According to GlobalData’s company profile on Kobayashi Pharmaceutical, Nanoemulsion cosmetics was a key innovation area identified from patents. Kobayashi Pharmaceutical's grant share as of January 2024 was 29%. Grant share is based on the ratio of number of grants to total number of patents.
A recently granted patent (Publication Number: US11833123B2) discloses a pharmaceutical composition containing lidocaine and/or its salt, housed in a container with an inner wall made of linear low-density polyethylene. The polyethylene used in the container has a side chain with a carbon number of 4 or less, ensuring the stability of the lidocaine within the composition. Additionally, the density of the linear low-density polyethylene falls within the range of 0.932 to 0.940 g/cm3, further contributing to the efficacy of the pharmaceutical composition.
Furthermore, the patented pharmaceutical composition can exist in the form of a liquid or a gel, providing versatility in its application. The method outlined in the patent aims to prevent the reduction in weight of lidocaine and/or its salt within the composition by utilizing the specific container material and structure. By placing the pharmaceutical composition in a container with the specified linear low-density polyethylene inner wall, which has a side chain with a carbon number of 4 or less, the method ensures the stability and integrity of the lidocaine component. This innovative approach not only safeguards the potency of the pharmaceutical composition but also enhances its shelf-life and effectiveness for medical use.
