According to GlobalData’s company profile on Shiseido, Nanoemulsion cosmetics was a key innovation area identified from patents. Shiseido's grant share as of September 2023 was 27%. Grant share is based on the ratio of number of grants to total number of patents.

A recently filed patent (Publication Number: US20230301879A1) describes an oil-in-water emulsion composition with several key components. The composition includes a copolymer of (meth)acrylic acid/alkyl (meth)acrylate/(meth)acrylic acid-POE monoalkyl ether ester (Component A), batyl alcohol (Component B), and at least 10% by mass of a polar oil in relation to the total amount of the emulsion (Component C).

In addition to the above components, the composition may also contain a higher alcohol (Component D) as described in claim 2. Claim 3 states that an alkyl-modified carboxyvinyl polymer (Component E) can be included in the composition. Furthermore, claim 4 specifies that the polar oil mentioned in Component C can be an ultraviolet absorber.

The patent also provides a preferred mass ratio of batyl alcohol (Component B) to the higher alcohol (Component D) in claim 5, which should be between 1:1 and 1:3. This ratio ensures the desired properties of the emulsion composition.

Lastly, claim 6 mentions the inclusion of a nonionic surfactant with a hydrophilic-lipophilic balance (HLB) of 10 to 20. The content of this surfactant should not exceed 0.6% by mass of the total emulsion composition.

Overall, this patent describes an oil-in-water emulsion composition that combines various components to achieve specific properties. The inclusion of the copolymer, batyl alcohol, polar oil, and other optional components allows for the creation of a stable and effective emulsion. The patent provides specific ratios and limits for the components, ensuring the desired characteristics of the composition.
