Product Name: Hydrocortisone Butyrate
Chemical Formula: C25H34O6
Synonyms: Hydrocortisone 17-butyrate, 11β,17-Dihydroxy-3,20-dioxopregn-4-en-21-yl butyrate
Appearance: White to off-white crystalline powder
Odor: Odorless
People recognize this chemical from prescription creams, usually as a topical corticosteroid. Its identification matters since confusion with other steroids or similar-looking compounds could lead to practical safety risks.
Classification: Not classed as hazardous under most current regulations for routine handling; risk grows with large-scale use or accidental ingestion.
Hazard Statements: May irritate eyes, skin, and respiratory tract. Systemic absorption from significant exposure can impact the adrenal axis.
Risk of Overexposure: Allergic skin reactions, hormone suppression, delayed wound healing, and increased risk for secondary infections.
People rarely think of topical steroids as dangerous, but their side effects start with how much gets absorbed through skin and accidental exposure. Regulatory bodies keep an eye on misuse, especially in lab handling and disposal.
Active Ingredient: Hydrocortisone butyrate (CAS No. 13609-67-1).
Purity: Pharmaceutical forms use over 98% pure compound.
Few additives outside of finished medical formulations; most chemical forms remain just the pure active. Ingredient transparency helps workers track exposures and manage accidental contact better.
Inhalation: Move to fresh air. Persistent symptoms call for medical attention.
Skin Contact: Remove contaminated clothing. Wash skin thoroughly with soap and water. Seek attention if irritation or rash develops.
Eye Contact: Flush eyes with copious amounts of water for several minutes. Seek medical help for ongoing discomfort.
Ingestion: Rinse mouth. Drink water for dilution. Consult a medical professional, as the effects of steroid ingestion shift dramatically depending on dose and personal health.
Accidents happen often because people don’t treat pharmaceuticals as chemical hazards. Quick first aid knowledge makes a difference, especially with routine lab tasks.
Suitable Extinguishing Media: Water spray, foam, dry chemical, carbon dioxide.
Hazards from Combustion: Fire may produce irritating or toxic vapors such as carbon oxides.
Protective Equipment: Standard gear: self-contained breathing apparatus and full protective clothing.
Small research labs rarely see compound fires, but storage rooms with a lot of dry powders or mixed substances can ignite if not kept cool and ventilated. Watching out for poorly labeled containers helps reduce those risks.
Personal Protection: Gloves, goggles, lab coat or apron.
Spill Cleanup: Avoid dust formation. Collect with damp cloth or absorbent. Clean area with water.
Environmental Protection: Prevent bulk material from entering drains or waterways, as hydrocortisone butyrate can disturb aquatic organisms.
Quick spills happen, especially in compounding pharmacies and research labs. People sometimes underestimate how easily dust or small amounts can travel, so vigilance and prompt cleanup matter a lot.
Handling: Work in a well-ventilated area, avoid inhalation, skin, and eye contact. Carefulness with dispensing, especially where people eat or drink.
Storage: Store in a tightly closed container, away from light, heat, and moisture. Keep separate from incompatible materials like strong oxidizers.
Pharmacies and clinics learn quickly how careless storage or rough handling can ruin a batch or create cross-contamination, so regular checks and clear labeling are a daily routine.
Engineering Controls: Use in fume hoods or well-ventilated spaces.
Personal Protective Equipment: Gloves, safety goggles, protective clothing whenever handling large quantities.
Respiratory Protection: Not usually needed except with risk of dust or aerosols.
It surprises people how little it takes for corticosteroids to start suppressing local immunity, especially for techs handling powders day in and out. Proper glove use and washing up prevent inadvertent exposure.
Molecular Weight: About 430.53 g/mol
Melting Point: Around 220°C
Solubility: Practically insoluble in water, soluble in alcohol, acetone, chloroform
Appearance: White to off-white powder
Odor: None detectable
Long shelf life in dry, dark storage; likes to cling to glassware and surfaces, making accurate measuring tricky, especially for high-dilution work.
Chemical Stability: Stable in standard storage conditions. Degrades with heat, light, acid, and oxidizers.
Hazardous Reactions: Combustion can release toxic fumes. Avoid mixing with strong oxidizers or acids.
Unexpected breakdown products don’t usually appear unless the compound’s stored carelessly. Routine environmental monitoring in manufacturing spots any stability problems before they spread.
Acute Effects: Irritation to skin, eyes, respiratory tract. High or chronic exposure: Cushing’s syndrome, adrenal suppression, disturbance to glucose metabolism.
Chronic Effects: Prolonged skin contact or misuse can thin the skin, increase infection risks, and disrupt hormone systems.
Routes of Exposure: Inhalation (powder), skin absorption, swallowing.
Scientific studies underline the real risks outside of usual prescribed doses—technicians, pharmacists, and even patients handling lots of topical steroids can experience side effects usually chalked up to accidental overexposure.
Aquatic Toxicity: Harmful to aquatic life in concentrated spills; corticosteroids persist in water and can impact aquatic organism development.
Persistence and Degradability: Biodegradation occurs slowly; substances like this compound, along with similar pharmaceuticals, turn up in water treatment effluent.
Every pharmacy, hospital, and lab contributes to drug residues found downstream. Doubling down on waste tracking keeps more of these synthetics out of the ecosystem.
Waste Handling: Treat as pharmaceutical waste. Safe disposal relies on incineration or licensed hazardous chemical disposal.
Container Disposal: Rinse and dispose as hazardous waste according to regulations.
Dumping down the drain or general trash stays a problem worldwide—sometimes from lack of awareness, sometimes due to lax rules. Coordinating with local waste programs and staff education keeps these compounds away from water supplies.
UN Number: Not regulated for road, air, or sea transport in small quantities commonly handled in healthcare and laboratories.
Outside routine shipping in bulk, most transport incidents happen from poorly packed, leaking containers, especially in fieldwork or while moving between facilities. Secondary containment and proper labeling help reduce those errors.
Regulation: Hydrocortisone butyrate faces different legislative hurdles in pharmacies and chemical supply chains—often requiring tracking as a prescription medication, sometimes as a controlled ingredient.
Workplace Exposure Limits: No established OSHA or ACGIH exposure limits, but many institutions set their own conservative in-house limits.
Keeping up with evolving pharmaceutical waste rules protects both workers and the environment. Staff education and policy reviews ensure changing guidance gets applied before outdated practices harden.
