The lye to water ratio of the lye solution is roughly 1 part lye to 2.3 parts water. This is equivalent to roughly 30% lye and 70% water.
How do you calculate lye and water for soap making?
Calculating and Measuring Water (Amount of Fat) × (Saponification Value of the Fat) = (Amount of Lye) (Amount of Lye) ÷ 0.3 = (Total Weight of Lye Water Solution) (Total Weight of Lye Water Solution) − (Amount of Lye) = (Amount of Water).
How much water does it take to dissolve soap?
Add 1 cup of warm water for every bar of soap and stir the solution.
How do you calculate soap ingredients?
Calculating the Amount of Soap Needed to Fill a Soap Mold Calculate the volume of the mold in cubic inches. Multiply the volume of the mold by 0.4 to find the total amount of oils in the recipe. Enter that amount of oils into an online lye calculator to get the final recipe quantities.
What happens if I add too much water to soap?
Too much water in a recipe can also result in a soft bar of soap. Adding sodium lactate to lye water helps soap harder faster.
How do you calculate lye concentration?
If you would like to create a 33% solution instead, you would multiply 3.5 ounces x 2 = 7 ounces of water. If you know you need 2 ounces of lye (because your lye is determined by your oils), and want to use a 25% lye solution, you would simply multiply your lye amount by 3 to find your water amount.
How much lye do you put in soap?
If using more liquid oils in your soap, though, superfatting over 10% is probably going to result in a soft bar of soap that isn’t as cleansing. The default in the Soapcalc lye calculator is 5%. I think 5-8% is a good range to play with, depending on what type of soap you are making.
Will soap dissolve in water?
Generally speaking, soaps remove dirt and fats by making them soluble in water. Because of the two different parts of the molecule, a soap molecule is soluble in water and at the same time can dissolve fats.
What percentage of soap is water?
Most soap recipe calculators are set to a default of “38% water as % of oils.” This means a soap recipe will have 38 grams (or 38 ounces) of water for every 100 grams (or 100 ounces) of fats.
How do you calculate soap percentage?
Divide each individual weight by 44 to get the percentage of each oil in the recipe. Let’s say you want to make a 7-pound (or 112-ounce) batch of soap. (Remember, that’s just the measurement of your oils.
How do you Rebatch soap with too much water?

Why is my soap not hardening?
Too much extra liquid (milk, purees, etc.) on top of the water in the lye solution causes soap to not harden correctly. If soap goes through gel phase, it becomes harder faster. If using a silicone or plastic mold for cold process soap, use sodium lactate.
How do you calculate lye to water ratio?
The lye to water ratio of the lye solution is roughly 1 part lye to 2.3 parts water.
What is the molarity of lye?
40 g of NaOH is equal to 1 mole. 1 g of NaOH will be equal to 1 40 moles. Therefore, we can say that 1 liter of sodium hydroxide solution contains 18.9375 moles or in other words molarity of 50% (w/w) Sodium Hydroxide is equal to 18.9375 M.
How do you make lye solution?
Instructions Weigh the Water. To begin, put on your safety goggles and rubber gloves, and make sure your work space has good ventilation. Weigh the Lye. Place the mason jar on the scale, and zero out the weight. Add the Lye to the Water. Stir the Lye and Water Mixture. Set the Lye Solution in a Safe Place to Cool.
What is the best lye concentration in soap making?
Any soap recipe can be made using a 50% lye solution, but most soapers prefer to use more water. Some soapers make a “masterbatch” lye solution using a 50% alkali concentration.
What temperature should lye and oil be mixed?
For most soapers, the preferred temperature of soaping lye and oils are 120-130 ° F. In addition, many soapers and books believe it is helpful to have the lye and oil within 10 degrees of each other. The temperature range of 120-130 ° F is popular for several reasons.
Does soap dissolve in water Yes or no?
Soap cleans oil and grease because one end of the soap molecule is polar and so is soluble in water, and the other end is non-polar and so similar to oil and grease. The soap molecules surround the grease leaving the water-soluble parts on the outside so the water can help wash the grease away.
Will a bar of soap dissolve in the toilet?
You can also chop a bar of soap into small pieces and place it in the toilet bowl. Carefully pour the hot water into the toilet bowl to dissolve the liquid or bar soap. The soap should quickly begin to unclog the toilet drain by helping the clogged object start sliding down the pipes. Repeat the process, if necessary.
Which soap is insoluble in water?
Because they are negatively charged, soap micelles repel each other and remain dispersed in water. Grease and oil are non>polar and insoluble in water. These fatty acids are less soluble than the sodium or potassium salts and form a precipitate or soap scum. Because of this, soaps are ineffective in acidic water.
What is 10 water discount in soap making?
You can use a discount any time you want to speed up the soap making process. We also recommend it if your recipe contains additives with extra liquid. A 10% discount with a couple ounces of pumpkin, aloe, apple, etc. will ensure your batch isn’t too wet.
Do you add lye to water or water to lye?
Always Add Lye to Water (Never Water to Lye!): When mixing water and lye the first step is to measure the correct amounts into separate containers. Once you have the correct amounts for your recipe, the lye should be slowly added to the water. NEVER add water to your lye!Jul 20, 2015.
