ASCIDIAN TUNIC EXTRACT.

Valuable

Ascidian Tunic Extract is a novel marine-derived ingredient, rich in bioactive compounds, poised to address multiple signs of skin aging and environmental stress. It exhibits potent antioxidant, anti-inflammatory, and broad-spectrum enzyme inhibitory properties, alongside potential UV protection and antibacterial benefits.

Science

Mechanism of Action

This extract targets key enzymatic pathways involved in skin degradation, specifically inhibiting collagenase, elastase, and hyaluronidase to maintain dermal integrity and hydration. Its antioxidant capacity stems from effective radical scavenging, while anti-inflammatory action is mediated by attenuating nitric oxide production. The ingredient's diverse bioactives, including polysaccharides and fatty acids, also contribute to its UV protective potential and antimicrobial effects.

Key findings

  1. 01 In a study utilizing a hot water extract from Styela clava tunic waste, anticollagenase activity (IC50) was observed at 0.5058%, demonstrating efficacy comparable to ascorbic acid.
  2. 02 An ethanol extract from Styela clava tunic waste exhibited antielastase activity (IC50) at 0.0356%, although this activity was noted to be significantly lower than ursolic acid.
  3. 03 An ethyl acetate extract from Styela clava tunic waste showed antihyaluronidase activity (IC50) at 0.0210%, with activity lower than ketoprofen.
  4. 04 A hot water extract from Styela clava tunic waste effectively scavenged ABTS radicals (IC50) at 0.0192%, displaying antioxidant activity comparable to ascorbic acid.
  5. 05 Studies on Styela clava tunic (concentration unspecified) indicated its capacity to protect skin from UV radiation and elicit anti-inflammatory effects.
  6. 06 Crude methanol extract (0.5 mg) from Polycarpa aurata demonstrated inhibition of pathogenic bacteria.
  7. 07 Methanol extracts (0.07-0.095% MIC range) from Ascidian phallusia arabica showed antibacterial activity against human clinical isolates.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Unknown

The Cosmetic Ingredient Review (CIR) Expert Panel has not assessed Ascidian Tunic Extract. While no specific GHS classifications or general toxicity data (oral, dermal, inhalation) have been identified, it is noteworthy that certain raw ascidian species may contain defensive toxins. This information pertains to the unprocessed organism and does not necessarily reflect the safety profile of a purified cosmetic ingredient extract. Comprehensive safety assessments specific to cosmetic use are currently lacking, leading to an unknown sensitization risk.
