Using Salt To Thicken Soap

Sometimes soap-makers wish to thicken their organic soap bases. Here’s how to do it with a salt solution:

Weight/Weight - In this example, we will show how much salt is needed to make a 25% salt solution using weight as our measurement for water.

To make 100 grams of a 25% salt solution, you would dissolve 25 grams of salt in 100 grams of water.  

Weight/Volume – In this example we show how much salt is needed to make a 25% salt solution using volume as our measurement for water.

To make a 25% salt solution using volume as our measurement, dissolve 25 g salt in 100 ml water.

To be sure that much salt will dissolve, first heat the water. Add the salt and stir.

Using your finished salt solution at a 4% usage rate should thicken your soap. This means that if you have 1000 ml of the soap, 40 ml of the salt solution is needed to thicken it.

When adding the solution to the heated organic soap base, add a small amount at a time while stirring it until the organic soap base thickens.
