Valuable CAS 9062-07-1 / SKIN CONDITIONING

Eucheuma Spinosum Extract, derived from red algae, is a versatile skincare ingredient celebrated for its multi-functional benefits. It acts as a potent antioxidant, helps to condition the skin, and contributes moisturizing effects, while also demonstrating antibacterial properties.

Skin-conditioning Antioxidant Moisturizing Antibacterial Stabilizing agent Emulsifying agent Thickening agent Gelling agent

Science

Mechanism of Action

This extract functions as an antioxidant primarily due to secondary metabolites such as flavonoids, steroids, terpenoids, saponins, and tannins, which neutralize free radicals by donating hydrogen atoms and inhibiting auto-oxidation. Its moisturizing capability stems from polysaccharide compounds like carrageenan, which act as humectants to attract and retain moisture in the skin. Additionally, Eucheuma spinosum extracts exhibit antibacterial activity by interfering with bacterial cell wall integrity, specifically by forming hydrogen bonds with peptidoglycans and disrupting their crosslinking. It is also recognized as a general skin conditioning agent.

Dusting Analysis

Not commonly dusted

Eucheuma Spinosum Extract is primarily utilized for its functional properties such as a skin conditioning agent, antioxidant, and as a stabilizing, emulsifying, thickening, or gelling agent. Its inherent water solubility and role in formulation suggest it is integrated into cosmetic matrices rather than applied as a loose powder, making dusting highly improbable.

Stability

While a gel formulation containing Eucheuma spinosum extract exhibited stable organoleptic, spreadability, and adhesion properties over 21 days, its pH and viscosity showed instability during the same period. The extract itself is soluble in polar solvents, including water and methanol, with its carrageenan components specifically noted for water solubility.

Sensitization risk Low

There is currently no explicit review status from regulatory bodies such as CIR, SCCS, or FDA specifically for Eucheuma spinosum extract's cosmetic use. An in vitro toxicity test, conducted in the context of antitumor research, indicated an LC50 of 58.82 ppm against Artemia salina Leach shrimp larvae, suggesting potential toxicity in this specific experimental model.
