: I'm not sure about the effects of diluting eo in an oil. I am still
: playing with the oils in my mix. I am thinking about doing emu oil on
: my next test. Not a cost friendly oil but the size of the molecule
: make it a good carrier for other thing so would it help transport the
: dye. Sounds like a question for superwoman(aka CCJ)

I don't have the wardrobe to be superwoman ......... I sure don't have
the figure any more. Ther are some other cartoon characters I might
resemble.

I don't think hennotannic acid needs anything to help "carry" it into
the skin. In fact, I'm fairly certain that's counter productive.
Hennotannic acid is about the size of an amino acid and it cruises
into a skin cell and binds to keratin all by itself, no assistance
needed. What is NEEDS is a solvent to get the hydrophobic dye out of
it's little chlorophyll package efficiently and make it available ...
then it walks right in all by itself.

Lemon juice is there to keep the acid an acid so it maintains it's
nice red, and lemon juice probably assists breaking down the
cellulostic material. The monoterpene alcohols, I believe, put more
of the hennotannic acid in to solution, so more is available to
supersaturate the skin cells.

Adding oil? Changes the drying properties and texture but mostly
hinders more than it helps, in my experience.

I'm going to be a very happy lady when I can find a prof to indulge me
in researching and nailing down this chemistry once and for all. This
is what I love so much about persuing henna through geography and
chemistry ... instead of squishy/mushy/feely investigations of magic
and ritual (which are fun but they don't serve to advance fundamental
understanding of henna) (because there's no way to quantify and test
things so other people can get some use out of it other than a warm
fuzzy feeling) (mind, that sort of fluff seems to sell paperbacks!)I
like to find ways to apply academic and scientific rigor to henna (and
when I nail something down, I do a "rigor dance"!)
