Soft surfactant systems

Ottaviani and various coworkers have in the past often used a spin probing/ spin labeling approach to study self-assembled soft matter systems. In a recent paper they describe the complexes formed between cationic surfactants and hydrophobic ally modified anionic polymers. Analyzing the changes in dynamics as well as environment (hydrophobicity) of the long-chain fatty acid spin probe... 

Besides cooperative pathways, also tme liquid crystal templating (TLCT) and the hard template route (Section 9.3.7) have been developed for the synthesis of ordered mesoporous materials. In the case of the TLCT, a preformed surfactant liquid crystalline mesophase is loaded with the precursor for the inorganic materials (140). The nanocasting route, on the other hand, is a clearly distinct method (141). Here, no soft surfactant template is used but, instead, the pore system of an ordered mesoporous solid is used as the hard template serving as a mold for preparing varieties of new mesostructured materials, for example, metals, carbons, or transition metal oxides. 

Excellent foaming in both hard and soft water. Mild to hair and skin. Compatible in alkaline or acid-balanced surfactant systems. Great for soap applications, shampoos and conditioners. 

Although much research has been performed on these soft-template systems in past decades, it is not clear whether these surfactants really serve as tanplates or actually as growth-directing adsorbates [209]. 

This type of approach, which is also known as the soft templahng method, is typically carried out in aqueous surfactant systems such as cetyltrimethylammonium bromide (CTAB), sodium dodecylsulfate (SDS) or bis(2-ethyUiexyl) sulfosucdnate... 

The polymer characterization methods described here are quite versatile and can be applied not only to polymers, but also to soft matter systems in general (polymers, liquid crystals, colloids, membranes, surfactants, etc.) and to biological systems. The soft matter systems and biological systems have...
