In order to keep emulsions stable, emulsifying agents are added. The following is a list of emulsifier characteristics: 1. They are compounds that have both a hydrophilic (polar) and hydrophobic end … Zobacz więcej Several theories are relevant in a single emulsion system. For example, reducing the interfacial tension is critical during the earliest stages of emulsion formation. However, the development of a protective molecular … Zobacz więcej Witryna1. Rate of Dissolution (Kd) -the rate at which the drug goes into solution 2. Rate of Precipitation (Kp) -how much of the drug is going to come out Thus the equilibrium solubility of a drug is controlled by the relative rate constants of the two processes indicated Kd ≤ Kp Emulsions without emulsifier
