Penetration of Anionic Surfactants into Skin

Skin penetration of flavonoids - influence of nonionic surfactants

These substances display strong antioxidant, free-radical-scavenging and metalchelating activity as well as many other activities [4,5]. It has been proven, that the process of lipid peroxidation can be effectively inhibited by flavonoids [6]. The skin is the first line of our defence against external agents. This organ plays a role of very effective barrier for compounds that have been applied...

Penetration of chlorhexidine into human skin.

This study evaluated a model of skin permeation to determine the depth of delivery of chlorhexidine into full-thickness excised human skin following topical application of 2% (wt/vol) aqueous chlorhexidine digluconate. Skin permeation studies were performed on full-thickness human skin using Franz diffusion cells with exposure to chlorhexidine for 2 min, 30 min, and 24 h. The concentration of c...

Interactions between Cationic Starch and Anionic Surfactants

The Penetration of Vesicant Vapors into Human Skin

Analytical methods which are accurate to about 1 per cent have been developed for the determination of small amounts (ca. 500 gamma) of bis(beta-chloroethyl)-sulfide (H), ethyl-bis(beta-chloroethyl)amine (EBA), tris(beta-chloroethyl)amine (TBA), beta-chloroethyl-benzylsulfide (benzyl-H), and beta-chloroethyl-ethylsulfide (ethyl-H). The determinations are made by micro titration of the HCl liber...

Effect of Inorganic Cations on Bactericidal Activity of Anionic Surfactants.

Voss, J. G. (Procter & Gamble Co., Cincinnati, Ohio). Effect of inorganic cations on bactericidal activity of anionic surfactants. J. Bacteriol. 86:207-211. 1963.-The bactericidal effectiveness of two alkyl benzene sulfonates and of three other types of anionic surfactants against Staphylococcus aureus is increased in the presence of low concentrations of divalent cations, especially alkaline e...
