  1. 6. Deacetylated Hyaluronan : Exploration of deacetylation techniques for hyaluronan (oligo and polysaccharides)

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Sima Mardini; Hanna Björk; Marcus Möller; Carl Lagergren; Oscar Samuelsson; [2023]
    Keywords : hyaluronic acid; deacetylated hyaluronan; N-deacetylation; re-acetylation; hydrogels;

    Abstract : Hyaluronic acid is an organic polysaccharide with a wide range of uses in medical and cosmetic industries due to its physiological properties. Crosslinked hyaluronic acid is a commonly used filler agent because of its water retention capabilities. N-deacetylation can be performed to enable new derivatives of hyaluronic acid. READ MORE

  3. 7. The effect of temperature on the chemical stability of Vitamin C in a cosmetic product – Development of an HPLC-method for quantitative analysis

    University essay from KTH/Tillämpad fysikalisk kemi

    Author : Sofia Thuresson; [2022]
    Keywords : Vitamin C; HPLC; Stability; Degradation; Antioxidant; Vitamin C; HPLC; Stabilitet; Nedbrytning; Antioxidant;

    Abstract : Vitamin C är en populär ingrediens i hudvårdsprodukter, bland annat på grund av dess positiva effekter på kollagen-produktionen i huden och dess antioxidativa egenskaper. Dessvärre är vitamin C en känslig ingrediens som lätt bryts ned av ljus, syre, hög temperatur eller fel pH-värde. READ MORE

  4. 8. Study of yield variation in a pharmaceutical manufacturing process and optimization of purification subsection : By a design of experiments study of the production parameters and a laboratory study of the purification step

    Abstract : The product R1-MR2E is an ester formed from an esterification of a carboxylic acid and an alcohol at Cambrex Karlskoga AB. The production of the intermediate R1-MR2E is a large-scale production and there are two main objectives and two sub-objectives that this project aims to study of the manufacturing. READ MORE

  5. 9. Analysis of non-volatile chemicals from graminoid plants

    University essay from KTH/Kemi

    Author : Jakob Flygar; [2022]
    Keywords : Liquid Chromatography; Cyperus Rotundus; Panicum Repens; Malaria; Mass spectrometry; Vätskekromatografi; Cyperus Rotundus; Panicum Repens; Malaria; Masspektrometri;

    Abstract : Syftet med denna studie var att utveckla en separations- och analysmetod för identifiering av icke-volatila substanser från strån och rötter av de gräsliknande växterna Cyperus rotundus och Panicum repens. För analysen användes högpresterande vätskekromatografi (HPLC) och ultrahögpresterande vätskekromatografi (UHPLC) med en opolär stationär fas (RP-HPLC) med ultraviolett ljus (UV) och elektrosprej masspektrometri detektion (ESI-MS).
