BARIUM SULFATE
For Paint, Ink, and Plastics
■Overview
Barium sulfate is an extremely chemically stable compound with high heat, chemical, and water resistance. It is used as a general extender pigment due to its high true specific gravity and refractive index equivalent to plastic.
Especially, barium sulfate with extremely fine particles has characteristics to contribute to improving dispersivity and chromogenic of colored pigments, the orientation of bright pigments, and smoother coating.
In addition, we also offer grades that are suitable for hygienic products and medical use that are compliant with standards for quasi-drugs raw materials.

Long-Lasting Soft Focus Effect of H-LFM Lamellar Barium Sulfate
Lamellar Barium sulfate has a higher soft-focus effect than mica and has proven effective for long-lasting makeup applications.
《Evaluation Method》
First, after face washing, apply skin lotion and milky lotion and allow them to soak in for 15 minutes. Next, apply an appropriate quantity of powder foundation, and quantify the number of spots and pores using a VISIA skin analyzer.
Comparative data of flake-shaped barium sulfate and other materials
The soft effect of flake-shaped barium sulfate is higher than with other materials.
《Measurement conditions》
0.2g of sample + 0.8g of silicone(PWC = 20 wt%) were dispersed twice with 25 turns at 100 pounds in a Hoover muller,applied to a glass plate with a 1mil applicator,and measured in a haze meter.
