Polysulfobetaines are zwitterionic polymers that contain a positively charged quaternary ammonium and a negatively charged sulfonate group within one constitutional repeat unit. [ 1 ] [ 2 ] In recent years, polysulfobetaines have received increasing attention owing to their good biotolerance and ultralow-fouling behavior towards surfaces.
Liquid bandage is typically a polymer dissolved in a solvent (commonly water or an alcohol), sometimes with an added antiseptic and local anesthetic, although the alcohol in some brands may serve the same purpose. [1] These products protect the wound by forming a thin film of polymer when the carrier evaporates. [1]
Wetting solutions allow efficient spreading and wetting of the surface of skin and scalp by reducing the surface tension between the hydrophobic sebum secreted by the sebaceous gland in our skin. [8] An efficient wetting solution penetrates the skin and clears any topical applications, body fluids including sebum secreted via openings of hair ...
to stabilize proteins purified protein derivative (PPD) solution used in skin testing for tuberculosis exposure as a solubilizing agent of membrane proteins for lysing mammalian cells, at a concentration of 0.05% to 0.5% v/v, generally combined with other detergents, salts and additives.
Whole bowel irrigation with polyethylene glycol and added electrolytes is used for bowel preparation before surgery or colonoscopy or for children with constipation. [6] Macrogol (with brand names such as Laxido, Movicol and Miralax) is the generic name for polyethylene glycol used as a laxative. The name may be followed by a number that ...
The exact gelling point varies depending on the properties of the gelator and the solvent, such as structure uniformity, molecular weight of the polymer, and flexibility of the polymer chain. [5] Generally, gels are prepared by firstly dissolving the soluble excipients in the solvent. [5] [3] The solution is then mixed using a mechanical ...
Hydrogel dressing is a medical dressing based on hydrogels, three-dimensional hydrophilic structure. [1] The insoluble hydrophilic structures absorb polar wound exudates and allow oxygen diffusion at the wound bed to accelerate healing. [2]
it is an ingredient in Photo-Flo, a solution used in photographic processing to prevent minerals from water being deposited on the film after drying. Apart from laboratory use, Triton X-100 can be found in several types of cleaning compounds, [ 7 ] ranging from heavy-duty industrial products to gentle detergents.
