MOLYBDIC ACID.

Avoid CAS 7782-91-4 / PRESERVATIVE

Molybdic acid is an inorganic compound primarily utilized in industrial applications. For precision skincare, research consistently indicates a lack of direct beneficial mechanisms and highlights its classification as a significant irritant.

Science

This compound does not exhibit a known direct mechanism of action that confers advantageous effects upon the skin. Instead, comprehensive data identifies Molybdic Acid primarily as an irritant to both dermal tissue and ocular structures.

Stability

Molybdic acid is highly acidic; a 1 mM solution has a pH of 3.46, decreasing to 2.94 for a 10 mM solution, and 2.43 for a 100 mM solution. Its solubility in cold water is slight (1.33 g/L at 18°C), but it becomes moderately soluble in hot water (25.68 g/L at 70°C). Solubility is significantly enhanced in alkaline solutions. Store in a dry environment at 15–25 °C with the container securely closed.

Conflicts

  • Incompatible materials (general)
  • Metals and their oxides or salts (reacts violently with chlorine trifluoride and bromine trifluoride)
  • Peroxides (requires careful control)
  • Borohydrides or cyanoborohydrides (avoid reaction)
  • Acids (reacts to form soluble molybdate salts)
  • Metals such as iron and aluminum (can be dissolved)

Safety

CIR Status
Not reviewed
Sensitization risk High

Molybdic acid presents a high risk of irritation or burns with prolonged skin exposure and can cause severe eye irritation. It may also induce respiratory irritation and potentially lead to organ damage through prolonged or repeated exposure. It is classified as an irritant. No specific Cosmetic Ingredient Review (CIR) report, Scientific Committee on Consumer Safety (SCCS) opinion, or FDA status for cosmetic use has been identified.

Our Assessment

Avoid

Due to its explicit classification as a severe irritant with no known beneficial mechanisms for skin and an unreviewed safety status for cosmetic use, Molybdic Acid is not suitable for precision skincare formulations.
