CARUM CARVI FRUIT OIL.

Valuable CAS 85940-31-4 / 8000-42-8 / FRAGRANCE, PERFUMING

An aromatic botanical extract derived from caraway seeds, recognized for its dual-action role as a potent antimicrobial and skin-soothing agent. In precision skincare, it is utilized to maintain microbiome balance and provide antioxidant protection while imparting a natural masking scent.

Summary

Antimicrobial Anti-inflammatory Antioxidant Masking Soothing

Science

Mechanism of Action

It functions by disrupting the amino acid metabolism of pathogenic bacteria and physically inhibiting the development of bacterial biofilms. It exerts anti-inflammatory effects by blocking 5-lipoxygenase and cyclooxygenase (COX) enzymes, which minimizes the production of pro-inflammatory leukotrienes and prostaglandins. Furthermore, it acts as an antioxidant by neutralizing free radicals and can influence skin pigmentation by upregulating the transcription factor MITF.
