This paper presents the results of the influence of surfactants in reducing friction while driving fluid in pipes. Experimental research was conducted with water-surfactant mixtures which were tested three types of these additives: anionic, cationic and nonionic surfactants. Was designed and built an experimental facility in which the test area was acrylic pipe with an inner diameter of D = 19 mm and a length of 300 D. The concentrations of surfactants in the mixtures were 150, 250, 500, 750 and 1000 ppm, added according to a pilot program that took into account the amount and type of additive added in different liquid mass fluxes. Pressure losses were compared against those obtained when flow is the same water flows through the installation. The results obtained show a reduction of up to 43.9% of the friction which is achieved with a Re = 11243 and surfactant concentrations of 250 ppm (cetyl trimethyl chloride ammonium), to which was added as a stabilizer for the micro structure of the surfactant, sodium salicylate, which applies only to the cationic type surfactants. The results are promising but left to study such issues as: the injection and recovery of surfactant, more efficient mixing, the mechanisms that lead to a reduction of friction and the effect of temperature among others.

Microemulsions have thermodynamics and stable kinetics as carriers of ?-tocopherol compounds. This study aimed to know the effect of mixtures ratio of three nonionic surfactants and stiring time on the characteristics of ?-tocopherol microemulsion, as well as to obtain the best stiring time and mixture ratio of three nonionic surfactants to produce ?-tocopherol microemulsion. This experiment used a randomized block design with two factors. The first factor is the ratio of a mixture of three nonionic surfactants with Hydrophilic-Lipophilic Balance (HLB) 14.5. The second factor is stirring time. Data were analyzed using analysis of variance and continued with BNJ test. Test the effectiveness index to determine the best treatment. The results showed that the comparison of three surfactant mixtures, stirring duration and interaction between treatments significantly affected the characteristics of ?-tocopherol microemulsion. Comparison of the mixture of three surfactants Tween 80: Span 80: Tween 20 (v / v%) HLB 14.5 consisting of F2 (89,5 : 5,5 : 5) and 4 minutes stirring time is the best treatment for the characteristics of ?-Tocopherol microemulsion. The best treatment has the characteristics of ?-tocopherol microemulsions namely transparent appearance, stable to centrifugation (4500 rpm), pH (4.5; 5.5 and 6.5) and dilution (1: 9, 1:49 and 1:99) with Turbidity index values ??are below 1 percent. Microemulsion turbidity index values ??before and after centrifugation were 0.19 percent and microemulsion turbidity at pH 4.5 and 1: 9 dilution were 0.11 percent. Keywords: microemulsion, stirring time, surfactan non ionic, ?-Tocoferol
