Sorbitan monopalmitate (SMP) can be mixed with castor oil to prepare a calcium phosphate composite castor oil-based gel using a water-in-oil emulsion method. The detailed procedure is as follows:
Mixing: Combine 820 µL of castor oil and 0.25 g of SMP in a 10 mL vial. Stir the mixture at 700 rpm while heating to 60°C until a uniform mixture is obtained.
Emulsification: Add 100 µL of calcium chloride dihydrate (CaCl₂·2H₂O, 7.2 M) to the mixture and continue stirring for 30 minutes to form an emulsion.
Reaction: Slowly add 700 µL of disodium hydrogen phosphate (Na₂HPO₄) aqueous solution using a pipette, and continue stirring the mixture for 1 hour to complete the reaction.
Gel Formation: Allow the hot mixture to cool and solidify at room temperature, forming the gel.
This method ensures the formation of a stable calcium phosphate composite gel with castor oil and SMP as the base materials.

This case study aims to investigate the effect of the surfactant sorbitan monopalmitate (SMP) on the gelation process of ethyl cellulose (EC). The goal is to enhance curcumin loading by reducing lipid oxidation while also improving the solubility and chemical stability of curcumin.
Morphological Analysis: Samples prepared without SMP exhibited a wide pore size distribution and a highly uneven gel network. Some areas were nearly collapsed due to the connection of large pores. When small amounts of SMP were added, the number of large pores decreased, and this effect became more pronounced with increasing SMP content. Larger pores in the network trapped larger oil droplets, adversely affecting macroscopic properties.
Rheological Properties: Rheological data showed improved viscoelastic properties of the oleogels prepared with SMP. This improvement is likely due to interactions between the surfactant and the polar entities of the EC main chain.
Functional Benefits: The formation of a more compact network had a direct impact on inhibiting the crystallization of curcumin, slowing lipid oxidation, and providing resistance to UV exposure.
The addition of SMP to the EC gelation process significantly improves the structural integrity and functional performance of the oleogels. This enhancement is attributed to the surfactant's ability to reduce pore size and interact with the EC network, resulting in better curcumin loading, increased solubility, and greater chemical stability.
