Sorbitan monostearate, commercially known as Span 60, is a high-grade non-ionic emulsifier derived from stearic acid and sorbitol. It is typically a cream-colored to light yellow waxy solid, with good oil solubility and dispersibility in hot water. As a type of lipophilic emulsifier, it is mainly used to stabilize water-in-oil (W/O) emulsion systems, and can also be compounded with hydrophilic emulsifiers like Tween series to adjust the hydrophilic-lipophilic balance (HLB) value for different emulsion formulations.
Span 60 features excellent thermal stability and chemical inertness, maintaining stable performance across a wide pH range. It is non-toxic, mild to the human body, and compliant with food safety standards in most countries and regions, making it widely applicable in food, cosmetics, pharmaceuticals and industrial fields.

Main Application Fields

  1. Food IndustryIt is a commonly used food additive, serving as an emulsifier, stabilizer and anti-caking agent. In the production of margarine, shortening and cream, it helps disperse water phase evenly in oil phase, preventing oil-water separation and improving product texture and shelf life. It is also added to baked goods such as bread, cakes and biscuits to enhance dough elasticity, improve product softness and extend freshness. In ice cream production, it can inhibit ice crystal growth, making the product smoother and creamier.
  2. Cosmetics and Personal Care IndustryAs a key emulsifier for W/O skincare products, it is widely used in nourishing creams, body lotions, sunscreen creams and foundation creams. It can effectively emulsify water components into oil phase, forming stable and fine-grained emulsions with a rich and non-greasy texture. It also acts as a thickener and conditioning agent, improving the spreadability of products and enhancing skin compatibility, leaving the skin soft and smooth after application.
  3. Pharmaceutical IndustryIt is used as an emulsifier, solubilizer and dispersant in the preparation of pharmaceutical preparations. In the production of W/O type ointments, creams and suppositories, it helps disperse water-soluble active pharmaceutical ingredients evenly in the oil-based matrix, improving the uniformity and stability of preparations. It can also be used as a carrier for fat-soluble drugs, enhancing the dissolution and absorption of drugs in the body.
  4. Industrial ApplicationsIn the textile industry, it serves as a softener and antistatic agent, improving the hand feel of fabrics and reducing static electricity generated during weaving and processing. In the pesticide industry, it is used as an emulsifier for pesticide emulsions, helping to disperse insoluble pesticide active ingredients evenly in water, improving the adhesion and permeability of pesticides on crop surfaces, and enhancing pesticide efficacy. It is also applied in the production of water-based coatings and inks as a dispersant and stabilizer, promoting the uniform dispersion of pigments and fillers and improving the quality of coating films and printed products.
