In plain English

Score terms in plain English

Irritation risk

low

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

moderate

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

What it is

Acid Red 195 is a synthetic azo dye, chemically related to Erythrosine (FD&C Red No. 3). It is a water-soluble red powder that is used to color a wide range of cosmetic products.

How it works

In a cosmetic product, Acid Red 195 simply absorbs and reflects light in the red spectrum, imparting a visible color to the formulation. It does not interact with the skin or provide any functional benefit beyond aesthetics.

Pros

Vibrant color payoff

Provides a bright, consistent red or pink shade that stays stable in many cosmetic formulations like lipsticks and blushes.

Low cost and widely available

As a common synthetic dye, it is inexpensive and easy for manufacturers to source, keeping product prices lower.

Cons and cautions

No skincare benefit

This ingredient is purely cosmetic—it adds color but does not hydrate, protect, or improve skin health in any way.

Potential allergen

Some people, especially those with sensitive skin or a history of reactions to synthetic dyes, may experience redness, itching, or irritation.

Best for

  • Anyone looking for a red/pink color in their makeup
  • People without known dye allergies

Use caution if

  • Individuals with known allergies to azo dyes or sensitive skin prone to irritation

Usage tips

Check the full ingredient list if you have known sensitivities to synthetic dyes.
Patch test a new product containing this dye on a small area of skin before full use.

Safety summary

Acid Red 195 is considered safe for use in cosmetics at low concentrations by major regulatory bodies. However, it can cause allergic reactions in sensitive individuals, and there are ongoing discussions about the safety of certain azo dyes in general.

Research notes

Research on Acid Red 195 specifically is limited. Studies on related azo dyes suggest low acute toxicity but potential for skin sensitization in some people. No strong evidence links it to serious health risks at cosmetic use levels.

Common label clues

Typical concentration
Typically used at very low concentrations (0.1% or less) to achieve desired color.
Regulatory status
Approved for use in cosmetics in the EU, US, and many other countries, subject to concentration limits and purity requirements. In the US, it is regulated by the FDA as a color additive.
Common uses
Lipsticks, Blushes, Nail polishes, Soaps, Bath products
Environmental note
Synthetic azo dyes can be persistent in the environment if not properly treated during manufacturing. Some brands are moving toward natural alternatives for sustainability.

Good to know

  • Acid Red 195 is often listed under its CI number (CI 45430) on labels.
  • It is not the same as Red 40 or other common food dyes, but it is chemically similar.
