What it is

A synthetic aromatic compound derived from cyclamen aldehyde, used exclusively as a fragrance ingredient in cosmetics and personal care products.

How it works

It works by evaporating from the skin and interacting with olfactory receptors, creating a floral scent perception. It does not have any active skincare function.

Pros

Pleasant floral scent

Provides a delicate, cyclamen-like fragrance that many find appealing in lotions and perfumes.

Synthetic stability

As a synthetic ingredient, it offers consistent scent quality and longevity compared to some natural extracts.

Cons and cautions

Potential skin irritation

Can cause redness, itching, or contact dermatitis in people with fragrance sensitivities or eczema-prone skin.

No skincare benefit

Adds only fragrance; it does not moisturize, protect, or improve skin health in any way.

Best for

  • People without fragrance sensitivities who enjoy floral-scented products
  • Those looking for a long-lasting floral note in their routine

Use caution if

  • Individuals with known fragrance allergies or sensitive, reactive skin

Usage tips

Patch test any product containing this ingredient on a small area of skin before full use.
If you have sensitive skin, look for fragrance-free alternatives to avoid potential irritation.

Safety summary

Generally safe for most people at low concentrations, but it is a known potential allergen. Those with fragrance sensitivities should exercise caution.

Research notes

Research indicates that cyclamen aldehyde derivatives can cause allergic contact dermatitis in susceptible individuals. Regulatory bodies like IFRA monitor and restrict its use to minimize risk.

Common label clues

Typical concentration
Typically used at very low levels, often below 1%, as a fragrance component.
Regulatory status
Approved for use in cosmetics in the EU and US, but subject to IFRA standards and concentration limits to reduce allergy risk.
Common uses
Perfumes, Fragranced lotions, Body washes, Cosmetic creams
Environmental note
As a synthetic compound, its environmental persistence and bioaccumulation potential are not well-documented, but it is generally used in very small amounts.

Good to know

  • Cyclamen aldehyde diethyl acetal is often listed simply as 'fragrance' or 'parfum' on labels, so it may not appear by name.
  • The International Fragrance Association (IFRA) sets usage limits for this ingredient to minimize sensitization risks.
