Abstract Three formulations for bath liquids were developed, differing in the type of amphoteric surfactant applied. The formulations used Cocamidopropyl Betaine, Cocamidpropyl Hydroxide and newly synthesized sulfobetaine based on sweet almond oil (Oleicamidopropyl Sultaine). The molecular structure of the surfactant used in the manufactured formulations has a negatively charged sulfonate group and a positively charged quaternary nitrogen atom. Such molecular structures suggest that the functional properties of this substance are mild. Based on the research, it was found that the bath fluid containing the newly synthesized sulfobetaine based on sweet almond oil had the lowest zein number, the lowest pH increase of bovine albumin solution and the lowest ability to emulsify fatty dirt. This indicates a very low irritant effect of the tested bath liquid.

The reliability of capillary blood glucose measurements is tremendously important for patients’ care and follow-up. Some factors independent of glucose control could however affect readings during ambulatory monitoring of capillary glucose levels in patients with diabetes mellitus. We sought to evaluate the impact of three body lotions commonly used in Cameroon on different strata of glycaemia. We explored their influence over time on measured capillary glucose values. We enrolled 16 participants. Eligible individuals were adult patients with diabetes (n=12) stratified into three levels of capillary glucose values (100 ± 40 mg/dL [5.55 ± 2.22 mmol/L], 200 ± 40 mg/dL [11.1 ± 2.22 mmol/L] and 300 ± 40 mg/dL [16.65 ± 2.22 mmol/L]) and normoglycaemic individuals (n=4). We measured capillary blood glucose before application, immediately after, then 5, 30 and 60 minutes after application of sweet almond oil, corticosteroid cream and hydroquinone lotion. The measurements made on impregnated body lotion-permeated fingers were compared to that of a clean finger. We observed a significant increase (delta [95% confidence interval, CI]: 119.5% [77.4–222.1]) of capillary glucose level immediately after administration of hydroquinone-containing body lotion (p<0.001). Capillary glucose values after the use of corticoid cream and sweet almond oil was stable 5, 30 and 60 minutes after application (p=0.875 and p=0.883 respectively). In the case of the hydroquinone-containing body lotion, there was a significant difference between capillary glucose level at 5 minutes (delta [95%CI]: 81.6% [55.3–214.2]; p<0.001), 30 minutes (delta [95%CI]: 71.6% [21.8–134.6]; p<0.001) and 60 minutes (delta [95%CI]: 58.3% [2.8–133.3]; p=0.013) after application compared to the value obtained from the clean finger. We observed from our study that there were significant variations in capillary blood glucose measurements induced by the use of hydroquinone lotion.

High-performance positively-charged nanofiltration (NF) membranes have a profound significance for water softening. In this work, a novel monomer, tris(3-aminopropyl)amine (TAEA), with one tertiary amine group and three primary amine groups, was blended with trace amounts of piperazine (PIP) in aqueous solution to fabricate a positively-charged NF membrane with tunable performance. As the molecular structures of TAEA and PIP are totally different, the chemical composition and structure of the polyamine selective layer could be tailored via varying the PIP content. The resulting optimal membrane exhibited an excellent water permeability of 10.2 LMH bar−1 and a high rejection of MgCl2 (92.4%), due to the incorporation of TAEA/PIP. In addition, this TAEA NF membrane has a superior long-term stability. Thus, this work provides a facile way to prepare a positively charged membrane with an efficient water softening ability.

The mass spectra of three tetraalkylammonium bromide salts and two series of bistetraalkylammonium bromide salts, one saturated and the other unsaturated, have been studied. Substitution is the major process which occurs in the pyrolytic decomposition of these quaternary ammonium bromides when placed in the probe of the mass spectrometer. This leads to the production of a tertiary amine and an alkyl halide. The substitution reactions which occur are influenced by the proximity of the bromide anion(s) to the positively charged quaternary nitrogen centers in the crystal lattice. As well, a shorter distance between the positive nitrogen centers favors substitution reaction by means of an electron inductive effect.

