This study aims to research the effects of rosin acid (RA) and size of starch on the properties of Pickering emulsifier. Potato (PS, 10–100 µm), corn (CS, 5–25 µm), and rice (RS, 3–8 µm) starches are modified with RA, and their starch ester is used to prepare Pickering emulsions. The results of scanning electron microscopy, X‐ray diffraction, and nuclear magnetic resonance hydrogen spectrum analysis reveal that the structure of native starch is largely destroyed, and esterification occurs between starch and RA. The starch‐based Pickering emulsion, which is esterified by RA, has the uniform particle size and higher stability than native starch. With prolonged storage, the emulsion of large‐sized RA–starch (PS and CS) show a stable gel phenomenon, and the emulsion of small‐sized RA–starch (RS) is a Newton fluid. In addition, the results indicate that RA–starch displays high viscosity and emulsifying properties.

“…It can be used directly as an epoxy resin hardener, but its applications are much wider. They include preparation of epoxy resins [83,84], acrylic resins [85,86,87], allyl resins [88,89,90], polyols [91], bio-based curing agents for synthetic epoxy resins [92,93,94,95,96,97,98] or bio-based ones [99], surfactants [100,101,102,103], intermediates [104,105], biologically active compounds [105,106,107,108], polyurethanes [109,110,111,112], chemicals for NMR techniques [113] and photolitography [114], sorbents [115], organosilicon compounds [116], printing inks [117] and for the hydrophobization of wood surfaces [118,119,120]. It is noteworthy that the main degradation products of maleopimaric acid are water, carbon dioxide, formamide and also aliphatic and aromatic derivatives [121].…”

A comprehensive review of the publications about rosin-based chemicals has been compiled. Rosin, or colophony, is a natural, abundant, cheap and non-toxic raw material which can be easily modified to obtain numerous useful products, which makes it an excellent subject of innovative research, attracting growing interest in recent years. The last extensive review in this research area was published in 2008, so the current article contains the most promising, repeatable achievements in synthesis of rosin-derived chemicals, published in scientific literature from 2008 to 2018. The first part of the review includes low/medium molecule weight compounds: Especially intermediates, resins, monomers, curing agents, surfactants, medications and biocides. The second part is about macromolecules: mainly elastomers, polymers for biomedical applications, coatings, adhesives, surfactants, sorbents, organosilicons and polysaccharides. In conclusion, a critical evaluation of the publications in terms of data completeness has been carried out with an indication of the most promising directions of rosin-based chemicals development.
