This chart shows exactly how much Lye (Sodium Hydroxide) you should use in order to saponify a specific fat or oil used for cold process soap making! It also demonstrates the advantages of each oil so you can create the perfect oil combination for your handmade soaps.
|Harsh?||Fluffy Lather||Stable Lather||Skin Care|
|Grape seed Oil||193||Soft||2||–||Yes||4|
SAP – This column is the saponification value (SAP value), it shows how many milligrams of lye (sodium hydroxide) are needed to saponify exactly 1 gram (1000 milligrams) of the fat or oil in question.
Hard/Soft – This is to show whether the oil will produce a hard or soft bar. If the bar is too soft your soap will dissolve prematurely, too hard the soap will not lather. Be sure to mix a hard and soft oil to create a balanced soap bar.
Harshness – This column shows how well the oils clean. Bear in mind all soaps are good cleansers; some are harsher than others to the skin. 5 = Harshest, 3 = Average.
Fluffy Lather – This column specifies whether the oil produces a fluffy and bubbly lather. If the oil creates a fluffy lather be warned it also washes away much easier.
Stable Lather – A stable lather has much less substance then a fluffy lather, but is more difficult to wash away. The key is to combine the correct oils to find a suitable lather balance.
Skin Care – This shows how beneficial the soap is to the skin. This takes into consideration the abundance of anti-oxidants in the oil, the availability of vitamins and the moisturising properties.
3 = Moderate benefits to the skin, 5 = Very beneficial to the skin.
