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

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

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

    Sammanfattning : 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.

  3. 2. Kaolin-based coating colors with different rheological and water retention properties : Runnability on a lab-and pilot scale

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Josefine Augustsson; [2023]
    Nyckelord :rheology; runnability; barrierperformance; multibarrier; nanoclay; Speswhite; Capim NP; viscosity; shear thinning; coating performance; reologi; körbarhet; barriärprestanda; multibarriär; nanolera; Speswhite; Capim NP; viskositet; skjuvförtunning; beläggningsprestanda;

    Sammanfattning : Food packaging plays a crucial role in protecting and storing food to keep the products fresh and reduce waste. There is a need to increase the number of paper packages in the food industry to meet the growing demand. LÄS MER

  4. 3. Syn-Magmatic Deformation Structures in the Slaufrudalur Pluton, East Iceland

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Chun Hei Ho; [2023]
    Nyckelord :Granite; Iceland; magma chamber; magmatic microstructure; melt fraction; mush; pluton; rheology; strain; syn-magmatic deformation;

    Sammanfattning : Structures and deformation mechanisms of magmatic rocks are controlled by rheology. An increase in melt fraction can weaken a rock body and localises significant amount of strain. This interplay between rheology, melting and deformation in a magma reservoir, however, is not always clearly documented in literature. LÄS MER

  5. 4. Investigation of new hot melt adhesives with plasticisers based on renewable resources : Investigating the use of sustainable plasticisers in hot melt adhesives

    Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Shadi Feyzabi; [2023]
    Nyckelord :Hot melt adhesives; renewable; mineral oil; vegetable oil; rheology; viscosity; loop tack; adhesive strength; Smältlim; förnybar; mineralolja; vegetabilisk olja; reologi; viskositet; loop tack; vidhäftningsstyrka;

    Sammanfattning : Hot melt adhesives (HMA) are a class of adhesives that, unlike solvent-or waterborne counterparts, do not contain organic solvents or other carriers, and are produced and subsequently applied in a molten state. The main components of HMA are polymers, tackifying resins, and a plasticiser. LÄS MER

  7. 5. Storage period optimization of a viscous nasal spray suspension

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Lili Zsófia Domián; [2023]
    Nyckelord :Rhinocort; viscosity; rheology; thixotropy; pharmaceutical technology; Technology and Engineering;

    Sammanfattning : The number of people suffering from the unpleasant symptoms of allergic rhinitis is increasing due to environmental and other factors. This not only makes life difficult for the individual but also places a heavy burden on society, which is why treatment is needed. LÄS MER
