Diethanol amide fatty acid

Non-ionic surfactants containing an amide group This group of non-ionic surfactants comprises different sub-groups, such as polyethoxylated amides, fatty acid diethanol amides, aminosu-gars and dialkyl disugar amides (gemini surfactants). 

Therefore, a C13-AE, a cationic (quaternary ammonium) surfactant (quat), an amphoteric Ci2-alkylamido betaine, and the non-ionic fatty acid diethanol amide (FADA) as presented with their FIA-MS spectra in Fig. 2.5.12(a)-(d) were analysed as pure blends and as mixtures always obtained from two blends in FIA-MS multiple ion detection mode (MID). Mixtures as well as pure blends contained identical concentrations of surfactant homologues. For AE quantitation the mass traces of all A m/z 44 equally spaced homologues (m/z 306-966) of the C13-AE were recorded. The cationic (quaternary ammonium) surfactant, the amphoteric Ci2-alkylamido betaine, and the non-ionic FADA were quantified recording the mass traces at m/z 214 and 228, or 184, 212, 240, 268, 285, 296, 313, 324 and 341, or 232,260, 288, 316 and 344, respectively. 

Fatty acid and unsaturated fatty acid mono- and diethanolamides Fatty acid mono- (FAMA) and diethanol amides (FADA) with the general formula (C,32n+1-C(0)N(HyCH2-CH2-0H)2 x = l or 0) are presented with their general structural formulae in Fig. 2.9.28(a) and (b). These surfactants have found a widespread application in household and personal care formulations because of their quite good... 

The MS analysis using ESI was applied for the determination of an unknown surfactant compound contained in an extract of a shampoo formulation [44]. MS leading to sequential product ions helped to identify the constituents. The MS4 experiments together with other spectral observations confirmed the hypothesis that the unknown compound was a N-( 2-aminoethyl) fatty acid amide with the general formula R-C(0)-NH(CH2-CH2-N)R/R,/. An authentic sample of the proposed laury ampho mono acetate (LAMA) (R = -CH2-CH2-OH and R" = -CH2-CH2-COOH) that was available led to the same [M + H]+ parent ion at m/z 345. The fragmentation that could be observed under ESI-FIA-MS-MS(+) conditions resulted in an intensive examination of amide surfactants. However, only two of them—lauryl diethanol amide ([M + H]+ m/z 288), a non-ionic surfactant and laurylamido-(3-propyl betaine ([M + H]+ m/z 343)—...

Polymers obtained from natural products or from their immediate derivatives such as vegetable oil, modified epoxidised oils, transesterified oils, heated oil, monoglyceride and diethanol amide or fatty acids of vegetable oils, cashew nut seed liquid (CNSL) and derivatised polymers, are bioderived polymers. " The details of vegetable oil-based polymers are the subject matter of this book and hence are discussed in detail in subsequent chapters. 

Preparation of poly (ester amide) from diethanol amide of fatty acid... 

In most of the reports on this process, the azeotropic technique was used for the preparation of poly(ester amide) resins, where the diethanol amide of the fatty acids, with dibasic acids or anhydrides, is heated in refluxing xylene using different types of catalysts such as NaOMe and phosphoric acid. It has been found that the technique described above produces a good yield of resin in a much shorter time. In this technique, the xylene used during the resinification reaction is automatically removed from the product by evaporation under the usual reaction conditions. 

A few hyperbranched poly(ester amide)s have been prepared using a similar A2 + BBV approach, in which phthalic anhydride or maleic anhydride as an A2 monomer and diethanol amine as a BB 2 monomer were used. The polycondensation polymerisation technique is used to prepare the polymers. These poly(ester amide)s are modified by long alkyl chain (fatty acids) end groups. The dielectric properties of the modified polymers were investigated over a range of frequencies and temperatures. No relaxation peak was noticed in the dielectric spectrum at different temperatures. Castor oil and Mesua ferrea L. seed oil-based hyperbranched poly(ester amide)s are prepared using diethanol fatty amide of the oils with different types of anhydrides and dibasic acids with or without diethanolamine. 

Different pathways based on different raw material sources are used in technical processes. The original route as described in patents by W. Krichevsky in 1937 is based on the direct condensation of fatty acids with alkanolamines in excess. For the synthesis of diethanol amides, the reaction scheme is shown as follows ...

Fatty alcohol, fatty acid diethanol amides, and amine oxides are known to stabilize foam of anionic surfactants like SLS [75,76]. Lauryl alcohol efficiency is reported to be due to a reduction in liquid drainage [16], an increase in surface viscosity [77], or a decrease in the CMC of the anionic surfactant [76]. Fatty acids are known for their foam-stabilizing properties in shaving foams, for example. Their efficiency is pH dependent. Foam-stabilizing properties of mixtures of fatty acids and esters were mentioned in a patent literature [78].
