BackgroundNano-emulsions, as non-equilibrium systems, present characteristics and properties which depend not only on composition but also on their method of preparation. To obtain better penetration, nanocosmeceuticals use nano-sized systems for the delivery of active ingredients to targeted cells. In this work, nano-emulsions composed of miglyol, rapeseed oil and salmon oil were developed as a cosmetic matrix. Measurements of different physico-chemical properties of nano-emulsions were taken according to size, electrophoretic mobility, conductivity, viscosity, turbidity, cristallization and melting point. The RHLB was calculated for each formulation in order to achieve maximum stability.ResultsBoth tween 80 and soya lecithin were found to stabilize formulations. The results showed that rapeseed oil and miglyol are the predominant parameters for determining the expression of results concerning the characterization of emulsion. Based on the mixture design, we achieved the optimal point using the following formulation: 56.5% rapessed oil, 35.5% miglyol, and 8% salmon oil. We considered this formulation to be the best as a nanocosmeceutical product due to the small size, good turbidity, and average HLB.ConclusionsThis study demonstrates the influence of formulation on the physico-chemical properties of each nano-emulsion obtained by the mixture design.

This paper presents some recent applications of Flame Atomic Absorption Spectrometry (FAAS) to different matrices and samples. The time window selected was from 2006 up to March, 2011, and several aspects related to food, biological fluids, environmental, and technological samples analyses were reported and discussed. In addition, the chemometrics application for FAAS methods development was also taken into account, as well as the use of metal tube atomizers in air/acetylene flame. Preconcentration methods coupled to FAAS were discussed, and several approaches related to speciation, flotation, ionic liquids, among others were discussed. This paper can be interesting for researchers and FAAS users in order to see the state of the art of this technique.

“…Anionic synthetic surfactant sodium dodecylsulfate (SDS) was selected for this work due to its high solubility in water and first of all because it is a well established commercial anionic synthetic surfactant [39,41]. SDS is commonly used as an ingredient in household and personal care products as well as in specialized applications [39].…”

A cathodic stripping voltammetric method for determination of As(III) using Hg electrode in water samples containing high concentrations of surfactants is described. The linear calibration plot for As(III) was achieved in the simultaneous presence of 1 mg L À1 anionic, 2 mg L À1 cationic and 2 mg L À1 nonionic surfactants for an accumulation time of 30 s in the range 1 Â 10 À8 to 1 Â 10 À5 mol L À1, the detection limit for accumulation time of 3 hours was about 2.6 Â 10 À9 mol L À1. The developed method was successfully applied to As(III) determination in five natural water samples with satisfactory results.
