Sorbitan Monostearate Span 60

Sorbitan Monostearate (Span 60) is a non‑ionic surfactant derived from sorbitol and stearic acid. It occurs as cream‑white to pale‑yellow brittle waxy flakes with faint fatty odor at ambient temperature, and melts into pale‑yellow liquid when heated above 49‑52℃. With an HLB value of 4.7, it delivers outstanding water‑in‑oil emulsifying capacity. This ingredient exhibits good compatibility with most oils, waxes and other non‑ionic surfactants. It is widely adopted in cosmetic, food and industrial fields to stabilize emulsified systems, adjust viscosity and improve overall formulation performance. It can also be compounded with other emulsifiers to obtain customized emulsion characteristics for different end‑product requirements. It helps resist phase separation during long‑term storage and improves the storage stability of finished products.

This product shows stable surface‑active performance across a broad pH range, and maintains reliable functionality under normal processing temperature conditions.

As a typical water‑in‑oil non‑ionic emulsifier, Span 60 can effectively reduce interfacial tension between oil phase and water phase, forming stable W/O emulsion structure and preventing oil‑water stratification of finished products. It works as an efficient thickening agent to raise system viscosity, optimizing product texture and giving smooth, full‑bodied sensory experience for creams and ointments. It possesses good dispersing capacity, promoting uniform dispersion of solid powder particles inside oily medium and avoiding particle agglomeration and precipitation. It can form a thin protective oil film on material surface, delivering moderate lubricating and anti‑dry effects for skin‑care formulations. When compounded with other surfactants such as Tween series, it is capable of adjusting comprehensive HLB performance, further enhancing the compatibility and overall stability of mixed formula systems.

It is widely used in cosmetic personal‑care industry, suitable for water‑in‑oil creams, ointments, body butter, moisturizing lotions and sunscreen products, helping to build stable emulsion texture and improve skin‑feel performance. In food industry, it serves as food‑grade emulsifier and stabilizer for margarine, shortening, bakery products and chocolate‑related food systems to avoid oil precipitation. It applies to pharmaceutical ointment and topical cream preparations, playing an emulsifying and dispersing role for medicinal active components. It is also utilized in chemical industrial area, acting as dispersant, lubricant and anti‑fogging agent for plastics, coatings and textile auxiliary formulations. When matched with Tween series emulsifiers, it can be further applied in more customized emulsification projects for different industrial manufacturing demands.

Besides the above mainstream usages, this product can be added into candle and wax‑based products to improve wax dispersion and inhibit surface blooming. It can also be used in pesticide auxiliary formulations to assist the dispersion of oil‑soluble active ingredients.