The title compound, C8H11NO4S, crystallizes as a zwitterion, with the negatively charged benzenesulfonate group and the positively charged NH3+group in mutuallyparapositions. All the non-H atoms, except for one O atom of the sulfonate group, lie on a crystallographic mirror plane (Z′ = 1/2). In the crystal, the hydrogen-bonding structure is two-dimensional, propagating in thec-axis direction through a bifurcated hydrogen bond between the NH3+and the SO3−groups, and in theb-axis direction through anR22(16) ring motif involving the same functional groups. This latter hydrogen bonding is supported by offset π–π interactions [intercentroid distance = 3.8114 (4) Å].

Abstract Caffeine is a methylxanthine typically found in the Coffee Arabica L plant. Generally, caffeine is well-known as a orally administered mild stimulant of the central nervous system. However, for cosmetic purpose, caffeine is an active compound ingredient, at 7% concentration, in several anticellulite products. The efficiency of this mode of delivery is not fully understood. Hence, the aim of the study was to ascertain the effectiveness of particular carriers to release this ingredient. In so doing, we prepared six creams based upon different oils (Sesame oil, Rice oil, Walnut oil, Coconut oil, Sweet almond oil and Jojoba oil), containing 5% of caffeine, and compared the release of the substance from the obtained preparations. Initially, all of the creams were subjected to a variety of physical tests, among these being for slippage and spreadability. Furthermore, their rheological properties were evaluated. Subsequently, the creams were tested for caffeine release. In the slippage and spreadability tests, the coconut oil-based cream was revealed as having the best parameters. However, the rheological tests showed that all of the preparations had the pseudoplastic character of flowing according to the Ostwald de Waele power law model. The power low index (n) for all the preparations was from 0.2467-0.3179 at 20°C and 0.2821-0.3754 at 32°C. At 20°C, the Sesame oil-, Walnut oil-, Sweet almond oil- and Jojoba oil-based creams were thixotropic, but at 32°C, thixotropy appeared only in the Walnut oil-based creams. The release studies, conducted by way of an extracting chamber (according to Polish Pharmacoeia IX) in the Paddle Apparatus (according to Polish Pharamcopoeia IX), showed that the amount of released caffeine is the largest in the case of Jojoba oil-based cream, at 85.23% ± 0.8% (SD), and the least in the case of Coconut oil-based cream, at 62,78%± 0.87% (SD).

Two new salts, namely 2,6-diamino-4-chloropyrimidinium 2-carboxy-3-nitrobenzoate, C4H6ClN4 +·C8H4NO6 −, (I), and 2,6-diamino-4-chloropyrimidinium p-toluenesulfonate monohydrate, C4H6ClN4 +·C7H7O3S−·H2O, (II), have been synthesized and characterized by single-crystal X-ray diffraction. In both crystal structures, the N atom in the 1-position of the pyrimidine ring is protonated. In salt (I), the protonated N atom and the amino group of the pyrimidinium cation interact with the carboxylate group of the anion through N—H...O hydrogen bonds to form a heterosynthon with an R 2 2(8) ring motif. In hydrated salt (II), the presence of the water molecule prevents the formation of the familiar R 2 2(8) ring motif. Instead, an expanded ring [i.e. R 3 2(8)] is formed involving the sulfonate group, the pyrimidinium cation and the water molecule. Both salts form a supramolecular homosynthon [R 2 2(8) ring motif] through N—H...N hydrogen bonds. The molecular structures are further stabilized by π–π stacking, and C=O...π, C—H...O and C—H...Cl interactions.

Introduction: Aluminum phosphide (ALP), as an effective pesticide and a substance used for protecting rice during storage, has become one of the commonest causes of poisoning and even suicide in developing countries including Iran and India. The authors aimed to study the efficacy of sweet almond oil as an antidote in ALP toxicity. Methods: The present experimental study was conducted over 35 rats. The animals were divided into four groups: one group as the control group and three other groups which received ALP alone or ALP and sweet almond oil with different time intervals. In addition to estimating the survival rate of the animals, plasma cholinesterase activity as a possible factor affected in ALP poisoning was evaluated. Results: Treatment by intragastric irrigation of sweet almond oil resulted in significant reduction of mortality. Moreover, mean plasma cholinesterase levels were inhibited in groups receiving ALP. Conclusion: Oral sweet almond oil, if especially used immediately after poisoning with ALP, improves the survival rate.
