Increased stability is conferred on oil-in-water emulsions of perfluorocarbons by addition of a minor (0.1-5% w/v) amount of a fluorinated compound of higher bailing point than the perfluoracarbon being emulsified. The added fluorinated compound is preferably a perfluorinated saturated polycyclic hydrocarbon. The most preferred additive is perfluoroperhydrofluoranthene.

Storage stable fluorocarbon emulsions having a continuous aqueous phase and a discontinuous fluorocarbon phase, in which the fluorocarbon phase comprises a major amount of a first fluorocarbon or fluorocarbon mixture, and a minor amount of a second fluorocarbon or fluorocarbon mixture, in which the second fluorocarbon has a molecular weight greater than that of the first fluorocarbon and the second fluorocarbon includes a lipophilic moiety in its structure, whereby the second fluorocarbon serves to promote particle size stability in the emulsion while simultaneously providing favorably short organ retention times when administered to animals
in vivo.

A packaged gas-solubilized product is described. The gas-solubilized product contains a first gas with a first pressure. The product is placed into a flexible inner container made of a gas-impermeable material. The inner container is hermetically disposed inside an outer container. A space formed between the inner and the outer containers is charged with a second gas with an initial charging pressure. The initial charging pressure is higher than the pressure of the first gas contained in the product. Additionally, a product dispenser in a fluid connection with the product contained in the internal container is included. The present invention also provides a method of packaging a gas-solubilized product to prevent a change in the concentration of the gas dissolved in the product during its storage and dispensing.

The present invention provides a method of making a FC emulsion. The method comprises mixing an FC immiscible hydrophilic liquid and a solid emulsifying agent by agitation at a temperature elevated above the phase transition temperature of the emulsifying agent and below the boiling temperature of the FC immiscible hydrophilic liquid, and adding FC to the mixture of step (a) and agitating at the elevated temperature to disperse droplets of FC in the FC immiscible hydrophilic liquid to form the FC emulsion. The invention also provides another method of making an FC emulsion, which does not require a solid emulsifying agent. The method comprises mixing an FC immiscible hydrophilic liquid and an emulsifying agent to form a first mixture; mixing a stabilizing agent with the first mixture to form a second mixture; and mixing FC with the second mixture to form a third mixture to disperse droplets of FC in the FC immiscible hydrophilic liquid and to form the FC emulsion, wherein the stabilizing agent reduces ability of the droplets to move within a continuous phase of the FC emulsion.
本发明提供了一种制造 FC 乳液的方法。该方法包括在高于乳化剂相变温度和低于 FC 不溶亲水液体沸腾温度的温度下,通过搅拌将 FC 不溶亲水液体和固体乳化剂混合,并在步骤(a)的混合物中加入 FC,在升高的温度下搅拌,使 FC 液滴分散在 FC 不溶亲水液体中,形成 FC 乳液。本发明还提供了另一种不需要固体乳化剂的 FC 乳液制造方法。该方法包括混合 FC 不溶性亲水液体和乳化剂以形成第一混合物;将稳定剂与第一混合物混合以形成第二混合物;以及将 FC 与第二混合物混合以形成第三混合物,从而将 FC 液滴分散在 FC 不溶性亲水液体中并形成 FC 乳液,其中稳定剂可降低液滴在 FC 乳液连续相内的移动能力。
