Generally ether carboxylates are not suitable for a syndet soap because they are waxy due to the ethylene oxide distribution. The solid ether carboxylates with a long alkyl chain and a low degree of ethoxylation have a bad foam. By use of nonethoxylated ether carboxylates, e.g., a carboxymethylated fatty acid monoethanolamide with the structure... 

FADAs are nitrogen derivatives of coconut oil synthesised from fatty acid and diethanolamine. Equimolar amounts of the two starting compounds yield water-insoluble monoethanolamides, whereas the reaction of two moles of diethanolamine with one of the acids results in water-soluble FADA possessing the typical alkyl chain distribution with the C12/C14 homologues prevailing [33]. 

Used as foam boosters in conjunction with anionic actives, these compounds contain one or two ethyl alcohol groups attached to the nitrogen atom of a long-chain alkyl amide. Monoethanolamides are secondary amides and therefore exhibit typical amide I and amide II bands at 1650 and 1560 cm" as well as an N-H stretch at 3090 cm" (Figure 10.18). The spectrum also contains a strong, broad O-H stretch centred near 3400 cm" and C-O vibrations at 1070 cm"Diethanola-mides do not exhibit any N-H features— no 3100 cm" band and only one peak between 1700 and 1500 cm" (Figure 10.19).

Alkyl ethoxy carboxylates or carboxylated nonionics, as they are also called, are well known specialty nonionics which can be used as nonionics at neutral pH or as anionics at high pH [19]. Recently amide analogs of these materials have been developed [20], called amide ether carboxylates (Fig. 16). The standard method for making carboxylated nonionics is adding sodium chloroacetate to an ethoxylated alcohol, while the amide analog is made in a similar fashion from an ethoxylated monoethanolamide. 

The most common examples of this class are the mono- and diethanolamides of linear alkyl acids. They are effective for increasing the viscosity of liquid formulations. Even normally water-insoluble products, like the monoethanolamides and isopropanolamides, can be used as viscosity improvers in the presence of large amounts of other surfactants. The monoethanolamides are widely used to stabilize the foam formed by other surfactants. Alkanolamides are also effective surfactants in their own right, although very sensitive to water hardness in the absence of other surfactants, as well as being subject to attack by acid and base. They are commonly used in shampoos and liquid soaps. ...
