In recent years there have been reports of allergenic symptoms initiated by protein from natural rubber. Therefore, a study on protein leaching from natural rubber glove using surfactant under pressure with adjusted pH has been investigated. Analysis of residual protein in rubber glove was carried out by mean of modified Lowry. The results indicate that the leaching solutions (KOH, NaOH, HCl, H2SO4, SDS, CTAB and TERIC(N10)) can reduce the protein to certain extent among which SDS yields a highest value of 98.7% from the initial protein value (1575 mug/g). Further study on using pressure in conjunction with agitation during leaching has shown that when pressure is 40 bar protein is reduced 1.6 times more than at atmospheric condition. The leaching of protein using SDS solution performed in a glove manufacturing factory, before and after curing, confirmed the reduction of protein at 1.7 times that of leaching by water alone. In the laboratory, protein leaching from natural rubber glove by this technique can achieve a reduction of protein from the average value of 1575 mug/g to 21 mug/g.
