This product is a water repellent silica gel, prepared using innovative surface treatment technology.
This product can be blended readily in W/O emulsion cream formulations.
The surface treated particle maintains the porous silica gel structure underneath the hydrophobic layer.Thus this product retains a moisture absorption function which is a feature of silica gel. (as the diagram below indicates )
Note) when strongly stirred and waved by hand, powder is absorbed and precipitated.
II . Texture improvement
[Test method]
:
Apply 0.5mg/cm test powder on artificial leather Supplare
(made by Idemitsu Techno Fine ) , and evaluated texture by KES-SE friction tester (made by Kato tech and sensor:artificial leather Supplare,load 25g) .
III . Dispersibility to oils
[Test method]
:
Add Dimethicone 6cs in test powder gradually, and mix by palette knife.
The point that triangular pyramid is made is oil absorption point, add Dimethicone 6cs, and the point that it fluids when it was scooped by palette knife. The difference of both points is indicator of dispersibility.
IV . Hygroscopicity
[Test method]
:
Spread about 0.3g test sample in petri dish thinly, and stand under relative humidity from 10 to 90 % for 48 hours at 25. After 48 hours, measure its
gravity and evaluate hygroscopicity of test sample.
