Step 2: Soap recipe and fabrication

Picture of Soap recipe and fabrication
First I will give you the base recipe for one liter of used cooking oil.

1 liter of used cooking oil
200 grammes of caustic soda (NaOH)
400 milliliters of warm water
40 milliliters of softener for clothes

1. mesure the cooking oil and put on a recipient after filtering impurities out
2. mesure the water
3. weight the caustic soda
4. dissolve the caustic soda with the water (use mask, glasses and protection gloves because the mixture will boil and release toxic gases)
5. join the mixture with the oil
6. stir 15 minutes with a wooden spoon, until the prepared becomes consistent and put the softener for clothes to give the soap softness and fragrance

Thankyou for the recipe for used cooking oil.

One caution: lye (caustic soda) should never be put in hot water. Use very cold water instead of warm. It will still get very hot as the water and lye react.

What is a recipient?

Friendly note to the readers. ALWAYS pour the lye crystals into the water and not the other way around - for safety reasons. It is shown correctly but I wanted to really emphasize this. If the lye in the water becomes a hard clump, no worries, GENTLY keep stirring and it will dissolve.
