A surfactant is a "surface active agent" used in many household and industrial cleaning products. Overall, the cationic emulsions with Tween 80 appeared as a stable, efficient and serum resistant gene transfer reagent. The toxicity increases with increasing alkyl chain length and hydrophobicity of the molecule, while the influence of the poly(ethoxylate) chain length is not very pronounced except for long-chain ethoxylates exhibiting a significantly reduced ecotoxicity. However, a small but finite amount of detergent remains on the surface and contains some of the anionic surfactant that was present in solution originally applied to the surface. Nowadays, alkylphenol ethoxylates (APE) are only of limited importance for cleaning products due to voluntary or legal restrictions of their use in this application area (see below). Non-ionic surfactant levels are often around 20% of the formulation of the emulsifying wax. Various types of non-ionic surfactants, such as polyglycerol alkyl ethers, glucosyl dialkyl ethers, crownethers, ester-linked surfactants, polyoxyethylene alkyl ethers, Brij, Spans (sorbitan esters) and Tweens (Polysorbates), used for the preparation of niosomes fall into the GRAS category and are mild to use [103]. Tween surfactants were found to enhance the permeation of lidocaine through hairless mouse skin in the presence of various concentrations of propylene glycol (Sarpotdar and Zatz, 1986b). 0000076598 00000 n

non-ionic surfactant containing an 90% surfactant load. 0000002518 00000 n
Most cleaning products contain non-ionic surfactants (emulsifiers and detergents), anionic surfactants, or a mixture of both in their composition. 0000184725 00000 n

Nonionic surfactant and spreader sticker that makes herbicides and fungicides more effective. Non-toxic Surfactants. Therefore, the environmental friendliness of many of these widely used compounds needs to be reconsidered in order to be able to select the least toxic and most biodegradable surfactants for commercial use. According to their characteristics, the non-ionic surfactants can form structures in solution without charge in their polar heads. Overall, it seems that the possible reason for the prevention of aggregation of the DNA/emulsion complexes and resistance to serum is because the branched, hydrophilic polyoxyethylene chain of Tween covers a large area on the surface of emulsions like an umbrella. 0000010104 00000 n
The addition of a charged molecule to the bilayer is one of the methods used to stabilize the niosome. Anionic surfactants possess other benefits that make them ideal for certain carpet applications.
