How do you mix kerosene with oil for lice treatment? - briefly
Combine equal parts of high‑purity kerosene and a light mineral oil, mix thoroughly until a uniform emulsion forms, then apply the solution to the scalp, leaving it for a few minutes before rinsing thoroughly. Use protective gloves and work in a well‑ventilated area to avoid inhalation and skin irritation.
How do you mix kerosene with oil for lice treatment? - in detail
When preparing a kerosene‑oil solution for lice eradication, follow a precise protocol to ensure efficacy and safety.
Begin by selecting a high‑grade, low‑sulfur kerosene and a pure vegetable oil such as olive or sunflower oil. Both liquids must be at room temperature; cold kerosene thickens and reduces penetration, while hot oil may cause burns.
Measure the components with a calibrated graduated cylinder. A commonly used ratio is 1 part kerosene to 2 parts oil by volume (e.g., 30 ml kerosene mixed with 60 ml oil). Adjust the proportion only after confirming tolerance in a small skin patch test.
Transfer the measured oil into a clean, dry glass or high‑density polyethylene container. Add the kerosene slowly, stirring continuously with a stainless‑steel spoon or a magnetic stirrer. Continue mixing for 2–3 minutes until the mixture appears homogenous, with no visible separation.
Before application, perform a patch test on a limited area of the scalp. Apply a small quantity, leave it for 5 minutes, then rinse thoroughly. Observe for irritation, redness, or allergic reaction. If none occur, proceed to full treatment.
Apply the solution to dry hair using a spray bottle or a cotton applicator, ensuring thorough coverage from roots to tips. Allow the mixture to remain on the scalp for 30–45 minutes; during this period, cover the head with a plastic cap to prevent evaporation.
After the exposure time, rinse the hair with warm water and a mild shampoo. Repeat the process after 7–10 days to break the lice life cycle.
Dispose of any leftover mixture in a sealed, labeled container. Store the prepared solution in a cool, well‑ventilated area away from open flames or heat sources, as kerosene is flammable.
Document the batch details (date, quantities, lot numbers) for future reference and compliance with safety regulations.
