Science
Mechanism of Action
It functions by disrupting the signaling pathways responsible for cellular overgrowth and inflammation, specifically reducing the nuclear translocation of NF-κB and pSTAT3. In research models, this leads to a significant reduction in the secretion of pro-inflammatory cytokines such as IL-23 and a decrease in keratinocyte hyperproliferation.

Key findings
- 01 In vitro research published in MDPI (2021) demonstrated that subtoxic micromolar concentrations effectively inhibit hyperproliferation markers like Keratin 17 and inflammatory cytokines including β-defensin 2.
- 02 Historical data from anthroposophic medicine indicates topical use of antimony salts at 0.4% for eczema, though modern safety standards typically reject this level of exposure.
Transparency
Dusting Analysis
This ingredient is not a standard cosmetic additive; any presence in a formula—even at trace amounts—is a significant safety concern due to regulatory prohibitions and its classification as a skin irritant.
The Formula
Formulation
Stability
Aqueous solutions maintain a naturally acidic pH around 4.0; however, the compound is prone to thermal decomposition, which releases toxic antimony oxides.
Conflicts
- Mineral acids
- Strong bases
- Carbonates
- Tannic acid
- Lead and silver salts
- Strong oxidizing agents
Safety
Safety Profile
Explicitly prohibited for use in cosmetics under EU Regulation 1223/2009. It is a classified Category 2 skin/eye irritant and a Category 3 oral toxin.
