    Sammanfattning : Cosmetic innovations are about finding high performing creative solutions that deliver into the consumer trends. The consumer trend within the cosmetic industry is currently driving a growing demand for more clean, natural skin care products with sustainable credentials. LÄS MER

  3. 2. Improving Caco-2 cell permeability assay using phospholipid covered silica beads

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Institutionen för farmaci

    Författare :Lana Faradj; [2021]
    Nyckelord :permeability; Caco-2; recovery; lipophilic; phosphatidylcholine; silica beads; peptide; plastic binding; bovine serum albumin;

    Sammanfattning : The Caco-2 cell assay is widely used for in vitro permeability measurements. However, a draw back with the assay that this study will focus on improving, is compound adsorption to the plastic material. Lipophilic compounds such as Cyclosporin A and Peptide J, that will be used in this study, tend to bind to the plastic material in the assay. LÄS MER

  4. 3. Synovial fluid components as synergistic lubricants in articular joint models

    Master-uppsats, KTH/Kemi

    Författare :Sixuan Li; [2019]
    Nyckelord :synergistic lubrication; synovial fluid; biolubrication; DPPC; hyaluronic acid; Mini-Traction Machine; macro- and microscale; profilometer;

    Sammanfattning : The excellent lubrication present within mammalian synovial joints attracted scientific interest, and some close-to-realistic models were applied to study the mechanism in vitro. In this project, the synergistic lubrication of synovial fluid was investigated by using 1,2-Dipalmitoyl-sn-glycero-3-phosphatidylcholine (DPPC), hyaluronic acid (HA), and phosphate-buffered saline (PBS buffer) to mimic the synovial fluid.

  5. 4. Lipase-based in vitro release assays for pharmaceutical lipid formulations

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

    Författare :Leonard Saffer; [2015]
    Nyckelord :phospholipase; triacyl glycerol lipase; in vitro release; fluorescein.; patent blue; pharmaceutical technology; läkemedelsteknologi; Lipid formulation; phosphatdyl choline; glycerol dioleate; Biology and Life Sciences;

    Sammanfattning : The purpose of this project was to develop and test lipase-based in vitro release (IVR) assays for model and active pharmaceutical ingredients (API) entrapped in lipid formulations based on mixtures of phosphatidylcholine (PC) and glycerol dioleate (GDO). Two dyes, Fluorescein disodium salt and Patent Blue V sodium salt, functioning as model drug compounds, were investigated separately in the PC/GDO formulation. LÄS MER

  7. 5. Efficiency of liposomal and micellar emulsifiers during homogenization

    Master-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Ellen Sunneskär; [2012]
    Nyckelord :Nanokemi; Chemistry;

    Sammanfattning : The coalescence of emulsion droplets during the homogenization process is governed by the emulsifier adsorption rate. This is in turn affected by the size and shape of the adsorbing molecule which can be dependant of the aggregation states. LÄS MER
