(2017-05-08)
Article
Restricted access - publisher's policyGiven the carcinogenic character of formaldehyde, it should be reliably determined in any substrate . The EN ISO 17226 Standard is the Official Method to quantify formaldehyde in leather. However, sorne misunderstandings ... -
Environmental assessment of dehydration processes for bovine leather
(2017-02-15)
Article
Restricted access - publisher's policyThe purpose of this work is to compare the environmental impact of two systems for processing bovine leather: (i) a new continuous system that consists in dehydration and tanning and post-tanning by immersion versus (ii) ... -
Reduction of the formaldehyde content in leathers treated with formaldehyde resins by means of plant polyphenols
(2017-02-03)
Article
Open AccessFormaldehyde has applications in many industrial processes, including synthesis of resins and syntans to be used in the retanning process of leather. When resins are employed, they can hydrolyse, releasing formaldehyde. ... -
Low carbon products to design innovative leather processes. Part III: optimization of an eco-friendly formulation using tara
(2015-09-01)
Article
Restricted access - publisher's policyThe aim of this work was to design a new pretanning formulation by using the fruit of the Tara tree (Caesalpinia Spinosa) as the sole source of vegetable tannin. The innovative aspect of this work embodies a new-tailored ... -
Determination of formaldehyde content in leather: Standard EN ISO 17226, revision and possible improvements
(2016-07)
Article
Restricted access - publisher's policyThe retanning process is the main application of formaldehyde in the tanning industry since formaldehyde participates in two groups of synthetic organic tanning agents: syntans and resins. Resins can be hydrolysed with the ...
