Science
Mechanism of Action
TETRAETHYL ORTHOSILICATE functions by hydrolyzing its alkoxy groups to release ethanol molecules, followed by the condensation of unstable silanols (-Si-OH) into an amorphous silica gel. This process establishes a durable, glassy silica network, which can be engineered into nanoparticulate structures for applications like controlled release systems.

Stability
TEOS exhibits optimal stability in its hydrolyzed state within a pH range of 1.5 to 2.5, which prolongs its gelation time. Outside this narrow range, particularly between pH 5 and 6, it becomes highly unstable and rapidly gels. It slowly decomposes into silicon dioxide and ethanol upon exposure to water or atmospheric moisture.
Conflicts
- water (reacts and decomposes)
- strong acids (reacts exothermically)
- oxidizing agents (e.g., nitrates, chlorine bleaches, oxidizing acids - may cause ignition)
- alkali metals
- hydrides
Safety
Safety Profile
TETRAETHYL ORTHOSILICATE is classified as a hazardous substance, presenting as a flammable liquid and vapor. It causes serious eye irritation and may induce respiratory irritation. Direct skin contact can lead to dryness, cracking, and inflammation. Exposure of compromised skin (e.g., open cuts, abrasions) is particularly hazardous as it may facilitate entry into the bloodstream, potentially resulting in systemic injury. Ingestion carries risks of liver, kidney, and lung damage.

Verdict
Given its classification as a hazardous substance with high irritation potential, flammability, and documented risks of systemic injury, TETRAETHYL ORTHOSILICATE is deemed unsuitable for cosmetic application.
