Immobilization of the proteins in the natural rubber with dialdehyde sodium alginate

Review on Prevalence, Risk Factors, and Research Advancements on the Use of Medical Gloves Concerning Hand Dermatitis Among Health Care Workers

“…Over the past decade, we identified seven research papers that depicted various advancements in overcoming HD through different strategies. In 2013, researchers [ 45 ] suggested the use of biodegradable dialdehyde sodium alginate to immobilize proteins on latex gloves. This is because proteins are distributed more uniformly in latex glove films with biodegradable dialdehyde sodium alginate, thereby effectively decreasing the extractable protein content.…”

“… Arctigenin showed anti-type I and IV allergic effects in vitro and in vivo, with good stability under latex glove manufacturing conditions. [ 45 ] 3. Natural proteases- bromelain & papain Develop an economical method to reduce extractable protein in latex gloves.…”

“…Furthermore, these review findings also demonstrate that the use of nitrile, powder-free, and accelerator-free gloves helps in reducing glove-related HD, although it is not completely overcome. Research advancements include the use of biodegradable dialdehyde, sodium alginate [ 45 ], arctigenin [ 46 ], bromelain [ 48 ], papain, UV-LED prototype photoreactors, and deproteinization together with structure-modified nanosilica with silane A174 to reduce or immobilize extractable proteins from latex gloves, which overcomes latex allergy [ 49 ]. Research has also suggested replacing commonly used cornstarch with calcium carbonate in gloves to ensure the safety of users who are allergic to cornstarch [ 50 ].…”

Additives for processing natural rubber and their application in small rubber plantations

“…Una tendencia marcada en los estudios más recientes ha sido la búsqueda de los llamados aditivos "verdes", es decir, que producen poco o ningún impacto medioambiental negativo, que puedan sustituir algunos de los aditivos usados tradicionalmente que en su mayoría son de carácter tóxico. En un estudio realizado por Gong et al (2013) se utilizó alginato de dialdehído sódico biodegradable para la inmovilización de las proteínas extraíbles presentes en el látex, las cuales causan alergias, con el fin de eliminar la etapa de dilución anteriormente descrita. Los resultados mostraron que el uso de este aditivo redujo la cantidad de proteínas extraíbles por debajo de los límites máximos permitidos por las normas que regulan este parámetro, como lo es la norma ASTM D5712, sin alterar significativamente las propiedades mecánicas y además, mejorando la degradabilidad de láminas de látex coagulado.…”

Self-crosslinked chitosan/dialdehyde xanthan gum blended hypromellose hydrogel for the controlled delivery of ampicillin, minocycline and rifampicin

“…The J o u r n a l P r e -p r o o f obtained oxidized polymer can efficiently react with amine groups via Schiff base reaction to form imide bonds. This technique has been widely applied in the preparation of dialdehyde biopolymers such as dialdehyde starch, dialdehyde sodium alginate, dialdehyde carboxymethyl cellulose and dialdehyde xanthan gum, which have been used as ideal crosslinking moieties to reinforce thermal, light barrier and mechanical properties of other materials [20][21][22].…”
