✓Contact areas with the skin are smaller by Raspberry shaped, and to expand

texture than spherical particle.

✓Even if in alumina particle with high refractive index being contained, be

wetted by silicone Oils, not Soft focus effect damage.

✓Formability improvement effects of a foundation.

✓Cost effectively than others silicone powder.

NH-RAS06

• Coefficient of dynamic friction (powdered bulk)

Measure of coefficient of mean friction(MIU) by friction

tester “KES-SE” (load 25 g, sensor: artificial leather) at

0.5mg/cm2 applied on artificial leather (IDEATEX JAPAN)

• Coefficient of dynamic friction (10% mixture with Talc)

Dispersed the sample to 10% in talc, and applied

0.5mg/cm2 in artificial leather (IDEATEX JAPAN). Measure

of coefficient of mean friction(MIU) by friction tester “KES-

• Photodiffusion effect

Dispersed samples into 0.1% in oil solutions that prepared

refractive index, using triethylhexanoin and

phenyltrimethicone,and haze value is measured by

spectrophotometer (HITACHI U-3900 spectrophotometer) .

7

Photodiffusion effectMeasurement condition: sample 30% to oil solutions that refractive rate was

coordinated, coating film of 20 μm was measured.

NH-RAS06 shows high haze value at similar refractive index (1.5) with skin.

→ Excellent soft focus.
