According to GlobalData’s company profile on Top Glove, Nanoemulsion cosmetics was a key innovation area identified from patents. Top Glove's grant share as of September 2023 was 45%. Grant share is based on the ratio of number of grants to total number of patents.

A recently granted patent (Publication Number: US11725097B2) describes a unique formulation for elastomeric materials, specifically gloves. The formulation consists of several components, including base polymers, crosslinkers, stabilizers, activators, antioxidants, pigments, waxes, antifoams, and pH adjusters.

The base polymer component of the formulation is a mixture of two types of rubber: polyisoprene rubber (Base polymer A) and polychloroprene rubber (Base polymer B). The ratio of these polymers ranges between 30 parts per hundred rubber (phr) to 50 phr for Base polymer A and 50 phr to 70 phr for Base polymer B.

The crosslinker component includes two types: Crosslinker A and Crosslinker B. Crosslinker A is used in an amount ranging between 0.40 phr to 1.00 phr, while Crosslinker B is used in an amount ranging between 0.10 phr to 0.40 phr, both based on the total dry weight of the base polymers.

Stabilizers are also included in the formulation, with Stabilizer A used with Base polymer A and Stabilizer B used with Base polymer B. Stabilizer A is used in an amount ranging between 0.15 phr to 1.00 phr, and Stabilizer B is used in an amount ranging between 0.50 phr to 2.50 phr, both based on the total dry weight of the base polymers.

Other components of the formulation include an activator (0.40 phr to 1.00 phr), an antioxidant (0.50 phr to 2.00 phr), a pigment (0.80 phr to 1.50 phr), a wax (0.30 phr to 0.80 phr), an antifoam (0.01 phr to 0.15 phr), and a pH adjuster (0.8 phr to 1.5 phr).

Importantly, this formulation is an accelerator-free elastomeric formulation, meaning it does not include an accelerator that accelerates the crosslinking process.

The patent also mentions that the formulation can be used to produce gloves that are accelerator-free and elastomeric.

Overall, this patent describes a specific formulation for elastomeric materials, particularly gloves, that includes a combination of base polymers, crosslinkers, stabilizers, activators, antioxidants, pigments, waxes, antifoams, and pH adjusters. The formulation is unique in that it does not require an accelerator for the crosslinking process. This innovation could potentially lead to the development of gloves that are more comfortable and safer for users.
