The main qualities of fibers and dressings as wound care products include that they are bacteriostatic, anti-viral, fungistatic, non-toxic, high absorbent, non-allergic, breathable, haemostatic, biocompatible, and manipulatable to incorporate medications, with good mechanical properties Figure 3. Pharmaceutical industries use purified alginates as stabilizer in solution and dispersion of solid substances.
Edible films were also prepared as emulsifiable alginate with new barrier properties and good mechanical properties also allowing protecting encapsulated active substances Journal of Applied Polymer Science Basically, intoxication with alginate occurs through inhalation of the powder by patient and practitioner, accidental intake by the patient, and absorption by oral mucosa in the cases of repeated impression procedures Braga et al.
Alginato de sódio
Comparison of gels of different chemical composition. Food Hydrocolloids 25 Antimicrobial packaging with lactic acid bacteria incorporated in alginate film matrix allows to control the growth of food-borne pathogens in ready-to-eat food Cooking or warming breaded foods in a microwave oven causes a lack of crunchiness. A study of the constitution of alginic acid by partial acid hydrolysis.
Therefore, the present work aimed at assessing the cytotoxicity of dental alginates in cell cultures. A film of alginate plus salt as an edible susceptor in microwaveable food.
The use of cell cultures has been widely employed as part of a series of recommended tests to assess the biological behaviour of materials put in contact with human tissues Estrela, ; Jorge et al.
Firstly, the chemical composition is recalled and the slginato techniques used for characterization are cited.
The absorption characteristics of alginate wound dressings were analyzed and it was found that alginate wound dressings absorb a large quantity of liquid into the fiber structure, in addition to those held between the fibers in the textile structure. The brown algae Phaeophyceae such as Fucus, Laminaria, Ascophyllum contain large amounts of alginate in their cell walls 1,2.
Cytotoxicity evaluation of Activ GP and Resilon cones in vitro. Incorporation of garlic oil, a natural antibacterial agent gives good edible film Cytotoxicity of titanium dioxide nanoparticles in mouse fibroblast cells. Sorban calcium alginate fibre fressings in footcare.
Acta Chemica Scandinavica 23 Porto Alegre, 36 2: Haemostasis and tissue repair is an important domain of development of alginate produced as thin filament in the dle form.

Due to the process in aqueous and mild conditions, it is also easy to prepare fibers for enzyme immobilization or as support for bioactive molecules Calle Batalla del 5 de Mayo, esquina Fuerte de Loreto. Ion binding on polyuronates-Alginate and pectin. Polysaccharide- based hydrogels in tissue engineering, in Polysacharides.
El objetivo de este estudio fue evaluar la citotoxicidad de los alginatos para aplicaciones dentales. In that view, a film of alginate gel with high salt concentration was used as an edible susceptor.

Fourteen different alginates were assessed: At end, it is important to mention the recent synthesis of well defined new biohybrid glycopolymers having guluronic oligomers grafted on a hydrophilic backbone giving also gels in the presence slginato calcium counterions.
In addition, alginate wound dressings also have novel hemostatic and antimicrobial properties as well as the ability to promote wound healing.
In this domain, alginates are also widely alginayo as additives capable of viscosifying, stabilizing, emulsifying solutions The gel-forming process for alginate fibers and the gelling behavior of various types of alginate fibers were described. Alginate applications, alginate composition, alginate fibers, alginate properties, Ca-gelation.
