This effect enables dark hair to be dyed in various bright colors. In order to enhance this bleaching effect, the concentration of either the alkalizing or oxidizing agent in the hair color base is generally increased. However, this method causes chemical damage to the hair. With the aim of finding methods to obtain an improved bleaching effect without increasing the amount of bleaching ingredients, the authors investigated the permeation mechanism. Cationic bases showed the highest bleaching effect and allowed greater penetration, permitting bleaching ingredients to enter the cortex of the hair more easily and diffuse more quickly. In addition, the molar ratios of higher alcohol (A) to cationic surfactant (C) as a function of the bleaching effect were also evaluated. The results showed an optimum range for this A/C ratio. The smoothness of the hair was also evaluated, revealing an optimum range for the A/C ratio. Based on these findings, a product with an A/C ratio that maximizes the bleaching effect and the smoothness of the hair was successfully developed. Comparison of this newly developed product with a conventional product verified that the new product has a greater bleaching effect and gives a beautiful depth of color while maintaining the silky smoothness of the texture of the hair.

The surface tension measurements revealed that aggregates are formed, and dynamic light scattering (DLS) measurements suggested the aggregates are vesicles. The size and morphology were observed by transmission electron microscopy (TEM). The vesicle formation was further confirmed by dye entrapment studies.

The structures of intermediate and product were confirmed by infrared spectroscopy and 1H nuclear magnetic resonance spectroscopy. Surface activity and wetting ability of the surfactant were also investigated. The results show that the prepared surfactant exhibited excellent surface activity reducing the equilibrium surface tension of water to a minimum value of approximate 21.8 mN · m–1.

Langues : Anglais (eng) Catégories : Surfactants Tags : 'Surfactant anionique' 'Dérivé glycine' 'Réaction amidation' Index. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : Sodium sarcosinate, an anionic surfactant, is known as a methylated glycine derivative, that is synthesized in a one-step amidation reaction. In this work, to find out the best conditions, several experiments carried out. So, the highest yield was obtained at (30±3) °C, by gradual addition of sodium monochloro acetate to methylamine solution. The total reaction time is 6 hours. Based on data, and the plots of kinetics of the reaction, a second-order reaction equation was suggested for this synthesis reaction. The rate constant (?), and the regression coefficient (R2) were found as 0.0085 and 0.0934, respectively, which were in the best agreement with second-order reactions. According to the results, these data were applied for scale up laboratory to pilot phase. In addition, an industrial plant was suggested and designed.

These observations remain unaltered in the presence of externally added surfactants. The effect of the cationic surfactant (i.e., N-cetylpyridinium chloride [CPC]), anionic surfactant (i.e., sodium dodecyl sulphate [SDS]) and neutral surfactant (i.e., Triton X-100 [TX-100]) has been studied. CPC inhibits the reactions, whereas SDS and TX-100 accelerate the reaction to different extents. Observed effects have been justified by considering the hydrophobic and electrostatic interaction between the surfactants and reactants. SDS and TX-100 can be used as catalysts in the production of acetaldehyde from ethanol. Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=15548
