Plankton extract

Plankton extract (CAS 91079-57-1), also referenced commercially as marine plankton extract, is a bioactive marine-derived ingredient obtained from microalgae and zooplankton sources.

It delivers a concentrated profile of amino acids, peptides, vitamins, and trace minerals that support skin conditioning and nutritional fortification across multiple formulation types.

In skincare and cosmetic formulations, plankton extract functions as a humectant and antioxidant active, incorporated into serums, creams, and masks targeting hydration and environmental stress defense.

Hair care manufacturers use it in conditioning treatments where its amino acid content supports fiber integrity and moisture retention for high-performance personal care products.

Nutraceutical and functional food producers incorporate it as a source of marine-derived micronutrients in supplement capsules, protein blends, and fortified beverages for health-conscious consumers.

Pharmaceutical and health product formulators source it for use in topical preparations where marine bioactives are positioned as skin-supportive actives in specialized medical applications.

Plankton extract is typically supplied as a liquid aqueous solution or freeze-dried powder, with the powder form preferred for applications requiring extended shelf life or precise dosing.

Standard concentrations in liquid form vary by supplier, with both cosmetic-grade and food-grade specifications available depending on the target market and regional safety standards.
