| Message: | Use for face ,body,directly touch skin all need safe.our cosmetic grade pigments tested by QC AND QA.each batch provide for SDS TDS. high grade series which is very popular.we highly focus on safe. Compare common series,a key feature of the cosmetic grade pigments is between the share of the incoming light which is reflected by the pigment and the share of light completely passing through. The color of the transmitted light is complementary to the color of the reflected light. For example, a red reflection color goes with a green transmission color, while yellow and blue form another pair of reflected and transmitted light. url:http://www.zhuyan-pigment.com |
