Laminaria Japonica Extract

Product Description

Our high-purity Laminaria Japonica Extract is standardized from Laminaria japonica kelp harvested from controlled marine sources, with direct factory supply and batch COA traceability for cosmetic formulators.

This INCI-listed extract delivers fucoidan, laminaran, and alginates that support polysaccharide hydration, oxidative stress modulation, and barrier-friendly mineral amino acid replenishment through marine bioactive pathways.

Unlike generic seaweed powders, our water–glycerin extract offers defined polysaccharide markers and consistent assay documentation—ideal for hydrating serums, essences, and barrier-support day creams at 1–5% w/w.

Key Benefits & Applications

Marine polysaccharide extract for hydrating, barrier-support, and oxidative defense applications across aqueous cosmetic systems.

• Fucoidan and laminaran modulate oxidative stress from UV and pollution exposure in day-care serums at 2–5% w/w.
• Polysaccharide-rich matrix binds atmospheric moisture for sustained deep hydration in essences and toners.
• Alginates form a breathable film that reduces transepidermal water loss in cream and lotion bases.
• Mineral amino acid profile supports ceramide-friendly barrier lipid balance after mild environmental stress.
• Marine sulfated polysaccharides calm visible redness in sensitive-skin toners and after-sun formulations.

Formulation Guidelines

Incorporate into cool-process aqueous phases below 40°C; compatible with humectants and barrier actives in serum-to-cream systems.

• Hydrating serum: 2–5% w/w in water phase; add post-emulsification when possible.
• Essence toner: 1–3% w/w; pair with glycerin or butylene glycol humectant bases.
• pH window: Stable 4.5–7.0; avoid prolonged exposure above pH 8.0.
• Processing: Add below 40°C; pre-dilute in hydrosol to reduce clumping risk.
• Compatibility: Avoid strong oxidizers; test with high-level acids before scale-up.
• Synergy: Combine with Hyaluronic Acid for layered polysaccharide humectant hydration and improved TEWL control.
