How to dilute chlorophos for lice? - briefly
Mix one part 10 % chlorophos concentrate with nine parts water to create a 1 % solution, apply to the hair for 10 minutes, then rinse thoroughly. Shake the mixture well before use and wear gloves to prevent skin irritation.
How to dilute chlorophos for lice? - in detail
Chlorophos must be reduced to a safe concentration before it can be applied for lice control. The solution should contain no more than 0.5 % active ingredient, a level proven effective while minimizing toxicity to skin and respiratory passages.
Safety measures are mandatory. Wear chemical‑resistant gloves, goggles, and a mask rated for organic vapors. Perform the dilution in a well‑ventilated area, preferably under a fume hood. Keep children and pets out of the workspace.
Required items include:
- Chlorophos concentrate (usually supplied at 10 % or higher)
- Clean, temperature‑controlled water (room temperature)
- Graduated cylinder or volumetric pipette for accurate measurement
- Non‑metallic mixing container with a tight‑fitting lid
Procedure:
- Determine the final volume needed (e.g., 1 L of treatment solution).
- Calculate the amount of concentrate: Final % = (Concentrate volume ÷ Final volume) × Concentrate % → 0.5 % = (C ÷ 1000 mL) × 10 % → C = 50 mL.
- Measure 50 mL of the chlorophos concentrate using the pipette.
- Add the measured concentrate to the mixing container.
- Slowly add 950 mL of water while stirring gently to ensure uniform distribution.
- Secure the lid and invert the container several times to complete mixing.
After preparation, label the container with concentration, preparation date, and hazard warnings. Store the diluted solution in a cool, dark place and use it within 24 hours. Apply the solution to hair and scalp according to the product’s instructions, ensuring thorough coverage. Rinse after the recommended exposure time, then wash hair with a mild shampoo.
Common issues:
- Over‑dilution reduces efficacy; verify measurements before mixing.
- Inadequate stirring creates pockets of higher concentration; ensure complete homogenization.
- Exposure to open air for extended periods degrades the active ingredient; keep the container sealed when not in use.
Adhering to these steps yields a consistent, low‑risk preparation suitable for effective lice eradication.
