CI 77713
INCI: CI 77713
A safe, natural mineral pigment that adds color or opacity but offers no skincare benefits.
In plain English
CI 77713 is a mineral pigment made from magnesium carbonate. It's used in makeup to give products color or make them less transparent. Think of it like adding a tiny bit of natural chalk to a foundation to make it more opaque. It doesn't treat skin or provide moisture—it's purely for appearance.

Quick decision guide
Useful, but context matters
CI 77713 is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging CI 77713.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A naturally occurring mineral (magnesium carbonate) ground into a fine powder and used as a colorant in cosmetics. It appears as a white or off-white powder.
How it works
When mixed into a cosmetic formula, CI 77713 scatters light and adds opacity, helping to create a solid color base or adjust the shade. It does not react chemically with skin—it simply sits on the surface.
Pros
Low irritation risk
CI 77713 is a natural mineral that rarely causes allergic reactions or irritation, making it suitable for sensitive skin.
Clean opacity
It provides a smooth, opaque finish in powders and foundations without the heavy feel of some synthetic pigments.
Cons and cautions
No skincare value
This ingredient is purely for color and opacity—it won't hydrate, soothe, or protect your skin.
Potential dryness in powders
In high concentrations, it can absorb moisture from the skin, which may feel drying for those with already dry complexions.
Best for
- Anyone looking for a safe, natural colorant in makeup
- People with sensitive skin who want low-irritation pigments
Use caution if
- Those seeking skincare benefits from their color cosmetics
- Individuals with very dry skin who prefer hydrating formulas
Usage tips
Safety summary

Research notes
Studies on magnesium carbonate (CI 77713) show it is non-toxic and non-irritating in cosmetic use. It is not absorbed through the skin and poses minimal risk. However, research is limited compared to more common pigments.
Common label clues
- Typical concentration
- Typically 0.1–5% in color cosmetics
- Regulatory status
- Approved as a colorant in cosmetics by the FDA (21 CFR 73.2325) and listed in the EU CosIng database. No restrictions for general use.
- Common uses
- Pressed powders, Eyeshadows, Lip products, Nail polish
- Environmental note
- Mining of magnesium carbonate can have environmental impacts, but the ingredient itself is biodegradable and not persistent in the environment.
Good to know
- CI 77713 is also known as magnesite and is mined from natural deposits.
- It is often used in combination with other pigments to create custom shades.
