What does Citral do in a cosmetic formula?
This ingredient is primarily used as a fragrance component, adding a sharp lemon-like note to citrus, floral, and herbal scent profiles. It can also help mask base odors in a formula.
Is Citral clean?
From a clean-beauty perspective, this ingredient is accepted in many formulas but flagged because it is a recognized fragrance allergen and skin sensitizer for some users. It is subject to allergen disclosure requirements in the EU when present above threshold levels.
Is Citral sustainable?
This material can be sourced from certain essential oils or made synthetically, so its sustainability profile depends on feedstock and supplier practices. It is generally expected to biodegrade, but fragrance crop sourcing and solvent use can vary by supply chain.
Is Citral COSMOS-approved?
It can align with COSMOS-natural or COSMOS-organic products when it comes from permitted natural fragrance sources and meets the standard’s fragrance criteria. From a Green Chemistry view, renewable sourcing and biodegradability are positives, while sensitization potential and variable production routes keep it from a stronger alignment.
How does Citral work chemically?
The molecule is an acyclic monoterpene aldehyde, which explains both its bright citrus odor and its reactivity in finished formulas. It is usually used at trace fragrance levels, must be declared in the EU above 0.001% in leave-on products and 0.01% in rinse-off products, and is prone to oxidation, so antioxidants and air-limiting packaging can improve stability.
