Alginate hydrogel is a common biomaterial for bio-fabrication of scaffolds and tissue regeneration. [18] Covalent bonding of thiol groups to alginate improves in-situ gelling and mucoadhesive properties; the thiolated polymer forms disulfide bonds within its polymeric network and with cysteine-rich subdomains of the mucus layer.

However, alginate has a poor tear strength and it cannot be used for bite registration against a Polyvinyl siloxane (PVS) impression as poor articulation will result from the lack of surface detail. For a PVS impression, bite registration should be taken with a PVS material or an alginate substitute. [19]
Calcium alginate is a water-insoluble, gelatinous, cream-coloured substance that can be created through the addition of aqueous calcium chloride to aqueous sodium alginate. Calcium alginate is also used for entrapment of enzymes and forming artificial seeds in plant tissue culture.
Babassu oil – similar to, and used as a substitute for coconut oil. Baking powder – leavening agent; includes acid and base; Baking soda – food base; Balm, lemon – Balm oil – Balsam of Peru – used in food and drink for flavoring; Barberry – Barley flour – Basil (Ocimum basilicum) – Basil extract – Bay leaves – Beeswax ...
Carrageenan has specific uses in an array of agricultural products, and public comments reported that potential substitutes do not adequately replicate the functions of carrageenan across the broad scope of use. Therefore, carrageenan continues to meet the OFPA criteria for inclusion on the National List. [31]
Other composites suitable for use in artificial bone are those using alginate, a biopolymer known for its scaffold-forming properties. Uses for alginate in composites include chitosan composites for bone tissue repair, bioglass composites for repairing or replacing defective or diseased bone, or ceramic-collagen composites for bone regeneration ...
With the price of eggs rising and shortages being reported at grocery stores around the U.S., hungry consumers may need to look outside the box, or shell, for alternatives. The average price of a ...
Sodium carbonate is used by the brick industry as a wetting agent to reduce the amount of water needed to extrude the clay. In casting, it is referred to as "bonding agent" and is used to allow wet alginate to adhere to gelled alginate. Sodium carbonate is used in toothpastes, where it acts as a foaming agent and an abrasive, and to temporarily ...
