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.

4. 3. THE ROLE OF WATER PURITY IN EMULSIFICATION AND REMOVAL OF OIL FROM SOLID SURFACES

   Master-uppsats, Malmö universitet/Institutionen för biomedicinsk vetenskap (BMV)

   Författare :Andriani Tsompou; [2021]
   Nyckelord :ultra-pure water; detergency; detachment of oil from solid surfaces; washing; cleaning;

   Sammanfattning : Detergents are broadly used in our everyday life for cleaning and washing procedures. They are however, a source of water pollution and can have a negative effect on human health and the environment. To reduce their negative impact, a new trend of using only pure water for washing and cleaning applications is being implemented. LÄS MER

5. 4. Formulation of nanoemulsions stabilized by cellulose nanocrystals

   Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Författare :Marco Maccagno; [2020]
   Nyckelord :nanocellulose; hydroxypropyl methilcellulose; Pickering emulsions; microfluidization; drug delivery; nanocellulosa; hydroxipropylmetylcellulosa; Pickering emulsioner; microfluidization; drogleverans;

   Sammanfattning : Cellulose nanocrystals (CNCs) are bio-based nanoparticles with the ability to stabilize oil and water emulsions thanks to their intermediate wettability and nanometric size. These and other types of particle-stabilized emulsions, commonly referred to as Pickering emulsions, are of great academic and industrial interest due to their superior stability against drop coalescence compared to classical surfactant-stabilized emulsions.

7. 5. The Freeze-Thaw Stability of Mayonnaise and the Effect of Octenyl Succinic Anhydride ModifiedStarch as Emulsifier

   Magister-uppsats, Institutionen för naturvetenskap, NV

   Författare :Annica Höckergård; [2011]
   Nyckelord :;

   Sammanfattning : Mayonnaise is a very popular food emulsion, traditionally made out of water, oil, hen egg yolk and vinegar, throughout the world. However, the quality is often reduced by separation when exposed to environmental stress, such as freeze-thawing which is an issue during transportation through regions of varying climates. LÄS MER
