Question 1

What does Ultramarine Blue CI 77007 do in a cosmetic formula?

Accepted Answer

This ingredient is a it colorant used to tint makeup, soaps, bath products, and some skin-care formulas. It is chosen for strong color payoff, opacity, and good light stability.

Question 2

Is Ultramarine Blue CI 77007 clean?

Accepted Answer

This material is generally well tolerated because it is insoluble and largely inert on skin, but specifications matter because inorganic colorants are controlled for trace metal impurities. In the U.S., it is allowed for externally applied cosmetics, including the eye area, but not for lip products.

Question 3

Is Ultramarine Blue CI 77007 sustainable?

Accepted Answer

This compound is typically made through high-temperature processing of mineral-derived inputs rather than direct botanical sourcing. It is not biodegradable in the usual organic-molecule sense, but it is inorganic, insoluble, and not considered bioaccumulative.

Question 4

Is Ultramarine Blue CI 77007 COSMOS-approved?

Accepted Answer

It is generally compatible with COSMOS-natural and COSMOS-organic colorant rules when it meets purity and origin requirements for approved inorganic pigments. From a Green Chemistry lens, its strengths are stability and low skin reactivity, while its tradeoff is energy-intensive manufacture and nonrenewable mineral feedstocks.

Question 5

How does Ultramarine Blue CI 77007 work chemically?

Accepted Answer

The molecule is an inorganic aluminosilicate lattice colorant where sulfur-containing chromophores are held inside a stable crystalline framework. It is used at variable levels depending on shade and product type, is insoluble in water and oils, and can be sensitive to strong acids, which may dull or decompose the color.
