The environmental-friendly low-ozone silicone oil technology is accelerating its iteration. The raw materials for cosmetics have entered a new stage of green compliance. 

1. Domestic and international regulations have tightened, and restrictions on cyclosiloxanes have been implemented.
In 2026, global regulations on organic silicon raw materials for cosmetics will be tightened simultaneously. In China, it has been clearly stipulated that D4 cyclosiloxane will be prohibited in cosmetics starting from 2027, and the residue limit of impurities will be strictly controlled at 0.1%. In the European Union, D4, D5, and D6 types of cyclic siloxanes will be restricted in a phased manner. Staying products and rinse-off products in the beauty care and makeup categories will implement the highest control standards. Previously, a large number of traditional silicone oil production processes were prone to generating ring by-products. Exporting beauty brands have repeatedly encountered product retention and removal due to the excessive ring body content in raw materials, forcing upstream raw material enterprises to upgrade their production lines. Industry research shows that over 70% of cosmetic formula manufacturers have changed their raw material suppliers in the past six months, prioritizing the selection of low-ring and non-ring silicone oil products. 

2. The deep evaporation process has been widely adopted, and high-purity linear silicone oil has achieved a breakthrough in mass production.
The core technologies of the industry have been upgraded in the ring removal and purification stage. The new multi-level vacuum deep evaporation process has been put into large-scale application, which can control the total impurity content of D4 and D5 in silicone oil within 50 ppm, far below the regulatory threshold. The new process also optimizes the control of polymerization reactions, narrows the molecular weight distribution range of silicone oil, and reduces the batch error of viscosity to ±5%. It solves the formulation problems such as storage stratification of traditional raw materials and unstable paste consistency. This process does not require additional chemical additives, and the production energy consumption has decreased by more than 20% simultaneously, balancing product purity and low-carbon production requirements. 

3. Biorenewable silicone oil research and development has been successfully implemented, meeting the demands of the pure cosmetics market
Based on molecular modification technology, several biorenewable modified cosmetic silicone oils have completed pilot production. By grafting natural plant lipid groups through silane, the silicone oil retains its smooth skin feel while enhancing its degradability, meeting the needs of the pure cosmetics and natural skincare sectors. The compatibility of the modified silicone oil has significantly improved, and it can be stably compounded with plant oils and active extracts, suitable for low-irritation products such as sensitive skin repair creams, children's hair care, and sunscreen lotions. No need to combine a large amount of emulsifiers, a thin and non-sticky film-forming system can be formed. 

4. The industry has established a compliance quality control system and standardized the traceability of raw materials.
With the full implementation of the cosmetics raw material safety reporting system, compliant silicone oil raw materials need to complete platform registration and provide a unique reporting code, along with complete GC-MS ring structure detection and toxicological safety assessment reports. The industry gradually unified the classification standards for cosmetic-grade silicone oil, distinguishing between industrial grade, cosmetics grade, and medical aesthetics-specific grade raw materials, and preventing low-priced industrial silicone oil from flowing into the cosmetics supply chain. Raw material enterprises also simultaneously opened third-party sample testing services to provide complete technical support for cosmetic brand formula adjustment and export compliance review.
