricants and pesticide emulsifiers; Span 80 (CAS 1338‑43‑8, HLB 4.3, amber viscous liquid) is the most versatile type with good fluidity at room temperature, extensively adopted in cosmetics, pharmaceuticals, textiles and pesticide additives; Span 85 (CAS 26266‑58‑0, HLB 1.8, amber oily liquid) possesses ultra‑high lipophilicity, ideal for heavy‑duty industrial emulsification and oilfield auxiliaries. All models are available in industrial grade, cosmetic grade and food grade with strict impurity control, low irritation and good compatibility with Tween series and other surfactants, suitable for emulsification, dispersion, stabilization and wetting in food, personal care, pharmaceutical, textile, coating and pesticide industries.
Food‑grade Span products have strict control over heavy metals, peroxide value and free acid, complying with food additive standards for direct food‑contact applications. Cosmetic‑grade ones feature low‑irritation and mild odor, specially refined for skincare and personal care raw materials. Industrial‑grade versions meet basic surface‑active requirements with cost‑effective performance, mainly used in textiles, coatings, pesticides and other industrial fields.
Standard package: 25kg plastic drum or paper drum. Bulk options include 200kg iron drum and IBC tank. Small trial packages are also available for sample testing.
Span series are oil‑soluble materials. It is recommended to mix them with the oil phase first, heat solid grades to melt, then add water phase under continuous stirring. Compound with Tween series can adjust HLB value for better emulsion stability. Recommended dosage is 0.5%‑5% for food and cosmetics, 1%‑10% for industrial applications.
Food industry: Emulsifiers and stabilizers for margarine, ice cream, baked goods and essence.
Cosmetic & personal care: Used in cream, lotion, mask and body care products.
Pharmaceutical industry: Ointment base and emulsifier for drug carriers.
Industrial fields: Textile oil agents, coating dispersants, pesticide emulsifiers and oilfield additives.
Complete Span series models for one‑stop purchase, stable quality with batch‑to‑batch consistency, good compatibility with other surfactants, flexible packaging, fast delivery and professional technical support for formula adjustment.
