Ingredient review
Black 2
INCI: CI 77268:1
A safe and widely used black pigment for coloring cosmetics, but may cause irritation in sensitive eyes or if inhaled as loose powder.
In plain English
CI 77268:1 is a black pigment, also known as Black 2 or carbon black, used to give a deep black color to makeup like eyeliner, mascara, and eyeshadow. It is a synthetic ingredient made by burning hydrocarbons to create fine black particles. In cosmetics, it is generally considered safe for external use, but care is needed to avoid inhaling the powder form, and some people with very sensitive eyes may experience mild irritation.

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 Black 2.
- 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 black pigment produced by the incomplete combustion of natural gas or petroleum, resulting in fine carbon particles. It is approved for use in cosmetics by regulators like the FDA and EU.
How it works
It works by absorbing visible light across the spectrum, giving a deep black color to the product. The fine particles adhere to skin or lashes, providing opaque coverage and intense color payoff.
Pros
Deep color payoff
Provides a true, intense black that is hard to achieve with natural pigments, making it ideal for dramatic eye looks.
Regulatory approval
Approved by the FDA and EU for use in cosmetics, with a long history of safe use when applied topically.
Cons and cautions
Potential eye irritation
If particles get into the eye, they can cause redness, tearing, or discomfort, especially for those with sensitive eyes or contact lenses.
Inhalation risk
Loose powder forms can be inhaled, which may irritate the lungs or cause more serious issues with chronic exposure, so avoid airborne dust.
Best for
- People who want bold, black eye makeup
- Those looking for a cost-effective black pigment in cosmetics
Use caution if
- Individuals with extremely sensitive eyes or a history of eye irritation
- Anyone who frequently inhales loose powders (e.g., makeup artists without proper ventilation)
Usage tips
Safety summary
Generally safe for topical cosmetic use when formulated properly. The main risks are eye irritation and inhalation of loose powder. Regulatory bodies have set purity standards to limit contaminants.
Research notes
Studies confirm low skin irritation and sensitization potential. Inhalation studies in occupational settings show risks for lung irritation, but cosmetic use is considered safe with proper formulation.
Common label clues
- Typical concentration
- Typically 0.1% to 10% depending on desired shade intensity
- Regulatory status
- Approved as a color additive for cosmetics in the US (FDA) and EU (EC), with restrictions on use in eye area products to ensure safety.
- Common uses

- Environmental note
- Carbon black is produced from fossil fuels, so its environmental footprint includes greenhouse gas emissions. Some manufacturers are exploring bio-based alternatives.
Good to know
- CI 77268:1 is distinct from CI 77266 (Black 2) but both are carbon-based black pigments.
- It is often listed as 'Black 2' on ingredient labels in the US and EU.
