The medical-grade methyl silicone oil in the personal care and medical fields has undergone an iterative upgrade. This marks a material innovation in the cleaning and beauty sectors. 

1.The new regulations force a shift towards upgraded raw materials, with low-allergenic and high-purity silicone oil becoming the mainstream.
The regulatory standards for cosmetics and pharmaceutical excipients in China have been continuously tightened. Traditional methyl silicone oil is subject to usage restrictions due to volatile substances and residual cyclic siloxanes. The new medical-grade methyl silicone oil in the cosmetics and healthcare industry adopts a deep refining process, with a volatile content lower than 0.3%, and contains no irritating impurities. It has passed the pharmacopoeia biocompatibility test and is suitable for applications such as skin care essences, hair care products, medical lubrication, and ointment carriers, perfectly meeting the current safety needs for clean beauty and medical consumables. 

2. The skin-feel optimization formula has been widely adopted, and high-end domestic products have increased their purchasing efforts.
The volatile methyl silicone oil, due to its light and easy-to-pour texture, no greasy feeling, and ability to brighten the skin, has become a core additive in cosmetics and skincare. The new modified silicone oil balances the spreading property and moisturizing ability, avoiding the shortcomings of traditional silicone oil being thick and causing a greasy feeling. Domestic beauty brands gradually increase the proportion of high-purity silicone oil used, replacing imported raw materials from overseas. In the 2026 cosmetics sub-market, the purchasing scale of cosmetic-specific methyl silicone oil has steadily increased, with a growth rate higher than that of traditional industrial categories. 

3. Expansion in the medical field, opening up new growth space
High-purity methyl silicone oil has strong biological inertness and no cytotoxicity. In recent years, it has rapidly penetrated into the fields of wound care, medical device lubrication, and drug sustained-release carriers. The medical scene has strict requirements for the purity of raw materials and batch consistency. Domestic production lines are equipped with sterile purification workshops to achieve fully dust-free production throughout the process. Relevant products have passed multiple medical material certifications and are gradually filling the domestic gap in the supply of high-end medical silicone-based materials. The annual compound growth rate of the segmented market is close to 20%. 

4. Sustainable modification research and development, overcoming the challenge of degradation and environmental protection
In response to the industry's pain point of insufficient degradation of traditional silicone oil, the industry has developed biogenic modified methyl silicone oil. Using renewable raw materials in the polymerization reaction, the carbon footprint of the product has been reduced by nearly 40%, and the wastewater degradation performance has been significantly improved, meeting the sustainable development requirements of domestic and international beauty brands. The related modification technology has completed pilot production and will gradually replace traditional petroleum-based methyl silicone oil, helping the cosmetics industry achieve green transformation and avoiding export risks caused by overseas chemical control barriers.
