Abstract: A latex formulation for making an elastomeric product, more particularly an elastomeric glove. The formulation comprises a mixture of at least one base polymer, a cross-linker; and a pH adjuster, where the pH adjuster provides a pH range of 9.5 to 10.5 to the latex composition. Still further, the present invention discloses a method for preparing a latex formulation for making elastomeric products, such as an elastomeric glove, without using accelerators, zinc oxide or sulphur.

Still further, the present invention discloses a method for preparing a latex formulation for making elastomeric product, more particularly an elastomeric glove without using accelerators, zinc oxide and sulphur, which comprises the steps of mixing a base polymer with a pH adjuster, stirring the mixture for time period ranging from 20 minutes to 30 minutes, adding a cross-linker to the mixture, stirring said mixture for an hour, optionally adding at least one or more additive to said mixture, adding water to said mixture to achieve a total solid content (TSC) ranging in between 13% to 30% by w/w, allowing said mixture to mature.
