Surfactant classification according to the composition of their head: non-ionic, anionic, cationic, amphoteric. Most commonly, surfactants are classified according to polar head group. A non-ionic surfactant has no charged groups in its head. The head of an ionic surfactant carries a net positive, or negative, charge.
Sodium lauryl sulfate is a widely used in the pharmaceutical field as an ionic solubilizer and emulsifier that is suitable for applications in liquid dispersions, solutions, emulsions and micro emulsions, tablets, foams and semi-solids such as creams, lotions and gels. [16]
Although they are attracted to oil, and an oil-in-water emulsion forms, the emulsion will not stay stable for long and will eventually coalesce. [10] With the addition of a polyelectrolyte, electrostatic forces between the oil and water interface are formed and the surfactant begins to act as an “anchor” for the polyelectrolyte, stabilizing ...
Tannins – color, emulsifier, stabiliser, thickener; Tansy – Tara gum – thickener, vegetable gum, stabilizer; Tarragon (Artemisia dracunculus) – Tartaric acid esters of mono- and diglycerides of fatty acids – emulsifier; Tartrazine – color (yellow and orange) (FDA: FD&C Yellow #5) Tea oil/Camellia oil – widely used in southern ...
The name "emulsion polymerization" is a misnomer that arises from a historical misconception. Rather than occurring in emulsion droplets, polymerization takes place in the latex/colloid particles that form spontaneously in the first few minutes of the process. These latex particles are typically 100 nm in size, and are made of many individual ...
Polysorbate 80 is a surfactant and solubilizer used in a variety of oral and topical pharmaceutical products.. Polysorbate 80 is also an excipient that is used to stabilize aqueous formulations of medications for parenteral administration, and used as an emulsifier in the making of the antiarrhythmic amiodarone. [9]
Most frequently, it is used as an emulsifier and cationic agent in ophthalmic nanoemulsions in products like Cationorm and Retaine MGD. Due to its high lipophilicity , cetalkonium chloride is strongly associated to oil nanodroplets at the oil/water interface in oil-in-water emulsions, hence providing a positive charge at the surface of the oil ...
