Abstract

Bovine colostrum is a bioactive compound with potential in cosmetic applications but has a limited shelf life. This study aimed to develop an effective encapsulation system for bovine colostrum using the complex coacervation method and incorporate it into powder formulations for facial masks. The research explored various gelatin-to-gum Arabic ratios to optimize the physical and chemical stability, encapsulation efficiency, and loading capacity of the encapsulated bovine colostrum (EBC). The EBC was further incorporated into powder formulations for clay masks, peel-off gel masks, and sleeping gel masks. The optimal gelatin-to-gum Arabic ratio was found to be 2:1, yielding the highest entrapment efficiency (66.6 ± 3.3% w/w) and loading capacity (67.6 ± 3.4% w/w) of bovine colostrum. For clay masks, the most effective powder blend incorporating EBC enhanced the moisture content, water solubility, and hygroscopicity, without affecting the drying time (9.7 ± 0.6 min). Additionally, peel-off gel masks incorporating EBC significantly reduced water activity and improved moisture content and hygroscopicity, while the drying time decreased from 44.3 ± 0.6 to 25.0 ± 1.7 min. For sleeping gel masks, the formulation with EBC increased water activity, while other parameters remained stable. In conclusion, the EBC with enhanced stability was effectively integrated into various powders for facial mask formulations.
