Applications
CAS 814-71-1 is a key reducing agent and depilatory active, widely used in cosmetics, pharmaceuticals, and industrial chemistry. In cosmetics, it’s the primary ingredient in chemical hair removers (depilatories), breaking disulfide bonds in keratin to dissolve hair shafts; also used in hair perms/straighteners as a reducing agent. In pharma, it acts as a chelating agent for heavy metal detoxification and a stabilizer in formulations. Industrially, it’s used in metal surface treatment (removing rust/oxide), textile processing (wool shrink-proofing), and organic synthesis (sulfhydryl group donor for thiol compounds). It’s also a research reagent in biochemistry for protein disulfide bond reduction.
Safety Information
Classified as GHS07 (Xn, Harmful/Irritant); hazard statements H302 (Harmful if swallowed), H315 (Skin Irritation), H319 (Eye Irritation), H335 (Respiratory Irritation).
- Inhalation: Dust irritates nose/throat; use fume hood + dust mask.
- Skin Contact: Causes redness/itching; may trigger allergy; wear nitrile gloves, wash with soap/water.
- Eye Contact: Severe irritation (tearing, pain); wear safety goggles, rinse ≥15 min.
- Ingestion: Harmful (LD50 oral rat ~1,500 mg/kg); do not induce vomiting, seek medical help.
- Chemical Hazards: Stable dry; avoid strong oxidants, acids, high temp (>60 °C) (releases toxic H?S); oxidizes on exposure to air.
- Storage: Sealed, cool/dry/dark; separate from oxidizers/acids.
- Disposal: Hazardous waste per local rules; neutralize with oxidizer before discharge.
