We demonstrate that the mass balance measurements we used are a rapid way to screen surfactants in terms of their potential to be used in enhanced oil recovery applications. Surfactant classes investigated include: alkyl(aryl) sulfonates, ethylene oxide-propylene oxide copolymers, ethoxylated alkylphenols, alkyl polyglucosides, sorbitan ester ethoxylates, alkyl alcohol propoxylated sulfate sodium salts, gemini surfactants, sulfosuccinates and organo siliconeethylene oxide-propylene oxide terpolymers. We identified several surfactants which had zero retention under the test conditions and which may therefore be suitable as enhanced oil recovery chemicals in surfactant flooding schemes. We discuss surfactant retention mechanisms on kaolinite clay and analyze surfactant structure-retention relationships for several surfactant classes.

Effect of pigment concentrations and dispersing agents on various color properties of the molded specimens, such as reflectance versus wavelength characteristics, angular dependency, K/S data, and flop index were evaluated using the CIE system with goniospectrophotometer. Surface image analysis was also conducted. Based on the above parameters, design equations were developed. The study revealed that the effective concentration of the interference pigment was 0.5% and better color characteristics were found when poly (ethylene glycol) was used as a dispersing agent.

The Impact of Fluorescent Compounds on the Change in Shade of Pastel Colored PES/Cotton Fabrics / T. Pusic in TENSIDE, SURFACTANTS, DETERGENTS, Vol. 45, N° 6/2008 (11-12/2008)

[article]  inTENSIDE, SURFACTANTS, DETERGENTS > Vol. 45, N° 6/2008 (11-12/2008) . - p. 314-319 Titre : The Impact of Fluorescent Compounds on the Change in Shade of Pastel Colored PES/Cotton Fabrics Type de document : texte imprimé Auteurs : T. Pusic, Auteur ; I. Solijacic, Auteur Année de publication : 2008 Article en page(s) : p. 314-319 Note générale : Bibliogr. Langues : Anglais (eng) Tags : Laundering  Fluorescent  whitening  agent  UV  absorber  Polyester  cotton  fabric  Pastel  shade Résumé : Functionalization of textiles in the finishing and care processes is an outstanding topic today. Ultraviolet (UV) protective properties of textiles can be improved by the implementation of fluorescent compounds in the finishing and laundering processes. The investigation described is focused on the addition of a fluorescent whitening agent (FWA) and an UV absorber (UVA) during frequent laundering of bleached and pastel colored polyester/cotton fabrics in the reference ECE detergent at 40°C. The effect of the UVA containing detergent includes improved whiteness of bleached textiles and excellent UV protection properties during multiple cycles. The bleaching performance of the FWA is similar in offering good UV protection. In the case of the pastel colored fabrics after the launderings, UV protection is excellent too, but the negative impact of the fluorescent compounds on the changes in shade is evident.

Advances in emulsion polymerization for coatings applications / Mohamed S. El-Aasser in JOURNAL OF COATINGS TECHNOLOGY (JCT), Vol. 73, N° 920 (09/2001)

[article]  inJOURNAL OF COATINGS TECHNOLOGY (JCT) > Vol. 73, N° 920 (09/2001) . - p. 51-63 Titre : Advances in emulsion polymerization for coatings applications : Latex blends and reactive surfactants Type de document : texte imprimé Auteurs : Mohamed S.

The first part of this paper focuses on an investigation of the influence of the interface between high and two Tg latex particles on the glass and surface morphologies of films obtained from model latex blends. Glass was influenced by the concentration of carboxyl groups present on the surface of the latex particles (optimal concentration for maximum gloss 3% on the high Tg particles), the degree of neutralization of these groups (higher glass with increased extent of neutralization), the type and concentration of the neutralizing base (higher gloss for stronger bases), and the presence of added surfactant (higher gloss with added surfactant). Gloss was found to be correlated with the surface smoothness of the film. The kinetics, particle size, molecular weight, and location of the reactive surfactant after polymerization, as well as the contact angle of films prepared from these latices, are examined in the second part of this paper. The polymerization rate profiles were similar to those obtained using a conventional surfactant ; however, the dependency of the rate on the number of particles was significantly lower. The amount bound increased and the molecular weight decreased with increasing surfactant concentration.

Associative polymer/latex dispersion phase diagrams. II : HASE thickeners / Edward Kostansek in JOURNAL OF COATINGS TECHNOLOGY AND RESEARCH, Vol. 2, N° 6 (04/2005)

Both bridging and depletion flocculation can occur, in addition to good particle dispersion. Dispersion phase diagrams have been developed to help visualize these interactions. The various dispersion states can have a significant effect on coating formulations and film properties. Examples of dispersion phase diagrams are presented for a model HASE anionic associative thickener and various model latexes in the presence of sodium dodecylsulfate and nonionic surfactants. The major variables affecting dispersion behavior are associative polymer concentration, latex particle size, latex surface hydrophobicity, electrolyte concentration, and surfactant concentration. The dispersion phase behavior of the HASE systems is compared to that of HEUR thickened systems reported previously. A significant difference is that much less bridging flocculation is observed in the HASE systems. In addition, nonionic surfactants induced depletion flocculation in the HASE systems but not in the HEUR systems.
