Coating agents

Chitosan has been investigated as a coating agent for novel formulations such as liposomes and solid lipid nanoparticles. The coating of chitosan on nanostructured systems increases the drug bioavailability owing to its permeation enhancement properties [166,167]. [Pg.49]

Apart from the above-mentioned applications, chitosan has also been used in cosmetic formulations for its water retaining and moisturizing ability due to its biocompatibility and non-antigenicity [168,169]. [Pg.49]

A practical method of prepg this compn was by the addition of a soln of the coating agent to an aq RDX slurry. Based on the quality of the product and the pellet densities obtained, a procedure of adding an acet soln of PVA + DBP to a hot w slurry of RDX, under agitation, was adopted as standard... [Pg.974]

Intermediates with wide civilian uses, for example, in the production of insecticides, pharmaceuticals, paints and lacquers, coating agents and lubricants etc. (e.g. phosgene, phosphorus oxygen chloride). [Pg.215]

TFEMA), necessary for preparation of functional water repellent paints and optical fiber coating agents. TFEMA can be manufactured by esterification of TFEA and methacrylic acid (MA) in the presence of an acid catalyst, at 70 °C. To obtain a higher conversion rate it is necessary to remove the water from the system, avoiding the formation of the thermodynamic equilibrium composition. [Pg.133]

Polymeric polyamines are also strongly adsorbed in the compact region of the electric double layer as a combination of multisite electrostatic and hydrophobic interactions. The adsorption results in masking the silanol groups and the other adsorption active sites on the capillary wall and in altering the EOF, which is lowered and in most cases reversed from cathodic to anodic. One of the most widely employed polyamine coating agents is polybrene (or hexadimetrine bromide), a linear hydrophobic polyquaternary amine polymer of the ionene type [129]. [Pg.176]
