How Do You Add Fragrance Oil to Liquid Soap?

Liquid Soap is a wonderfully versatile product that we mostly all use multiple times a day and that can be found in several applications throughout the house. Everything from hand pumps at the kitchen and bathroom basin, body wash in the shower, pour bottles for washing the dishes, clothes and floor just to name a few. The common factor these products all share, other than the fact that they are all cleaning agents for various personal and home uses, is fragrance.

If you are familiar with making soap from scratch, you would no doubt be aware that solid soap is made with sodium hydroxide and that liquid soap is made with potassium hydroxide (KOH). Both substances are relatively similar however, potassium hydroxide has the ability to make soft soap and when combined together with water, liquid soap is then formed.

The best fragrance for soap making can be either natural essential oils or fragrance oils, depending on your use. How much fragrance in soap will be contingent upon several other factors such as the type, manufacturer, purpose etc.
