Soap making Oils and their Characteristics

Terms:

Saturated Fat - Oils that make a hard soap. Usually come in a solid form and need to be melted before using. Coconut Oil , Cocoa Butter and Palm Oil are examples.

Scenting Oils - There are two types of scenting oils, fragrance oils, which are man-made and contain alcohol and essential oils which are natural. The alcohol in fragrance oils tends to cause problems in soap making so essential oil's are normally used in soap making. Essential Oil's are more costly and harder to find than Fragrance Oil's but have better scent retention and will not ruin a batch of soap. The only time fragrance oils can often be used safely is at the trace stage or during rebatching. Essential oils can be added at trace or in the base oil.

Superfatting Soap - This means that oils or fats have been left in the soap unconverted by the lye either because the amount of lye was decreased to allow some fat/oil to remain or oil/fat was added at the trace stage after the mix had saponified. (In lay terms saponification means that the lye/water and oils have been mixed and brought to a trace stage where at this point the lye has been mostly neutralized. Any oil added at this stage will basically remain unchanged in the final soap bar) The method of adding additional fat to the soap mixture after it has saponified had an advantage in that it allows the soap maker to better control what oil is left in the soap. Adding the extra oil at this time keeps it in its natural state, and ready to instantly moisturize your skin as you use the soap. When superfatting your soap at the trace stage make sure you use the 1% excess fat lye amount. Otherwise the soap will be too oily because it will not only contain the oil you add at the trace stage but will also have excess fat from a lack of lye.

Superfatting soap by decreasing the lye content eliminates the step of adding oil at trace but decreases the control that the soap maker has over what oil is left in the soap. For example, if 5% cocoa butter was added as part of the base oil (say 95% Olive Oil) and the lye amount was calculated for a 5% excess fat level the excess fat in the soap would be made up of a combination of Olive oil and cocoa butter with most of the excess fat being Olive oil. If the same batch was mixed using just Olive Oil at a 1% excess fat level and the cocoa butter was added at the trace stage you would know that the final soap bar contained 1% olive oil and 5% cocoa butter. The cocoa butter would have in this case been unaffected by the lye since it was added after the soap had traced.

(NOTE - When adding oils at the trace stage (superfatting) be sure to use a lye calculatation that gives you about 1% excess fat. When using our Soap-Calc program or any other lye calculator do not include the oils that you will be adding at trace in the calculation)

Trace - The point at which the soap/lye mixture begins to thicken. At this point the solution is about 80-90% saponified and essential oils, superfatting oils, soap colors , additives, etc can be added without their characteristics being changed substantially by the saponification process.

Unsaturated Fat - Oils that are in a liquid form. They need to be mixed with saturated fats at the base oil stage in order to create a hard bar.

Castor Oil
Castor Oil is often used to superfat. It attracts and holds moisture in the skin. Use it in combination with other vegetable oils to produce a nice hard bar of soap. You can add a bit at trace for superfatting or add it to other oils at a rate of no more than 30% in the beginning of the soapmaking process.


Cocoa Butter
Cocoa Butter is used to make soaps harder. When used in soap as a superfatting oil it acts to lay down a protective layer which holds the moisture to the skin, so it is an excellent skin softener. It has a natural chocolate scent but it is also available in unscented versions. You can use it from anywhere about 1 ounce to a pound at trace, to 15% of your total base oils, depending on your preference.


Coconut Oil
Coconut Oil makes soaps lather beautifully but can be drying when it makes up a large portion of your soap's fats. It will make a very hard, white bar of soap with abundant lather.

Jojoba
Jojoba helps to promote a stable lather and is good at conditioning skin. Because of its expense, it's usually used to superfat soap batches or in shampoo bars.

Vegetable Shortening or Soybean Oil
Vegetable shortening is normally made out of Soybean Oil . It is cheap and readily available and produces a mild, stable lather. Use it in combination with other exotic or moisturizing oils.

Use vegetable shortening as a base oil or combine it with other, harder oils for better results. Recommend use as base up to 50% of total oils.


Sunflower Oil
Sunflower Oil is a less expensive alternative to olive oil. It contains Vitamin E, so it naturally resists going rancid (Vitamin E is a preservative). Despite that, don't store it longer than six months. It is a less saturated oil so you want to combine it with other, more saturated, oils -- try to avoid using more than about 15-20% sunflower oil. It can make your soaps take longer to trace and to harden. Use as a Base oil up to 20%


Wheat Germ Oil
This oil is thick, sticky and antioxidant. It's also very rich in vitamin E. Can be used to nourish dry or cracked skin and soothes skin problems such as eczema and psoriasis.
