Question 1

What does Aluminum Powder/Ci 77000 do in a cosmetic formula?

Accepted Answer

This ingredient functions as an insoluble colorant and effect pigment, adding silver, metallic reflectance, opacity, and visual dimension to makeup, nail products, and specialty personal care formulas.

Question 2

Is Aluminum Powder/Ci 77000 clean?

Accepted Answer

From a clean-beauty perspective, it is not a common skin sensitizer, but some standards scrutinize fine metal powders because inhalation exposure, particle size, and purity matter. It is generally more straightforward in pressed, bound, or anhydrous formats than in loose powders or sprays.

Question 3

Is Aluminum Powder/Ci 77000 sustainable?

Accepted Answer

This material comes from mined ore and energy-intensive refining rather than renewable feedstocks. It is inorganic and not biodegradable, with the main sustainability questions tied to extraction, processing energy, and end-of-life persistence as particulate matter.

Question 4

Is Aluminum Powder/Ci 77000 COSMOS-approved?

Accepted Answer

It can be permitted in COSMOS-natural and COSMOS-organic products as a non-organic mineral colorant when it meets purity and processing criteria, but it does not contribute organic content. Its Green Chemistry fit is mixed because it is nonrenewable and persistent, though it is insoluble, used at low levels, and does not require complex solvent chemistry in the finished formula.

Question 5

How does Aluminum Powder/Ci 77000 work chemically?

Accepted Answer

This material is an elemental, insoluble particulate that creates reflectance by scattering and reflecting visible light, with visual performance driven by particle size, shape, surface treatment, and dispersion quality. It is typically used at low pigment levels for shimmer or opacity, is most stable in anhydrous or near-neutral systems, and can be less compatible with strongly acidic or alkaline conditions if uncoated.
