Ingredient profile

Undaria pinnatifida extract is produced by water or hydro-alcoholic extraction of Undaria pinnatifida — typically the fronds harvested in late winter to early spring. The extract contains fucoidan-family polysaccharides, alginates, minerals, amino acids, and trace fucoxanthin.

The mekabu fraction (sporophyll, a separate anatomical part of the same seaweed) is sometimes marketed as a distinct cosmetic ingredient with its own specification.

OEM applications

In cosmetics, wakame extract appears in face masks, essences, body products, and hair care. Marine-positioning storytelling drives much of the use-case narrative.

In food, wakame is a staple vegetable in Japanese cuisine — miso soup, seaweed salad, sunomono, and various dried preparations.

  • CosIng database — INCI: Undaria Pinnatifida Extract
Q. Are there iodine or heavy-metal disclosure requirements similar to kombu?

Yes — like kombu, wakame is a brown seaweed that accumulates iodine and trace heavy metals, and cosmetic-grade COAs should include heavy-metal panel results. Buyers exporting to the EU should confirm compliance with Annex II/III of EU Cosmetics Regulation 1223/2009.

Q. Is Undaria pinnatifida considered an invasive species, and does this affect sourcing claims?

Undaria pinnatifida is listed as one of the world's worst invasive species in non-native marine environments, but Japanese-domestic harvests use cultivated and wild stocks within native habitat. Origin documentation should specify Japanese cultivation and natural-habitat sourcing.

  • IUCN Global Invasive Species Database — Undaria pinnatifida
Q. What is the typical extraction format and use level?

Liquid BG/water extracts at 1:1 to 1:10 plant-to-solvent ratios are most common, with cosmetic use levels typically 0.5–3%. Specialty fractions (fucoidan-enriched fractions, e.g.) are also marketed for premium positioning at lower doses.
