Macrogol Stearates are synthesized by ethoxylation of mainly stearic acid. The number in the product name indicates the average polymer length in ethylene oxide units. As a general rule of thumb, the higher the ethoxylation grade, the more hydrophilic the Macrogol Stearate.
Macrogol Stearates are mainly used as emulsifiers in oil in water creams and lotions, and have particular good emulsifying properties in presence of strong electrolytes. They are also very good solubilizers in liquid dosages and used as wetting agents for tableting.
Macrogol Stearates are blendable with a range of other surfactants to achieve desired formulation characteristics. Please refer to related articles section below for further available Macrogol Stearate grades.
Hedjuvan-MS products have exceptional low water content and acid value to meet requirements of demanding applications.
