In today's world women are looking for natural and organic cosmetics for many reasons-to help the environment and to be good to their bodies are first and foremost.  In addition, some Jewish women look for kosher beauty products when adhering to religious rule that excludes wearing make-up during certain observances. This rule relates to dyeing or smoothing which is not allowed.  There is a caveat according to chabad.org:

There are some specially-produced powder-only makeups that are approved for Shabbat use by some halachic authorities. Since they are completely dry and do not attach to the skin, they do not fall into the forbidden category of dyeing. And when they are applied correctly -- with a completely dry brush, to completely dry skin -- they do not fall into the category of smoothing. It is also necessary to avoid mixing two color powders, even merely by using the same brush for both or by applying them to the same part of the skin. In order to be considered permissible on Shabbat, the makeup must be used exactly according to directions.
