Get to Know Ingredients in Mineral Makeup

Just thought I'd start a thread on ingredients. As a formulator,
I'm willing to answer all the questions I'm able to.
I'll start off with a few thought provoking points...
Did you know that the INCI ingredient name doesn't tell you
everything about that ingredient?
Did you know that ingredients are listed in the order of
predominance, from most to least?
Lets look at Silica. It's a great ingredient that provides slip,
silkiness, diffuses lines and imperfections, and can absorb
excess oil.
However there are sooooo many types and variations of silica.
Some maintain their spherical shape, others do not, as they
absorb moisture.
While what TYPE a company uses is probably proprietary, its
something to think about when you're looking at ING lists. Even
if it looks the same, it may not feel or perform the same.

Great info. ;)
I very recently got into diy and I was blown away by how all the
different micas and sericites can have the same incl (correct me
if I'm wrong). But just out of curiosity, I've noticed a lot of
eye shadows that have mica and carnauba wax. Since I can't see
an indie formulator mixing straight wax into a powder, am I
correct in saying that it's a surface treated mica? If so,
wouldnt the wax be an extremely small proportion of the formula?
I'm quite curious how much of treated mica's are the "treatment"
ingredients. It you don't want answer that's totally fine, I
just feel like a kid who graduated from Lego's to power tools x]

This is a great thread! I'm hoping to get answers as I look into
making my own shadows and pigments. My questions are mostly
regarding...what can I add to, say, micas such as TKB to make
them have more slip and adhesion in regards to a binding
ingredient, while retaining most of the mica's brilliant colors?
Same with stability so that the product lasts a long time?

Yes, carnuba is generally a surface treatment on the mica. There
are many other treated/coated micas. We use Magnesium myristate
and jojoba treated in our formulas. And yes it's a very small %
of the formula so would be at the end of the ingredient list
:)
