In plain English

CI 75135 is a man-made red pigment that gives lipsticks, blushes, and eyeshadows their bright red or pink color. It's a 'lake' pigment, meaning it's made by combining a dye with a metal salt to make it insoluble in water, so it stays put on your skin without bleeding or fading quickly. Think of it like a tiny colored particle that sits on the surface of your skin or lips, providing long-lasting color.

Quick decision guide

Useful, but context matters

CI 75135 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.

  1. Step 1Start with the score, then check the irritation and clogging risk before judging CI 75135.
  2. Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
  3. 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

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

moderate

There is useful support, but formula details and claim strength still matter.

What it is

CI 75135 is a synthetic organic pigment classified as a D&C Red No. 30 Lake. It is produced by precipitating a red dye (typically a xanthene dye) onto an aluminum or other metal hydroxide substrate, creating a stable, insoluble powder that imparts color to cosmetic products.

How it works

In a cosmetic product, CI 75135 works by physically coating the skin or hair with tiny colored particles. Because it is insoluble in water and oils, it resists smudging and fading, providing consistent color throughout wear. It is typically dispersed in the product's base (like a lipstick wax or powder) and adheres to the application surface.

Pros

Vibrant, long-lasting color

CI 75135 delivers intense red or pink shades that resist fading and bleeding, making it ideal for lipsticks and blushes that need to stay put through eating and drinking.

Low irritation potential

Compared to some other red pigments, CI 75135 has a low irritation risk and is generally well-tolerated by most skin types, including sensitive skin.

Cons and cautions

Potential allergen for some

A small percentage of people may experience allergic contact dermatitis or irritation from synthetic lake pigments, especially if used repeatedly on the lips or around the eyes.

Not natural or biodegradable

As a synthetic pigment, CI 75135 is not derived from natural sources and may not be biodegradable, which can be a concern for environmentally conscious consumers.

Best for

  • Anyone looking for a bold red or pink color in lipsticks or blushes
  • People with normal to oily skin who want long-lasting color

Use caution if

  • Individuals with known allergies to synthetic colorants or lakes
  • Those seeking completely natural or plant-based cosmetics

Usage tips

Always patch test a new product containing CI 75135 on a small area of skin before full application, especially if you have sensitive skin.
Remove makeup thoroughly at the end of the day to prevent any potential buildup of pigment particles on the skin.

Safety summary

CI 75135 is considered safe for use in cosmetics at typical concentrations, with a low risk of irritation and sensitization for most people. However, individuals with known allergies to synthetic colorants should avoid it. Regulatory bodies like the FDA and EU CosIng have approved it for cosmetic use.

Research notes

Research on CI 75135 primarily focuses on its safety as a cosmetic colorant. Studies indicate low acute toxicity and minimal skin irritation. It is not considered a carcinogen or reproductive toxin. Allergic reactions are rare but documented.

Common label clues

Typical concentration
Typically 0.1% to 5% depending on desired color intensity
Regulatory status
Approved for use in cosmetics in the US (FDA) and EU (as a listed colorant). Some restrictions apply for eye-area use in certain regions.
Common uses
Lipsticks, Blushes, Eyeshadows, Nail polishes
Environmental note
CI 75135 is a synthetic pigment that does not readily biodegrade. Its production involves chemical synthesis and metal salts, which may have environmental impacts if not properly managed.

Good to know

  • CI 75135 is also known as D&C Red No. 30 Lake in the US and is approved for use in cosmetics by the FDA.
  • The 'Lake' designation means the pigment is insoluble, which helps it stay on the skin without migrating.
