CAULERPA TAXIFOLIA EXTRACT.

Valuable CAS 223749-77-7 / SKIN PROTECTING

A nutrient-dense marine botanical derived from green algae, frequently referred to as 'green caviar' for its rich concentration of protective polysaccharides and secondary metabolites. This extract serves as a multifunctional bioactive that bridges the gap between deep cellular hydration and advanced antioxidant defense.

Summary

Antioxidant Humectant Skin Protecting Anti-inflammatory Collagen Booster

Science

Mechanism of Action

Caulerpa Taxifolia operates through a four-tier approach: its high polysaccharide content (reaching 73%) creates a hygroscopic film that binds moisture to the stratum corneum; caulerpenyne and phenolic compounds neutralize reactive oxygen species (ROS) to prevent oxidative stress; it modulates the inflammatory response by downregulating pro-inflammatory cytokines like IL-1β and IL-6; and it maintains structural integrity by boosting Type I procollagen while inhibiting matrix metalloproteinases (collagenase).

Key findings

  1. 01 Demonstrated 18.33% free radical scavenging capacity at a 0.1% concentration of isolated polysaccharides.
  2. 02 Achieved significant antioxidant efficacy with an EC50 of 0.38% in ABTS assays, confirming potent performance at low inclusion levels.
  3. 03 Identified IC50 of 45.44 μg/mL for cellular growth inhibition, suggesting potential protective bioactivity against abnormal cellular proliferation.

Due to its 'Green Caviar' marketing appeal, this ingredient is often used at trace amounts (below 0.1%) for label claims. While it shows some antioxidant activity at 0.1%, significant collagen support and moisture retention typically require concentrations closer to 0.5%–1%.

Stability

Polysaccharides are stable in aqueous environments but sensitive to temperatures exceeding 80°C. Terpenoid fractions are lipophilic and require stable emulsification to prevent phase separation.

Synergies

  • Hyaluronic Acid
  • Vitamin E
  • Marine Collagen
  • Peptides

Conflicts

  • High electrolyte concentrations
  • Strong oxidizing agents
  • Extreme pH levels below 4.0 or above 8.0
