Silica is chemically stable inorganic synthetic powder which has no stimulation to skin, and therefore it has been generally used for a cosmetic ingredient. Synthetic silica particles for color cosmetic have various shape such as spherical, flaky, or needle-shaped, and among them, multi-porous or hollow spherical particles with average size of 3∼15µm are commonly used.

This kind of spherical silica particles provide effective fluidity to color cosmetic products due to their morphological characteristics, and when applied to skin, provide soft feeling and wide spreadability to skin due to large fluidability of spherical particle.

Although silica material has transparent property due to its similar refractive index to water, spherical silica is used for the manufacture of transparent-looking but hiding cosmetic because of diffused reflection on the surface of spherical silica. And also, spherical silica is used as a diffusion-helping agent for emulsion cosmetic because its size is very fine and its surface is hydrophilic

Silight(trade name) powder has spherical shape with narrow size distribution, The size of Silight powder can be controlled by the manufacturing recipe, and Silight is multi-porous and hollow according to its size 2nm.

In our company spherical products with mean particle size between 3 to 10µm have been marketed which scatter light on the surface of its particle, which are transparent, but give natural coverage on skin.

Silight Powder Series

Silight 3M

• Hollow type, high bulk density, small size, oil absorption is higher than Silight 6M
  
• Not become transparent but white color of material itself is maintained when wetted in oil.
  
• Adhesion power is highest due to its small size
  
• Light diffusing effect and hiding effect of skin pores
  
• Suitable for providing soft and silky feeling to products

Silight 6M

• Hollow type, high bulk density
  
• White color of material itself is maintained when wetted in oil.
  
• Better spreadibilty and lower adhesion power than Silight 3M
  
• Suitable for anti-caking agent
  

Silight 10M

• Hollow and multi-porous, very light due to its low bulk density
  
• Suitable for additive or perfume carrier due to its high oil absorption
  
• Best spreadability, provides very soft feeling to skin
  
• Transparent feeing and light-eliminating effect when wetted in oil due to its shallow surface
  thickness and porous structure
  
• Suitable for the payoff control of pressed-type product
