In recent years, the domestic market for personal care silicone has continued to expand. By 2025, the industry's scale will exceed 10.7 billion yuan. As an indispensable functional raw material, silicone oil, with its four core advantages of lubrication protection, water repellency and retention, stability of the system, and mild skin compatibility, has fully penetrated all categories of formulations in skincare, hair care, and cosmetics.

The basic physical and chemical properties of silicone oil determine its multiple values: when applied to the skin, it can form a thin and breathable protective film, blocking external stimuli such as wind and temperature differences, alleviating problems like dryness, peeling, and cracking in winter, and the film layer does not clog the skin, balancing moisturizing and refreshing sensations; excellent water repellency is the core selling point of hair care products, and after adding silicone oil to shampoo and conditioner, it can fill in damaged hair scales, reduce hair friction, smooth out the frizz caused by烫 and dyeing， and at the same time lock in the internal moisture of the hair strands， avoiding dryness and split ends. In face creams， foundation liquids， and sunscreen products， silicone oil can optimize the fluidity of the paste， prevent oil and water from separating， and maintain the stability of the formula for a long time， solving the problems of powder caking in makeup and dryness and dehydration in sunscreen.

Industry data shows that the consumption of silicone oil in the cosmetics field accounts for 31.6% of the total domestic demand. Low-ring modified phenyl silicone oil and IOTA-556 high-end cosmetics silicone oil gradually replace traditional ordinary dimethyl silicone oil， adapting to the EU REACH environmental control standards. Consumers' demand for softening hair care and smooth skin care has increased， forcing raw material enterprises to optimize the purity of silicone oil and reduce volatile ring body residues. Industry technicians introduced that high-quality cosmetics-grade silicone oil is non-irritating and has strong biological inertness， different from industrial crude silicone oil. Compliant modified silicone oil does not have problems such as clogging pores and damaging the scalp， and is not subject to problems such as clogging pores and damaging the scalp. It is a key auxiliary agent for beauty brands to enhance product usage experience.

With the acceleration of domestic cosmetics brands' overseas expansion， the export orders of cosmetics silicone oil have steadily increased. Orders for special silicone oil raw materials with low odor and high spreadability have increased by 18% year-on-year. Silicone oil raw material enterprises are continuously developing new hydrophilic modified products to balance water repellency protection and easy rinsing requirements， further expanding the application boundaries of cosmetics.
