(Benzalkonium Chloride)

Ingredient: BKC (Benzalkonium Chloride) 86%

Veterinary Indications

BKC 86% (after dilution) is mainly used for topical disinfection (not for systemic

administration) in livestock, poultry, companion animals (dogs, cats), and aquaculture. Its core indications include:

Animal Category	Specific Indications
Livestock (cattle, sheep, pigs)	– Disinfection of skin wounds, abrasions, and burns.- Sanitization of teat skin (pre/post-milking to prevent mastitis).- Disinfection of surgical sites (preoperative skin preparation).- Cleaning of contaminated skin from manure, dirt, or mild bacterial infections.
Poultry (chickens, ducks)	– Disinfection of skin lesions caused by bacterial/fungal infections (e.g., fowl pox secondary infections).- Sanitization of hatching eggs (low-concentration soaking to reduce egg-borne pathogens).- Disinfection of footpad dermatitis in broilers.
Companion Animals (dogs, cats)	– Topical disinfection of minor cuts, scratches, or hot spots (moist eczema).- Cleaning of ear canals (as part of ear cleaners for mild bacterial/fungal otitis externa, diluted with ear-friendly solvents).- Disinfection of skin folds (e.g., in Bulldogs, Pugs) to prevent bacterial overgrowth.
Aquaculture (fish, shrimp)	– Disinfection of fish eggs (to reduce fungal infections like Saprolegnia).- Treatment of superficial bacterial infections in fish (e.g., fin rot, body slime disease) via bath immersion.- Sanitization of aquaculture equipment (tanks, nets) to prevent pathogen transmission.

Veterinary Dosage & Dilution Guidelines

The 86% BKC concentrate is highly potent—incorrect dilution can cause skin/ mucosal irritation, chemical burns, or even toxicity. Dilution ratios depend on the animal species, target use, and desired working concentration. Below are standard dilution and application protocols:

Key Principle:

First, calculate the required dilution factor to achieve the target working concentration (usually 0.01%–0.1% for most veterinary uses).Example: To make 1L of 0.05% working solution from 86% BKC:Dilution factor = 86% ÷ 0.05% = 1720x → Add 0.58 mL of 86% BKC to 999.42 mL of solvent.

Animal Category	Target Working Concentration	Dilution Ratio (86% BKC : Solvent)	Application Method
Livestock	0.05%–0.1%	1:1720 to 1:860	– Wound/teat disinfection: Soak gauze in solution and wipe the area (2–3x daily).- Surgical prep: Wipe the surgical site 2–3 times, let air dry.
Poultry	0.02%–0.05%	1:4300 to 1:1720	– Egg disinfection: Soak clean eggs in solution for 5–10 minutes (avoid prolonged soaking).- Skin lesions: Spray diluted solution (avoid spraying eyes/nasal cavities).
Companion Animals	0.01%–0.05%	1:8600 to 1:1720	– Skin wounds: Dab solution with a cotton swab (1–2x daily).- Ear cleaning: Mix with equal parts glycerin (to reduce irritation), apply 2–3 drops, massage ear, and wipe excess.
Aquaculture	0.005%–0.01% (fish); 0.01%–0.02% (equipment)	1:17200 to 1:8600 (fish); 1:8600 to 1:4300 (equipment)	– Fish bath: Immerse fish in solution for 15–30 minutes (monitor for stress).- Equipment: Soak or spray equipment, let sit 10–20 minutes, rinse with water before use.

Storage

Storage Aspect	Requirements
Container	Store in a tightly sealed, chemically resistant container (e.g., HDPE plastic or glass). Avoid metal containers (BKC reacts with aluminum, iron, etc.).
Temperature	Keep in a cool, dry place at 15°C–25°C (59°F–77°F). Do NOT expose to extreme heat (above 40°C/104°F) or freezing (below 0°C/32°F)—freezing can cause precipitation and loss of activity.
Light	Protect from direct sunlight or UV radiation (light accelerates BKC degradation). Store in an opaque container or a dark cabinet.
Compatibility	Do NOT store near anionic surfactants (e.g., soaps, some detergents), acids, or oxidizing agents (e.g., hydrogen peroxide)—they neutralize BKC’s activity.
Accessibility	Keep out of reach of children, non-veterinary staff, and animals. Label clearly with “Veterinary Use Only,” “Concentrated—Toxic if Undiluted,” and expiration date.
Shelf Life	Unopened: 2–3 years (per manufacturer’s label). Opened: Use within 6 months (moisture absorption reduces potency). Discard if the solution turns yellow/brown or develops a foul odor.
