Abstract:
The Cosmetic Ingredient Review Expert Panel (Panel) assessed the safety of 20 sorbitan esters; this report included sorbitan esters that were reviewed in 1985 and 2002, as well as 3 previously unreviewed sorbitan esters (sorbitan undecylenate, sorbitan sesquicaprylate, and sorbitan palmate). Most of the sorbitan esters are reported to function in cosmetics as surfactant-emulsifying agents. The Panel reviewed the data from previous sorbitan ester reports, as well as additional data included in this report, to determine the safety of these ingredients. The Panel concluded that the sorbitan ester

Abstract:
This paper presents results of tribological research of a composition containing as a base, extract of waste blackberry seeds obtained by extraction under supercritical carbon dioxide conditions with sorbitan esters as additives (sorbitan trioleate (STO) sorbitan monolaurate (MLS) and etoxylated sorbitan monolaurate (EO20MLS)). The influence of the concentration of surfactants on the motion resistance, wear and anti-seize properties of the obtained lubricants was analysed. Two types of tests were performed: seizure, with linear load increase and constant load (four-ball device T02). The obtain

Abstract:
Lutein is a challenging compound to incorporate into food, as it is poorly soluble and unstable in aqueous solutions. In this study, the aim was to prepare stable encapsulates of lutein and lutein esters using feasible and straightforward techniques. Fine suspensions based on polyoxyethylene sorbitan monooleate and medium-chain triglyceride oil micelle-like units with 3.45% lutein esters or 1.9% lutein equivalents provided high encapsulation efficiencies of 79% and 83%, respectively. Lutein encapsulated in fine suspensions showed superior stability, as 86% was retained within the formulation o

Abstract:
The aim of the work carried out was to develop an analytical method for characterising sorbitan ester surfactants, which could be used to monitor their manufacture and establish structure activity relationships. HPLC was the first analytical technique used, however despite evaluating various stationary and mobile phases a repeatable method could not be found. High temperature GC with splitless injection was then tried. A range of single polyol esters of varying fatty acid chain lengths were prepared and analysed to establish the ester species that would elute from the column. Using optimised c

Abstract:
O éster de sorbitan etoxilado (ESE) é obtido por meio de duas reações consecutivas. Na primeira reação, ácidos graxos são esterificados com sorbitol, gerando os ésteres de sorbitan, podendo ser utilizados nesta reação diferentes tipos de ácidos graxos, de diversas origens, produzindo ésteres com diferentes características. Em seguida, estes ésteres são modificados pela adição de óxido de eteno, obtendo-se então os ésteres de sorbitan etoxilados. Esses ésteres constituem um grupo de tensoativos não-iônicos com ampla aplicação em cosméticos, detergentes, produtos farmacêuticos, formulações agroq

La protection de l'environnement requiert l'emploi de lubrifiants acceptables pour le milieu, c'est à dire à écotoxicologie nulle à faible et à biodégradabilité élevée. Cette spécification devient impérative dans les industries agro-alimentaires ou les lubrifiants peuvent contaminer l'environnement (forêt, champs) et les aliments (grains, produits transformes). Afin de répondre à ce cahier des charges, de nouvelles molécules de type peresters de sorbitol ont été synthétisées.
