DECAHYDRO-4,8,8-TRIMETHYL-9-METHYLENE-1,4-METHANOAZULENE/FORMIC ACID/BORON TRIFLUORIDE.

Avoid CAS 68855-38-9 / PERFUMING

This complex is a reaction product involving Formic acid, Boron Trifluoride, and Longifolene. Primarily recognized for its aromatic properties, there is no documented mechanism of action or direct skincare benefit for this compound. Its constituent components, however, present significant safety concerns regarding dermal exposure and general handling.

Summary

Science

Mechanism of Action

Direct mechanisms for skin benefits have not been established for this complex. Its primary utility, if incorporated, would be related to its aromatic qualities, which are attributed to its Longifolene component. The Boron Trifluoride constituent functions as a potent Lewis acid and catalyst in chemical reactions, but its interaction with skin for beneficial outcomes is uncharacterized.

Stability

Boron Trifluoride, a key constituent, maintains stability in dry atmospheres but is highly reactive with water, undergoing slow hydrolysis. The overall reaction product is classified as a flammable liquid and vapor, and its complexes with flammable solvents can significantly elevate fire risk.

Conflicts

  • Boron Trifluoride reacts violently with alkali metals (e.g., lithium, sodium, potassium)
  • Boron Trifluoride reacts violently with alkyl nitrates (e.g., amyl nitrate, butyl nitrate, nitrocellulose)
  • Boron Trifluoride reacts violently with calcium oxide
  • Boron Trifluoride reacts violently with lime (calcium hydroxide)
  • Boron Trifluoride attacks many metals in the presence of water
  • Boron Trifluoride will polymerize unsaturated compounds

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk High

This specific reaction product has not undergone assessment by the Cosmetic Ingredient Review (CIR) or the Scientific Committee on Consumer Safety (SCCS), nor does it have specific FDA status. Its Boron Trifluoride component is a highly corrosive gas, toxic via inhalation, causing irritation and burns upon dermal contact. Prolonged exposure can lead to irritation of the nose and throat, dryness, and nosebleeds. Longifolene, another component, possesses intrinsic dermal sensitization properties, leading to restrictions in its use as a fragrance ingredient.
