BRASSICA NIGRA SEED POWDER.

Optional CAS 90064-15-6 / SKIN CONDITIONING

A finely milled powder derived from black mustard seeds that functions as a dual-action skincare ingredient combining mechanical exfoliation with biochemical stimulation. Upon contact with water, this botanical powder activates enzymatic pathways that release circulation-boosting compounds while physically buffing away dead skin cells. The ingredient delivers antioxidant protection through naturally occurring glucosinolates and polyphenols.

Summary

Exfoliant Skin Conditioning Agent Circulation Stimulant

Science

Mechanism of Action

Functions through a two-pronged approach: mechanical abrasion from particle structure removes surface debris, while enzymatic conversion of sinigrin to allyl isothiocyanate (AITC) stimulates localized blood circulation and provides anti-inflammatory benefits via glucosinolate pathways.

Stability

Powder disperses in both aqueous and oil phases but remains insoluble; requires slightly acidic environment to preserve glucosinolate integrity; prone to darkening in water-based formulations over time

Synergies

  • Gentle surfactants for scrub bases
  • Antioxidant actives
  • Circulation-boosting compounds

Conflicts

  • Strong oxidizing agents
  • High-temperature processing
  • Highly alkaline formulations

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk High

EU-listed as skin conditioning agent; exercise caution in leave-on products due to potential AITC-induced irritation and flushing
