1. 1. Formulation development, rheological characterization, and cosmetic evaluation of gel-creams

   University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

   Author : Carl Pontén; [2024]
   Keywords : Rheology; Texture analysis; Viscometry; Semisolids; Design of Experiments; Critical Process Parameters; Critical Quality Atttibutes; Pharmaceutical Technology; Technology and Engineering;

   Abstract : Oil in water (o/w) emulsions are thermodynamically unstable systems composed of small oil droplets dispersed in a continuous aqueous phase. This means that given enough time, the two phases will separate. Pharmaceutical emulsions are used as a method of administering the Active Pharmaceutical Ingredient (API) for topical applications.

4. 3. Characterization of PLA Nanoplastics, and Their Effects on Daphnia magna

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Melinda Rydberg; [2022]
   Keywords : Polylactic acid; Polylactide; PLA; Nanoplastic; Daphnia magna; Toxicity; Polymer Technology; Chemistry; Earth and Environmental Sciences;

   Abstract : As plastic pollution in aquatic environments keeps happening it has become more and more important to learn more about nanoparticles. Bio-based and biologically degradable plastics, such as polylactic acid (PLA), are gaining popularity and it is therefore important to determine whether they break down into nanoplastics or not.

5. 4. The effects of pH and biodegradation on polymer-based granules

   University essay from Lunds universitet/Bioteknik (master)

   Author : Isak Svenningsson; [2021]
   Keywords : polymerteknik; biopolymer; bioteknik; Technology and Engineering; Biology and Life Sciences; Chemistry;

   Abstract : The use of biopolymers instead of traditional fossil fuel based and non-biodegradable polymers is seen as a positive step forward towards a more environmentally friendly future. This project investigates a granule product that is used in a dishwashing system with the aim of gaining knowledge about how it is affected by the storage in between uses and its biodegradability.

6. 5. Converting Poultry Feather Waste into Bioplastics using Green Modifying Agents

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Marc Jirström; [2021]
   Keywords : polymer technology; materials science; renewable materials; Technology and Engineering;

   Abstract : Handling of problematic waste material, and the use of fossil-based and non-biodegradable plastics are two major sustainability challenges. By developing solutions that convert waste material to bioplastics, it is possible to address both these issues. READ MORE
