Bladderwrack extract

Bladderwrack extract (CAS 84696-13-9), derived from the brown seaweed Fucus vesiculosus, is a marine-sourced ingredient used across cosmetics, nutraceuticals, and functional food applications.

Rich in bioactive compounds including fucoidan and alginates, it functions as an antioxidant, humectant, and skin-conditioning agent in finished formulations for various industries.

In personal care, it is incorporated into anti-aging creams, serums, and body treatments where its moisture-retention properties support skin hydration claims for high-end cosmetic lines.

Nutraceutical manufacturers use it in capsule and tablet formats targeting thyroid support, weight management, and iodine supplementation for health-conscious consumers globally.

In functional food and beverage products, it serves as a natural source of minerals and antioxidants for health-positioned formulations requiring clean label ingredients.

Topical cosmetic formulators also include it in scalp care and hair treatment products to support conditioning performance and improve the overall texture of hair care products.

Bladderwrack extract is supplied as a liquid extract, dry powder, or standardized concentrate, with the 10% extract being a commonly traded specification in the chemical market.

Food-grade and cosmetic-grade designations are standard across the market. Standardization is typically based on fucoidan or iodine content depending on the intended application.
