Description

Application

• Agglomeration of celecoxib by quasi-emulsion solvent diffusion method without stabilizer: effect of good solvent.: This research explored the agglomeration of celecoxib using the quasi-emulsion solvent diffusion method, highlighting the role of methyl acetate as a good solvent to improve particle size and distribution without the need for stabilizers (Maghsoodi & Nokhodchi, 2018).
• Formulation and in vitro evaluation of ketoprofen in palm oil esters nanoemulsion for topical delivery.: The formulation and evaluation of ketoprofen in a nanoemulsion system for topical delivery were examined, with methyl acetate used as a solvent to enhance solubility and stability of the active ingredient (Sakeena et al., 2010).
• Preparation of surfactant-free nanoparticles of methacrylic acid copolymers used for film coating.: This paper presented a method for preparing surfactant-free nanoparticles using methyl acetate as a solvent, emphasizing its role in the formation of uniform nanoparticle dispersions for coating applications (Nguyen et al., 2006).
