A natural dye produced by a fungus native to the Amazon can be used in cosmetics, according to research reported by Agência FAPESP, the news agency of the Brazilian research funding foundation FAPESP. For color-cosmetic formulators, the finding points to a potential new class of bio-derived pigments from one of the world's richest biodiversity reservoirs.

The development sits at the intersection of two commercial currents: rising demand for natural colorants in cosmetics and growing scientific investment in Amazonian bioprospecting. Brazil's research establishment has repeatedly turned to fungal and plant species from the biome as sources of novel functional ingredients, and this dye is the latest candidate to clear the threshold from laboratory observation to stated applicability in finished products.

Why does a fungal dye matter to formulators?

Natural pigments carry a specific set of formulation trade-offs. Botanical colorants such as beetroot or carmine alternatives often struggle with pH sensitivity, heat instability and batch-to-batch variation. A fungal-derived dye, produced potentially through fermentation rather than wild harvest, could offer a more controllable supply chain and consistent chromatic output than plant extraction — a longstanding procurement pain point in the natural colorant segment.

Fermentation-sourced ingredients also fit the manufacturing logic that cosmetic suppliers have built out over the past decade. Biotech platforms already supply squalane, hyaluronic acid and a range of actives via microbial production; pigments are a natural extension of that model.

What questions remain before commercial adoption?

The report establishes applicability in cosmetics, but the path from research finding to INCI listing and commercial supply involves several gating steps that buyers and regulatory teams will need to track:

• INCI designation: a new cosmetic colorant requires a name assignment and, for colorants in many jurisdictions, inclusion on approved positive lists — the EU's Annex IV among the strictest
• Safety dossiers: genotoxicity, irritancy and systemic toxicity data at use concentrations
• Stability performance: behavior across typical cosmetic pH ranges and under UV exposure
• Supply economics: whether the dye can be produced at scale through cultivation rather than extraction from wild fungal material

In the EU, synthetic and natural colorants alike face the positive-list regime under Regulation (EC) No 1223/2009, meaning a novel fungal pigment cannot simply be dropped into a formulation destined for European shelves. Any would-be supplier will need to fund the regulatory work before the ingredient becomes procurable at scale.

What does this signal for sourcing strategy?

For procurement teams, the item is an early-stage watch rather than an actionable brief. The relevant signal is directional: Brazilian institutions continue to convert Amazonian biodiversity into ingredient leads, and FAPESP-backed science has historically fed supplier pipelines in hair care, skin care and color cosmetics.

Formulators evaluating natural colorant alternatives — whether for clean-label positioning, vegan certification or carmine replacement — can add fungal pigments to the candidate set alongside mineral, botanical and fermentation-derived options already on the market.

The next data points to watch are concrete: publication of the underlying study with characterization of the pigment's chemical structure, any patent filings from the research team, and the emergence of a supplier or licensing partner prepared to carry the dye through INCI registration and regional colorant approvals. Until those steps land, the Amazonian fungus dye remains a research-stage lead with a clear commercial rationale behind it.
