Because spherical silica powderis used for suspension and redispersibility in the liquid phase; it can have thickening and thixotropy properties in liquid; it can improve fluidity and storage stability in powder products such as powder cakes, thereby preventing The effect of agglomeration. Because of its high specific surface area, it can also act as an adsorbent and carrier, and can adsorb gases, liquids, and solid substances. used in lipsticks, pressed powders, foundation creams and other formulas, it has the following characteristics: good hydrophobicity, which can enhance the durability of makeup; good affinity to the skin; good dispersibility and compatibility in the oil phase.
application of spherical silicon dioxide:
For cosmetics, it is required to have a strong ability to shield ultraviolet rays. it is best to protect the human body from the harm of ultraviolet medium wave (UVB) and ultraviolet long wave (UVA). Essentially, ultraviolet shielding includes two aspects, one is the absorption of ultraviolet rays described above, and the other is the reflection of ultraviolet rays.
in the past, organic compounds were used as uv absorbers in sunscreen products. However, after increasing the addition amount to protect the skin from ultraviolet rays as much as possible, the nano-level high-purity spherical silica powder is an inorganic component, which is easily compatible with other components of cosmetics. it is non-toxic and odorless. it does not have the above problems. it is white in itself and can be easily colored. What is especially valuable is its strong ability to reflect ultraviolet light and good stability. it does not decompose, discolor, and does not interact The other components in the formula react chemically. These outstanding features have laid a good foundation for the upgrade of sunscreen cosmetics.
