11. On the phase behavior of triglyceride/ethanol/water-systems
University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)Abstract : For personnel working in areas where hand disinfection is important, skin irritation on hands is a large and real problem. A solution may be a hand cream, containing ethanol, with moisturizing properties by using a Pickering emulsion. However, the effect of ethanol on a Pickering emulsion is unknown. READ MORE

12. Phase Behavior of Water and Cyclodextrin Systems
University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)Abstract : The effect of water on α-, β-, and γ-cyclodextrins (CD) was investigated using sorption calorimetry, differential scanning calorimetry and dynamic vapor sorption in order to understand the phase behavior and to create phase diagrams. By relating earlier X-ray diffraction patterns of cyclodextrins equilibrated over saturated salt solutions and literature regarding the cyclodextrin hydrates to the sorption calorimetry and vapor sorption results, it proved possible to determine several distinct cyclodextrin structures depending on the cyclodextrin/water composition.

14. Suitability of Spray Dried Powder containing Lipids for Inhalation Formulation based on Fine Particle Fraction and Particle Size Distribution
University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)Abstract : The aim of this master thesis is to provide an indication of the suitability, or otherwise usage, of spray-drying for production of powder aimed for inhalation formulation and comparing the characteristics of the product, with and without lipids. Lipids have a proven effect of delaying release of active drug substances in the cardiovascular system and pulmonary systemic delivery has a number of advantages, chiefly among them being bypassing the first pass metabolism.

15. Formulation and characterization of liposomal spray dried powders intended for inhalation
University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)Abstract : This master thesis has evaluated the possible use of a spray dryer to produce powders suitable for use as inhalants and whether the addition of liposomes to the solution to be spray dried would improve the properties of the powder. The powders created consisted of Lysozyme as model drug, Lactose as filler and stabilizer, and different types of phospholipids to create liposomes using an ethanol injection method. READ MORE
