In the cosmetics industry, silicone oils are widely used due to their excellent properties. Based on structure and characteristics, cosmetic silicone oils can be broadly categorized into three types: linear silicones, volatile silicones, and functional modified silicones.

Linear silicones, such as dimethicone, offer good lubrication and soft sensory feel, making them common in creams, lotions, and conditioners. Volatile silicones, like cyclomethicones (D4, D5, D6), evaporate quickly and are used in refreshing formulations to deliver a lightweight, non-sticky feel. Functional modified silicones introduce hydrophilic groups, alkyl chains, amino groups, or polyether chains to achieve diverse effects, such as enhanced emulsification, improved softness, and better adhesion.

By combining different types of silicones, formulators can achieve an ideal balance of texture, appearance, and user experience. For example, using a blend of linear and volatile silicones in skincare emulsions can offer an initial refreshing feel while maintaining long-term moisturization and softness.

However, choosing the right silicone oil also requires consideration of the overall formulation system, including emulsification method, stability requirements, and resistance to heat and light. Additionally, with growing environmental awareness worldwide, low-volatility, organic-certified, and sustainable silicones are gaining attention.
