Tension superficielleIndex. décimale : 667.9 Revêtements et enduits Résumé : Surface control additives (SCAs), or surfactants, can obstruct the wetting of liquid films on lyophilic surfaces even though they lower surface tension. In this work, this unusual behavior was used to decrease the widths of printed organic and nanoparticle lines on different homogeneous surfaces. A decrease in line width accompanied a change in its cross section. The ability of a SCA to decrease the line width was correlated with contact angle but not the surface tension of the solution. Line refinement was consequently attributed to an increase in contact angle. Because there were no reports that surfactants increased contact angles, the mechanisms to increase contact angle were discussed in static and dynamic terms. First, Owens and Wendt’s theory revealed that contact angle changes depended on SCA-induced modification of polar and dispersive interfacial components. However, a definitive increase in contact angle could not be deduced from this theory alone. Second, the effect of solutal Marangoni forces induced by the SCAs on contact angle was discussed by considering the wetting behaviors of binary solvents. SCA concentration dependence of surface tension at higher than the initial SCA concentration correlated well with the ability of the SCA to decrease line width.

Tension superficielleIndex. décimale : 668.5 Parfums et cosmétiques Résumé : The search for innovative and sustainable products that are less damaging to the skin is a matter of foremost importance in the cosmetics area. Chemical surfactants are widely used in cosmetic formulations, however, they have harmful effects, such as allergic reactions and skin irritations, therefore, it is evident that chemical surfactants need to be replaced by more sustainable compounds that present fewer or no negative effect on skin health. Biosurfactants have shown great potential, presenting advantages such as biodegradability, low toxicity, skin compatibility, increased protection and moisturizing effects. Rhamnolipids (RLs) are biosurfactants produced by some bacteria, mainly . Because of the presence of hydrophilic and hydrophobic groups in the same molecule, RLs present interesting emulsifying and surfactant properties, making them a suitable alternative to chemical surfactants in cosmetic formulations. In the current study, the properties of the biosurfactant produced by Apoena Biotech were investigated through surface tension tests, CMC, foam formation and stability, antioxidant potential and makeup removal. It was found that RL is a potential substitute or co-surfactant for chemical surfactants. In addition, its antioxidant activity makes it a multifunctional active that can provide benefits to the skin, besides its surfactant’s properties.

Tension superficielleIndex. décimale : 667.9 Revêtements et enduits Résumé : A stratifying coating based on chlorinated rubber and epoxy resin paint blend has been prepared. Chlorinated rubber is pigmented with rutile grade titanium dioxide and epoxy resin is pigmented with red iron oxide. Different types of curing agents on the stratification behavior of pigmented chlorinated rubber/epoxy resin has been studied. Surface tension as well as its polar & disperse component for individual hardener has been determined. Stratification occurs only with polyamide resin hardener, used as epoxy curing agent. Cross section of dried coating film is analyzed under optical microscope, then further characterized by FTIR, HATR, SEM-EDX, X-ray mapping. After stratification, two distinct coating layers are obtained with titanium dioxide pigmented chlorinated at the air interface and iron oxide pigmented epoxy resin towards substrate.

Tension superficielleIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Silicone polymers have the unique ability to lower the surface tension of organic oils and thereby present a different aesthetic effect in cosmetic formulations. Thi$ allows silicone polymers to be added at less than 10% concentration and often less than 5% concentration and provide a different customer experience than achieved by standard silicones. Since the formulation is 90%+ identical to the starting formulation, the time and work needed to evaluate change is minimised. Likewise, the toxicology of the formulation, the need for many raw materials and the cost change is minimised.
