Cationic and Ampholytic Surface Active Agents Containing Polyoxyethylene Groups

Characterization of active nanochitosan film containing natural preservative agents

Objective(s): The aim of this study was to improve different characteristics including antibacterial, antioxidant and physical properties of nanochitosan film by incorporating Mentha spicata essential oil (EO) and methanolic pomegranate peel and grape seed extracts. Methods: The determination of the chemical composition of M. spicata EO was conducted by means of gas chromatography with ma...

Surfactants - Surface Active Agents

The definition for a detergent is a cleaning agent. The main cleaning agent used in earlier days was soap. This term means a compound formed from the reaction of a fatty acid with a base such as caustic soda, forming the sodium soap of the acid. The more commonly used cleaning agent in this day and age is the synthetic detergent (SYNDET) which is a formulation such as TIDE or FAB. The essential...

Triphosphatase of Cerebral Microsomes by Surface-Active Agents, especially Polyoxyethylene Ethers: Actions of Phospholipases and a Neuraminidase

sisting of a short length of 8 mm. diam. Visking tubing knotted to form a bag, the open end being secured to a piece of glass tubing by a close-fitting rubber stopper fitted to a test tube with a side arm. The bag, after being washed with distilled water, was equilibrated with a drop of the sample solution; this drop was discarded before evacuating the tube and introducing the rest of the sampl...

Improved anti-proliferative effect of doxorubicin-containing polymer nanoparticles upon surface modification with cationic groups.

Polymer nanoparticles (PNPs) possessing a high density of drug payload have been successfully stabilized against aggregation in biological buffers after amine modification, which renders these PNPs positively charged. The resulting charge-stabilized PNPs retain their original narrow particle size distributions and well-defined spherical morphologies. This stabilization allows these PNPs to have...
