Beta-Ionone

TL;DR. This ingredient is used primarily as a fragrance component, adding a floral, woody, berry-like note at very low levels. It can also help round out fragrance accords in lotions, shampoos, deodorants, and fine fragrance.

What does Beta-Ionone do in a cosmetic formula?

This ingredient is used primarily as a fragrance component, adding a floral, woody, berry-like note at very low levels. It can also help round out fragrance accords in lotions, shampoos, deodorants, and fine fragrance.

Is Beta-Ionone clean?

From a clean-beauty perspective, this ingredient sits in the fragrance category, so the main issues are disclosure, sensitization potential, and compliance with IFRA limits. It is not broadly viewed as a high-concern material, but it can appear on restricted or reportable fragrance-allergen lists depending on market and concentration.

Is Beta-Ionone sustainable?

This material may be produced synthetically from petrochemical or terpene-derived feedstocks, and it can also occur in nature at trace levels. It is expected to biodegrade, but its fragrance chemistry and aquatic classification can create some environmental scrutiny at higher release levels.

Is Beta-Ionone COSMOS-approved?

It is only aligned with COSMOS when supplied as a compliant natural fragrance component or natural isolate under the standard’s fragrance rules. Synthetic grades do not fit COSMOS-organic or COSMOS-natural positioning, and its Green Chemistry profile depends heavily on feedstock origin and manufacturing route.

How does Beta-Ionone work chemically?

The molecule is an unsaturated cyclic ketone with moderate hydrophobicity and high odor impact, which is why it is typically used in fragrance concentrates at trace to low-percentage levels rather than as a bulk formula ingredient. It is generally stable in many anhydrous and emulsion systems, but like many unsaturated aroma compounds it can be sensitive to oxidation, so antioxidants, airtight packaging, and compatibility testing are common formulation considerations.
