In plain English

This is a man-made chemical used to give products a nice smell, often described as floral, herbal, or slightly woody. It doesn't moisturize, exfoliate, or treat skin—it's purely for fragrance. While generally considered safe at low levels, it can be irritating for those with sensitive skin or fragrance allergies.

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

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

A synthetic ketone compound used as a fragrance ingredient in cosmetics and personal care products. It is not derived from plants or natural sources.

How it works

It evaporates from the skin or hair, releasing scent molecules that are detected by the nose. It does not interact with skin cells or provide any functional benefit beyond fragrance.

Pros

Pleasant scent

Adds a clean, floral-herbal fragrance that many people find appealing in lotions, cleansers, and perfumes.

Low irritation for most

At typical low concentrations, it is well-tolerated by most skin types without causing redness or stinging.

Cons and cautions

No skin benefit

This ingredient does nothing for your skin—no hydration, anti-aging, or barrier support. It's purely for scent.

Potential allergen

Like many fragrance ingredients, it can cause contact dermatitis or allergic reactions in people with fragrance sensitivities.

Best for

  • People who enjoy scented products and have no history of fragrance sensitivity
  • Those using rinse-off products like body wash or shampoo

Use caution if

  • Individuals with known fragrance allergies or very sensitive skin
  • Anyone preferring fragrance-free skincare

Usage tips

If you have sensitive skin, patch test a scented product on your inner arm before using it on your face.
For fragrance-free routines, check the full ingredient list—this compound may be hidden under 'parfum' or 'fragrance'.

Safety summary

Generally recognized as safe at low concentrations used in cosmetics. However, it can cause skin irritation or allergic reactions in sensitive individuals. Regulatory bodies have set usage limits to minimize risk.

Research notes

Studies show that dimethylcyclohexyl methyl ketone has low acute toxicity and is not a significant skin sensitizer at typical use levels. However, like many fragrance ingredients, it can cause contact dermatitis in susceptible people.

Common label clues

Typical concentration
Typically less than 1% in leave-on products; higher in rinse-off products
Regulatory status
Approved for use in cosmetics in the EU, US, and many other countries, with concentration limits set by the International Fragrance Association (IFRA).
Common uses
Perfumes, Fragranced lotions, Cleansers, Hair products
Environmental note
As a synthetic compound, it may not biodegrade quickly and could accumulate in waterways. Natural alternatives may have a lower environmental footprint.

Good to know

  • This ingredient is often listed simply as 'fragrance' or 'parfum' on labels, so you may not see its full name.
  • Regulatory bodies like the IFRA set safe usage limits for this compound in cosmetics.
