1. In skin care products
        Fumed silica can be used in ointments, gels, and creams to increase the consistency, stability, and thixotropy of the products. It allows the product to apply more smoothly without feeling astringent. For W/O emulsion-type products, hydrophobic fumed silica can be used to increase the viscosity of the product, reduce greasiness, and improve the freshness of the product.

2. In sunscreen products
       Currently, physical sunscreen agents and chemical sunscreen agents are mainly used to achieve sun protection effects. Chemical sunscreens can be dissolved in the oil phase, resulting in products with a delicate texture and light skin feel. However, they will gradually decompose under the influence of ultraviolet rays, affecting the sunscreen effect. In order to ensure that the product has a high enough SPF value, the dosage of chemical sunscreens needs to be increased, but high doses of chemical sunscreens may increase irritation and easily cause skin allergies. The advantages of physical sunscreens are that they are inert and will not photodegrade, and there is no problem of skin absorption. However, their particles are easy to agglomerate and deposit, and the skin feel and hand feel are not good when used. Especially for products with high SPF values, they spread evenly on the skin. is a problem.

However, by adding a small amount of fumed silica to the formula, the problem of physical sunscreen agglomeration and deposition can be solved. Fumed silica can form a protective layer on the surface of physical sunscreen particles, fill in the uneven surface, reduce the attraction between particles, reduce the possibility of agglomeration, and make the system more uniform and stable. In addition, fumed silica also has thixotropic properties, which helps the product spread evenly on the skin, improves the skin feel and feel when applied, and comprehensively improves product performance.


In recent years, people's understanding of fumed silica has gradually increased, making it widely used in the field of personal care products, including skin care products, sunscreen products, makeup, antiperspirants, hair care products, shower gels, facial cleansers and other products. Fumed silica can solve the problem of suspending solid particles at low viscosity and imparts excellent thixotropy to the system. Therefore, it has become one of the necessary raw materials in high-end skin care products, liquid foundation, mascara, lip gloss and other products. With the deepening of research, the application of fumed silica in personal care products will be further expanded.
