We present the case of a patient with facial dermatitis caused by sensitization to cocamidopropyl betaine. The patient also had positive patch-test reactions to cocamidoamine, 3-(dimethylamino)propylamine, and oleamidopropyl dimethylamine. The presence of 3-(dimethylamino)propylamine as an impurity in all of these

In the past year, 1200 consecutive eczematous patients were tested with cocamidopropylbetaine 1% aq. Contact allergy was evinced in 46 subjects (3.8%), while irritant reactions (slight erythema only) were observed in 15 cases (1.25%). 30 out of 46 patients with

Since finding that all subjects with contact allergy to cocamidopropylbetaine give positive reactions to 3-dimethylaminopropylamine (DMPA), we wished to verify whether sensitization to other industrially-used tensioactives might also be due to content of DMPA as an impurity. We also investigated

Certain side-on peroxo-dicopper(II) species with particularly low ν(O-O) (710-730 cm(-1)) have been found in equilibrium with their bis-μ-oxo-dicopper(III) isomer. An issue is whether such side-on peroxo bridges are further activated for O-O cleavage. In a previous study (Liang, H.-C., et

1,1-Dimethyl-3-oxo-1,4-diazepan-1-ium chloride (1) and 1,1-dimethyl-1-carboxymethyl-3-aminopropyl ammonium hydrochloride (2) have been obtained by the reactions of 1,1-dimethyl-1,3-propylenediamine with ethyl chloroacetate and chloroacetic acid, respectively. The products have been characterized by FTIR, Raman and NMR spectroscopy. B3LYP calculations have also been carried

Inexpensive 3-(dimethylamino)-1-propylamine (DMAPA) was found to be effective in anomeric deacylation reactions giving 1-O deprotected sugars in high yield as precursors for the formation of imidate glycosyl donors. DMAPA was also found to be useful for removing excess reagents such

Cocamidopropyl betaine (CAPB) is an amphoteric surfactant commonly used in personal care products and surface cleaners. Patch testing with commercially-available CAPB has yielded occasional reactions indicative of allergic contact dermatitis. To determine if subjects with previous positive patch tests would

It is commonly held that certain leukocyte sub-populations adhere selectively to histamine-serum albumin conjugates. A large number of soluble histamine, ethylamine and dimethylaminopropylamine conjugates were synthesised and labelled with fluorescein isothiocyanate (FITC). Although a number of conjugates bound to mononuclear
