Anionic detergent

In the presence of an EOF, however, they migrate slowly towards the cathode. If now compounds are introduced into the capillary that interact with the SDS micelles, the mobility of these compounds will be influenced by the movement of the micelles to an extent that depends on the strength of this interaction. MECC is carried out using various forms of detergent anionic (e.g., SDS or Na-cholate), cationic (e.g., cetyltrimethylammonium bromide, CETB) and neutral (e.g., Triton X-100). 

Detergent molecules can stabilize the emulsion of oil in water as well as remove dirt from soiled clothes. A typical detergent is sodium dodecylsulfate (SDS), which has a formula of CH3(CH2)i0CH2SO4 Na+. In aqueous solution, SDS suspends oil or dirt by forming small aggregates of detergent anions called micelles. Propose a structure for micelles. 

Detergent, anionic, for universal use in the whole pH-range, especially wool and wool blend articles. 

Solvent containing detergent, anionic, especially for removing pitch from wood and other heavy combinations. 

This combination is comparably milder combination than that of caustic soda and hence ideally suitable for more delicate cloths and colour woven goods compensating for the slower action of the milder alkali by the addition of a detergent. Anionic products like sodium alkyl sulphates and alkyl aromatic sulphonates and non-ionics like polyethoxylated compounds are used as detergent. Sometimes mixtures of anionic and non-ionic products are used. It is possible to obtain a synergistic effect between a detergent and alkali, so that the two agents when combined increase their total activities rather than inhibit each other. Fig. 4-2 shows the syn-... 

At the same time, surfactants like alkylbenzene sulfonates remain the most widely used basis for laundry detergents. Anionics remain the main products for making detergent compositions. Some of the application aspects of relatively new types of anionics (a-olefin sulfonates, sulfocarboxylic acids, alkyl phosphates etc.), whose commercial manufacture began in the 60-ties - 70-ties of the 20 century, are described by Stache [95]. The application of conventional types of nonionics like ethoxylated alcohols or alkyl phenols is presented in [13 -14], Alkyl polyglycosides were widely used in the last 5-8 years [96]. However, the main tendency in the development of new generation detergents is the use of surfactant mixtures in their optimum composition [97, 98]. 

Capillary electro kinetic chromatography with micellar pseudophases of ionogenic detergents, anionic SDS, or cationic cetyltrimethylammonium bromide, is capable of resolving small proteins or polypeptides (Mr<6500) with minor differences in hydrophobicity resulting, e.g., from replacement of a single noniono-genic amino acid by other electroneutral amino acid residue.

Erythromycin estolate, which is a complex salt of the propionate of erythromycin (XXIV), and the detergent moiety lauryl sulphate is the only derivative of this antibiotic to produce hepatotoxicity in man [193,194]. An investigational drug erythromycin cetyl sulphate was withdrawn from trials in man when the incidence of hepatotoxic effects reached 10 to 15%. Consequently, Dujovne has examined the role of the detergent anions in these preparations on their toxic actions [193, 194].
