Abstract
The data article refers to the paper “Effect of solvent type on preparation of ethyl cellulose microparticles by solvent evaporation method with double emulsion system using focused beam reflectance measurement” [1]. Data presented here include the effect of solvent type, method of emulsification (an oil-in-water (O/W) or a water-in-oil-in-water (W/O/W)), external aqueous phase volume, stirring speed and ethyl cellulose concentration on the preparation of ethyl cellulose microparticles. Data also refer to the effect of above mentioned factors on the solidification rate, hardening time, particle size, particle size mean, chord length distribution (CLD) and chord count of microparticles. Additionally, data exhibit process parameters when emulsion droplets transformed into solid microparticles during fabrication. The transformation of the emulsion droplets into solid microparticles occured within the first 10, 10.5, 12 and 60 minutes (O/W), and the first 12, 11.5, 10 and 90 minutes (W/O/W) when dichloromethane/methanol (1:1), dichloromethane, ethyl acetate and chloroform were used respectively. Either in O/W and W/O/W emulsion system, Chloroform gave smallest square weighted mean chord length. In contrast, its chord counts was not to be the highest.

Chemistry Polymer Chemistry Table Graph Figure FBRM, SEM Raw Analyzed - To measure solidification time, data were collected from emulsion droplet which in time showed constant particle size which is assumed as formation of solid microparticles. - At the time when solid microparticles were formed, the FBRM will count particle size means as well as the distribution of particle size of those solid microparticles
The length of solid microparticles were collected as the particle size data, while amount of particles distributed and detected by beam was recorded as particle count as well as the distribution of particle size
Summary
The data presented here describe the influence of solvent type and emulsification method, on particle size of ethyl cellulose microparticles (Table 1). On line monitoring on the effect of solvent type on square weighted mean chord length during microparticles formation at different method of emulsification (O/W and W/O/W) was performed by employing FBRM method On line monitoring by FBRM can study the effect of stirring speed on (a) square weighted mean chord length and on (b) the number of chord counts during evaporation process (Fig. 6). Data on the effect of external phase volume on square weighted mean chord length (a) and the number of chord counts (b) during solvent evaporation process was presented (Fig. 8).
