How to properly dilute kerosene for lice treatment? - briefly
Combine one volume of kerosene with three volumes of water, stirring until a stable emulsion is achieved; apply to the infested hair, let act for 10–15 minutes, then rinse completely.
How to properly dilute kerosene for lice treatment? - in detail
Kerosene must be handled as a hazardous liquid. Prepare the solution only in a well‑ventilated area, wearing chemical‑resistant gloves, goggles, and a disposable protective suit.
- Choose a non‑reactive container (glass or high‑density polyethylene) with a tight‑closing lid.
- Measure the kerosene with a calibrated syringe or graduated cylinder.
- Add a carrier oil (e.g., mineral oil, coconut oil, or jojoba oil) to achieve a 10 % kerosene mixture:
- 10 ml kerosene + 90 ml carrier oil = 10 % solution.
- For larger batches, keep the same ratio (1 : 9).
- Seal the container and shake vigorously for 30–60 seconds until the liquids are uniformly dispersed.
- Transfer a small amount to a clean applicator bottle with a narrow tip.
Before full application, perform a patch test on a small skin area for 15 minutes. Observe for redness, burning, or irritation; discontinue use if any reaction occurs.
Application procedure:
- Apply the diluted mixture to dry hair, concentrating on the scalp and hair shafts where lice reside.
- Use a fine‑toothed comb to distribute the liquid evenly and to mechanically remove lice and nits.
- Allow the solution to remain for 10–15 minutes, avoiding prolonged exposure that increases skin irritation.
- Rinse thoroughly with lukewarm water and a mild, non‑oil‑based shampoo.
- Dispose of used applicators and gloves in a sealed plastic bag; wash hands and any reusable equipment with soap and water.
Safety considerations:
- Kerosene is flammable; keep away from open flames and heat sources during preparation and use.
- Do not use on broken skin, mucous membranes, or in children under two years of age.
- Store the mixture in a locked, cool cabinet, clearly labeled, and out of reach of children and pets.
- Seek medical advice if symptoms persist or if an allergic reaction develops.
The described protocol provides a controlled 10 % kerosene solution suitable for short‑term lice management, while minimizing the inherent risks of the chemical.
