The breakthrough in ethyl silicone oil technology has been successfully implemented, and a new product with a low acid value has opened up new application space in cosmetics

1.Patent transfer has drawn attention to the realization of technological breakthroughs in cosmetic-grade materials
Recently, a patent for the preparation method and application of ethyl silicone oil was successfully listed for transfer, attracting widespread attention from the silicone and beauty industries. This patent was developed by a university research team. It specifically addresses the industry pain point that traditional ethyl silicone oil cannot enter the cosmetics field due to its high residual acid value, opening up a brand-new application scenario for such high-performance materials. Previously, ethyl silicone oil was highly regarded in the industry for its excellent stability and potential for skin feel. However, the problem of irritation caused by excessive acid value kept it from the beauty field for a long time. This technological breakthrough fills the relevant gap.

2. Innovative processes enhance product performance to achieve multi-dimensional upgrades
The preparation technology adopted in this patent demonstrates significant advantages: ethylcyclosiloxane is used as the raw material, combined with hexethyldisiloxane as the capping agent, and the polymerization reaction is completed under the action of a solid superacid catalyst. After filtration to remove impurities, vacuum reduction to low boiling point and other processes, the finished product is obtained. Compared with traditional processes, the ethyl silicone oil produced by the new technology not only has a significantly reduced acid value, but also features good transparency, high yield, and strong stability. At the same time, it achieves uniform molecular weight distribution and controllable viscosity, with batch repeatability reaching industry high standards. These performance upgrades make it fully meet the dual requirements of cosmetics for the safety and functionality of raw materials.


3. Beauty scene adaptation unlocks diverse application possibilities
In cosmetic applications, this type of ethyl silicone oil has demonstrated multiple potentials. Its low acid value characteristic can prevent irritation to the skin and mucous membranes, and it is compatible with various dosage forms such as essence, lotion and foundation. Excellent transparency ensures the appearance and texture of makeup products, while stable chemical properties can extend the shelf life of the products. Industry insiders point out that as consumers' demands for the safety and long-lasting performance of beauty products increase, ethyl silicone oil, which combines skin feel regulation and stable protection functions, is expected to become a new type of raw material to replace traditional oils and play a core role in products such as sun protection and isolation, moisturizing and repairing.


4. The pace of technology transformation is accelerating and the market outlook continues to improve
This patent transfer was completed at a relatively low listed price, highlighting the practical orientation of technology transformation and lowering the threshold for subsequent industrial application. Data shows that the global beauty industry's demand for functional silicon-based raw materials is growing at an average annual rate of over 8%, while domestic high-end related raw materials have long relied on imports. The mass production and application of this type of ethyl silicone oil can not only fill the domestic gap of cosmetic-grade materials, but also participate in international competition by relying on its cost advantage. It is expected to form large-scale application within the next 2 to 3 years.
