CUCURBITACIN B.

Questionable CAS 6199-67-3 / SKIN CONDITIONING

Cucurbitacin B is a potent natural compound extensively researched for its anti-inflammatory and antioxidant properties, primarily in pharmaceutical contexts. While showing promise in mitigating skin inflammation in animal models, its safety profile for topical cosmetic applications remains largely unassessed.

anti-inflammatory antioxidant keratinocyte proliferation inhibitor

Science

This compound exerts its anti-inflammatory effects by modulating key cellular pathways, specifically down-regulating NF-κB and STAT3 signaling within human keratinocytes and inhibiting the activation of the NOD-like receptor thermal protein domain associated protein 3 (NLRP3) inflammasome. Additionally, it demonstrates antioxidant capabilities through free radical scavenging and restoration of superoxide dismutase activity, alongside an ability to inhibit keratinocyte proliferation.

Stability

Cucurbitacin B is heat sensitive and requires refrigeration (0-10°C) for optimal stability. Its generally limited water solubility often necessitates advanced delivery systems, such as nanosuspensions or nanogels, to improve bioavailability, particularly in pharmaceutical applications.


Safety

CIR Status
Not reviewed
Sensitization risk Unknown

Primarily studied for its potent pharmacological activities, Cucurbitacin B has documented reports of high toxicity and a narrow therapeutic window, especially in anti-cancer contexts. While approved as an oral adjuvant therapy in China for certain medical conditions, there is no specific safety assessment from CIR or SCCS for cosmetic use, nor an FDA status for topical cosmetic application.

Our Assessment

Questionable

While Cucurbitacin B exhibits promising anti-inflammatory and antioxidant properties in preclinical studies, its noted high toxicity, narrow therapeutic window, and complete lack of cosmetic-specific safety assessments render its use in skincare highly questionable for precision formulations.
