Detergents and cleansers

The composition of a modern heavy duty detergent (HDD) may be very complex, containing different types of substances. Table 3.3 shows the typical major components of detergents and cleansers [4]. 

Finishing liquid detergents and cleansers typically employ short-chain alkylbenzene sulfonates such as toluene sulfonate or cumene sulfonate, which, because of their hydrotropic properties, ensure the solubility of other detergent components in the aqueous environment. Analysis of hydrotropic compounds is performed with ion-pair chromatography. The compounds are eluted in order of increasing alkyl substitution. As revealed by Fig. 8-56, these compounds can be determined directly in the finished product... 

The composition of a detergent or cleaner may be very complex, containing different types of substances. Tables 8.3 and 8.4 show the typical major components of detergents and cleansers for household and institutional applications [71]. In addition to this the components themselves are mixtures as they are usually of technical grade. This makes the description and interpretation of the interfacial processes even more complex. 

The global household detergent and cleanser market had a value in 2008 of 86,565 Mio . 

Indirect polarographic methods are used to determine nitrilotriacetic acid (NTA) and other polyamino acids, e.g., EDTA (auxiliary agents for detergents and cleansers). The methods are based on the formation of stable heavy metal complexes with polarographic properties that are different from those of the acids. Bismuth and cadmium salts are used, added in small excess to the sample. For determination of the acids, use is made of the current signals that are caused either by the excess... 

The finishing of liquid detergents and cleansers typically employs short-chain alkylbenzene sulfonates such as toluene sulfonate or cumene sulfonate that. 

A substantially faster alternative is solid-phase microextraction (SPME). In recent years, the SPME technique has been used in our laboratory as an effective method for analyzing fragrance compounds in cosmetic products, fragrant splashes, detergents, and cleansers. It is an innovative, fully solvent-free sample preparation method and represents an excellent alternative to the conventional...
