Foaming Agents

Foaming agents refer to a type of surfactant that can reduce the surface tension of water to form foam, so that the air bubbles in the aerated flotation slurry can adhere to the selectively floating mineral particles. CD Formulation provides customers with various excipient molecules. Our pharmacies or other professional researchers and experimenters are constantly developing new product solutions. We can customize foaming agents for customers, and can also provide customers with drug research and development solutions.

About Foaming Agents

Foaming agents refer to a type of surfactant that can reduce the surface tension of water to form foam, so that the air bubbles in the aerated flotation slurry can adhere to the selectively floating mineral particles. The molecular structure of foaming agents is similar to that of collectors, most of which are heteropolar molecular surface active substances composed of polar groups and non-polar groups. One end of the molecule is a polar group, and the other end is a non-polar group. The polar group of the collector is close to solids (minerals), and the non-polar group is close to air. The polar group of the foaming agent is hydrophilic, and the non-polar group is air-loving. Oriented arrangement at the water-gas interface reduces the surface tension of water, so it has a foaming effect. Among them, there are non-ionic and ionic compounds. Among them, the non-ionic indicates that the variety, function and effect of the active foaming agent are dominant. Non-ionic foaming agents generally do not have collecting properties, while ionic foaming agents often have both collecting properties.

Commonly Used Foaming Agents

Heptafluoropropane is a liquefied gas. In a container under its own vapor pressure, it is a liquid at room temperature, and when exposed to atmospheric pressure, it is a gas at room temperature. The liquid is colorless and odorless. The gas has a slight ether odor at high concentrations. Heptafluoropropane is non-corrosive, non-irritating, and non-flammable.

Preparation Applications

Heptafluoropropane contains only carbon, fluorine and hydrogen atoms in its molecule, so it is classified as a hydrofluoroalkane (HFC) propellant. The molecule does not contain chlorine atoms, so it will neither affect the ozone layer nor affect the earth's greenhouse effect. Heptafluoropropane is an ideal alternative to Freon series propellants for metered inhalation aerosols (MDIs). Although its vapor pressure is lower than tetrafluoroethane and dichlorodifluoromethane, it is higher than most propellants used for metered inhalation aerosols. Similar to tetrafluoroethane, heptafluoropropane has poor solubility for some active drugs in the formulation of metered inhalation aerosol formulations, or some commonly used surfactants or dispersants.
