Copolymer based on lauryl methacrylate and poly(ethylene glycol) methyl ether methacrylate as amphiphilic macrosurfactant: Synthesis, characterization and their application as dispersing agent for carbon nanotubes
(Pergamon-Elsevier Science Ltd, 2017-02)
The use of amphiphilic macrosurfactants as emulsifying agents has shown to have higher efficiency than that of low molecular weight surfactants. Compared to traditional surfactants, polymeric surfactants have lower critical ...
Characterization of the emulsifying activity of biosurfactants produced by lactic acid bacteria isolated from the Argentinian Patagonia
(Taylor & Francis, 2020-11)
This study aimed to characterize the emulsifying activity of biosurfactants extracted from lactic acid bacteria (LAB) originals of the Argentinian Patagonia. Nine LABs were isolated from sheep cheese and fishes. All the ...
Hydroxypropylmethylcellulose at the oil-water interface. Part II. Submicron-emulsions as affected by pH
(Elsevier, 2011-07)
The emulsifying behavior of four different commercial types of hydroxypropylmethylcellulose (HPMC) was studied and correlated with the properties of the interfacial films. Emulsions resulted multimodal when made by a high ...
New insights into bacterial bile resistance mechanisms: the role of bile salt hydrolase and its impact on human health
(Elsevier Science, 2018-10)
Bile acids (BA), the major components of bile, are biological detergents that facilitate the emulsification and solubilization of dietary lipids and also display potent antimicrobial activity, the bacterial membranes being ...
Functional fermented whey foods: their role on human health
(CRC Press-Taylor & Francis Group, 2014)
Whey is a by-product of the cheese industry, which is being widely used as food ingredient in bakery, meat, and dairy products due to its emulsification capacity, high solubility, and gelling, whipping/foaming, viscosity ...
PLGA nano- and microparticles for the controlled release of florfenicol: Experimental and theoretical study
(John Wiley & Sons Inc, 2019-03)
In this study, PLGA particle systems were studied for the controlled release of florfenicol, a broad spectrum antibiotic used in veterinary treatments. The emulsion-solvent evaporation technique was used for particle ...
Characterisation of freeze-dried flaxseed oil microcapsules obtained by multilayer emulsions
(Elsevier Science Sa, 2017-09)
The aim of this study was to obtain and characterise freeze-dried flaxseed oil microcapsules containing variable maltodextrin concentrations and to evaluate the influence of microencapsulation processing steps on the ...
A microextraction procedure based on an ionic liquid as ion-pairing agent optimized using a design of experiments for chromium species separation and determination from water samples
(Royal Society of Chemistry, 2013-07-19)
A microextraction methodology based on a room temperature ionic liquid (IL) as an ion-pairing reagent for determination of trace Cr(III) and Cr(VI) species is proposed. First, an ion-pair was formed between Cr(VI) species ...
