The effectiveness of an emulsifier is largely determined by its Hydrophilic-Lipophilic Balance (HLB) value, a scale that quantifies its relative solubility in oil versus water. For Polysorbate 85 (CAS 9005-70-3), its specific HLB value positions it as a crucial ingredient for formulators, particularly in creating stable oil-in-water (O/W) emulsions. As a dedicated chemical supplier, understanding this property is vital for advising our clients.

Polysorbate 85, being an ethoxylated sorbitan trioleate, possesses a higher HLB value, typically around 11.0. This value indicates a strong preference for the aqueous phase, making it an excellent candidate for O/W emulsions. In these systems, the oil is dispersed as small droplets within a continuous water phase. The hydrophilic nature of Polysorbate 85 allows it to surround the oil droplets, creating a protective barrier that prevents them from coalescing.

This characteristic makes Polysorbate 85 invaluable in numerous applications. In the cosmetic industry, it is used to create light and easily spreadable lotions and creams, where oil droplets are suspended in a water base. For food manufacturers, its high HLB is beneficial for stabilizing dressings, sauces, and dairy-based products, ensuring a smooth and uniform consistency. The ability to buy high-quality Polysorbate 85 with a consistent HLB is essential for achieving predictable formulation results.

Often, formulators achieve optimal stability by using Polysorbate 85 in combination with a lower HLB emulsifier, such as a Span product. This synergy allows for precise control over the emulsion’s properties. For instance, combining a low HLB Span with a high HLB Tween can create emulsions with intermediate HLB values, suitable for a broader range of ingredients.
