How to dilute kerosene for lice treatment? - briefly
Combine kerosene with a non‑flammable diluent (e.g., water or a mild carrier oil) at a ratio of about 1 part kerosene to 3–4 parts diluent, stirring thoroughly. Apply the mixture to the scalp, leave for 10–15 minutes, then rinse completely.
How to dilute kerosene for lice treatment? - in detail
To create a safe and effective kerosene solution for lice eradication, follow a precise dilution protocol, use appropriate equipment, and observe strict safety measures.
Begin by selecting a clean, glass or high‑density polyethylene container with a tight‑fitting lid. Measure the required amount of petroleum distillate using a calibrated graduated cylinder. A commonly recommended concentration for topical application is 5 % kerosene by volume; this translates to 5 mL of kerosene mixed with 95 mL of a carrier such as distilled water or a mild, non‑ionic surfactant solution.
The preparation steps are:
- Pour the measured kerosene into the container.
- Add the carrier fluid slowly while stirring continuously with a glass rod or a disposable stir stick.
- Continue mixing until the mixture appears homogeneous, typically 30–60 seconds.
- Seal the container and label it with concentration, date of preparation, and hazard warnings.
Safety precautions:
- Perform the dilution in a well‑ventilated area away from open flames or sparks.
- Wear nitrile gloves, goggles, and a protective apron to prevent skin and eye contact.
- Keep the mixture out of reach of children and pets.
- Discard any excess solution according to local hazardous waste regulations; do not pour down drains.
Application guidelines:
- Apply a thin layer to affected hair and scalp using a disposable brush or cotton applicator.
- Allow the solution to remain for 5–10 minutes, then rinse thoroughly with warm water and a mild shampoo.
- Repeat the treatment after 7–10 days to target newly hatched lice.
Storage instructions:
- Store the prepared solution in a cool, dark place at temperatures below 25 °C.
- Use within 30 days; potency declines after this period.
Adhering to these detailed steps ensures a consistent dilution, minimizes health risks, and maximizes the likelihood of successful lice control.
