Tween 80 is a nonionic surfactant and emulsifier that reduces bacterial adherence and inhibits biofilm formation. Tween 80 is widely used as a co-solvent in pharmacology experiments because of its ability to enhance the solubility of compounds in the aqueous phase.

Lauryl betaine (n-Dodecyl-N) has antifungal activity and inhibits Malassezia spp. Lauryl betaine is used as a surfactant and emulsifier and is commonly used in the skin care industry.

Dihexadecyl hydrogen phosphate is a phospholipid analog that acts as an emulsifier and is commonly used in the skin care and pharmaceutical industries.

H-Leu-Leu-Ome.HCl also known as Stearamidoethyl diethylamine (SDEA) is an important compound which is a derivative of diethylamine. It is widely used in the research and production of a variety of products, including as a surfactant in cosmetics, an emulsifier in food, and a stabilizer in polymers.

Dilauryl glycerol sulfate is an auxiliary emulsifier for lipase determination.

DOPE (DOPE) is a neutral helper lipid for cationic liposomes.It is used in combination with cationic phospholipids to increase efficiency during DNA transfection studies as a non-viral method of gene delivery.

Sorbitan monolaurate, a non-ionic surfactant, is widely used as a stabilizer and emulsifier in pharmaceutical formulations, food, and cosmetic industries.

Span-85 (Sorbitan trioleate) is a synthetic non-ionic emulsifier, which is prepared by partial esterification of sorbitol or sorbitan with food grade palmitic acid. It has low viscosity and the smallest HLB value, so it has the strongest lipophilicity. It is an excellent water-in-oil (w/O) emulsifier and an O/w type auxiliary emulsifier.

Decanoic acid, 2-octyl- can be used for emulsifier or lubricant.

Polyoxyethylene Sorbitan Monostearate, an ester derived from the saturated fatty acid stearic acid (C18:0), serves multiple roles in pharmaceutical formulations, including as a surfactant, emulsifier, solubilizer, and wetting agent. As a pharmaceutical excipient—an inert substance that enhances the stability, solubility, and processability of drug formulations—it plays a crucial role in affecting the absorption, distribution, metabolism, and elimination (ADME) processes of drugs [1] [2].
