[Ester Composition and HLB]

[Ester Composition and HLB]    <Hydration> <Fat crystal control> The affinity of SURFHOPE SE COSME for the water phase in an emulsion is derived from the hydroxyl groups (A) of the sucrose part of the molecule. SURFHOPE SE COSME yield emulsions which are exceptionally heat stable. Since the hydration of hydroxy groups is far stronger than the hydration of ether groups(B) in ethoxylate emulsifiers, SURFHOPE SE COSME are, especially at higher temperatures used in heat stabilization. Low HLB SURFHOPE SE COSME can modify the crystalline structure of solid triglycerides with useful benefits to the physical properties of the product.       <Oil in water emulsion> <Water in oil emulsions> SURFHOPE SE COSME with medium-high hydrophilic-lipophilic balance (HLB) value, tend to form liquid crystal structures in aqueous solutions. SURFHOPE SE COSME very efficiently cover the surface of emulsions because of their compact structure . Low HLB SURFHOPE SE COSME give very stable water in oil emulsions, and can be used to obtain very high rations of water dispersed in the continuous oil phase.
