    Abstract : Tactile perception is considered an important contributor to the overall consumer experience of a product. However, what physical properties that create the specifics of tactile perception, are still not completely understood. READ MORE

  2. 2. Skin barrier responses to moisturizers

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Izabela Buraczewska; Uppsala universitet.; [2008]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; skin barrier function; moisturizers; long-term treatment; transepidermal water loss; gene expression; skin pH; lipids; urea; MEDICINE Dermatology and venerology; clinical genetics; internal medicine Dermatology and venerology; MEDICIN Dermatologi och venerologi; klinisk genetik; invärtesmedicin Dermatologi och venerologi;

    Abstract : Moisturizers are used in various types of dry skin disorders, but also by people with healthy skin. It is not unusual that use of moisturizers is continued for weeks, months, or even years. READ MORE

  3. 3. Lipid bilayers versus monolayers- Sponge phases and skin lipid domains

    University dissertation from Food Technology, Lund University

    Author : Katarina Ekelund; Lunds universitet.; Lund University.; [2000]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fatty acids; Langmuir-Blodgett films; AFM; domains; stratum corneum; bilayer curvature; lipids; glycerol monooleate; phase behaviour; sponge phase; L3 phase; Livsmedelsteknik; cholesterol; Food and drink technology;

    Abstract : The L3, or sponge, phase is a thermodynamically stable isotropic liquid consisting of a surfactant membrane in aqueous solution. A solvent induced L3 phase is shown in systems of solvent, monoolein and water. READ MORE

  4. 4. On the Phase Behaviour of Lipids with Respect to Skin Barrier Function

    University dissertation from Food Technology, Engineering and Nutrition, Lund University

    Author : Johan Engblom; [1996]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; glycerol monooleate; cholesterol; fatty acids; azone; bicontinuous mesophases; phase behaviour; lipid polymorphism; Stratum corneum; skin penetration; X-ray; Food and drink technology; Livsmedelsteknik;

    Abstract : The aim of this thesis has been to provide further understanding of skin barrier function from a chemical point of view. The main barrier is known to be located in the outermost layer of the skin, stratum corneum, composed of cornified flattened cells in conjunction with an extracellular lipid-water matrix. READ MORE

  5. 5. Tactile Perception - Role of Physical Properties

    University dissertation from Stockholm : KTH

    Author : Lisa Skedung; KTH.; [2010]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Finger Friction; Skin Friction; Paper Friction; Friction Coefficient; Piezoelectric Force Sensor; Skin Tribology; Biotribology; Soft Tribology; Surface Roughness; Profilometry; Coated Paper; Uncoated Paper; Printing Paper; Magazine Paper; Tactile Perception; Psychophysics; Multidimensional Scaling; Magnitude Estimation; Paper Coarseness; Thermal Conductivity; X-ray Photoelectron Spectroscopy.; MEDICINE Chemistry; MEDICIN Kemi;

    Abstract : The aim of this thesis is to interconnect human tactile perception with various physical properties of materials. Tactile perception necessitates contact and relative motion between the skin and the surfaces of interest. READ MORE
