Types of Homemade Soap
Homemade soap falls into one of three categories: cold processed, hot processed, and rebatched. Cold processed soap is formed by pouring the 'raw' soap into molds. It tends to be smoother in texture than the other kinds of soap and last longer. It also takes longer to cure. When hot processed soap is formed, extra heat is added to the 'raw' soap. The texture is less smooth but the soap takes less time to cure. Rebatched soap is produced when previously made soap is melted down, often to add fragrance or herbs. Rebatching is a great way to add delicate herbs, but it adds additional time to the soap making process.
What is Superfatting?
The process of making soap, called soapfonication, mixes oils with lye and water to create the soap molecule. Sometimes extra oils are added, called superfatting. These extra oils allow the soap to be more moisturizing but they also decrease the lather of the soap and it's shelf life. It also makes the soap softer. Vitamin E can be added to extend the shelf life of the soap and enrich the skin. The extra oils often feel like a 'film' on the skin. They often absorb. A person with dry skin can benefit from a soap that is superfatted. Superfatting is expressed as a percentage; lower percent means less moisturizing oils, higher percent means more moisturizing oils.
People with sensitive skin often benefit from homemade soap. Homemade soap is usually made without the preservatives that cause irritation. For people with very sensitive skin, homemade soap can also be made with dyes and fragrances. The addition of oatmeal and honey into soap also seems to sooth sensitive skin. Children and babies usually do well with unscented soap. Please keep in mind, homemade soap does not contain the numbing agents that are added to commercially available baby soap, so please keep homemade soap out of eyes.
Keep it Dry
Homemade soap can become soft and sticky if it's allowed to sit in water. After using soap, place it on a dry wash cloth or a special soap deck to allow it to dry between uses. This will extend the life of the bar. I put our hand soap on a dry face scrubby to keep it from getting stuck to the counter. Of course, I change the face scrubbie at least once a week to reduce the chance of bacteria growing in the scrubbie.
Soap, when used properly, has natural antibacterial properties. When you wash your hands, sing the alphabet song while you lather to ensure you've washed long enough to kill germs. Soap makers can add tea tree oil to natural soap to increase it's antibacterial properties. Tea Tree Oil soap is a great alternative to commercially produced antibacterial soap that is often harsh and drying.
Soap makers will occasionally add exfoliating agents to soap. Cocoa powder, coffee grounds, oatmeal are all natural and gentle ways to remove dead skin. If you suffer from 'chicken skin' or patches of rough skin, try out an exfoliating bar.
