甜杏仁三重滋潤皂筆記 Notes For Avoiding Mistakes

Not happy with the texture.

Notes:

1. Use hand blender periodically. Most of the time, use a spatula or whisk to mix the batter. It won't take a long time to get trace.
2. When mixing the batter, keep the temperature between 45 to 50 degrees Celsius.  This will ensure the butters to incorporate with other oils and won't cause white spots.
3. Essential oil may cause quick trace, don't add too much.

Soap has small visible white spots all throughout:

1. Stearic Acid Spots (feel solid, smooth, waxy)

Reason: Hard fats such as palm, tallow, lard, butters, etc contain solid fatty acids (like stearic acid & palmitic acid) that need a higher temperature to melt, while other components of the fat melt more easily.

Solution: If your temperatures get too cold, the fatty acids in solid fats can start solidifying before they can react with the lye, and you can end up with stearic acid spots. Working with warmer temperatures can help in that case. If using palm oil, it’s recommended to completely melt and stir the oil every time you use it or you might have an uneven balance of fatty acids, leading to more spots in some batches.
