Thank you, Nan!

Hydrogenated Polysobutene is an emollient and palmetic acid is a

fatty acid ... given the lung/ey irritant value of mica, I would

state that both are added in an attempt to weigh down the mica

particles and lessen the possibility of inhalent/occular irritation.

Hydrogenated Polyisobutene and Palmitic Acid are used in Engelhard's

line of Cellini colors.

Cellini Blue (INCI name: Mica, Titanium Dioxide, Blue 1 Lake,

Hydrogenated Polyisobutene and Palmitic Acid)

Cellini Coral (INCI name: Mica, Titanium Dioxide, Red 40 Lake,

Hydrogenated Polyisobutene and Palmitic Acid)

Cellini Green (INCI name: Mica, Titanium Dioxide, Blue 1 Lake, Yellow

5 Lake, Hydrogenated Polyisobutene and Palmitic Acid)

Cellini Red (INCI name: Mica, Titanium Dioxide, Red 7 Lake,

Hydrogenated Polyisobutene and Palmitic Acid)

Cellini Yellow (INCI name: Mica, Titanium Dioxide, Yellow 5 Lake,

Hydrogenated Polyisobutene and Palmitic Acid)

It appears that Hydrogenated Polyisobutene and Palmitic Acid are used

to predisperse the pigments and to make them hydrophobic.

Quoting from the Engelhard's website:

http://www.engelhard.com/

" Cellini colors are clean, intense, FDA-approved organic colors with

pearlescent effects. They provide a luminescent look that adds

brightness and depth to a broad range of cosmetics, especially lip,

face and eye products. For example, in eye shadows, Cellini colors

yield more intense shades than previously available. The Cellini Blue

grade also is the first absorption blue pearl that can be used in lip

area products in the United States. This pigment family also can be

used to enhance many personal care products.

Engelhard Cellini colors are especially easy to work with because the

colorant is predispersed, and they contain a wetting agent that makes

them hydrophobic. These features can reduce or even avoid costly and

time-intensive steps such as creating hydrophobic surfaces, grinding,

deagglomerating and dispersing stand-alone organic colorants. The

wetting agent in Cellini colors also tends to reduce colorant bleed in

aqueous systems. This agent also can improve performance in wet/dry

applications and makes Cellini colors especially effective in powders,

lipsticks and other anhydrous applications.

Four of the five Cellini grades (Blue, Yellow, Green and Coral) are

designated for broad application in the U.S., including eye-area

applications. Cellini Red was created for eye-area use in Japan. In the

U.S., the Red grade is allowed for all products other than eye-area

cosmetics. "

I wasn't aware of that. Can you provide any literature citations, urls etc that

show that safety of cosmetic mica is a " hugh issue in the industry " ?
