Abstract

Natural rubber field latex is preserved and stabilised against coagulation by using a nonionic surfactant having a hydrophilic lipophilic balance (HLB) value of at least 12 either alone or in combination with small quantities of ammonia. The preferred nonionic surfactants have HLB values from 14 to 20, and include ethylene condensation products of lipophilic especially fatty alcohol residues. The use of this preservative system prevents coagulation whilst permitting bacterial action which can have beneficial effects especially when the latex is gelled by heat or mechanical action. The beneficial bacterial activity can be accelerated by seeding the latex with portions of mature bacteria rich lattices preserved according to the invention.
