Sustainable Polyurethane Networks Based on Rosin with Reprocessing Performance

Polymers, 2021
Rosin is an abundant natural product. In this paper, for the first time, a rosin derivative is employed as a monomer for the preparation of polyurethane vitrimers with improved properties.

On the skin sensitisation potential of rosin and oxidised rosin

Regulatory Toxicology and Pharmacology, 2008
In the EU rosin is classified as a skin sensitiser, apparently on the basis of its oxidation to sensitising agents. Rosin (gum, tall oil or wood) is not a skin sensitiser when examined in the guinea pig maximisation test (GPMT). Oxidised rosins are sensitisers in the GPMT. Oxidised gum rosin was further tested in the mouse local lymph node assay (LLNA)

Study of Rosin and Rosin esters as coating materials

International Journal of Pharmaceutics, 1985
Rosin esters were prepared by heating glycerol, sorbitol and mannitol. Aspirin granules were coated with solution of Rosin and Rosin esters in acetone. The coated granules were studied for moisture absorption, dissolution studies, and ageing studies. The results showed that rosin-coated granules release less than 10% drug in gastric media in 3 h and ...

Rosin coacervate microcapsules: effect of solvent on phase separation of rosin

Journal of Microencapsulation, 1993
The effect of various solvent-non-solvent pairs on phase separation of rosin was studied visually and microscopically. The type of phase separated was found to be a function of viscosity of the solution rather than the dielectric constant of the solvent. Triangular phase diagrams were constructed and optimum coacervation conditions were determined.

The Use of Rosin and Activated Rosin Fluxes

1957
Considerable information has been published over the past twenty-five years on the subject of fluxes for use in electronic manufacturing—much of it very general, much of it dealing with broad principles, and some of it based on conjecture and incomplete or faulty experimental evidence. The purpose of this paper is to review briefly the history of rosin
