The patent is titled "A Kind of Phenyl Silicone Oil and Its Preparation Method" with the application number CN202310000456.7. The acquisition of this patent marks new progress in the company's technological innovation in the cosmetics field.
According to the patent abstract, the synthesis process of this phenyl silicone oil has the advantages of low alkoxy content and strong storage stability.

In addition, the product has a higher refractive index under the same viscosity, which is superior to similar products.
It is worth noting that Wanhua Chemical has obtained 267 patent authorizations so far this year, a decrease of 34.56% compared with the same period last year. However, the company's investment in research and development has continued to grow, reaching 4.55 billion yuan in 2024, a year-on-year increase of 11.51%. This indicates that despite the decline in the number of new patents, Wanhua Chemical still attaches importance to technological research and development to enhance product competitiveness.
Overall, Wanhua Chemical has shown a good development momentum in terms of patent authorization, R&D investment and intellectual property accumulation, and is expected to continue to play an important role in the cosmetics and other related fields in the future.
