Cold Process Soap Stearic Acid Usage
On the Usage of Stearic Acid in Cold Soap
Soap, used in ancient times to purify the body. Cold soap, unique process, retention of natural nourishment, favored. The use of stearic acid in cold soap is quite particular, related to the quality and properties of soap. This article describes its usage in detail to help soap makers get exquisite products.
1. Characteristics of Stearic Acid
Stearic acid, white or yellowish flakes at room temperature, lumps, with a fine texture. It is a saturated fatty acid, chemically stable, and can affect the structure and properties of soap during the soap making process. This substance can increase the hardness of the soap, make the soap stable and not easy to deform; it can also improve the foam properties of the soap, make the foam rich and dense, and improve the feeling of use.
Second, the time to add stearic acid in cold soap
In the process of cold soap making, the saponification reaction between alkali and oil is the key. The time to add stearic acid should be carefully grasped. In the early stage of mixing grease and alkali, the temperature is still high, so it is not advisable to add stearic acid urgently at this time. Due to excessive temperature or excessive reaction of stearic acid, the saponification balance can be affected. When the temperature of the soap solution drops to a suitable range, about 40-50 degrees Celsius, stearic acid can be slowly added. This temperature can not only fully melt the stearic acid and disperse evenly in the soap solution, but also
3. Dosage of stearic acid Control the amount of stearic acid used in
, which has a great impact on cold soap production. If the dosage is too small, it is difficult to achieve the desired effect, such as insufficient hardness of the soap body and poor foam. However, if the dosage is too much, the soap body may be too hard, dissolve slowly during use, and may affect the skin's experience, causing the skin to feel greasy. Generally speaking, the dosage of stearic acid should account for 3% - 8% of the total oil. Those who are new to soap production can try it from a lower proportion, such as 3%, fine-tuned according to the actual effect. If making moisturizing and moisturizing cold soap, the dosage of stearic acid can be slightly reduced; if the soap body is hard and rich in foam, the dosage can be appropriately increased to 6%
4. How to add stearic acid
Adding stearic acid to the soap solution requires a method. First chop the stearic acid, place it in a heat-resistant container, and melt it by water-proof heating. Water-proof heating can control the temperature evenly and prevent local overheating of stearic acid. When it is completely melted and in a transparent flowing state, slowly pour in the soap solution and stir quickly at the same time. Stirring should be continuous and uniform, so that the stearic acid and the soap solution are fully integrated. The stirring method is also particular. It can be clockwise or counterclockwise. Do not blink left and right, so as not to affect the uniformity of the soap solution.
5. Precautions after adding stearic acid
After stearic acid is added and stirred evenly, the state of the soap solution may change. It is necessary to pay close attention to the reaction of the soap solution, such as the saponification process and temperature fluctuations. If the saponification reaction is too fast and the temperature rises too high, the stirring can be suspended and cooled slightly to prevent the soap solution from overheating and "jelly" phenomenon, which will damage the quality of the soap. After entering the mold, the cold soap needs to be properly maintained. Place in a cool and ventilated place to avoid direct sunlight and high temperature. During the maintenance period, stearic acid and the soap are further fused to stabilize the characteristics of the soap. After about 3-4 weeks, the cold soap is mature, and the best results can be obtained by using it at this time.
The usage of stearic acid in cold soap, from the recognition of its characteristics, to the timing, dosage, method and follow-up attention of the addition, all Only in this way can we make high-quality cold soap, which is both practical and quality, and is a good product for cleansing the skin.
