Zinnia Elegans Flower Extract

Zinnia Elegans Flower Extract is a botanical extract derived from the flowers of common zinnia, used in cosmetics for its antioxidant properties, sourced from a plant native to Mexico rich in polyphenolic compounds.

What it is

Zinnia Elegans Flower Extract is obtained from the flowers of Zinnia elegans (Asteraceae), an ornamental plant native to Mexico. The flowers contain polyphenolic compounds including chlorogenic acids, flavonoid glycosides (kaempferol, apigenin, and quercetin glycosides), anthocyanins, steroids, and saponins. Research has demonstrated moderate antioxidant activity through lipoxygenase (15-LOX) inhibition and iron chelation, which may help protect skin from oxidative stress. The extract has also been studied for antimicrobial and anti-inflammatory properties in preclinical models. In cosmetics, it is used as a skin conditioning and antioxidant ingredient at low concentrations. Clinical data on efficacy and safety in humans remains limited.

Safety & warnings

Zinnia belongs to the Asteraceae (compositae) family; individuals with known allergies to plants in this family (e.g., chamomile, chrysanthemum, ragweed) may be at higher risk of cross-reactivity. One study noted that zinnia pollen from polluted environments elicited stronger allergic reactions in sensitive individuals. No comedogenicity or irritancy data specific to the flower extract in cosmetic formulations has been published. Safety data in humans is limited; most studies are preclinical.

Origin & sourcing

Zinnia elegans is a herbaceous annual native to Mexico, first botanically collected in 1789 in Guerrero, Mexico. The flower extract is typically obtained by solvent or aqueous extraction of the dried or fresh flower heads. The plant belongs to the Asteraceae (daisy) family and is widely cultivated as an ornamental worldwide.

History

Zinnia elegans was described by Austrian botanist Nikolaus Joseph von Jacquin in 1792. The plant has a history of use in Aztec culture, where it was cultivated and associated with solar symbolism. Indigenous peoples in Central America used flower and leaf preparations topically for skin irritations and wounds. The genus Zinnia was named after German botanist Johann Gottfried Zinn. The related ingredient Zinnia Elegans Callus Culture Extract is registered in the EU CosIng database for antioxidant, hair conditioning, and humectant functions.

Questions everyone asks

What bioactive compounds are found in Zinnia elegans flowers?

The flowers contain flavonoid glycosides (kaempferol, apigenin, quercetin), chlorogenic acids, anthocyanins (pelargonidin and cyanidin diglucosides in red varieties), steroids, saponins, and phenolic acids. These compounds contribute to the extract's antioxidant and antimicrobial properties.

Is Zinnia Elegans Flower Extract safe for people with flower allergies?

Individuals allergic to Asteraceae family plants such as ragweed, chrysanthemum, or chamomile should use products containing this extract with caution, as cross-reactivity is possible. Human safety studies are limited, so patch testing is advisable for sensitive skin.

What is the difference between Zinnia Elegans Flower Extract and Zinnia Elegans Callus Culture Extract?

Zinnia Elegans Flower Extract is derived from the plant's flowers, while Zinnia Elegans Callus Culture Extract comes from laboratory-cultured callus tissue. The callus extract is registered in the EU CosIng database with functions including antioxidant, hair conditioning, and humectant; the flower e

How is Zinnia Elegans Flower Extract used in sunscreens and skin care?

The extract is typically included as a secondary antioxidant or skin conditioning ingredient in formulations, not as a UV filter. It is used at low concentrations to complement other active ingredients and help protect skin from oxidative stress.
