Cosmetic-grade antioxidant actives for a German skincare brand

Problema do cliente

A German skincare brand wanted to add a plant-antioxidant serum and needed actives that fit both their EU documentation workflow and their manufacturing process. The blocker was not the molecules but the practicalities: poorly water-soluble actives, an existing emulsification process, and a documentation pack their regulatory partner could file.

Requisito técnico

Cosmetic-grade actives that fit both the brand's EU documentation workflow and an existing emulsification process — a micronized particle-size grade matched to their serum manufacturing and a solubility-handling approach suited to a water-based, poorly-soluble system.

Solução da GreeneryBio

During a paid pilot we supplied trans-resveratrol (from Polygonum cuspidatum) and quercetin with batch COAs plus allergen, heavy-metal and identity documentation suited to EU cosmetic filing support. We worked with their formulators on a micronized grade and a solubility-handling approach appropriate for their water-based system rather than shipping a default powder.

Notas de formulação

Both actives are practically insoluble in water, so the conversation centered on particle size, pre-dispersion and where in the process they are added — exactly the formulation detail a default sales sheet skips.

Documentos fornecidos

• Batch-specific COA
• Allergen documentation for EU cosmetic filing support
• Heavy-metal and identity documentation

Resultado

The pilot confirmed a grade and handling method that fit the brand's serum process, and the documentation pack matched what their regulatory partner needed. The engagement remains at the pilot stage by the customer's choice as they finalize the formula; a bulk specification has been drafted for when they move to scale.

• Supplied cosmetic-grade antioxidant actives with batch COA plus allergen and heavy-metal documentation for EU filing support
• Matched a micronized particle-size grade to the brand's serum manufacturing process
• Confirmed a solubility-handling approach for a water-based formulation during the pilot
