SurfactantsIndex. décimale : 535.6 Couleur Résumé : The need to meet a raft of European legislation has fuelled a surge in demand for aqueous flexo printed paper and packaging materials which comply, writes by the author.
With consumers becoming increasingly environmentally aware and legislation becoming ever more stringent, the envirobment is slowly creeping up the business agenda. Europe is leading the way and setting a benchmark for the rest of the world, having serious implications for the majority of companies within the region. The inks market is no exception to this with regulations on health, safety and the environment becoming increasingly strict. This is with particular reference to legislation restricting Volative Organic Content (VOC) emissions to the atmosphere and the restriction of heavy metals content of coloured or printed packaging (CONEG regulations and European Directive 94/62/EC 1994). The need for ink markers to use colourants that meet these purity requirements has fuelled a surge in demand for aqueous flexo printed paper and packaging materials which comply. Artizan AF is a range of a high strength, ultramarine dispersions that have been developed specifically to cope with the high demands of the printing industry and are aimed directly at the aqueous flexographic ink market. The range consists of two products, Artizan AF-S, surfactant based allowing freedom of formulation and wide compatibility, and Artizan AF-R, acrylic resin based making it easy to incorporate and excellent to transfer. Table 1 shows the main differences between the two dispersions.Note de contenu : - Vibrant colours

Volumétrie (chimie analytique)Index. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : The direct two-phase titration method with use of solvatochromic dye, i.e. 5-(3-bromo-4-hydroxy-5-methoxyphenyl)-7,7-dimethyl-7H-indolo[1,2-a]quinolinium perchlorate (1) for cationic surfactants determination is presented which is the modification of an earlier described procedure for anionic surface active substances detection. The method was tested on standard solution of benzethonium chloride (cationic detergent) which enables to estimate its accuracy as well as on few commercially available products to verify its utility. The influence of pH value of the probe on the titration endpoint determination was discussed and a simple solution of this problem has been proposed.

Langues : Anglais (eng) Catégories : Coton Le coton est une fibre végétale qui entoure les graines des cotonniers "véritables"(Gossypium sp.), un arbuste de la famille des Malvacées. Cette fibre est généralement transformée en fil qui est tissé pour fabriquer des tissus. Le coton est la plus importante des fibres naturelles produites dans le monde. Depuis le XIXe siècle, il constitue, grâce aux progrès de l'industrialisation et de l'agronomie, la première fibre textile du monde (près de la moitié de la consommation mondiale de fibres textiles).

UltrasonsIndex. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : In recent years, the textile industry must go towards developing of new technologies to reduce the energy and water consumption. The use of ultrasound in textile wet processing is one way for this purpose. The aim of this work was to investigate the effects of ultrasonic energy on processing of cotton with nonionic softener. For this purpose, cotton fabric was treated with a nonionic fatty acid amide derivative softener in an ultrasonic bath. The physical properties of the fabrics treated with softener were compared with that treated in a conventional bath. As the results show, the treatment of fabrics with softeners in an ultrasound bath is more effective compared to a conventional method and it enhances the physical properties of cotton.

SurfactantsIndex. décimale : 667.9 Revêtements et enduits Résumé : The trend to rationalise paint production has led to a widespread use of a "universal colorant". A tinting system for a wide range of shades will be able to respond to the majority of user's requirements, reducing at the same time expensive and unwanted stock.
Nowadays, universal colorants are offered that meet the high quality standards of modern surface coatings. In order to obtain optimal results, it is necessary that the universal colorants are totally compatible with aqueous as well as with non aqueous paint system and remain stable upon storage. But even the best of these colorants may require some modification of paint base in order to obtain the satisfactory tinting. Otherwise, they would show problems of colour developments. When the tint bases are properly formulated, these colorants can be used for inplant shading, in retail outlets and in small batch operations that use dispensing colorant machines, thereby producing paints with a great variety of shades for the end user, with minimal inventory cost.Note de contenu : - Background

[article]
Titre : Use of inline near-infrared spectroscopy to predict the viscosity of shampoo using multivariate analysis Type de document : texte imprimé Auteurs : Kiran Haroon, Auteur ; A. Arafeh, Auteur ; P. Martin, Auteur ; T. Rodgers, Auteur ; C. Mendoza, Auteur ; M. Baker, Auteur Année de publication : 2019 Article en page(s) : p. 346-356 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Analyse de variance En statistique, l'analyse de la variance (terme souvent abrégé par le terme anglais ANOVA : ANalysis Of VAriance) est un ensemble de modèles statistiques utilisés pour vérifier si les moyennes des groupes proviennent d'une même population. Les groupes correspondent aux modalités d'une variable qualitative (p. ex. variable : traitement; modalités : programme d'entrainement sportif, suppléments alimentaires ; placebo) et les moyennes sont calculés à partir d'une variable continue (p. ex. gain musculaire).
Ce test s'applique lorsque l'on mesure une ou plusieurs variables explicatives catégorielles (appelées alors facteurs de variabilité, leurs différentes modalités étant parfois appelées "niveaux") qui ont de l'influence sur la loi d'une variable continue à expliquer. On parle d'analyse à un facteur lorsque l'analyse porte sur un modèle décrit par un seul facteur de variabilité, d'analyse à deux facteurs ou d'analyse multifactorielle sinon. (Wikipedia)

SurfactantsIndex. décimale : 668.5 Parfums et cosmétiques Résumé : - Objective : In the personal care industry, viscosity is a critical quality attribute that influences product quality and process economics. Like many industrial liquids, personal care liquids are complex non-Newtonian liquids made up of aqueous surfactant systems whose viscosity depends on the build-up of micellar networks. Measuring the viscosity of complex liquids offline is easily done using benchtop rheometers and viscometers. The challenge lies in measuring the viscosity of personal care liquids online during manufacturing. Being able to track the viscosity of such products through their manufacturing cycle will not only allow for better process control but also more enhanced quality control. Therefore, the aim of this work was to investigate how proxy measurements using inline near-infrared (NIR) spectroscopy in transmission mode can be used to predict the viscosity of shampoo. NIR spectroscopy has not, to the best our knowledge, been used to predict the viscosity of complex surfactant systems like shampoo and could significantly affect the way quality is monitored in a manufacturing environment.
- Method : This work focuses on viscosity changes because of differences in chloride content as salt is often used to adjust viscosity. The relationship between salt content and the viscosity of shampoo is well known following the salt curve. From an industrial perspective the region of interest for the formulation studied in this work only covers a small section of this curve. Therefore, two predictive models were developed: one covering the full range of the salt curve and another focusing on the industrially applicable region.
- Result : Models were produced using partial least squares (PLS) where both datasets showed some predictive ability with the concentrated region of interest showing enhanced performance [root mean square error of prediction (RMSEP) – 2.32 Pa s] compared with the larger range (RMSEP – 4.44 Pa s).
- Conclusion : This work provides a good starting point for developing robust predictive models for in situ viscosity measurements for shampoo manufacturing, where further work into different sources of variation and the extent of the modelling capability with regards to different formulations should be studied.Note de contenu : - MATERIALS AND METHODS : Samples - NIR data collection - Multivariate analysis - Reference method
