The Property of Surface Active Agents as External Antistatic Agents for Plastic Resins

Surface active agents as tumor promoters.

*TUC Centenary Institute of Occupational Health London School of Hygiene and Tropical Medicine, Keppel St., London WC1E-7HT, England. the types of promoter listed have not been demonstrated as such by animal experiments, but if a substance is a carcinogenic but not mutagenic, then it is most probably a tumor promoter. This assumes that mutagens are initiators and that promoters can induce cance...

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...

Surface Characterization of Polyester Resins Formulated with Different Crosslinking Agents

Coil Coating is an industrial process widely used to apply a paint layer to metal coil stock, in order to improve the resistance to corrosion as well as the aestetics of the surface. Three thermally cured coatings, formulated on a low Tg ispophtalic based polyester, were investigated by XPS and ToF-SIMS. A model formulation was employed for all three coatings investigated, however, the crosslin...

INTERACTION OF DNA WITH THE FOLDED AND UNFOLDED HISTONE HI IN THE PRESENCE OF SURFACE ACTIVE AGENTS

Interaction between DNA and histone H, was investigated in the presence and absence of sodium-n-dodecyl sulphate (SDS) and dodecyl trimethylammonium bromide (DTAB) at temperatures of 27 and 37?C, in 2.5 mM phosphate buffer, pH 6.4 by UV spectrophotometry, equilibriumdialysis and titration. The presence of 1.33 mM SDS caused histone H to fold and to further contact DNA. Binding data were use...
