Specific heat of mixtures of bentonitic clay with sea water or distilled water for their use in thermotherapy

Assessment of three Spanish clays for their use in pelotherapy

“…Specific heat was determined using a BT 2.15 SETARAM calorimeter. Simultaneous control of the thermodynamic variables, flow and temperature was achieved using a SETARAM controller and Setsoft2000 software (Casás et al, 2011). Measurements of thermal conductivity were taken using the Decagon KD2 Pro Thermal Properties Analyzer (Decagon Devices Inc., Pullman, WA, EE.UU.).…”

“…Some properties related to suitability for pelotherapy have been studied in clays from Italy (Cara et al, 2000a(Cara et al, , 2000bFerrand and Yvon, 1991;Summa and Tateo, 1998), Portugal (Gomes and Silva, 2001;Rebelo et al, 2010Rebelo et al, , 2011, Cape Verde (Gomes et al, 2008) and Spain (Casás et al, 2011(Casás et al, , 2013Legido et al, 2007;Ortiz de Zarate et al, 2010). Furthermore, some properties of peloids prepared with clays, different types of water and different maturation conditions have been studied Curini et al, 1990;Fernández-González et al, 2013;Gámiz et al, 2009;Quintela et al, 2010;Sánchez et al, 2002;Tateo et al, 2010;Veniale et al, 2004).…”

Study of traditional Tunisian medina clays used in therapeutic and cosmetic mud-packs

“…For comparative purposes, known amount of pastes (50% mass/volume) were conditioned at 60°C in a cylindrical polyethylene terephthalate cell and then immersed in a thermostatic bath at 25°C, measuring the temperature sample in the interval 50°C to 25°C, by means of a thermometric probe located in the center of the cell. The temperature interval was selected to evaluate the performance of the studied pastes in hot mud-pack therapy of painful arthritic processes and other chronic pain related diseases (Caridad et al, 2014;Casas et al, 2011Casas et al, , 2013Espejo-Antúnez et al, 2013). Experimental cooling data were fitted by using the Newton Law describing thermal exchange between two bodies in contact at different temperatures.…”

The Potential Use of Marine Microalgae and Cyanobacteria in Cosmetics and Thalassotherapy

“…To prepare the marine mud, commercial bentonite was used (supplied by Bentonitas Especiales S.A. and previously discussed in Casás et al 2011, andCasás et al 2013 [56,57]) and mixed with seawater. This mixture was compared with another of similar characteristics, but with triple-distilled water as the liquid substrate.…”
