GOST/CAS:
CAS 633-03-4 / ГОСТ 8153-73
Brilliant Green is a highly effective synthetic antiseptic and disinfectant agent belonging to the triphenylmethane dye group. It comes in the form of a fine crystalline powder or shiny, golden-green to green clumps that are highly soluble in water and ethanol. Due to its potent antimicrobial activity against Gram-positive bacteria and pathogenic fungi, this product is an indispensable active ingredient and raw material for manufacturing finished dosage forms, topical antiseptics, and sanitizing formulations in the modern pharmaceutical and medical industries.
Applications
Pharmaceutical Manufacturing: Used as an Active Pharmaceutical Ingredient (API) to produce the well-known 1% or 2% topical alcoholic and aqueous solutions ("Zelyonka"), antiseptic ointments, medical plasters, and surgical glues.
Disinfectant Production: Serves as a key antiseptic and marker component in formulations designed for disinfecting surfaces, medical instruments, and processing equipment in the food, beverage, and biotech industries.
Medical Diagnostics & Microbiology: Applied in laboratory practices as a selective stain for microscopy, cellular structure staining, and as an additive in the preparation of specialized culture media.
Veterinary Medicine & Aquaculture: Utilized in manufacturing antifungal and antiparasitic treatments for animal skin diseases, as well as for water sanitation in commercial fish farming.
Key Advantages
High Antimicrobial Potency: Delivers rapid and prolonged bactericidal action against Gram-positive microorganisms (including Staphylococcus and Streptococcus species), significantly outperforming many modern alternatives.
Gentle Therapeutic Effect: Unlike iodine, brilliant green solutions do not cause chemical tissue burns, do not dry out the skin, and do not inhibit tissue regeneration, making it highly valued in pediatric wound care.
Cost-Efficiency & High Concentration: The powder form features an active substance purity of over 98%, which drastically reduces logistics and storage costs while allowing manufacturers to easily adjust dosages and concentrations.
Stability & Chemical Compatibility: Dissolves flawlessly in alcohol and water bases, retaining its physical, chemical, and disinfecting properties even during long-term storage within finished product formulations.
Storage & Transportation
- Store in dry, cool, light-protected warehouses in the manufacturer's tightly sealed original packaging, away from heat sources and strong oxidizing agents.
- Recommended storage temperature range: +5°C to +25°C. Avoid sudden temperature fluctuations and high humidity (the product is hygroscopic).
- The powder has high staining properties. Always use Personal Protective Equipment (PPE) including respirators, gloves, and safety goggles during handling.
- Transportation is permitted by all types of covered transport in strict compliance with standard freight regulations. The product is non-hazardous as long as packaging integrity is maintained. Guaranteed shelf life — 3 years from the date of manufacture.
