Q: What does Citral <18907 do in a cosmetic formula?

This ingredient is primarily used as a fragrance component, giving citrus and lemon-like notes to perfumes, skin care, hair care, and rinse-off products. It can also contribute minor deodorizing character within a fragrance blend.

Q: Is Citral <18907 clean?

From a clean beauty perspective, it is acceptable with caveats because it is an EU-listed fragrance allergen and must be declared on labels above set thresholds. Its main issue is skin sensitization potential, especially in leave-on products and in oxidized fragrance mixtures.

Q: Is Citral <18907 sustainable?

This material can be sourced from plant essential oils or made synthetically, so its sustainability profile depends on feedstock and supplier transparency. It is generally biodegradable and volatile, but concentrated fragrance materials still require careful aquatic release management in manufacturing.

Q: Is Citral <18907 COSMOS-approved?

It can fit COSMOS formulas when it comes from an approved natural aromatic source and is used within fragrance-allergen disclosure requirements, while synthetic versions are not aligned with COSMOS-natural or COSMOS-organic fragrance rules. Its Green Chemistry profile is stronger when plant-derived and readily biodegradable, but weaker because it is allergenic and oxidation-sensitive.

Q: How does Citral <18907 work chemically?

The molecule is an unsaturated monoterpene aldehyde made up of two geometric isomers, which explains both its bright citrus odor profile and its reactivity. It is typically used at low fragrance-blend levels, must be labeled in the EU above 0.001% in leave-on products and 0.01% in rinse-off products, and is best protected from air, light, and amine-containing systems because oxidation and aldehyde reactions can change performance.
