The cosmetics database considers polymethylsilsesquioxane as a 100% safe ingredient. Polydimethylsiloxane is generally used in skin care products to moisturize the skin, but also can play a lubricating and moisturizing effect, generally will not cause irritation to the skin, and will not cause harm to the skin.
Polymethlsilsesquioxane is also called Spherical Silicone Resin Powder, Microspheric Silicone Resin Powder, Silicone Resin Powder, PMSQ Powder, Spherical Powder. which can be used for cosmetic and personal care
Figure 2-2 (a murb) shows the scattering effect of parallel light passing through silicone particles with diameters of 2 μ m and 3 μ m,
For the light diffusion films embossed on different surfaces, the haze increases to different degrees. The haze of the diffusion film of the cylindrical lens array increases rapidly, while that of the microlens array increases slowly.
The diffusion effect of cylindrical lens diffusion films doped with different concentrations of organosilicon particles.
Light transmittance and haze are two important indexes to characterize the properties of light diffusion films. The former determines the intensity of light passing through, while the latter determines the uniformity and diffusion effect of line and surface light sources
