What is "CI 77491" and what is its purpose?

What is "CI 77491" and what is its purpose?

Also known as ferric oxide, CI 77491 is a red pigment of mineral origin, presented in powder form. It can be combined with other iron oxides such as CI 77499 (black) and CI 77492 (yellow). The F.D.A. authorises the use of CI 77491, which is considered a safe ingredient. The question that arises is: what is its utility? Here is what you need to know about CI 77491.

What you need to know about CI 77491.

Used within the framework of the I.N.C.I. system, the C.I. denomination for "Colour Index", followed by 5 digits, allows for the clear identification of dyes or pigments used in skincare and makeup products. Long used as a pigment, CI 77491 imparts its red colour to products, a primary colour.

For safety reasons, it is advisable to favour synthetic versions of iron oxide, manufactured in laboratories, for use in cosmetic care, despite their presence in nature. Indeed, naturally produced varieties may contain impurities. Heavy metals can contaminate uncontrolled oxides (manganese or other organic materials).

The production of iron oxides occurs through processes known as:

  • Thermal decomposition;

  • Precipitation;

  • Calcination.

Permitted by European regulations, iron oxides are not toxic, do not irritate the skin, and are not allergenic.

What is its utility in cosmetics?

CI 77491 is an intense brick-red cosmetic pigment. Of mineral origin, it is used in the creation of makeup products (foundations, concealers, face powders, blushes, eyeshadows, lipsticks, etc...), as well as in cosmetic products (soaps, body lotions, skincare creams, etc...) at low percentages to provide colour and shade to both liquid and solid preparations.. It also allows for the development of a range of shades by combining it with other iron oxides. At Typology, you will find it notably in the composition of our tinted serum, in our tinted concealer and in the new tinted lip balm, all of which are available in 6 shades to cater to a wide spectrum of different skin tones.
