    摘要： A composition is formed by compounding a first substance with a second substance. The first substance includes a bicarbonate, an acid or a combination thereof. The second substance includes a frothing agent, a coating agent or a combination thereof. The composition may be formed into coated particles or a mass of particles coated by a matrix, such as a matrix of the frothing agent. The particles or mass of particles may have more than one coating. The compound is used for preparing a stable froth on a beverage, such as a hot cup of cappuccino. The frothing agent may include not only compounds that enhance the stability of the foam but also compounds that enhance other characteristics of a desirable froth. The coating agent may be used to delay the reaction between a bicarbonate and an acid when the compound is added to water, such that a large volume of froth is produce, but undesirable flocculation, turbidity and increases in viscosity are avoided.

    摘要： A molded component or article for biomedical use is prepared from a crosslinkable non-water-soluble polymer which when crosslinked and saturated with water forms a hydrogel. The polymer is formulated as a composition containing a non-aqueous diluent in addition to the polymer, the diluent being present in a volumetric proportion that is substantially equal to the volumetric proportion of water in the hydrogel that would be formed when the polymer is crosslinked and saturated with water. The composition is cast in a mold where the composition is exposed to conditions that cause crosslinking to occur by a reaction to which the non-aqueous diluent is inert. The crosslinking reaction produces a molded non-aqueous gel which is then converted to a hydrogel by substituting an aqueous liquid such as water or physiological saline for the non-aqueous diluent. The use of a molding composition whose curing consists essentially entirely of crosslinking results in a molding process that entails little or no shrinkage, and dimensional integrity is maintained up through the formation of the hydrogel by using the non-aqueous diluent in essentially the same volumetric proportion as water in the hydrogel.
