The latest technology in the use of silicon powder and silicon suspension in cosmetics

Silicon has a special touch in organic materials and is one of the indispensable raw materials for improving the touch performance of cosmetics. At present, half of the new products in the US market contain silicon materials. In particular, about 90% of new products in hair conditioning products contain silicon. The types of cosmetic materials that can be used in the Japanese Pharmaceutical Law are dimethylsilicon and A. A silicon-denatured organic substance such as a silicon-based silicon, a cyclic silicon, a polyester-modified silicon, an alkoxy-modified silicon, an amino-denatured organic-modified silicon, an enoate copolymer, or a methylsilanol condensate. These raw materials are mainly liquid materials, and silicon powders and silicon suspensions are significantly different from the above-mentioned raw materials in that they are elastic solid materials and have characteristics not found in the above raw materials. Therefore, it is expected to become a raw material for the production of new products in cosmetics.

Silicone powder
    Silicone has the advantages of safety, durability and insulation, and is widely used in many fields such as food and medical. The high molecular weight polydimethylsiloxane (gum) is bridged by a vinyl to obtain elasticity, and the silica gel is made into a spherical elastic powder by a single forming technique, wherein the three-lobed E-505C and the three-lobed E ─ 506C is a silica gel powder used in cosmetics, with an average particle size of about 3UM spherical powder. The three-lobed E-505 is a three-lobed-506 product containing dimethicone. The basic skeleton and appearance of the rubber are the same, but the physical properties of the oil-containing oil are different. The E-506C is higher in comparison with the oil absorption, but it depends on whether the oil is included beforehand. If the oil absorption of the spherical nylon powder is about 0.5, it can be said that the three-lobed shape has excellent medium oil absorption. In this way, it can be confirmed that the oily skin can be prevented by absorbing excess skin fat when mixed with the skin cosmetic material.

The following is an example of a formulation for preventing oiliness.

Ring silicon 80.0
Three-petal E-506C 15.0
Dimethyl silicon (20cs) 5.0

  Silicone, like gelatin, has a different feel than silicon used in the past. Including silicon surface properties and a touch, it can produce a sliding and dry feeling of solid rolling on the skin, as well as deformation, rolling moist feeling and stretching, which have never been seen before. Can be used on powder substrates.

Silicon powder suspension
    The silicon powder suspension is a product in which silicon powder is dispersed in water. By dispersing in water in advance, it can be easily mixed with a water-based cosmetic, and it is also easy to carry out primary particle dispersion in powders and oily cosmetics, and it is possible to maintain the characteristics of silica powder which is dry and light-slip.
